  • Patent number: 5864204
    Abstract: Disclosed is a supplementary coil of a deflection yoke for a Braun tube. The supplementary coil forms a magnetic field of a pin-cushion type at a screen portion and a magnetic field of a barrel type at a neck portion at the same time. The deflection yoke includes a coil separator for fixing a relative position between horizontal deflection coils and vertical deflection coils by acting as an insulator. The supplementary coil also includes projections formed on inside surfaces of the neck portion and the screen portion of the coil separator. The supplementary coil is wound around the projections in the neck portion in a winding direction identical to a winding direction of the horizontal coil and wound around the projections in the screen portion in a winding direction opposite to the winding direction of the horizontal coil.
