Description of the invention (1) Background of the invention The present invention relates to a deflection yoke, which is suitable for use in a thin-neck cathode ray tube. The cathode ray tube It has characteristics of large or wide deflection angle, and a cathode ray tube device and a display device using the deflection yoke, and in particular, it is a countermeasure against magnetic field leakage caused by unnecessary magnetic field radiation from the deflection yoke. There is an urgent need to reduce the unnecessary magnetic field radiation generated around the cathode ray tube device to a fixed chirp. In particular, in terms of unnecessary radiation in a low frequency band of less than 4 〇 Κ Η Z, there is already a guidance benchmark called TCO (The Swedish Confederation Employees). This guideline determines that when measuring from a point of 50 cm around the display device and from a distance of 30 cm from the tube surface of the cathode ray tube device, ELMF (ultra-low frequency magnetic field) from 5 Hz to 2 KHz must be VLMF (very low frequency magnetic field) equal to or lower than 2000nT and from 2KHz to 400KHz must be equal to or lower than 2 5 η T. Since the main source of E LMF and VLMF is biased yoke, various countermeasures have been proposed to generate a magnetic field of opposite polarity to offset unnecessary magnetic field radiation, thereby reducing unnecessary magnetic field radiation to make it equal to or lower than the standard value. One representative example is Japanese Patent No. 3_289029 (1991), which discloses a reducing device for unnecessary magnetic field radiation. In this device, the cancellation coil is connected to the horizontal deflection coil and the vertical deflection coil, respectively. A magnetic field is newly generated to cancel the unnecessary magnetic field radiation generated by the horizontal and vertical deflection lines respectively, thereby reducing unnecessary magnetic field radiation. This paper size applies to China National Standard (CNS) A4 specification (210 X 297 mm) ~ 7 ~ _ ----------- <, installed -------- order ---- ----- Line Ίϋ- (Please read the notes on the back before filling this page) 4 819 4 A? _____B7______ V. Description of the invention (2) (Please read the notes on the back before filling this page) Japanese Patent No. Hei 3-165427 (1991) discloses that the size of the coil biased to the yoke is designed or managed without using an offset coil to reduce unnecessary magnetic field radiation. Summary of the Invention However, according to Japanese Patent No. Hei 3-289029 (199.1), when the unnecessary magnetic field radiation is reduced, important characteristics of the bias yoke are significantly damaged, such as horizontal bias sensitivity and vertical bias sensitivity. In addition, as for the offset line, the size and weight of the bias yoke in the external shape will increase. Therefore, it will not only increase the manufacturing cost of the bias yoke, but also damage and cause the manufacture of the cathode ray tube to be difficult to exceed that in the cathode ray. Limitation of the mechanical strength of the neck of the tube. At the same time, according to a conventional technique such as disclosed in Japanese Patent No. Hei. 3-16 5 4 2 7 (19 9 1), a plan for forming has been disclosed, that is, a magnetic core is formed in the axial direction, and its core The length is 40% to 60% of the distance between the front end and the rear end of the bridge part constituting the horizontal deflection coil, so as to suppress the damage in the characteristics of the deflection yoke. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. However, for the current need for a cathode ray tube and / or cathode ray tube device with a wide display screen, a thin thickness, and low power consumption losses, the above-mentioned conventional technology does not consider the cathode The neck diameter of the ray tube does not take into account the shape of the magnetic core, which needs to be used to achieve the purpose of reducing unnecessary magnetic field radiation, while satisfying the basic deflection characteristics of the cathode ray tube. That is, the cathode ray emitted by the electron gun reaches the phosphor screen, and is then deflected by a magnetic field formed by a deflection yoke. In this example, the magnetic field deflected by the deflection yoke must be strengthened to expand the paper size to apply the Chinese National Standard (CNS) A4 (210 X 297 mm) -5- 4 6 81 9 4 A7 B7 employees of the Intellectual Property Bureau of the Ministry of Economic Affairs Printed by the Consumer Cooperative V. Invention Description (3) Large deflection angle, but this result will not only increase the energy loss from the deflection yoke, but also increase the shape and size of the deflection yoke and its manufacturing cost. In order to solve the problems of the above-mentioned conventional techniques, by thinning the neck of the cathode ray tube attached to the yoke, the wide-angle and small magnetic field density can be biased toward the cathode ray. On the other hand, the thinner the neck, the lower the mechanical strength. This will also cause a serious problem. Therefore, it is necessary to reduce the weight of the magnetic core, which occupies about 50% of the weight of the biased yoke attached to the neck, in order to design the size of the biased yoke to improve its characteristics and prevent the characteristics from being damaged. In order to solve the above problems, it is an object of the present invention to provide a deflection yoke which can be applied to a thin neck cathode ray tube showing a wide deflection angle characteristic, a cathode ray tube using the deflection yoke, and a display.

