Description

 Description Magnetic pole dispersion facing magnetic attachment Technical field

 The present invention relates to a magnetic attachment (adsorbent) for detachably joining an object using a magnetic attraction force. Background art

 As a conventional magnetic attachment, a cap-type magnetic attachment and a sandwich-type magnetic attachment are widely known.

 As shown in Fig. 21, the cap-type magnetic coupling has one magnetic pole on the adsorption surface 103 facing the object 106 to be adsorbed and conversely, the other magnetic pole on the back surface 104 side. And a soft magnetic material cap that bypasses the side surface around the magnet 101 from the magnetic pole on the back side 104 and faces the object 106 at the edge. And yoke 102 of the mold. In this case, a line of magnetic force loops from the magnetic pole on the back side 104 through the cap-shaped yoke 102 to the other magnetic pole opposing the object 106 via the object to be absorbed 06. Is formed, and a higher magnetic attraction force is exhibited than when the magnet alone faces the object to be attracted. Such magnetic attachments are disclosed in published patent publications such as Japanese Patent Application Laid-Open No. Hei 11-31045, Japanese Patent Application Laid-Open No. 2-29555, and Japanese Patent Application Laid-Open No. 2-295558. It has been disclosed.

 On the other hand, as shown in Fig. 22, the sandwich-type magnetic attachment consists of a magnet 201 with an N-S magnetization direction parallel to the adsorption surface 203 and abutting it from both N-S magnetic pole side surfaces. And a yoke 202 made of two soft magnetic materials sandwiched therebetween. In this case, a magnetic field line loop m is formed from one of the magnetic poles to the other magnetic pole through the yoke 202 which is in contact with the magnetic pole, through the to-be-adsorbed body 206 and through the yoke 202 on the opposite side to the other magnetic pole. Demonstrates even higher magnetic attraction. Such a magnetic arrangement is disclosed in a published patent publication such as Japanese Patent Application Laid-Open No. 4-227253.

 Conventional cap-type and sandwich-type magnetic attachments

Corrected form (Rule 91) As described above, the magnetic field line loop m forms a one-magnetic-path structure. Therefore, as shown in Fig. 23, even if they are made of the same magnet and have the same external shape with the same cross-sectional area and height as shown in Fig. 23, they are smaller than the magnet with the open magnetic circuit structure shown on the left in the figure.ぃ It exerts magnetic attraction.

 However, in the conventional magnetic coupling, as shown in Fig. 24, a phenomenon that the magnetic attraction force is close to saturation is seen, and when the height is increased only with the same metamorphic shape, a certain degree is obtained. The above does not contribute to improving magnetic attraction. This is because the line of magnetic force cannot exceed the saturation magnetic field density of the yoke, so that if the yoke is in a state of stiffness, the height of the yoke and the yoke may increase even if the height of the yoke is small. It is considered that the magnetic field lines in c do not increase. Therefore, SJS is economically to keep the height of the magnetic attachment high enough to start saturation of the magnetic attractive force, and even if the magnetic attachment force is increased beyond that, the magnetic attractive force can be expected to improve. L,,

 Conversely, when the height of the magnetic attraction is reduced from the vicinity where saturation of the magnetic attraction begins, and a thin magnetic attachment is manufactured, the saturation magnetic flux density of the yoke is much lower, as indicated by the side of ¾ ^ 3 2 \. Only a low density magnetic field line loop / could be formed. However, there was a drawback that the magnetic absorption in the book-shaped magnetic attachment 1 was considerably weakened. However, when the height of the magnetic attachment is strictly limited by the use conditions and applications, there often occurs a problem that a required magnetic attraction cannot be exerted. Disclosure of the invention

 In view of the above, it is necessary to solve the problem of providing an opposed-collecting magnetic attachment or a ment according to the present invention, which has a very low profile and a low profile, and has a sufficiently strong magnetic attraction. Section ¾.

 [Means for solving section communication]

 The magnetic pole dispersed counter type magnetic cartridge according to the present invention is a plate-shaped or sheet-shaped magnetic element having one surface serving as a suction surface.

It is formed of one of the permanent magnet and the I * magnetic material, and is formed of a large number of pillars and / or at least one wall. The side face is located at a distance of R3 from the side face of the other pillar-shaped part and the wall or the wall-shaped part, and each face of the pillar-shaped part and the wall or the fushiro forms a part of the adsorption surface. A first magnetic member;

 The Tfi 'surface is formed of one of the permanent magnet and the ¾ 钦 magnetic material and fills the side surfaces of the columnar portion and / or the ¾-shaped portion forming the first magnetic member, and the Tfi' surface is the remaining of the attraction surface. And a second magnetic member having a sheet shape together with the first magnetic member, and a back surface facing away from each top ffi forming an attraction surface of the i-th magnetic member and the second magnetic member. The first magnetic member or the second magnetic member formed of the permanent magnet and composed of the permanent magnet and the back side member formed of the magnetic material and facing the suction side surface. It is characterized in that the surfaces are all N-pole or S-pole, and all the surfaces facing away from the top surface are the same I * of the other N-pole or S-pole. Here, a permanent magnet with a large maximum energy product such as a rare-earth magnet is used. The top surface of the first magnetic member and the top surface of the magnetic member is covered with a thin corrosion-resistant surface, a thin surface, a thin plate, etc., and is adsorbed through this. Further, the second magnetic member covering the side surface of the first magnetic member does not necessarily need to be in close contact with the side surface of the first magnetic member. Further, a gap or a non-magnetic material may be interposed between the members.Moreover, the shape of the top of the first magnetic member is not particularly limited. Similarly, the cross section may change in the direction of the height 磁性-of the first magnetic member, and for example, a tapered first magnetic member may be used. (1) The magnetic member does not have to be parallel to 1 magnetic member may be disposed.

It is to be noted that the top surface of the even wall portion formed of the first magnetic member or the second magnetic member can be exposed on the attraction surface. In this case, the top surface of one wall-like part exerts the adsorbing power on all parts of the wide absorbent surface, so that the top surface of this wall-like part is partly attached to all parts of the suction surface. _Π that has a curved drawn wall shape with

A first magnetic member as the permanent magnet, a second magnetic member as the ferromagnetic material, a second magnetic portion The material and the backside member may be integrally formed, and may be a plate-like body having a portion for holding the first magnetic member on the suction surface side. The second magnetic member is formed by a perforated plate having a large number of through holes, and the first magnetic member is integrally held in each of the perforated holes of the perforated plate. Members can also be arranged.

