Description

  The present invention relates to an electromagnetic wave suppressor manufacturing method and an electromagnetic wave suppressor.

  In order to suppress electromagnetic waves generated from electronic parts, wiring, electronic devices, etc., a thin plate-like ferrite sintered body and a thin sheet-like flexible electromagnetic wave suppressing member must be disposed in the vicinity of the electromagnetic wave generation source. There is.

  Since the ferrite sintered body is usually a hard and brittle material, the thin plate-like ferrite sintered body is easily cracked. If broken pieces adhere to electronic parts, wiring, electronic equipment, etc., there is a possibility of causing malfunction or damage due to short circuit.

  For example, Patent Document 1 proposes a technique for laminating a ferrite sintered body so that fragments of the ferrite sintered body are not scattered around.

  The electromagnetic wave suppression body described in Patent Document 1 includes a ferrite sintered body, a double-sided tape that is mounted so as to cover the lower surface of the ferrite sintered body, and a protective tape that is mounted so as to cover the upper surface of the ferrite sintered body. Patent Document 1 further includes a protective frame material in which an electromagnetic wave suppressing body is disposed so as to surround an outer periphery of the ferrite sintered body, and the double-sided tape and the protective tape are bonded to the protective frame material. There is a statement that it will be provided.

  On the other hand, the electromagnetic wave suppressing member having flexibility is obtained by forming the electromagnetic wave suppressing body described in Patent Document 2, for example, into a sheet shape. The electromagnetic wave suppressor described in Patent Document 2 is a composite of soft magnetic powder and binder in which soft magnetic powder is dispersed in a binder. As described in Patent Document 2, chlorinated polyethylene, silicone rubber, ethylene-propylene-diene rubber, acrylic rubber, and the like are employed as the binder.

  Unlike the ferrite sintered body, such an electromagnetic wave suppressing member has flexibility and therefore hardly breaks, and there is a low possibility that fragments of the electromagnetic wave suppressing member are scattered around.

  However, in the case of the electromagnetic wave suppressing member having flexibility, it is formed into a large sheet, for example, and used by a method of cutting and sticking to a desired size. In such a case, the soft magnetic powder may spill out from the cut end. If the spilled soft magnetic powder scatters and adheres to electronic components, wiring, electronic equipment, etc., it may cause malfunction due to short circuit.

Japanese Patent No. 4492934 JP 2007-287840 A

  In order to prevent scattering of the spilled soft magnetic powder, it is conceivable to apply the laminating technique described in Patent Document 1 to the electromagnetic wave suppressing member. Specifically, it is conceivable to replace the ferrite sintered body contained in the electromagnetic wave suppressing body described in Patent Document 1 with an electromagnetic wave suppressing member.

  However, the ferrite sintered body is easily cracked as described above. Therefore, in the laminating technique described in Patent Document 1, it is necessary to arrange one by one so as not to break on the double-sided tape or the protective tape, and further arrange the protective frame material in correspondence with the ferrite sintered body. . Thus, since each of the ferrite sintered body and the protective frame material is arranged one by one, the laminating technique described in Patent Document 1 has a problem that the production efficiency of the electromagnetic wave suppressing body is poor.

The upper surface of the first upper adhesive layer 107b corresponds to one adhesive surface of the first double-sided sheet 102a. The lower surface of the first lower adhesive layer 107c corresponds to the other adhesive surface of the first double-sided sheet 102a.

  The upper surface of the first upper adhesive layer 107b is affixed to the lower surface of the electromagnetic wave suppressing member 101 with the contour aligned when viewed from above.

  The housing member 103 is a frame-like member that includes a through-hole penetrating vertically as a housing space. The accommodation space is a space for accommodating the electromagnetic wave suppression member 101 to which the first double-sided sheet 102a is attached.

  The housing member 103 is made of, for example, resin, rubber, and has flexibility. The accommodation member 103 according to the present embodiment is, for example, a rectangle having a side length of several centimeters when viewed from above. The height of the housing member 103 is the same as the height of the electromagnetic wave suppressing member 101 to which the first double-sided sheet 102a is attached, that is, the height of the first double-sided sheet 102a and the electromagnetic wave suppressing member 101 overlapped.

