  • Deflection yoke for use with in-line cathode ray tubes
    Patent number: 4041428
    Abstract: A deflection yoke for use with an in-line cathode ray tube in which a plurality of electron beams are laid, for example, in a horizontal plane, which has a horizontal deflection winding formed in the saddle shape with front and rear bends for producing a pincushion type magnetic field and a vertical deflection winding wound toroidally around a magnetic core to surround the horizontal deflection winding between the front and rear bends for producing a barrel type magnetic field, wherein the vertical deflection winding is shorter than the distance between the front and rear bends of the horizontal deflection winding and is positioned adjacent the front bend and with a predetermined space from the rear bend. The use of the deflection yoke with the in-line cathode ray tube can eliminate or simplify a dynamic convergence correcting device.
