    • PURPOSE: A deflection yoke and a cathode-ray tube device are provided to correct the misconvergence on horizontal lines displayed in the upper and lower parts on its screen by the rasters of side electron beams without seriously affecting vertical deflection sensitivity, and also without the changing of horizontal trapezoid distortion. CONSTITUTION: A pair of saddle-type vertical deflection coils(12R,12L), an auxiliary vertical deflection coils(6a,6b), the first pair of correction coils(2R,2L), and the second pair of correction coils(3R,3L) are sequentially connected in series. Further, resistors(13a,13b) and a variable resistor(14a) are connected in parallel with the pair of saddle-type vertical deflection coils(12R,12L). A variable resistor(14b) is connected in parallel with the correction coils(2R,2L,3R,3L). A resistor(13c) is connected between a point where the correction coils(2L,3R) are connected, and a variable terminal of the variable resistor(14b). The variable resistor(14b) is adjusted to thereby allow an adjustment to the ratio between a current that flows through the first pair of correction coils(2R,2L).
    • 目的:提供偏转线圈和阴极射线管装置,以通过侧面电子束的栅极校正屏幕上下部分显示的水平线上的会聚失真,而不会严重影响垂直偏转灵敏度,也不会改变 的水平梯形失真。 构成:一对鞍型垂直偏转线圈(12R,12L),辅助垂直偏转线圈(6a,6b),第一对校正线圈(2R,2L)和第二对校正线圈(3R, 3L)顺序连接。 此外,电阻器(13a,13b)和可变电阻器(14a)与一对鞍型垂直偏转线圈(12R,12L)并联连接。 可变电阻器(14b)与校正线圈(2R,2L,3R,3L)并联连接。 电阻器(13c)连接在校正线圈(2L,3R)连接的点和可变电阻器(14b)的可变端子之间。 调节可变电阻器(14b),从而允许调节流过第一对校正线圈(2R,2L)的电流之间的比率。