Description of Invention (9). Here, the neck diameter is measured on the part of the cathode ray tube with an electron gun (collective) attached, and when measured with a known measuring device such as a vernier caliper, micrometer, etc., the display is almost equal Of its diameter. Furthermore, in general, when the angle from a bias to the center, that is, the tapered portion of the cathode ray tube is concentrated at a point by extrapolation, when viewed into a phosphor screen, the deflection angle is defined as being formed on the phosphor screen The upper diagonal effectively shows the corners between the surfaces. The magnetic core 4 described above has a circular inner surface, and the thickness ratio formed is at least approximately equal to 1 or less than the level at which the three electron guns of red (R), green (G), and blue (B) are arranged on a straight line. The thickness in the vertical direction. When a magnetic core having this cross section is applied to a deflection yoke, the deflection magnetic field is formed by a horizontal deflection coil 2 and a vertical deflection coil 3 in a neck of a cathode ray tube through which a cathode ray from an electron gun passes, which is in a vertical direction. Quite weak and quite strong in the horizontal direction. However, since the core thickness is relatively large in the horizontal direction, the generated magnetic field does not saturate with respect to the coil current, so a magnetic field with sufficient strength can be maintained. Furthermore, by this, not only the geometric distortion and non-convergence, but also the damage caused by the temperature rise in the magnetic core 4 can be automatically compensated. Furthermore, in the case where the core core 4 has a uniform core thickness, among the parts constituting the bias yoke 1, the cathode ray tube is easily broken at the neck because it accounts for about 50% of the weight of the bias yoke. However, according to the present invention, by making the core thickness of the magnetic core 4 thinner in the vertical direction than in the horizontal quotient, the weight can be reduced by about 20%. Therefore, not only the weight reduction biased to the vehicle itself can be achieved, but also Prevent the cathode ray tube from rupturing in the neck. Here, the paper size of the magnetic core 4 of the magnetic core 4 in the vertical direction and the horizontal direction applies to the Chinese National Standard (CNS) A4 specification (210 X 297 mm> _ i2-(Please read the note on the back before filling out (This page) Earthquake ----! | Order --------- line A7 46 81 94 B7___ V. Description of the invention (10) The ratio of the thickness of the core is at least about 1, and preferably less than 1, and equal to Or greater than 0.7. The reason is that if the core ratio is equal to or greater than 0.7, the magnetic core 4 itself can obtain sufficient mechanical strength during the manufacturing process, so it can be manufactured by the casting method widely used today, and The productivity will not be reduced. Furthermore, as shown in FIG. 2, the biasing yoke 1 on which the above-mentioned magnetic core 4 is mounted is attached to the wall surface 1 of the cathode ray tube 1. In this way, the biasing yoke 1 is biased The weight itself is supported by the wall surface of the cathode ray tube as much as possible, so as to prevent the neck from rupturing. Furthermore, the biasing yoke 1 also uses the fastening tape 22 to fix the neck of the cathode ray tube. In addition, it is also used to prevent the movement to the yoke 1. However, the yoke 1 is intended to be attached and used. The neck diameter and deflection angle of the polar tube should not be limited to the above-mentioned areas. That is, the deflection angle is preferably from 95 ° to 110 °, and more preferably from 97 ° to 105 °. The reason is that when a deflection yoke is used, it is the same as a cathode ray tube attached to a cathode ray tube having the above-mentioned deflection angle characteristics such as 90 ° to 115 °, and the magnetic field required to deflect at a desired angle can be reduced and maintained. The same biasing characteristics as described above, that is, a reduction in electric energy loss from the biasing yoke 1 itself can be obtained, or a circuit that drives the biasing yoke 1 can be further achieved by a relatively simple circuit configuration compared to the above example, or a small capacitor such as The transistor component structure significantly reduces the overall cost of the control system including the yoke 1. Furthermore, the neck diameter of the cathode ray tube to which the yoke 1 is attached should not be limited to the above-mentioned 値, for example, equal to or larger than 0 1 8 mm and equal to or smaller (please read the precautions on the back before filling out this page) ------------ Order --------- · Consumer Consumption Cooperative of Intellectual Property Bureau, Ministry of Economic Affairs Printed paper standards are applicable to Chinese national standards ( CNS) A4 