 In addition, a first block having a predetermined shape is formed by one columnar portion or one wall recess forming a part of the first magnetic member and a part of the second magnetic member, and the first block is formed. A plurality of first magnetic members and second magnetic members having an overall sheet shape may be arranged in a plane pattern. Further, the first magnetic member is used as the permanent magnet, and one pillar-shaped portion or one wall-like portion forming a part of the first magnetic member, a part of the second magnetic member, and a back side. A second block having a constant cross section may be formed with a part of the member, and a plurality of the second blocks may be arranged in a plane to form the magnetic pole dispersion opposed magnetic attachment of the present invention. Means for fixing the blocks include means for fixing the blocks together by laser beam welding or electron beam welding, and cases where the outer peripheral surfaces of a plurality of three-arranged blocks are removed except for the suction surface. There is a means to provide and fix it, etc. ¾The case is preferably made of a corrosive material.

 The pole-dispersed opposed magnetic attachment according to the present invention may be formed of a case made of a corrosion-resistant material, and may have a configuration in which the entire periphery excluding the adsorption surface is opened. Further, the first magnetic member and the second magnetic member can be brought into contact with each other via a nonmagnetic material layer. The magnetic pole-dispersion opposed magnetic attachment of the present invention has a plate-like or sheet-like shape, and can be extremely thin as compared with a conventional magnetic attachment. For example, the thickness may be less than 2.0 mm and the thickness may be less than 0.2 mm.

 There is no limitation on the to-be-adsorbed body in the magnetic-shear-dispersion-type magnetic attachment of the present invention. Therefore, usually, a flat plate made of a 钦 -magnetic material is often used for the object to be attracted, but a material having a different structure and material may be used. For example, it is also possible to use the magnetic pole dispersion facing type magnetic attachment of the present invention as an object to be adsorbed. In this case, the two opposed collecting type tt ^ attachments are in contact with each other with their adsorption surfaces in contact with each other, so that a stronger magnetic attraction force can be obtained than in the case of using a normal magnetic material. You can expect.

A thin plate with an extremely thin magnetic material can be used as the object to be adsorbed. Traditional Even a thin adsorbent to the extent that a strong adsorption force could not be obtained by magnetic attachment, the strong adsorption power of Kiki can be obtained. The thickness of the pole IW of the object to be absorbed depends on the saturation magnetic flux density of the magnetic material constituting the object to be adsorbed. The opposed-collected magnetic attachment of the present invention, which can be as thin as the thickness, has a structure in which the first magnetic member, the second magnetic member, and the back-facing member are separately formed. It is also possible to assemble or integrate a member formed of a magnetic material into one body, and later clarify a member formed of a permanent magnet.

 A step of forming an M-shaped portion or at least one groove portion on the surface of a plate made of a magnetic material; a step of filling the Bfl portion and the groove portion with a magnet material serving as a permanent magnet; The surface of the material is removed and the surface of the magnet material is interposed between the permanent magnet and the table ifii of the plate material. The magnetic pole dispersion facing type of the present invention is obtained by making the magnetizing pole S, in which all the negative poles of the N pole or the S pole are the other poles of the N pole or the S pole on the back side opposite to the N pole or the S pole. The magnetic coupling may be made in S5,

 Furthermore, 钦 a number of columnar members with a constant cross-section separated from the other side where each side is in contact with either the magnet material that becomes permanent magnet or the 体 magnetic material that is the backside ¾ 30 ′ made of a magnetic material And / or at least one r-plane forms a fixed ¾-shaped portion, and the gap between the columnar portion and the ま た or the bunk-off portion is determined by either the magnet material or the soft magnetic member. A filling step, removing the tiri portion from the table, forming an attraction surface on which both the magnet material and the magnetic material are exposed, and a forming step, and a surface, on which the magnet material is magnetized and exposed. A magnetizing step in which all the poles of the N pole or S pole are set to the other pole of the NS or S pole, and the opposite side of the pole is set to the other pole of the N pole or S pole. You can also.

In the opposed collecting magnetic attachment according to the present invention, as described above, one of the i-th magnetic member and the second magnetic material formed of the permanent magnet is connected to the end IS on the attraction surface side. All form one part of the adsorption surface with the same negative pole of the N * or S pole, and the other end face opposite to the negative end face is all the same as the same negative pole of the N pole or S 1 *. Has become. And a 背 back-facing member made of a magnetic material 体 a ¾back-facing member on the other end face facing the one end face of the permanent magnet. The other of the _n-th magnetic member or the second tt member, which is in contact with the other magnetic pole and is formed of a magnetic material, forms another part of the attraction surface at its end face, The other end facing this is in contact with the back-facing member.

 Therefore, when the object to be attracted is brought into contact with the attracting surface of the magnetic pole dispersed facing magnetic attachment according to the present invention, it is radiated from one end surface of the permanent magnet which faces a part of the attracting surface and forms the --magnetic pole of the permanent magnet. The lines of magnetic force pass through the inside of the object to be attracted, are introduced into the magnetic material forming another part of the attracting surface, penetrate therethrough, and then pass through the dorsal side member made of the magnetic material. , Flow to other poles of permanent magnet. As described above, a closed magnetic circuit including the object to be attracted is formed, and a magnetic attraction force is generated. Here, in the permanent magnet, one end face of the attraction surface side is a negative pole of the s-pole or the N-pole, and a plurality of first magnetic members are disposed at a distance from each other. Therefore, a plurality of magnetic field loops (magnetic circuits) having a small loop between the first magnetic member and the second magnetic member in the attraction ffl and having a very small loop as compared with the conventional loop are formed, or a very small loop is formed. The line of magnetic force loop extends continuously,

 Such a magnetic field line loop is formed as a set for each of the first magnetic members, or is formed as a continuous extension, so that it flows into one or a part of the first magnetic members. Alternatively, even if the magnetic attraction force flowing is not large, the magnetic pole dispersed facing magnetic actuator of the present invention can exert a strong magnetic attraction force. The extremely small size of the magnetic loop means that the backside member made of a magnetic material needs to be thin, and the first magnetic member and the second magnetic member made of a magnetic material and a permanent magnet. The magnetic material can be used near the saturation magnetic flux density even if the height of the gangrene on the adsorption surface is low,

Accordingly, in the magnetic pole dispersion opposed magnetic attachment according to the present invention, by disposing a plurality of first magnetic members spaced apart from each other, a permanent magnet having a low height can be used. With magnetic flux supplied by the company, the ferromagnetic material can be used as a yoke (yoke) to guide the magnetic field lines in a state very close to saturation. Therefore, the pole-dispersion-facing magnetic attachment of the present invention can exhibit a magnetic attraction not inferior to that of a conventional magnetic attachment, although it is thin and low in height. As a result, the magnetic attraction force per unit volume is significantly improved, In addition, since the magnetic loop passing through each first magnetic member is small and the absolute amount of magnetic flux is small, the size of the object to be attracted required to pass the magnetic flux line loop in a state close to magnetic flux saturation can be reduced.

