  • Deflection yoke for a color cathode ray tube
    Patent number: 4433268
    Abstract: A deflection yoke for a color cathode ray tube is disclosed which does not cause raster distortion and avoids electron beam convergence error. Both horizontal and vertical deflection coils generate fields having a pincushion distribution. Front end magnetic members extend the pincushion type vertical deflection magnetic field toward the viewing screen of the tube. Rear end magnetic members deform one portion of the magnetic field generated by the vertical deflection coils into a barrel type so that the sum of the vertical deflection magnetic field is effectively a barrel type distribution.
