  • Cathode ray tube screen exposure system
    Patent number: 4256390
    Abstract: The invention relates to an improvement in the photo-exposure system utilized in the forming of stripe-patterned screens on the viewing panels of color cathode ray tubes. The versatile system incorporates an adjustable electronically controlled cam arrangement for achieving desired oscillation of the exposure light source. A cam associated multi-apertured control disk initiates a pre-determined number of pulses which accurately control the degree of cam movement and resultant light source oscillation.