 In addition, the corrosion-resistant case not only isolates the magnets from the surrounding corrosive environment, but also functions as a solid structure to fix and fix each component.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a pole-dispersion opposed magnetic attachment according to an embodiment of the present invention will be described with reference to FIGS. Here, among the practical examples, Example 24 is an example of numerical calculation based on a mathematical model.

 (Example I: Number of first magnetic members N 4-2 x 2)

As shown in Fig. 1, the magnetic pole component I0 of this embodiment has four permanent magnets in two rows and two rows in pink, as shown in Fig. 1.

That is, the pole-dispersion opposed magnetic attachment 10 of this embodiment is formed of a permanent magnet, and one end faces 41 (not shown) to 44 form the attraction side faces 4 and are spaced apart from each other. The 1st magnetic member 1 1 1 4 arranged on the side and the side surface intersecting with one end surface 4 1 4 4 of the 1st magnetic member 1 1] 4 formed of a magnetic material. 1 1 magnetic member 1 1 1 4 and the other end of the second magnetic member 2 facing away from the suction side 4 and the other end facing the suction side 4 of the second magnetic member 2. And the back side member 3 formed of a magnetized body. The first magnetic members 11 1 to 14 formed of permanent magnets are formed by the--嬝 surface 4 1 4 4 of the attraction side surface 4. Are all the same pole (S pole), and the other end face opposite to this one end face 4 1 to 4 4 is all the same as the other end * (N pole). 1 Magnetic material 1 1 1 4 is permanent magnet A stone, The second magnetic member 2 and the back-facing member 3 are integrally formed of a magnetic material, and a plurality of (four) bottomed holes 2 in which the first magnetic member 1 to 14 are fitted and held on the suction side surface. ! It is a magnetic pole dispersion opposed magnetic attachment which is a plate-shaped body 20 having 〜24.

Dimensions of pole distributed opposing magnetic Atatchime down sheet 1 0 of the present embodiment, the aspect which respectively 3 mm, height 0.7 was _u is mm connexion This square suction side 4 of the area 9 mm ² This is a 0.7 mm thick plate-shaped magnetic attachment. The adsorbed body 9 assumed to calculate the magnetic attraction force of the magnetic pole dispersed opposed magnetic attachment 10 of the present embodiment is made of a magnetic material having the same length and width and a plate thickness of 0.35 mm. It is a flat plate.

For convenience of explanation, the pole-dispersion opposed magnetic head 10 of this embodiment is divided into two equal parts by the number of rows of the first magnetic member, and equally divided horizontally by two, as shown in FIG. It is divided into rectangular parallelepipeds. In the figure, a rectangular parallelepiped including the first magnetic member 1 as a representative, and the adsorbed body 9 at a portion abutting on the attraction side surface 4 are shown. and _n and a second magnetic member 2 and the facing away side member 3 consists炊磁resistance body formed integrally, the second magnetic member 2 and the facing away side member 3, one of the first magnetic member 1 A block 8 made of a magnetic material having a square bottomed hole 2 1 holding 1 is formed. Therefore, in the pole-dispersion opposed magnetic sensor 10 of the present embodiment, the blocks 8 are formed integrally by being arranged in two rows in a vertical direction and two columns in a row, that is, four blocks. Can also be considered.

The above-mentioned block 8, the first magnetic member 11 and the to-be-adsorbed body 9 have the same vertical dimension as shown in FIG. 3, that is, the shape of the block 8 is 1.5 horizontal. mm and a height of 0.7 mm, and the shape of the bottomed hole 21 and the first magnetic member 11 drilled into this is a rectangular parallelepiped of 1 mm in length and 0.4 mm in height. Therefore, a second magnetic member 2 having a thickness of 2 mm is provided on the front, rear, left and right of the first magnetic member 11 so as to extend on four side surfaces of the first magnetic member 11. the other end face of the N-pole side of the first magnetic member 1 1 of over蟪而4 1 and facing away from forming a section, _t the thickness 0. 3 mm back to back side member 3 is in contact,

According to such a configuration, the lines of magnetic force m coming out of the N pole of the first magnetic member 11 composed of the permanent magnet repel each other and spread to the peripheral part in the dorsal side member 3 to reduce the saturation magnetic flux density. It flows through the second magnetic member L> at a near high density, is released from the firewood side surface 4 and is guided to the object 9 to be adsorbed. Then, the magnetic field lines m flowing into the to-be-adsorbed body 9 are attracted to the S pole of the first magnetic member 11 while repelling to the magnetic field lines of the surrounding blocks (not shown), and penetrate through the to-be-adsorbed body 9, The magnetic flux returns from the adsorption surface 4 again to one end surface of the first magnetic member I 1) 1 to the S pole.

(Example 2 _: Individual teaching of first magnetic member N-I 6-4)

 The pole-dispersion opposed magnetic attachment (not shown) of this embodiment incorporates 16 permanent magnets in four rows vertically and four columns horizontally, and is similar to the above-described embodiment. Is the suction side that contacts the object to be sucked: Magnetic attachment of the dog. This was formed with permanent magnets! 6, comprising a first magnetic member of a pair, a second magnetic member formed of a magnetic material, and a dorsal member.

 That is, the magnetic pole dispersion opposed magnetic attachment according to the present embodiment comprises 16 first magnetic members which are formed of permanent magnets, one end surface of which forms an attraction side surface, and which are spaced apart from each other; A side surface formed of the first magnetic member and intersecting with the end surface of the first magnetic member; and a plate-like second magnetic member composed of six first magnetic members, and a suction side surface of the first magnetic member and the second magnetic member. The first magnetic member made of a permanent magnet is made up of a suction side that is opposite to the suction side and a back side member that is formed of the same magnetic material that faces the back. The end faces are all the same pole (S pole), and the other end face opposite to this end face is the same pole (N pole) of the other,>

 In other words, in this embodiment, は (the i-th magnetic members are permanent magnets, the second magnetic member and the back-facing member are formed integrally from a soft magnetic material, This is a magnetically dispersive opposed magnetic core which is a plate-like body having 16 bottom holes on which the magnetic member is fitted and held.