specification (210 X 297 mm) -13- A7 46 81 9 4 B7 V. Description of the invention (11) is divided into 2 6mm. Preferably, it is required that the neck diameter is equal to or greater than 2 2mm And equal to or less than 0 2 6 mm, and more preferably equal to or greater than 2 4 mm and equal to or less than 〆 2 5 mm. When the same bias yoke 1 is attached to the neck of the cathode ray tube to be used, the reason may be between The relationship between the diameter of the neck and the resolution, which is one of the performances of the cathode ray tube, and the power loss between the deflection circuits including the deflection yoke will be explained, as shown in Figure 3 = In Figure 3, vertical The axis represents the resolution and electrical energy loss with a relative chirp. The larger the diameter of the neck, the easier the electron beam can focus on the phosphor screen of the cathode-ray tube, thus achieving high-resolution display. On the contrary, the energy consumption loss of the bias yoke 1 increases. Therefore, it may not only be unable to meet the demand for the low energy loss of the bias yoke, but it may also reduce the efficiency of the bias yoke. At worst, when the energy loss The increased heat will soften the parts that make up the yoke 1, such as a plastic resin frame. In particular, when the diameter of the neck exceeds 0 2 6 mm, the power consumption loss shows a steep increase. At the same time, if the neck is equal to or smaller than 18 mm, this relationship will be sharply reduced. The diameter of the neck is equal to or greater than 018 mm and equal to or less than 〆2 6 mm is a range required to satisfy at least two characteristics, that is, the energy loss and resolution of the yoke in various performances of the cathode ray tube, and more particularly , It must be equal to or greater than 0 2 2 mm and equal to or less than 0 2 6 mm, and most specifically, it must be equal to or greater than 2 4 mm and equal to or less than 0 2 5 mm in order to comply with the resolution and energy consumption. Of any characteristics. Next, the dimensions of various parts constituting the deflection yoke 1 will be described. By adopting (please read the precautions on the back before filling this page) / wai i I!-Order -------- line, printed by the Intellectual Property Bureau of the Ministry of Economic Affairs, Consumer Cooperatives, this paper is applicable to China Standard (CNS) A4 specification (210 X 297 mm) -14- 4 6 81 9 4- A7 B7 V. Description of the invention (12) (Please read the note on the back before filling this page) Use a representative example Describe a deflection yoke attached to a cathode ray tube, the neck diameter of which is equal to or greater than 0 2 4 mm and equal to or less than 2 5 mm, and the deflection angle is equal to or greater than 97 ° and equal to or less than 105 ° ° Printed by a member of the Intellectual Property Bureau of the Ministry of Economic Affairs and the Consumer Cooperative, Figure 4 shows the dimensions of the yoke 1 in the tube axis direction, which is used when the neck diameter is equal to or greater than · 0 2 4mm and equal to or less than 2 5mm, and the deflection angle is A cathode ray tube of 97 ° or more and 105 ° or less. The deflection yoke 1 of this embodiment includes a horizontal deflection coil 2, a vertical deflection line 圏 3, and the magnetic core 4 shown in FIG. 1. The length of the horizontal deflection coil 2 in the tube axis direction is a, and the vertical deflection coil 3. The length in the tube axis direction is b, the length of the magnetic core 4 in the tube axis direction is c, the distance between the horizontal side of the open side end of the coil 2 and the open side end of the core 4 is d, and the vertical The distance between the opening-side end of the bias coil 3 and the opening-side end of the core 4 is e. However, the dimensions of the horizontal deflection line 圏 2, the vertical deflection coil 3, and the magnetic core 4 are between the coil and the core of the core when measured with a known measuring device, such as a vernier caliper, a micrometer, etc. The measured length between the side and the open end. Furthermore, the horizontal deflection line 圏 2 and the vertical deflection coil 3 are coils, which are wound into a saddle shape. FIG. 5 is a graph showing the change rate of the horizontal deflection sensitivity with respect to the length a in the tube axis direction of the horizontal deflection line 圏 2. As shown in the figure, when the size of the horizontal deflection coil 2 is 90 mm, the length of the deflection yoke 1 shown here is changed or shifted in the direction of the opening side and the neck side, respectively. When the dimension a of the horizontal deflection coil 2 extends only on the opening side, the horizontal deflection sensitivity increases, and the deflection characteristics tend not to be damaged. On the other hand, in the horizontal deflection line, the paper size applies the Chinese National Standard (CNS) A4 (210 X 297 mm) -15- Α7 ___ Β7__ 5. Description