摘要： PURPOSE:To correct optionally dynamic convergence by sticking a magnetic material to the peripheral part of a deflecting yoke and controlling a residual magnetic flux programmably. CONSTITUTION:Corner correcting a magnetic materials 31-34 are stuck to the peripheral part of a deflecting yoke 2, and each magnetic material is magnetized and degaussed by magnetizing yokes 41 and 42, and color diviation in horizontal and vertical directions is compensated by the residual magnetic field. In this case, a test pattern projected onto a color CRT1 is picked up by an ITV5, and a monostable multivibrator 21 is triggered when the scanning line designated by a CPU13 coincides, and a picture is divided into 5 in the horizontal direction by the output, and a color signal peak is detected in an optionally position by a peak position detecting means 11, and the time width between peak positions is measured by a means 12, and the CPU13 determines an extent of color deviation on a basis of this measured value and gives compensation quantity data to a magnetizer 17. Thus, magnetizing yokes 41 and 42 are magnetized in DC to generate a residual magnetic flux density, and the dynamic convergence of each corner part is compensated.

摘要： PURPOSE:To reduce the temperature increase of the horizontal deflection coil by using a vertical deflection coil prepared by twisting a few conductors together and then twisting several of thus prepared strand groups together. CONSTITUTION:A deflection york for a cathode-ray tube is made by winding a horizontal deflection coil 2 and a vertical deflection coil 3 around the slots 5 of a core 4. The horizontal deflection coil 2 is a quadruple Litz wire consisting of 3 strands and prepared, for example, by twisting three strands together and then twisting four of thus prepared strand groups together. The vertical deflection coil 3 is a triple Litz wire consisting of 3 strands and prepared by twisting three strands together and then twisting three of thus prepared strand groups together. Owing to the above structure, the skin effect between the horizontal and the vertical coils 2 and 3 is reduced and the increase of loss resistance resulting from the influence of adjacent parallel conductors is reduced. Consequently, it is possible to reduce the temperature increase of the horizontal deflection coil 2 during driving of high deflection frequency.
摘要翻译：目的：通过使用通过将几根导体绞合在一起制成的垂直偏转线圈，然后将几个这样制备的线束组合在一起，来降低水平偏转线圈的温度升高。构成：用于阴极射线管的偏转约束通过将水平偏转线圈2和垂直偏转线圈3缠绕在芯体4的狭槽5上而制成。水平偏转线圈2是由3 <4 并且例如通过将三股绞合在一起，然后将四个由此制备的线股组合在一起而制备。垂直偏转线圈3是由3条3股线组成的三联线，通过将三条线绞合在一起，然后将三根如此制备的线股组合在一起而制备。由于上述结构，水平和垂直线圈2和3之间的表面效应减小，并且由相邻的平行导体的影响引起的损耗阻力的增加减小。因此，可以在高偏转频率的驱动期间降低水平偏转线圈2的温度升高。