The outer dimensions of the pole-dispersion opposed magnetic attachment of this embodiment are 3 mm in length and width, and 0.350 mm in height. Therefore, this is the same as that of J1 in that the suction side surface is a square with an area of 9 mm ² , and the force is reduced by half, and the height is reduced by half to 0.35 O mm. By the way, the adsorbed body assumed to calculate the magnetic attraction force of the magnetic pole dispersion opposed magnetic attachment of the present embodiment is 0.175 mm in thickness and width and the same dimensions. ^ A plate made of a magnetic material. For convenience of explanation, if the magnetic pole dispersion opposed magnetic attachment of the present embodiment is divided equally into four by the number of rows of the first magnetic member and equally divided by four horizontally, it is divided into a cube. . This rectangular parallelepiped is composed of a first magnetic member made of a permanent magnet, a second magnetic member made of an integrally formed diamagnetic material, and a back-facing member, as in the first embodiment. . The second magnetic member and the back-facing member form a block made of a magnetic material having a square bottomed hole for holding one first magnetic member. The magnetic pole-dispersed opposed magnetic attachment can be regarded as a unit formed integrally with this block force, four rows vertically and four columns horizontally, that is, 16 pieces arranged in a plane.

The shape and dimensions of the block, the first magnetic member, and the object to be attracted are as follows. _T , that is, the shape of the block is (）) 7 mm) mm. The shape of the bottomed hole and the I-th magnetic member drilled in this is a rectangular parallelepiped with a height of 0.555 miii and a height of 0.20 mm. Therefore, there is a second magnetic member having a thickness of 0.1 mm on the front, rear, left and right sides of the first magnetic member, which covers four side surfaces of the first magnetic member. A backside member having a thickness of 0.5 mm is in contact with the other end face on the N pole side opposite to one end face of the first magnetic member. That is, this block π ·· and the first magnetic member held in the bottom hole of the block were similar to those described in Example 1 with reference to FIGS. Therefore, according to such a configuration, a magnetic flux line loop similar to that of Embodiment 1 is formed for each of the i G magnetic members, and a high magnetic flux density close to the saturation magnetic flux density is maintained from the adsorption side surface. Lines of magnetic force are emitted with the current. Therefore, the magnetic pole-dispersion opposed magnetic attachment according to the present embodiment uses a much lower object and a much thinner object to be adsorbed, and is not inferior to the conventional high magnetic attachment. I can show my strength.

 (Embodiment 3) Even number of first magnetic members N: 1 5 6-■ = 1 6 1 6

The pole-dispersion opposed magnetic attachment (not shown) of the present embodiment has 256 rows of permanent magnets in 16 rows vertically and 16 rows in apples, similar to the previous embodiment. One side is a plate-shaped magnetic attachment that serves as an adsorption side surface that is in contact with the adherend. It is composed of a 2 5 6 first magnetic邹材formed by the permanent magnet, the second magnetic member and facing away member formed of钦磁material elements _t,

 That is, the pole-dispersion opposed magnetic attachment of the present embodiment is formed of permanent magnets. The end faces form the attraction side surfaces and the 256 first magnetic poles are spaced apart from each other. A second magnetic member formed of a magnetic material and having a side i intersecting the negative end face of the first magnetic member and having a plate-like shape with 256 first magnetic members; and a first magnetic member and The other end of the second magnetic member facing away from the attraction side is composed of a “resonant side” and a back-facing member formed of the same magnetic material facing the opposite side. In addition, in the first magnetic member formed of a permanent magnet, all of the one end face on the attraction side face becomes a zonal pole (St *), and all the other end faces opposite to this one end face are the same as the other. ).

 In other words, in this embodiment, the 2 Γ) six primary members are permanent magnets, and the second magnetic member and the back-facing member are integrally formed from a D magnetic material. This is a magnetic pole dispersed opposed magnetic attachment which is a plate-like body having 256 bottomed holes into which the first magnetic material is fitted and held.

The external dimensions of the pole-dispersion facing type-magnetic attachment of this example are 3 mm in length and width, and 0.0875 mm in height, so that the absorption side has an area of 9 mm ² . The shape of the square is the same as that of Jeongjeong example 1.2, but the height further diminishes, resulting in an extremely thin plate-shaped magnetic attachment of 0.08 "") nun. The adsorbed object assumed to calculate the magnetic attraction force of the dispersion-facing magnetic attachment is a flat plate made of a 钦 magnetic material having the same length and width and a thickness of 0.04375 mm. For convenience of explanation, the magnetic pole distributed facing type magnetic contact of the present embodiment is divided into 16 equal parts vertically in the number of rows of the first magnetic member, and equally equal I 6 parts in the horizontal direction. Is divided into rectangular parallelepipeds. As in the case of the first embodiment described above, this solid body is composed of a first magnetic member made of a permanent magnet, an integrally formed second magnetic member made of a magnetic material, and a back-facing member. The second magnetic member and the back-facing member form a block made of a magnetic material with a bottomed hole having a square cross section for holding one first magnetic member. In the present embodiment, the tt pole dispersion pair 13 magnetic coupling is formed by integrally forming the blocks 1G rows vertically and〗 6 columns horizontally, that is, 256 blocks. Can also be considered,

 The shape and dimensions of the block, the first magnetic member and the object to be attracted are as follows. That is, the shape of the block is a rectangular parallelepiped of 0.1875 m ni. In height and width, and 0.875 inm in height. The shape of the bottom hole drilled in this and the shape of the first conductive member are as follows. Therefore, the first magnetic member has front and rear and left and right sides with a thickness of 0.1 mm (> 25 in m). In addition, the first magnetic member has four side surfaces, and the other end surface on the N pole side, which is opposite to one end surface of the first tt member, which is a part of the adsorption side surface, has a thickness (). The backside member of 37.5 mm abuts, that is, the first flexible member held in the bottom hole of the block and the ridge block is shown in FIG. 2 and FIG. : Similar to that described with reference to i, with each dimension reduced to 1/8.

Therefore, according to such a configuration, the magnetic field loops of Example and Example are formed for each of the 256 magnetic first magnetic members, and the high magnetic flux density close to the adsorption side surface or the saturation magnetic flux density is maintained. _n Hence the the left magnetic field lines are emitted, magnetic poles distributed opposing magnetic § evening of the ¾施例Tsuchime down I 'is a very low height, and while using a very thin object adsorbent, conventional high A magnetic attraction that is not inferior to that of a magnetic attachment that has a high level can be achieved.

