摘要： An arc-resistant deflection yoke for a cathode ray tube deflection system includes a core of magnetic material having a pair of axes with first and second deflection windings toroid-wound in mirror image relationship on opposite sides of one axis and third and fourth deflection windings toroid-wound in a continuous-wound relationship on opposite sides of the other axis. The arc-resistant deflection yoke is fabricated by a process of selecting a core, toroid-wrapping first and second windings on opposite sides of one axis in mirror image of one another and toroid-wrapping third and fourth windings on opposite sides of an opposite axis in continuous-wound relationship.

摘要： 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 separate primary windings to the horizontal output transistor to optimize the driver stage and conserve power.

摘要： CRT mounts for color television are effectively high voltage conditioned by impressing a high voltage DC potential on the mount anode, while at the same time impressing a high frequency pulsed AC potential on the final grid electrode, and allowing the focusing electrode to float electrically, thereby inducing arcing in the upper and lower gaps adjacent the focusing electrode. Preferably, this general conditioning is followed by a second conditioning step in which the focusing electrode is connected to the AC potential, to concentrate the arcing in the upper gap.

摘要： 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 provide a sawtooth drive current to the horizontal output transistor sufficient to maintain the horizontal output transistor in saturation without wasting excessive power. The output winding is tightly coupled to the second input winding to provide a sharp turn-off pulse to the horizontal output transistor.

摘要： 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 for providing a pulse to the retrace driver in response to termination of the trace drive signal by the trace driver.

摘要： A color cathode ray tube having feedback features including a phosphor pattern on the mask and a window in the tube wall to allow external detection of the phosphor emissions, also incorporates arc limiting features including a high resistance coating in the neck region of the tube and a lower resistance coating underneath the arc limiting coating in the region of electrical contact between the arc limiting coating and the electron gun. The composite coating is effective to reduce erosion of the arc limiting coating in the area of snubber contact during high voltage conditioning of the tube. Such a tube is useful, for example, for high resolution color displays having an automatic convergence feature.
