发明名称 Deflection yoke for color cathode-ray tube having auxiliary coils obviating misconvergence
摘要 A deflection yoke for an in-line self convergence type color cathode-ray tube. The deflection yoke includes an auxiliary coil assembly having auxiliary coils which are electrically coupled with vertical deflection coils and which produce electric field for compensating for misconvergence caused by comatic aberration. The auxiliary coil assembly also comprises a pair of U-shaped cores which are opposed to each other via a neck portion of the color cathode-ray tube and on which the auxiliary coils are wound. The deflection yoke comprises one or more magnetic material pieces, for example, a pair of magnetic material pieces which are disposed on respective one of said U-shaped cores. The one or more magnetic material pieces are preferably made of high permeability metal.