The dimensions, magnetic properties, materials, etc. of each component of the magnetic pole-attached magnetic attachment of this embodiment are shown in the following table:! It is as shown. In this table, the object to be adsorbed and the block (dimensions are only outer dimensions) are also listed. " [Table 3]

 The pole-dispersion opposed magnetic attachment of this embodiment having such a configuration has a height ().

It was calculated that at 0 875 mm, it could exert a magnetic << 8 attraction of 288 C gfj. By the way, the height (sheet thickness) of the wound body used in the calculation was 0.043375 mm, and the total height was the same even if the magnetic pole-dispersed facing magnetic attachment and the magnetic head were combined. The thickness is only 0.13 1 25 mm. In addition, the volume V of the opposed-integrated magnetic attachment in this embodiment is 0.78 7 5 [rn in ³ I, and the magnetic attraction force per unit body is 3666Γκf / mm. ³ ]. By the way, the total yield V 'including the object to be adsorbed is 1. 18 1 2 ") [mn ^], and the magnetic attractive force 申,', Ζν 'was 2 4 4 (gf / mm ³ J).

 (Protrusion 4: Number of first magnetic members N = --10, 00-100-100 x 100) The magnetic pole dispersion opposed magnetic attachment (not shown) of the present embodiment is 100,000 permanent magnets with 100 rows and 100 columns are built in the woodworker. It is a magnetic attachment. This is composed of an I.sup.th (10.0) -th magnetic member formed of a permanent magnet, a second magnetic member formed of a 钦 magnetic material, and a back-facing member.

 That is, based on the same technical idea as in each of the above-described embodiments, 100,000 first magnetic members made of permanent magnets, And a back-side member for holding the same in the same magnetic pole direction and in parallel.

 In other words, in this embodiment, the first magnetic member of 100. () 00 is a permanent magnet, and the second magnetic member and the back-facing member are formed from a magnetic material at rest. Further, the magnetic pole dispersion opposed magnetic attachment is a plate-like body having 100,000 bottomed holes in which the first magnetic member is fitted and held on the suction side S.

The external dimensions of the pole-dispersion opposed magnetic attachment of this embodiment are 3 mm in length and width, and 0 to 14 mm in height. Was it -, Te this is in terms of forming a square suction sides of the area 9 mm ² is similar to the embodiment described above, very harbor have shaped magnetic Atta Tchime height slightly 0. 0 1 4 mm It is a point. Incidentally, the object to be attracted for calculating the magnetic attraction force of the magnetic pole-dispersion opposed magnetic attachment of the present embodiment is a flat plate made of a magnetic material having the same width and a plate thickness of 0.007 mm. It is.

 The magnetic pole dispersion opposed magnetic attachment according to the present embodiment can also be considered to be divided into 10.0000 rectangular parallelepipeds by dividing each longitudinal jig into 100 equal parts. This rectangular parallelepiped has the same configuration as the rectangular parallelepiped of each of the above-described embodiments, is a similar shape in which only the dimensions are uniformly reduced, and has the same operation. However, the magnetic pole dispersion opposing magnetic attachment

I 8 It can also be considered that this rectangular parallelepiped is formed as a unitary body having 100 horizontal sides, that is, 100,000 horizontal planes.

By the way, the shape and dimensions of each component of the above-described rectangular parallelepiped are as follows. In other words, the shape of the block made of magnetic material is a rectangular parallelepiped with a height of 0.03 mm and a height of 0.014 mm, and a bottomed hole drilled in it and a permanent magnet held in it. The shape of the first magnetic member is a rectangular parallelepiped having a height of 0.022 mm and a height of 0.008 mm. Therefore, there is a second magnetic member having a thickness of 0.04 mm on the front, rear, left and right sides of the first member, covering the four sides of the first magnetic member. to the other end face of the N棰側to one end surface facing away of the first magnetic member having, i.e. _π turned away side member thickness 0 0 6 mm is in contact, a bottomed hole in the block and the block The held first magnetic member is similar to that described in Example 1 with reference to FIGS. 3 and 3, and has dimensions of 1/50.

 Therefore, according to such a configuration, a magnetic flux line loop similar to that of Example 1 is formed for each of the 100,000 first magnetic members, and a high magnetic flux density close to the saturation magnetic flux density can be obtained from the adsorption side surface. Lines of magnetic force are emitted while maintaining this. Therefore, the magnetic pole-dispersion opposed magnetic attachment according to the present embodiment uses an ultra-thin shape and ultra-thin object to be attached, and is about several percent inferior to the conventional high-attachment magnetic attachment. A strong magnetic attraction can be demonstrated.

 Table 4 below shows the specifications of the components, such as the magnetic pole dispersion opposed magnetic attachment according to the present embodiment, such as the shape and dimensions, magnetic characteristics, and materials. In the wooden table, the adsorbents and blocks (dimensions only) are also listed.

 It was calculated that the magnetic pole dispersion opposed magnetic attachment of the present embodiment having such a configuration can exhibit a magnetic attraction force of 116 [gf] at a height of 0.014 mm. Incidentally, the height (plate thickness) of the object to be adsorbed used in the calculation is 0.007 mm, and the total height is 0.02 even if the magnetic pole dispersion opposing magnetic attachment and the object to be adsorbed are combined.

Here, in order to further clarify the effect of the opposed ife 穑 type magnetic attachment of the present invention, a comparative magnetic attachment according to the prior art was manufactured. This magnetic attachment as a conventional example has a single permanent magnet 10 I and the entire outer periphery of the permanent magnet 101 except for the fertilization side, as shown by ^ 121 in its entirety. It is assumed that the main part is composed of a yoke 102 that covers the surface. The external dimensions of the magnetic attachment body are 1.4 mηι and the height and width are 3 mm. Each dimension is set to be similar to a rectangular parallelepiped formed by a imaginary permanent magnet で and a magnetic material block holding the permanent magnet imagined in each embodiment described in ti, and the area of the suction side surface is set in each embodiment. It is set to the same pole distributed pairs oriented magnetic Atatchime down bets and 9 〖mni ^z I. Incidentally, the plate thickness of the adsorbed body I 06 was similarly set to 0.7 mm.

As a result, magnetic attraction! ⁷ 3) 5 C gf) and is calculated, whereas since the volume V of the magnetic attachment main emission Bok is also 1 2. 6 m ^lambda, only two magnetic attraction force F ./V per unit volume 6. 6 [«f / mm ³ I By the way, the total volume V 'including the object to be adsorbed is 18.9 rn rn m ³ 1, and the magnetic attractive force per unit volume obtained based on this is The FZV 'was 17.7ίκΓ / mm ³ j.

