Patent Number Title Of Patent Date Issued
4097784 Quadrupole convergence circuit June 27, 1978
In a color cathode ray tube deflection apparatus having a deflection yoke with horizontal, vertical and quadrupole windings and affixed to a color cathode ray tube, a quadrupole convergence circuit includes a quadrupole winding coupled to a source of substantially parabolic-shaped horizo
4001641 Horizontal deflection system January 4, 1977
A horizontal deflection system with a transformer coupled driver including separate turn-on and turn-off drivers coupled to first and second input windings of the driver transformer is shown. The output winding of the driver transformer is loosely coupled to the first input winding to
3999101 Horizontal deflection system December 21, 1976
A horizontal deflection system with a transformer coupled driver including separate trace and retrace drivers coupled to an input winding or windings of the driver transformer is shown. A feedback or pulse forming means is connected from the transformer to the input of the retrace driver
3993930 Vertical deflection system November 23, 1976
A vertical deflection system including a driver circuit energized by a voltage source having a sufficient magnitude to provide a trace deflection signal to the vertical deflection winding and a retrace voltage source switched into the circuit with the vertical deflection winding to provi
3979640 Horizontal deflection system September 7, 1976
A self-regulating horizontal deflection system with feedback indicative of the magnitude of an unregulated voltage source and of load variations to pulse width modulate the output of the horizontal oscillator is shown. Separate turn-on and turn-off drivers are transformer coupled by sepa