of the invention (13) The size a of the circle 2 extends only on the neck On the side, the horizontal deflection sensitivity is reduced, and the deflection characteristics are improved. That is, with the size of the deflection yoke 1 attached to a cathode ray tube having a wide deflection angle, for the purpose of improving the horizontal deflection sensitivity, the length of the horizontal deflection coil extends from the current position on the neck side and opens in the opening. End-to-side contraction is effective. Next, FIG. 6 is a graph showing the variation of the electron beam impingement on the neck (hereinafter referred to as B S N) with respect to the electron beam of a length a in the tube axis direction of the horizontal deflection coil 2. In the same figure, the BSN change rate indicates an example when the size of the horizontal deflection coil 2 is changed or shifted in the direction of the open side and the neck side of the yoke 1, respectively, according to the size of 9 ◦ mm, and its meaning That is, the larger this threshold is, the less the lack of display screen appears on the phosphor screen of the cathode ray tube. In the example where the dimension a of the horizontal deflection coil 2 is enlarged to the opening side, B S N 値 is increased, that is, the performance of the cathode ray tube is improved. On the other hand, in the case where the size a of the horizontal deflection coil 2 is enlarged to the neck side, B S N 値 is decreased, and therefore, the lack of a display screen can easily appear on the phosphor screen of the cathode ray tube. Therefore, in order to improve B S 1 ^ 値, it is preferable to extend from the standard position in the direction of the horizontal deviation from the dimension a of the coil 2 to the opening side, rather than in the direction of the neck side. However, from the results of Figs. 5 and 6, it can be seen that the relationship between the horizontal sensitivity indicating the effectiveness of the bias yoke 1 and B S N is inversely proportional to the size at the horizontal bias line 线 2. In order to satisfy the two deflection characteristics, when the size of the horizontal deflection coil 2 is changed, it will inevitably be changed to both the opening side and the neck side direction of the yoke 1 at the same time. However, there is a level in order to determine the size of the horizontal deflection line 且 2 and simultaneously satisfy the various characteristics of the deflection yoke 1.

Description of the invention (14) Biased coil The appropriate range of the size 2 is described below. First, the upper limit of the size of the horizontal deflection line 圏 2 in the direction of the tube axis will be described. Fig. 7 is a graph showing the relationship between the size a of the horizontal deflection coil 2 and the diameter of the electron beam on the phosphor screen of the cathode ray tube. In the same figure, "the diameter of the electron beam is expressed as 100%", and the focus failure on the display screen such as the non-focusing of the image does not occur. As a result, if the horizontal deflection coil 2 is changed to the opening side of the yoke 1, the size a thereof hardly affects the electron beam diameter. However, especially when the size a is increased in the direction of the neck side, the diameter of the electron beam rises remarkably, and thus problems such as focus destruction of the image are generated. That is, the maximum value 尺寸 of the dimension a of the horizontal deflection coil 2 is determined by the allowable focusing characteristic on the neck side and the horizontal deflection characteristic on the opening side. Therefore, from the results shown in the figure, the maximum allowable 値 of the size of the horizontal deflection coil 2 is 100 mm to meet one of the performances of the cathode ray tube, such as image resolution or resolution, and further deflection. Characteristics of sensitivity. Next, the lower limit of the dimension a of the horizontal deflection coil 2 in the tube axis direction will be described. Another method for determining the size a of the horizontal deflection line 圏 2 while maintaining the deflection sensitivity is to shorten the size a on the neck side and the wide mouth side of the deflection yoke 1 at the same time. In this example, the shape of the horizontal deflection line 圏 2 inevitably becomes smaller, so the surface of the deflection coil itself becomes smaller or narrower, and therefore, the temperature increase on the deflection line 圏 itself appears to be quite significant. Fig. 8 is a graph showing the relationship between the dimension a and the temperature increase in the deflection yoke. In the figure, the temperature is indicated according to the maximum allowable temperature of the deflection yoke 1, and it is determined for the following reasons. That is, in general, plastic mold materials are used to form the frame deviating to the yoke 1, but 'when the temperature exceeds its thermal softening temperature, its mechanical stress will be significant.