 (Comparison)

H. For the conventional example described above and the first to fourth embodiments of the present invention, the number (number of permanent magnets) N of the t-th magnetic member, the height H of the magnetic attachment, and the volume V are as follows. Table 5 below shows the magnetic attraction force F and the magnetic attraction force F / V per unit volume as--Ksfe, as the performance that was demonstrated by the magnetic member with a simple configuration.

[Table 5]

 List of main specifications of conventional examples and {Examples} to 4]

As is evident from Table 5, as the number of magnetic members I (the even number of magnets) N increases, both the height H and the physical fitness V drastically decrease in inverse proportion to the square root of N. In contrast, the magnetic attraction force F is not so degraded by _π Therefore, as a result, the magnetic attraction force per body F / V is dramatically improved as the first magnetic member is integrated. Understand

 Thus, it has been revealed that the magnetic S-dispersion opposed magnetic attachment of the present invention can provide a magnetic attachment that exhibits a sufficiently strong magnetic attraction even though it is thin.

 (Supplementary comparison)

For reference, for each of the above examples, the total height (H10t), which is the sum of the height of the magnetic attachment Η and the plate ^ t, and the magnetic attachment The resting edge V ', which is the sum of the volume V and the volume of the object to be adsorbed, and the magnetic attraction force per unit body 全体 of the total volume are shown in Table 6 below. [Table 6]

 [Conventional example and Example! List of specifications including the adsorbents of ~ 4)

 As is apparent from Table 6, even when the plate volume of the object to be adsorbed is taken into account, the same tendency as that of the above-mentioned opposed integrated magnetic attachment is exhibited. That is, as the number N of the first magnetic members composed of the permanent magnets increases, the total height (H + t) and the total volume V ′ both decrease sharply in inverse proportion to the square root of N. On the other hand, the magnetic attraction force F does not decrease so much, and the magnetic attraction force per unit volume F Z V ′, on the contrary, greatly increases. Figures 4 and 5 show the situation.

That is, as shown in FIG. 4, even if the number N of the first magnetic member is increased and the overall height (H10t) is reduced, the total S (H + t) is reduced to N = 10% in the conventional example. No noticeable decrease in the magnetic attraction force F was observed until about 10: 1, and when the number N of the first magnetic members was further increased to reduce the thickness, the magnetic attraction force F decreased rapidly. It is expected to go. The height H of the magnetic attachment is 2 to 3 of the total height (H + t) in each of the examples described in the H description, so the height H has the same tendency. In addition, as shown in Fig. 5, up to about N ---- 100 It can be seen that the magnetic attractive force FZV 'of the second magnetic member increases almost in proportion to the square root of the number N of the magnetic members. After about N-100, it can be seen that the FZV 'elongation tends to slow down. The force <increases as N increases. By the way, since the total volume V 'is five times the volume V of the magnetic attachment, it can be said that the magnetic attraction force FZV per unit volume tends to be the same as FZV'.

 Therefore, according to the present invention, while thinning the magnetic poles, the thickness (height) of the first magnetic members is reduced to about 1/10 of that of the conventional magnetic poles and the magnetic attraction force is not significantly reduced. It has become clear that a magnetic attachment can be provided. And if you can tolerate a certain decrease in magnetic attraction, you can further increase the harvest (the number N of magnetic members I) and further reduce the thickness. In addition, according to the magnetic pole-dispersion opposed magnetic attachment of the present invention, by increasing the degree of integration, the magnetic attraction force FZV per unit volume is extremely high and high performance is achieved. It was found that magnetic attachment could be provided.

 Here, the object to be adsorbed, which is not limited in the present invention, will be briefly mentioned. As described above, the plate thickness t of the object to be adsorbed is set to half the height H of the magnetic attachment in each of the embodiments and the conventional example. Sufficient magnetic attraction can be exerted by the magnetic pole dispersed facing magnetic attachment of each of the aforementioned examples. It is possible to use an adsorbent with a smaller thickness, but in that case the magnetic attractive force will be somewhat lower. However, this is not limited to the case where the to-be-adsorbed body is made of a material having a higher saturation magnetic flux density than the second magnetic member and the back side member in each of the above-described embodiments.

It is also possible to use the magnetic * dispersed facing magnetic attachment of the present invention as an object to be adsorbed. In this case, two magnetic pole-spreading-type magnetic attachments in which the magnetic poles of the first magnetic member are arranged in reverse are attached to each other with their adsorption side surfaces in contact with each other. than the magnetic attraction force of the embodiments, can be expected Hatsu挿of stronger magnetic attraction _π

By the above Examples 1 to 4, it has been clarified how the magnetic pole dispersion opposed magnetic attachment of the present invention is superior to the magnetic attachment according to the prior art. Therefore, the following introduces some practical examples. And shows the broad scope of the present invention >>

 (Example 5)

 As shown in Fig. 6, the magnetic pole dispersion type magnetic pole 1 mm of the present embodiment is composed of 11 rectangular rows and 6 horizontal rows, each of which is composed of six square pillar-shaped permanent magnets. The first magnetic members 1 to 166 are plate-shaped attachments in which one surface held by the second magnetic member 2 and the back-facing member 3 made of a ferromagnetic material is the suction side surface 4.

 That is, it is formed of a plurality (66) of the I-th magnetic members 11 to 16 6 formed of permanent magnets, one end ffi of which forms the attraction side surface 4 and is spaced apart from each other; The first magnetic member 1! The second magnetic member 2 having a plate shape with the first magnetic member 1 i to 16 6 having a side surface that intersects the −end surface of〗 6 66, the first magnetic member 11 1 to I 66 and The other end of the second magnetic member 2 opposite to the attraction side surface 4 has a large length, and the attraction side surface 4 has an opposite side member 3 formed of a non-magnetic material. Further, in this embodiment, the first magnetic members 11 to 16 G formed of permanent magnets have one end face on the attraction side 4 side as the same pole of one of the N pole and the S pole. The magnetic S-dispersion opposing magnetic flux characteristic is characterized in that the other end face facing the same is the same pole of the other of the N pole or the S pole.

The second magnetic member 2 and the back-facing member 3 are both integrally formed of a magnetic material, and the sixty-first magnetic members 11 1 to 16 6 are fitted and held on the suction side surface 4. It is a plate 20 with a bottom hole 21 to 26 6 of skill. Therefore, the magnetic pole-dispersion opposed magnetic attachment 10 of the present embodiment is provided with the cubic bottomed holes 21 to 26 fi formed in the adsorption side surface 4 of the plate-shaped body 20 made of a magnetic material. The first magnetic member 1 i to 16 6 having the same dimensions and made of a cube is made by inserting the magnetic poles in the same direction and inserting them until they come into contact with the bottom surfaces of the bottomed holes 21 to 26 6 Can _u

 Here, in the present embodiment, the bottomed holes 21 to 26 6 and the first magnetic members 11 to 1 66 are cuboidal, but they may be changed to a columnar shape or another shape for the convenience of machining. Does not matter.