  The accommodation member 103 according to the present embodiment surrounds the side periphery of the electromagnetic wave suppression member 101 accommodated in the accommodation space with a gap. This gap is an interval in the front-rear direction or the left-right direction between the inner surface forming the accommodation space and the outer edge of the electromagnetic wave suppressing member 101, and is, for example, about 0.5 mm to 1 mm.

  Note that the shape and size of the housing member 103 may be changed as appropriate. Further, the shape and size of the accommodation space may be appropriately changed as long as the electromagnetic wave suppressing member 101 can be accommodated.

(how to use)
The electromagnetic wave suppression body 100 having the configuration described so far can attach the lower surface of the second double-sided sheet 104a to an attachment target to which the electromagnetic wave suppression body 100 is attached after the attachment separator 105a is peeled off. As an example of the attachment target, an electromagnetic component such as an electronic component, wiring, or electronic device, and a casing located in the vicinity of the electromagnetic wave generation source can be given.

  Thus, the electromagnetic wave suppression body 100 can be easily attached to the attachment target by including the second double-sided sheet 104a. And the electromagnetic wave suppression body 100 suppresses the electromagnetic waves which generate | occur | produce from the attachment target stuck by the 2nd double-sided sheet 104a. Moreover, the electromagnetic wave suppression body 100 absorbs the electromagnetic waves generated from the electromagnetic wave generation source by being attached to the vicinity of the electromagnetic wave generation source by the second adhesive sheet 104a. Thereby, it can reduce that the electromagnetic waves which generate | occur | produce from an electromagnetic wave generation source affect other electronic components, wiring, an electronic device, etc. which are arrange | positioned around the attachment object.

  Note that a single-sided adhesive sheet may be attached to the electromagnetic wave suppressing body 100 in place of the second double-sided sheet 104a. In this case, the electromagnetic wave suppression body 100 is preferably attached to an attachment target with an adhesive or the like.

  In the electromagnetic wave suppression body 100 according to the present exemplary embodiment, as described above, the upper and lower openings of the storage member 103 are closed by the sealing sheet 106a and the second double-sided sheet 104a, and the electromagnetic wave suppression member 101 is stored. It is sealed in the member 103.

  Therefore, even if the soft magnetic powder spills from the side surface or the main surface of the electromagnetic wave suppressing member 101, it hardly scatters. Therefore, it is possible to almost eliminate the operation failure of the attachment target due to the soft magnetic powder spilled from the electromagnetic wave suppressing member 101.

  Moreover, since a general adhesive sheet has flexibility, the 1st double-sided sheet 102a, the 2nd double-sided sheet 104a, and the sealing sheet 106a usually have flexibility. In addition to this, in the present embodiment, the electromagnetic wave suppressing member 101 and the housing member 103 also have flexibility. Thereby, it can attach easily to the curved surface of the attachment object which has a curved surface, and can suppress the electromagnetic waves which generate | occur | produce from an attachment object.

  At this time, the electromagnetic wave suppressing body 100 can be attached to the curved surface to be attached in a state where the electromagnetic wave suppressing member 101 is sealed. Therefore, even when the electromagnetic wave suppression body 100 is attached to the curved surface to be attached, it is possible to eliminate almost all the malfunctions of the attachment object due to the soft magnetic powder spilled from the electromagnetic wave suppression member 101.

  Furthermore, in the electromagnetic wave suppression body 100 according to the present exemplary embodiment, the thickness of the housing member 103 is the same as the height of the electromagnetic wave suppression member 101 to which the first double-sided sheet 102a is attached. Therefore, the second double-sided sheet 104 a can be attached to the first double-sided sheet 102 a and the lower end of the frame-like member 103 with almost no step. Further, the sealing sheet 106 a can be attached to the electromagnetic wave suppressing member 101 and the upper end of the frame-like member 103 with almost no step.

  As a result, the electromagnetic wave suppression member 101 is more tightly sealed than when there is a step between the first double-sided sheet 102a and the lower end of the frame-like member 103, or between the electromagnetic wave suppression member 101 and the upper end of the frame-like member 103. Can be stopped. Therefore, it is possible to more reliably eliminate the operation failure of the attachment target due to the soft magnetic powder spilled from the electromagnetic wave suppressing member 101.

  So far, the structure of the electromagnetic wave suppression body 100 which concerns on Embodiment 1 of this invention, and its usage method were demonstrated. From here, the manufacturing method of the electromagnetic wave suppression body which concerns on this Embodiment is demonstrated.