The description of the invention (15) (谙 Please read the precautions on the back before filling in this page), so it is difficult to maintain the shape of the frame itself. Furthermore, the conductors that are biased toward the wire are covered with plastic resin (eg, enamel) to fix them together. However, when the temperature exceeds the thermal resistance deformation temperature, it is not only difficult for the conductor of the coil itself to maintain its shape, but also covered The electrical insulation of the enamel layer on the conductor will also be reduced, thereby causing local corona discharge. In the case of falling into this situation, the biased yoke loses its function and causes non-convergence. Therefore, it is inevitable that the size a of the horizontal deflection coil constituting the deflection yoke 1 should be selected in a range so that it does not exceed the allowable temperature of the material of the parts used here. The results of Fig. 8 show that the dimension a of the horizontal deflection coil 2 must be equal to or greater than 80 mm in order to satisfy the allowable temperature increase relative to the temperature in the deflection yoke 1. From the above results, it can be seen that when the dimension a of the horizontal deflection coil 2 is set to be equal to or greater than 80 mm and equal to or less than 100 mm, compared to a thin neck type cathode ray tube having a wide deflection angle characteristic, its It can display good deflection characteristics without the destruction of the focused image, and it can prevent non-convergence from occurring as the temperature rises. Printed by the Intellectual Property Bureau of the Ministry of Economic Affairs 4 Consumption cooperatives Next, the dimension b in the direction of the tube axis of the vertical deflection coil 3 constituting a part of the deflection yoke 1 will be described. As shown in FIG. 4, the dimension b of the vertical deflection coil 3 in the tube axis direction is equal to the thickness of the edge on the opening side and the neck side of the horizontal deflection coil 2 by subtracting the horizontal deflection coil 2 from the horizontal deflection coil 2 and for insulating the horizontal deflection coil. 2 and vertical deviation, the size obtained by the thickness of the separator (not shown) of the coil 3. For example, in the case where the thicknesses of the edges on the open side and the neck side of the horizontal deflection coil 2 are 5 mm and 20 mm, respectively, and the paper size of the separator used for insulation is applicable to the Chinese National Standard (CNS) A4 specification ( 210 X 297 mm) -18- A7 _ B7__ V. Description of the invention (1β) When the thickness on the mouth and neck side is about 2 mm, the length of the dimension b of the vertical deflection coil 3 is shorter than that of the horizontal deflection coil 2 The size a is about 3 Omm. Therefore, when the size a of the horizontal deflection coil 2 is determined to be equal to or greater than 80 mm and equal to or less than 100 mm, it is preferable to make the size b of the vertical deflection coil 2 to be equal to or greater than 50 mm and equal to or less than 7 mm. Inside. In the same way, the size c of the magnetic core 4 in the tube axis direction is equal to the thickness b on the opening side and the neck side of the vertical deflection coil 3 by subtracting from the size b of the vertical deflection coil 3 and the insulation for insulation. The thickness obtained from the space. For example, when the thickness of the edges on the open side and the neck side of the vertical deflection coil 3 is about 5 mm to 8 mm, and generally, by making the distance between the vertical deflection line 圏 3 and the magnetic core 4 When the space for insulation is 4mm, it is better to make the size c in the tube axis of the magnetic core 4 shorter than the size b of the vertical deflection coil 3 by 2 Omm, that is, equal to or greater than about 3 ◦ mm and equal to or Less than about 50 mm. As described above, the dimensions of the horizontal deflection line 圏 2, the vertical deflection line 圏 3, and the magnetic core 4 are selected to be equal to or greater than about 8 Omm and equal to or less than about 10 Omm, equal to or greater than about 5 Omm, and equal to Or less than about 70 mm, and equal to or more than about 30 mm and equal to or less than about 50 mm, and they are used in the deflection yoke of a thin-necked cathode ray tube having a wide deflection characteristic, so that electrons emitted by an electron gun The deflection of the beam can suppress the occurrence and non-convergence of geometric distortion in the vertical direction1, that is, the destruction of the horizontal deflection sensitivity and the vertical deflection sensitivity will not occur.

