In this example, the patch 30 is close to the blue gun wind to offset the difference, as shown in Figure 4 (B). In Figure 4 (C), the blue beam is inside the red beam, and then the 'compensation sheet' Position 30 is on the side close to the red gun, as shown in FIG. 4 (D). The displacement amount of the beam position is controlled by moving the compensator 30, as shown by arrows F 1 〇 and F 1 2. As described in the soil, the compensation device pair: 2 0 and 2 0 / requires a configuration to slide the compensation sheet 30 along the diameter direction of the separator pair 10 and 12 and keep the compensation sheet 30 in any desired position . In the conventional method, the pair of shaped ribs 2 2 and 2 4 are parallel to the diameter direction of the separator pair 10 and 12 to slide the compensating sheet 30. • The pair of shaped ribs 2d and 24 and the semi-cylindrical form a rib 2 The pair of 6 and 2 8 are formed separately to properly hold the compensation sheet 30 so as to have small spaces 22A and 24A (FIG. 3). The circular column forms the length ratio of the pair of ribs 26, 28 and the length moment of the pair of ribs 22, 24, so that a molding die closed to the separators 10, 12 can be produced. This type of compensation device is disclosed in Japanese Patent Application No. 63-44364 / 1988 and Japanese Patent Application No. 63-44364 / 1988 and the paper size of this compensation device is applicable to China National Standard (CNS) Λ4 wash grid (210X297mm) .

In addition to the width of the compensating piece 30 in the moving direction, the ribs 22 and 24 must have the length of the sliding range of the compensating piece 30. Since the molds used to produce the separators 10 and 12 need to have thin, long and narrow shapes at the positions of the ribs 2 2 and 24, and particularly at the protruding portions 2 2 B and 2 4 B of the ribs 2 2 and 2 4 In terms of position,] [fc molds are mechanically weak and difficult to manufacture. 9 Due to the thin, long and narrow shape of the mold, the ribs 22 and 24 are easily deformed and difficult to manufacture. When the compensating sheet 30 is forced into a narrow groove between the ribs 2 2 and 24, it will be difficult to perform manual operation of the compensating sheet 30. Since the insertion direction of the catcher 30 is restricted, the design of the yoke is also restricted. Since the materials of the separators 10, 12 are usually made of plastic with poor dimensional accuracy, it is difficult to design and control the production of the separators 10, 12. In Fig. 5 (B), the 'L " shaped ribs 22 and "24" gradually decrease in width in the cross-sectional direction, that is, 01 and 02 in the figure. As a result, a larger gap than the designer produces, and then, it becomes difficult to adjust the compensation sheet 30 at the desired position. Among the deflection yokes produced, as mentioned earlier, reference circle 4, each deflection yoke is pre-adjusted using a standard display test tube (not shown) Non-standard display The paper scale is applicable to the Chinese national standard (CNS> A4 specification (2 丨 0X297mm) ~ _ ~~ ---- ^ ------- 1 ^ ------ 1T --- ---- 0-~ (please read the precautions on the back before filling in this page) A7 B7 Printed by the Central Standards Bureau of the Ministry of Economic Affairs, Male Workers ’Consumer Cooperative V. Invention description (4) The display tube of the tube, so sometimes Occurs in the color display device, the difference in mechanical or electrical characteristics between the sassafras tube and the production tube. In this case, the scorpion is used to correct the additional adjustment of defocus. An additional catcher 3 4 uses To correct this defocus, as shown in Figure 6, and the compensation sheet 34 is fixed to the ribs 22 and 24 by the adhesive 36. The disadvantages of this additional adjustment are as follows. ^ Additional capture The piece 3 4 cannot be temporarily held in the desired position. When the adhesive hardens, the compensation piece; 4 tends to move from its set position: moving-. When the compensation piece 3 4 cannot It is difficult to correctly set the catcher 34 when moving and temporarily maintaining it in the desired position. SUMMARY OF THE INVENTION The present invention is to solve the above problems, and the purpose of the present invention is to improve the durability of the separator, It also has good productivity. Another hundred of the invention is to improve the workability of attaching the compensation sheet on the deflection yoke and to improve the accuracy of correction. A further and other object of the invention is to provide the deflection yoke Design features. One of the characteristics of the present invention is that the center of the compensator installed on the edge of the separator has a curved portion * to use its elasticity to be placed on an edge.
