Abstract: A deflecting yoke apparatus comprising first and second frame coils configured to correct a vertical horizontal misconvergence first and second main coils and first and second sub-coils which are wound around a core and configured to deflect in a vertical direction electron beams which have passed through a magnetic field generated by the first and second frame coils, a first deflecting current supply portion configured to pass a serriform deflecting current to the first and second main coils, and a second deflecting current supply portion configured to supply to the first and second sub-coils through a first and second diodes connected in parallel so as to have opposed directions a deflecting current which is supplied to the first and second main coils by the first deflecting current supply portion.

Abstract: A pair of saddle type horizontal deflection coils are provided at those upper and lower places on the inner wall of the coil separator. Vertical deflection coils toroidally wound on a core are provided on the outer periphery of the coil separator. Neck-side magnetic pieces are provided at those upper and lower sides of the neck-side area between the coil separator on one hand and the vertical deflection coils on the other hand. A pair of magnetic pieces, right and left, are provided, as a pair of crossarms, on the coil separator at a front-side section. In a deflection yoke apparatus thus provided, magnetic field creation areas at the crossarms are provided mainly on a Y axis side and four permanent magnets are provided on the front-side flange section of the coil separator at an angle of about 10.degree. relative to an X axis so that these permanent magnets are magnetized substantially in a tube direction of a CRT.