  As shown in FIG. 2, the manufacturing separator 111 is peeled off from the one manufactured in step S104 (step S105; separator peeling step). That is, the manufacturing separator 111 is peeled off from each of the first double-sided sheets 102b individualized in step S103.

  FIG. 9 is a cross-sectional view in a plane parallel to the top, bottom, left, and right when the manufacturing separator 111 is peeled off in step S105, as viewed from the front.

  As shown in FIG. 2, the large-sized second double-sided sheet 104b shown in the front view of FIG. 10 is attached to the one produced in step S105 (step S106; second attaching step). A large attachment separator 105b is attached to the lower surface of the second lower adhesive layer 108f included in the second double-sided sheet 104b attached in step S106.

  Unlike the second double-sided sheet 104a that constitutes the above-described electromagnetic wave suppressing body 100, the large-sized second double-sided sheet 104b is not individualized in association with the housing member 103. They have approximately the same shape and size.

  Except for the difference in shape and size as viewed from above, the large second double-sided sheet 104b has the same configuration as the second double-sided sheet 104a constituting the electromagnetic wave suppressing body 100, as shown in FIG. That is, the second double-sided sheet 104b is configured in the same manner except that the second base material 108a, the second upper adhesive layer 108b, and the second lower adhesive layer 108c are different in shape and size. 108d, the 2nd upper adhesion layer 108e, and the 2nd lower adhesion layer 108f.

  The large-sized mounting separator 105b has substantially the same shape and size as the large-sized second double-sided sheet 104b as viewed from above, and is attached to the second lower adhesive layer 108f as shown in FIG. Yes. Except for the difference in shape and size as seen from above, the large mounting separator 105b has the same configuration as the mounting separator 105a.

  In the second pasting step (step S106), as shown in detail in the cross-sectional view of FIG. 11, the upper surface of the second upper adhesive layer 108e is pasted on the lower surface of each of the housing members 103 arranged in step S104a.

  Each of the accommodation members 103 according to the present embodiment is formed with an accommodation space having a size capable of surrounding the side periphery of the electromagnetic wave suppression member 101 with a gap. For this reason, when the housing member 103 is arranged, a larger positional shift is allowed than when the housing member 103 is closely attached to the outer periphery of the electromagnetic wave suppressing member 101 without a gap. Therefore, since high accuracy is not required when arranging the housing member 103, more efficient production is possible.

  Since the electromagnetic wave suppression member 101 according to the present embodiment has flexibility, it hardly breaks even if the electromagnetic wave suppression body 100 is bent. Therefore, even if there is a gap between the electromagnetic wave suppressing member 101 and the housing member 103, the cracked portions are hardly magnetically separated and the magnetic permeability characteristics are hardly deteriorated. Therefore, even if the above-mentioned gap is vacant, electromagnetic waves can be sufficiently suppressed.

  The manufacturing method of the electromagnetic wave suppression body which concerns on this Embodiment includes a sealing sheet sticking process (step S104). Thereby, as above-mentioned, the relative position of the some accommodating member 103 and the some electromagnetic wave suppression member 101 is fixed. Therefore, the several electromagnetic wave suppression body 100 provided with the sealing sheet 106a can be manufactured collectively easily. Therefore, efficient production can be easily performed.

At this time, the plurality of housing members 103 are arranged so as to surround the side periphery of the plurality of electromagnetic wave suppressing members 101, respectively.

  Thereby, the upper surface of the several electromagnetic wave suppression member 101 on the manufacturing separator 111 is affixed on the large-sized sealing sheet 106b. Therefore, the relative positions of the plurality of housing members 103 and the plurality of electromagnetic wave suppressing members 101 are fixed.

  With respect to the second double-sided sheet 104 a according to this modification, the lower surface of the second lower adhesive layer 108 c is attached to the upper surface of the electromagnetic wave suppressing member 101 and the upper end of the housing member 103. In this modification, the second double-sided sheet 104a that is a double-sided pressure-sensitive adhesive sheet corresponds to the third pressure-sensitive adhesive sheet.

  In this modification, the attachment separator 105a is attached to the upper surface of the second upper adhesive layer 108b.

