  • Patent number: 6172451
    Abstract: A deflection yoke includes horizontal deflection coils; vertical deflection coils; and coils for correcting a vertical pincushion distortion, which coils are provided aside from the vertical deflection coils; wherein the coils for correcting a vertical pincushion distortion have such a wire-wound form as to generate a magnetic field having a pattern substantially equal to that of the vertical deflection coils. This is effective to carry a parabolic current with horizontal cycles for correcting a vertical pincushion distortion at a low voltage, and hence to simplify the circuit configuration and reduce the manufacturing cost.

  • Patent number: 5714921
    Abstract: A horizontal coil separator has a plurality of ribs for positionally controlling turns of a magnet wire, the ribs project successively stepwise in an axial direction of a cathode-ray tube. The turns of the magnet wire are bent over at respective positions staggered in the axial direction of the cathode-ray tube, depending on the winding position of the magnet wire as determined by the ribs. The ribs have fingers disposed on distal ends thereof for positionally controlling only opposite ends of the turns of the magnet wire.
