    • The invention provides a deflection yoke (41) which can simultaneously achieve suppression of induction current arising from an influence of a raster rotation correction coil and correction of misconvergence which varies the current balance of horizontal deflection coils. The deflection yoke of the present invention includes a raster rotation coil, and a pair of coils (51, 53) sharing single core and respectively connected in series to an upper side horizontal deflection coil (57) and a lower side horizontal deflection coil (59). The pair of coils (51, 53) are connected such that the polarities thereof may be opposite to each other. The pair of coils (51,53) suppress current induced by a magnetic field of the raster rotation coil. In order to apply a bias to the pair of coils (51, 53) which share the core, a single bias coil (55) is wound on the shared core on which the pair of coils (51, 53) are wound. Part of horizontal deflection current is supplied to the bias coil thereby to produce a difference in current flowing through the upper side horizontal deflection coil (57) and the lower side horizontal deflection coil (59). Correction of misconvergence is allowed thereby.

    • 本发明提供了一种偏转线圈(41),其可以同时实现由光栅旋转校正线圈的影响引起的感应电流的抑制以及改变水平偏转线圈的当前平衡的失会聚的校正。 本发明的偏转线圈包括光栅旋转线圈和共享单个磁芯并分别串联连接到上侧水平偏转线圈(57)和下侧水平偏转线圈(59)的一对线圈(51,53) )。 一对线圈(51,53)被连接成使得其极性可以彼此相反。 一对线圈(51,53)抑制由光栅旋转线圈的磁场引起的电流。 为了对共享芯的一对线圈(51,53)施加偏压,将单个偏置线圈(55)缠绕在共享芯上,该共享芯上缠绕有一对线圈(51,53)。 水平偏转电流的一部分被提供给偏置线圈,从而产生流过上侧水平偏转线圈(57)和下侧水平偏转线圈(59)的电流差。 因此可以纠正失会聚。