  As shown in FIG. 16, the manufacturing method of the electromagnetic wave suppression body according to this modification includes a second pasting step (step S304) instead of the sealing sheet pasting step (step S104) according to the first embodiment. Moreover, the manufacturing method of the electromagnetic wave suppression body which concerns on this modification includes the sealing sheet sticking process (step S306) instead of the 2nd sticking process (step S106) which concerns on Embodiment 1. FIG.

  Except for these points, the method for manufacturing an electromagnetic wave suppressor according to this modification is the same as the method for manufacturing an electromagnetic wave suppressor according to Embodiment 1.

  Specifically, after steps S101 to S103 similar to those in the first embodiment are performed, a second pasting step (step S304) is performed.

  In the second sticking step (step S304) according to the present modification, the housing member 103 disposed so as to surround each of the plurality of electromagnetic wave suppressing members 101 in the one produced in step S103 is a large second side. It is sandwiched between the sheet 104b and the manufacturing separator 111. At this time, the plurality of housing members 103 are in a state of being attached to the large second double-sided sheet 104b.

  Specifically, as shown in FIG. 16, the second sticking step (step S304) includes an arrangement step (step S104a) similar to that of the first embodiment, and fixing and fixing different from those of the first embodiment (step S304b). Including.

  In the fixing and fixing according to this modification (step S304b), the lower surface of the second lower adhesive layer 108f is attached to the upper ends of the plurality of housing members 103 and the upper surfaces of the plurality of electromagnetic wave suppressing members 101. Further, a large attachment separator 105b is attached to the upper surface of the second upper adhesive layer 108e.

  Thereafter, after the manufacturing separator 111 is peeled off in step S105, a sealing sheet attaching step (step S306) is performed.

  In the sealing sheet sticking process (step S306) according to the present modification, the large sealing sheet 106b is attached to the one prepared in step S105. Specifically, the upper surface of the third adhesive layer 109d is attached to the lower end of each of the housing members 103 and the lower surface of the first lower adhesive layer 107c included in each of the individual first double-sided sheets 102a.

  Then, what was produced in step S306 is individualized by the electromagnetic wave suppression body 300 by the method similar to Embodiment 1 (step S107; individualization process).

  Also according to this modification, the same effects as those of the first embodiment are obtained.

<< Modification 3 >>
In Embodiment 1, the sealing sheet 106a of the electromagnetic wave suppressing body 100 may not be provided.

  However, in this modified example, after the separator peeling step (step S105), there is a possibility that the housing member 103 and the electromagnetic wave suppressing member 101 to which the first double-sided sheet 102a is attached are separated separately. In order to prevent this, the relative positional relationship between the electromagnetic wave suppressing member 101 to which the plurality of housing members 103 and the first double-sided sheet 102a are attached is fixed by an appropriate method before the separator peeling step (step S105). Also good.

  For this fixing, for example, a temporary fixing sheet instead of the sealing sheet 106a may be employed. The temporary fixing sheet only needs to have a relatively weak adhesive force and can be easily attached and detached. And it is good to remove a temporary fix | stop sheet | seat after a 2nd sticking process (step S106).

  Also in this modification, a plurality of electromagnetic wave suppression bodies 100 can be manufactured together. Therefore, efficient production becomes possible.

  Also in this modified example, the lower opening of the housing member 103 is closed by the second double-sided sheet 104a. Therefore, even if the soft magnetic powder spills from the side surface or the main surface of the electromagnetic wave suppressing member 101, the possibility that the soft magnetic powder is scattered from below the housing member 103 is reduced. Accordingly, it is possible to reduce malfunctions of electronic components, wiring, electronic devices, and the like caused by the soft magnetic powder spilled from the electromagnetic wave suppressing member 101.

  In the present embodiment, unlike the first embodiment, it is not necessary to arrange the plurality of accommodating members 103 at intervals, so that the intervals between the plurality of electromagnetic wave suppressing members 101 can be reduced. For this reason, the surplus portion 112 can be reduced, and the production cost can be reduced. Except for this point, the half-cut process (step S402) is the same as the half-cut process (step S102) according to the first embodiment.

  As shown in FIG. 17, a surplus removal step (step S103) similar to that in the first embodiment is performed. The result of performing Step S103 in the present embodiment is shown in the front view of FIG.

