    • A bar-shaped element includes magnets at both ends and a magnetic material connecting the magnets to each other. One end in a major axis direction of the bar-shaped element is an N-pole, and the other end is an S-pole. A pair of bar-shaped elements sandwich a deflection yoke in a horizontal direction, with the major axis direction thereof being parallel to a vertical direction, and each of the bar-shaped elements is placed at a position between the end of a horizontal deflection coil on a phosphor screen side and a central position of a core in a tube axis direction, in such a manner that the magnetic poles at both ends are opposite to each other between the pair of bar-shaped elements. Because of this, PQH misconvergence is corrected without influencing power consumption at low cost by a simple method without using an auxiliary coil and a correction circuit, whereby satisfactory convergence can be realized.
    • 棒形元件包括两端的磁体和将磁体彼此连接的磁性材料。 棒状元件的长轴方向的一端为N极,另一端为S极。 一对棒状元件在水平方向上夹着偏转线圈,其长轴方向平行于垂直方向,并且每个条形元件被放置在水平偏转线圈的端部之间的位置 在荧光屏侧和芯轴的中心位置,使得两端的磁极在一对棒状元件之间彼此相反。 因此,在不使用辅助线圈和校正电路的情况下,通过简单的方法来校正PQH失会聚,而不会以低成本影响功耗,从而可以实现令人满意的收敛。