The external shape of the magnetic pole dispersed opposed magnetic attachment 10 of this embodiment is a substantially rectangular flat plate having a length of 3.0 mm, a width of 4.0 mm, and a height of 0.2 mm as shown in the figure. The four corners have rounded corners. The to-be-adsorbed body 9 is a flat plate made of a diamagnetic material having a thickness of 0.1 mm and a surface shape identical to that of the attraction side surface 4. As can be seen from the above, according to the present invention, it is possible to provide an extremely thin magnetic pole dispersed opposing magnetic element 10 and its absorbed body 9.

 (Example 6)

 As shown in FIG. 7, the magnetic pole dispersion opposed magnetic attachment i 0 of the present embodiment is a plate-shaped magnetic attachment having a hexagonal hexagonal surface with one ffi serving as the adsorption side surface 4. That is, a plurality of (19) first magnetic members 11 to 1 19 formed of permanent magnets, one end surface of which forms an attraction side surface 4 and is spaced apart from each other by S; A second magnetic member 2 formed so as to cover a side surface intersecting with one end of the first magnetic member 11 1 to 1 19 and having a plate shape with the first magnetic member I 1 to 1 19, and a first magnetic member 1 1 19 and the magnetic pole dispersed opposition consisting of the back side member 3 made of a magnetic material facing the suction side 4 and the back side facing the suction side 4 of the second magnetic member 2 The type magnetic attachment 10. Here, as shown in FIG. 8, the first magnetic members 11 to 1 19 formed of permanent magnets have one end on the attraction side 4 side] iH 1 to 4 19 (partly shown) are all S poles. And the other end face opposite to one end face 41 to 419 is the same pole of the negative pole. As shown in FIG. 7 and FIG. 8 again, the second magnetic member 2 and the back-facing member 3 are integrally formed of a magnetic material, and the cylindrical first magnetic members 11 to 1 are formed on the suction side surface 4. A hexagonal plate-shaped body 20 having the same number of flat-bottomed round holes 21-1 to 19-19 as the number of flat-bottomed round holes to which 19 is attached and held.

 The characteristic of the pole-dispersed opposed magnetic pole 10 of this embodiment is that the plate 20 is hexagonal, the I 1 19 and the bottomed hole 21 1- In addition to the cylindrical shape of the 219, the first magnetic member] is in the arrangement rule of 1-1 I9. That is, in the present embodiment, the first magnetic members 11 to 1 19 are arranged such that an arbitrary triangle is formed by selecting any three matching members and connecting their respective center points. For example, as shown in FIG. 7, if three first magnetic members〗 are selected as 14 and 〖5 on the adsorption side 4, each of these center points is located at each vertex of the equilateral triangle Τ. .

According to such an arrangement, the first magnetic members 11 to 119 can be arranged on the attraction side surface 4 most closely, and the magnetic attraction force can be improved. Further thinning and improvement of the magnetic attraction force per unit volume will increase the even number of ridges on the first magnetic member. This can be easily realized. Alternatively, it is also possible to manufacture another planar magnetic nucleus dispersion opposed magnetic attachment other than a hexagon while keeping the arrangement rule of the first magnetic member of iii $.

 Drilling the bottomed holes 21 to 219 having such an arrangement from the suction side surface 4 of the plate-shaped body 20 can be easily performed using a known machine tool such as an NC precision ball. Accordingly, the magnetic pole dispersed opposed magnetic attachment 10 of the present embodiment is easy to manufacture, has a higher magnetic attraction (or magnetic attraction per unit body), and is suitable for a narrow space close to a circle. It can be easily arranged and used.

 The object to be adsorbed is not limited, and thus a flat plate made of a diamagnetic material is usually used. However, an object to be adsorbed having another configuration may be used. For example, if the magnetic pole dispersed facing magnetic attachment of this embodiment, in which the directions of the magnetic poles are all reversed, is used as the object to be attracted, a stronger magnetic attraction force may be exhibited.

 (Example 7)

 As shown in FIG. 6, the pole-dispersion opposed magnetic head 10 of this embodiment has a flat plate-like magnetic surface having a hexagonal surface, as shown in FIG. This is a schedule. First magnetic member 11 consisting of a columnar permanent magnet 1 1 to ι 19 Force, an array that forms an equilateral triangle when taking any three in contact with it, and a bottomed hole 2 in the second magnetic member 2 It is the same as in Example 6 in that it is arranged in 19.

 The difference from the sixth embodiment is that the second magnetic member and the back-facing member constituting the plate-shaped body 20 are initially manufactured separately. That is, as shown in FIG. 10, in the magnetic pole dispersion opposed magnetic attachment 10 of the present embodiment, the plate-shaped body 20 has a through hole forming a bottomed hole 21-2 19 (partly shown). Perforated plate portion 5 (second magnetic member) having holes 5 1 to 5 19 and one side 50 of perforated plate portion 5 are integrally shaded 81 to form the bottom of bottomed holes 2 1 to 2 19 Back plate 6 (rear-facing member). The perforated plate portion 5 and the back plate portion 6 are made of a magnetic material, and are integrally joined to each other at the joint surfaces exposed on the outer peripheral surface by electron beam welding, laser welding, or the like. Is formed. Therefore, as shown in FIG. 9 and FIG. 10, the welding portion W surrounds the entire outer periphery of the thin hexagonal columnar plate 20.

The pole-dispersion opposed magnetic attachment 10 of the present embodiment thus configured is It can be manufactured as follows.

 That is, first, cutting with a drill; : Punched through holes 51 to 519 in a hexagonal prism-shaped magnetic material having an appropriate height (thickness) so that the tool does not move, using an NC precision ball or the like. The magnetic material is sliced to produce a plurality of perforated plate portions 5. Alternatively, through-holes 5 to 519 are formed in a hexagonal pillar in which a plurality of hexagonal thin plates to be the perforated plate portion 5 are stacked and fixed, and a plurality of perforated plate portions 5 are manufactured at a time. Next, the back plate portion 6 cut out from the thin magnetic plate by a working method such as precision press or laser fusing is brought into contact with one surface 50 of the perforated plate portion 5, and the bonded surface of the two is pressed down. Are joined by electron beam welding or laser welding as described above. Then, in the through holes 51 to 519 that now form the bottomed holes 2 to 2 19, the cylindrical first magnetic material I1 to 119 made of a permanent magnet is inserted into the magnetic pole. Insert in the same direction until one end touches the bottom of the hole, and fix it. As the fixing means, there are means such as interference fit, fixing with an adhesive, and sealing with a cap yoke described later. After the first magnetic member is inserted and fixed, it is more preferable to grind or polish the suction side surface 4 so as to be close to a flat surface and to improve the adhesion with the object to be suctioned.