  In the present embodiment, the accommodation sheet 413 is a lattice-shaped member having a main surface parallel to the front-rear direction and the left-right direction. In the storage sheet 413, a plurality of rectangular storage spaces as viewed from above are formed side by side in the front-rear and left-right directions.

  Specifically, each of the plurality of storage spaces formed in the storage sheet 413 has a space and a size capable of storing the plurality of electromagnetic wave suppression members 101 produced in step S103 with a gap around the side. Is provided.

  The number, size, shape, arrangement, etc. of the accommodation spaces formed in the accommodation sheet 413 are the same as the number, size, shape, arrangement, etc. of the electromagnetic wave suppression members 101 separated from the electromagnetic wave suppression sheet 110 in step S402. Accordingly, it may be changed as appropriate.

  In detail, as shown in FIG. 17, the sealing sheet sticking process (step S404) includes an arrangement process (step S404a) and fixing (step S404b).

  In the arrangement step (step S404a), the accommodation sheet 413 is arranged on the manufacturing separator 111 of the one produced in step S103, as shown in FIG. FIG. 21 is a cross-sectional view of a state in which the storage sheet 413 is disposed in step S404a on a plane parallel to the top, bottom, left, and right when viewed from the front.

Thereby, as shown in FIG. 22, the opening above the accommodation sheet 413 is closed. FIG. 22 is a cross-sectional view of a state in which the large sealing sheet 106b is attached to the storage sheet 413 and the plurality of electromagnetic wave suppressing members 101, in a plane parallel to the top, bottom, left, and right when viewed from the front.

  As shown in FIG. 17, the manufacturing separator 111 is peeled from the one manufactured in step S404 (step S405; separator peeling step). FIG. 23 is a cross-sectional view in a plane parallel to the top, bottom, left, and right when the manufacturing separator 111 is peeled off in step S405 as viewed from the front.

  As shown in FIG. 17, the large-sized second double-sided sheet 104b is attached to the one produced in step S405 (step S406; second attaching step). As shown in FIG. 24, the large-sized second double-sided sheet 104b is provided with a large-sized mounting separator 105b. FIG. 24 is a cross-sectional view of a state in which the large second double-sided sheet 104b is attached in step S406 on a plane parallel to the top, bottom, left, and right when viewed from the front.

The cutting line CL is set between the outer edge viewed from above the accommodation sheet 413 and between each of the plurality of accommodation spaces.

  When the sealing sheet 106b, the storage sheet 413, the second double-sided sheet 104b, and the mounting separator 105b are aligned with the outer edge of the storage sheet 413 when viewed from above, the cutting line CL along the outer edge of the storage sheet 413 Is unnecessary.

  In the accommodation sheet 413 according to the present embodiment, an accommodation space having a size capable of surrounding the side periphery of the electromagnetic wave suppression member 101 with a gap is formed as in the first embodiment. Therefore, when the accommodation sheet 413 is arranged, a larger positional deviation is allowed than when the accommodation sheet 413 is closely attached to the outer periphery of the electromagnetic wave suppressing member 101 without a gap. Therefore, since high accuracy is not required when arranging the accommodation sheet 413, more efficient production becomes possible.

  Also in the present embodiment, the electromagnetic wave suppressing member 101 has flexibility. Therefore, similarly to Embodiment 1, even if the above-mentioned gap is vacant, electromagnetic waves can be sufficiently suppressed.

  The manufacturing method of the electromagnetic wave suppression body which concerns on this Embodiment includes a sealing sheet sticking process (step S404). Thereby, the relative position of the accommodation sheet 413 and the plurality of electromagnetic wave suppressing members 101 is fixed. Therefore, the several electromagnetic wave suppression body 100 provided with the sealing sheet 106a can be manufactured collectively easily. Therefore, efficient production can be easily performed.

  In the manufacturing method of the electromagnetic wave suppression body according to the present embodiment, the accommodation sheet 413 is disposed in step S404a. Therefore, it is not necessary to arrange the plurality of housing members 103 individually. Therefore, more efficient production becomes possible.

  As shown in FIG. 28, the electromagnetic wave suppression body 600 includes an electromagnetic wave suppression member 101, a first double-sided sheet 102a, a second double-sided sheet 104a, and a mounting separator 105a similar to those in the first embodiment. Since these members 101, 102a, 104a, and 105a are the same as those in the first embodiment, the description in the present embodiment is omitted.

