Class Information
Number: 315/370
Name: Electric lamp and discharge devices: systems > Cathode ray tube circuits > Cathode-ray deflections circuits > With ray deflection distortion correction or reduction
Description: Subject matter wherein the cathode-ray tube has a cathode-ray beam source and (1) the deflection means is placed in a certain manner or of a configuration to correct or improve the cathode-ray beam pattern caused by the energized deflection means acting upon the beam or (2) there is an electrical element or an electrical network connected to the electrical circuit or the deflection means to correct or diminish the distortion of the beam pattern caused by the energized electrical circuit, deflection means, or the cathode-ray tube.