 According to the above-described manufacturing method, it is not necessary to form a large number of flat-bottomed holes having a precisely controlled depth in each of the plate-like bodies 20, and a plurality of hole plate portions 5 can be manufactured at a time. This has the effect of increasing productivity.

 (Example 8)

 Similarly to the above-described embodiment 7, the magnetic pole dispersion opposed magnetic attachment 10 of this embodiment also has a plate-shaped magnetic field whose hexagonal shape is a hexagonal surface as shown in FIG. It is an attachment.

 The magnetic pole dispersion opposed magnetic attachment 10 of this embodiment is different from that of the seventh embodiment in that, unlike the seventh embodiment, the first magnetic member 1! 1 to 19 are made of a magnetic material, and the second magnetic member 2 is made of a permanent magnet magnetized in the perpendicular direction with the attraction side surface 4.

That is, as shown in FIG. 11 and FIG. 2, the magnetic pole dispersion opposed magnetic attachment 10 of the present embodiment is formed of a magnetic material, one end surface of which forms the attraction side surface 4 and is spaced apart from each other. A plurality (1 9 倘) of the first magnetic members 11 1 to! i 9 and the first magnetic member 11-1 to 1 I made of permanent magnet!

 (Examples (Modifications of i to 8)

In the above-mentioned embodiment, it is ideal to design the dimensions of the member made of the magnetic material and the member made of the permanent magnet so that the member made of the magnetic material is close to the magnetic flux saturation density. However, due to various restrictions, it may not be possible. For example, in Embodiments 6 to 8, when there is room in the second magnetic member 2 and it is desired to concentrate the magnetic flux around the first magnetic members i 1 to 119, as shown in FIG. It is also possible to provide the magnetic member 2 with a plurality of II-type holes h. The star-shaped hole h is a hole with a three-pointed star-shaped cross section formed in the second magnetic portion W2 between any three first magnetic members that are in contact with each other. It is also possible to provide a bottomed hole with the bottom as the bottom, or to provide the rear-side member 3 as a poor through hole. Also, beneath the suction side 4 from the opening It may be a bottomed hole that narrows as it proceeds.

 By providing such a star-shaped bow h on the second magnetic member 2, the second magnetic member 2 is disposed substantially cylindrically around each of the first magnetic members 11 to 1 19, so that the magnetic field lines The loop is formed substantially axially symmetric around the first magnetic member 11 to 1 19. Since this is the most effective shape of the line of magnetic force lines, according to this modification, it is possible to maximize the magnetic attraction force per unit weight of the magnetic pole dispersed opposing magnetic attachment.

 (Consideration on tt resistance)

Pole distributed opposing magnetic Atatsu tree invention - ί · e n t a to桷成material is not necessarily _r is not necessarily the only ones having excellent «resistance, in particular a permanent magnet material, Star performance requirements were满In some cases, fcf erosion is not enough. On the other hand, corrosive gases and liquids may be present in the environment in which the product is used. Are used by body fluids. Extremely high heat resistance is required for safety requirements. The following measures can be considered as countermeasures against sales and corrosion.

 C 1) Use of cap yoke

 As shown in Fig. 20, one end surface 41 of the magnetic member 1 made of a permanent magnet is provided in parallel with the attraction side surface 4 so as to have a "-" step, and the attraction side surface 4 and the first magnetic member are provided. In the space created between the one end face 4 1 and 1, a thin plate-shaped cap chord Ci made of a corrosion-resistant material is placed between the second magnetic member 2 made of a similarly corrosion-resistant material. A slight gap is left between the cap yoke C 1 and the second magnetic member '2, and the thin gland between the cap yoke C 1 and the second magnetic member' 2 This is provided by providing a cap member made of a body C 2, and the suction side surface 4 of the second magnetic member 2, the cap yoke C 1, and the outer end surface of the cap spacer C 2 are flush with each other. And a suction side surface 4. A bonding surface between the suction side ifii 4 of the second magnetic member 2 and the cap yoke C1, and the cap yoke C The joint between i and the caps base C2 is welded from the outside of the suction side surface 4 by a beam welding or laser welding, and the first magnetic member 1 is hermetically fixed.

 Therefore, according to the above-described configuration, it is possible to isolate and protect a permanent magnet, which often has a particularly poor iH corrosion resistance, from an external corrosive environment.

The lines of magnetic force flowing into the one end face 41 forming the S pole facing the adsorption side 4 are non-magnetic. It flows in through the cap yoke C 1 made of a magnetic material, avoiding the cap spacer C 2 made of a body. Therefore, by the action of the cap spacer C2, it is possible to minimize the short circuit of the magnetic force lines flowing directly to the first magnetic member 2 without leaving the attraction side surface 4 from the second magnetic member 2. As a result, when the one end face 4 1 and the suction side face 4 are made to coincide with each other without using the cap yoke C 1, the magnetic attraction force is not inferior.

 (2) Other anti-corrosion measures

 The following means are conceivable as means for preventing and preventing other magnetic pole-dispersed opposed magnetic actuators.

 (1) Corrosion resistance, resin coating

 ②Coated with tree 8 or corrosion resistant metal (upper case includes use of case)

 As described in detail above, the magnetic * -dispersion opposed magnetic attachment according to the present invention comprises the first magnetic member or the second magnetic member formed of a permanent magnet having the same magnetic pole directed to the attraction side {δ}. By dispersing the magnetic poles of the magnetic member so as to oppose each other, it has the effect that a sufficiently strong magnetic attraction force can be exerted despite its extremely low profile and thin shape. As a result, there is an effect that the magnetic attraction force per unit volume can be greatly improved. In addition, there is an effect that it can be formed in any planar shape. Further, as an incidental effect, the thickness of the object to be adsorbed can be made thinner than the thickness of the magnetic pole dispersion opposed magnetic attachment according to the present invention, and even when the thickness of the object to be absorbed is extremely thin, sufficient magnetic properties can be obtained. A suction force is obtained.