The reason is that, because the upper limit of each size is limited by the resolution and sensitivity characteristics (which is the performance of the cathode ray tube), it is possible to determine the dimensions relative to the characteristics of the cathode ray tube by determining the dimensions shorter than the above. Increase the border. This not only helps to bias the yoke 1 itself, but also increases the yield and productivity of the cathode ray tube to which the bias yoke 1 is attached, and further reduces the manufacturing cost. On the other hand, the lower limit of each 値 is determined by the allowable 値 with respect to the increase in temperature with respect to the yoke 1. Therefore, by selecting these sizes to be longer than the above sizes, the increase in temperature to the yoke 1 can be suppressed, that is, obtained Reduced power consumption losses. Therefore, compared with the above-mentioned deflection yoke 1 of the above-mentioned size, it is possible to form a simpler circuit for driving the deflection yoke 1, or to make the parts used here, such as the capacitance of a transistor, smaller, to help reduce the cost. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. As shown in Figure 4, when the horizontal deflection line 圏 2, the vertical deflection coil 3, and the magnetic core 4 which constitute the deflection yoke 1 are assembled, the subsequent devices must be related to The relationship of the relevant positions of each part is formed. That is, every distance, such as the distance between the open side end of the magnetic core 4 and the open side end of the horizontal deflection coil 2 and the open side end of the magnetic core 4 and the vertical deflection line 圏 3 The distance d between the open side ends is determined to be at least greater than the distance on the neck side and as large as possible. And for the horizontal deflection coil 2, the vertical deflection line 圏 3, and the magnetic core 4, it must be attached to the neck of the cathode ray tube and maintain this positional relationship.

From this result, it can be known that the longer the distance d, the lower the V L M F is, that is, in other words, by setting the magnetic core 4 as far away as possible from the phosphor screen of the cathode ray tube, VLMF can be reduced. Therefore, 'Although the positional relationship of the components constituting the deflection yoke 1 is shown in FIG. 10, in order to satisfy the standard for VLMF (equal to or less than 2 5 ηT)', it is necessary to determine the opening side end and the horizontal deflection between the magnetic core 4 The distance d between the open side ends of the coil 2 is equal to or less than 15 mm »As mentioned earlier, the configuration and size of the deflection yoke 1 used in the cathode ray tube 'its neck diameter is equal to or greater than 0 2 4 mm and equal to Or less than 0 2 5mm, and the deflection angle is equal to or greater than 97 ° and equal to or less than 105 °, that is, the size a of the horizontal deflection line ，, the size b of the vertical deflection line 圏, and the size c of the magnetic core Equal to or greater than about 80 mm and equal to or less than about 100 mm, equal to or greater than about 50 mm and equal to or less than about 70 mm, and equal to or greater than about 30 mm and equal to or less than about 50 mm, further compared The best are equal to or greater than about 90 mm and equal to or less than about 9 5 m, equal to or greater than about 6 ◦ mm and equal to or less than about 6 5 mm, and equal to or greater than about 4 mm and equal to or less than about 4 5 mm, Among them, the open side end of the magnetic core 4 and the horizontal bias to the coil 2 The side ends of the opening are separated by a distance equal to or greater than 15 mm to obtain the essential characteristics of the bias yoke 1, without using the offset line widely used in conventional techniques, and to reduce the cost caused by the bias yoke 1.

Figure 11 shows the relationship between the distance e defined between the open side end of the magnetic core 4 and the open side end of the vertical deflection line 圏 3 and the change rate of E L M F generated by the deflection yoke 1. From this result, it can be seen that the longer the distance e, the lower the ELMF 値, that is, in other words, by setting the magnetic core 4 as far away as possible from the open side end of the vertical deflection coil, the ELMF 降低 can be reduced. Therefore, although the positional relationship of the parts constituting the deflection yoke 1 is shown in FIG. 12, in order to meet the standard 値 (equal to or less than 200 nT) for E LMF, it is necessary to decide between the open side end of the magnetic core 4 and the vertical The distance e between the open side ends of the deflection coils 3 is equal to or greater than 5 mm.