  Further, the electromagnetic wave suppressing body 600 includes a housing member 603 different from that in the first embodiment.

  The housing member 603 is a substantially rectangular member as viewed from above, and has an upper surface and a lower surface which are main surfaces parallel to each other. The housing member 603 is made of, for example, resin or rubber and has flexibility.

  The housing member 603 includes a substantially rectangular parallelepiped recess extending upward from an opening formed in the lower surface. This dent corresponds to an accommodation space in which the electromagnetic wave suppressing member 101 to which the first double-sided sheet 102a is attached is accommodated.

  The height of the recess included in the housing member 603 according to the present embodiment is the same as the height of the electromagnetic wave suppressing member 101 to which the first double-sided sheet 102a is attached. For this reason, the upper surface of the electromagnetic wave suppressing member 101 is generally in contact with the inner upper surface forming the recess of the housing member 603. Here, the height of the dent means the length of the dent in the vertical direction, and the same applies to the following.

  Further, in the housing member 603 according to the present embodiment, as shown in FIG. 28B, the side periphery is surrounded with a gap. This gap is an interval in the front-rear direction or the left-right direction between the inner side surface forming the depression of the housing member 603 and the outer edge of the electromagnetic wave suppressing member 101, and is, for example, about 0.5 mm to 1 mm, but is appropriately changed. May be.

  Note that the shape and size of the housing member 603 may be changed as appropriate. Further, the shape and size of the recess may be appropriately changed as long as the electromagnetic wave suppressing member 101 can be accommodated.

(how to use)
Similarly to the electromagnetic wave suppressing body 100 according to the first embodiment, the electromagnetic wave suppressing body 600 having the configuration described so far can peel the mounting separator 105a and then attach the second double-sided sheet 104a to the mounting target. . Thereby, the electromagnetic wave suppression body 600 is easily attached to the attachment target, and suppresses electromagnetic waves generated from the attachment target attached by the second double-sided sheet 104a.

  Note that a single-sided adhesive sheet may be attached to the electromagnetic wave suppressing body 600 in place of the second double-sided sheet 104a. In this case, the electromagnetic wave suppression body 600 is preferably attached to an attachment target with an adhesive or the like.

  In the electromagnetic wave suppression body 600 according to the present exemplary embodiment, the second double-sided sheet 104 a is attached to the lower end of the housing member 603. As a result, the opening below the housing member 603 is closed, and the electromagnetic wave suppressing member 101 is sealed in the housing member 603.

  Therefore, similarly to the electromagnetic wave suppressing body 100 according to the first embodiment, it is possible to almost eliminate the operation failure of the attachment target due to the soft magnetic powder spilled from the electromagnetic wave suppressing member 101.

  Further, the electromagnetic wave suppressing member 101 and the housing member 603 according to the present embodiment have flexibility. Thereby, similarly to the electromagnetic wave suppression body 100 according to Embodiment 1, it is possible to easily attach to the curved surface of the attachment target having a curved surface and suppress the electromagnetic wave generated from the attachment target.

  At this time, the electromagnetic wave suppressing body 600 can be attached to the curved surface to be attached in a state where the electromagnetic wave suppressing member 101 is sealed. Therefore, even when the electromagnetic wave suppression body 600 is attached to the curved surface to be attached, it is possible to eliminate almost any operation failure of the attachment object due to the soft magnetic material powder spilled from the electromagnetic wave suppression member 101.

Furthermore, in the electromagnetic wave suppression body 600 according to the present exemplary embodiment, the height of the recess is the same as the height of the electromagnetic wave suppression member 101 to which the first double-sided sheet 102a is attached. Therefore, the second double-sided sheet 104 a can be attached to the first double-sided sheet 102 a and the lower end of the frame-like member 103 with almost no step.
Thereby, the electromagnetic wave suppressing member 101 can be sealed more firmly than when there is a step between the first double-sided sheet 102 a and the lower end of the frame-like member 103. Therefore, it is possible to more reliably eliminate the operation failure of the attachment target due to the soft magnetic powder spilled from the electromagnetic wave suppressing member 101.

  So far, the configuration of electromagnetic wave suppression body 600 according to Embodiment 3 of the present invention and the method of using the same have been described. From here, the manufacturing method of the electromagnetic wave suppression body 600 which concerns on this Embodiment is demonstrated.
