DOUBLE-BEAM CATHODE-RAY TUBE WITH MAGNETIC DEFLECTING YOKE Russian patent published in 1995 - IPC

FIELD: cathode-ray tube manufacture. SUBSTANCE: device has envelope, magnetic deflecting yoke, optoelectronic system incorporating electron guns, electrostatic precision beam alignment system separated by diaphragm, each mounting horizontal offset system plate. Second plates of these systems are secured, respectively, on last electrode of one gun and on first electrode of focusing system. To eliminate effect of beam on characteristics, correcting systems are placed at mean potential of adjacent electrodes; to this end, separating diaphragm is joined with accelerating electrode. Additional diaphragms carrying second plates of electrostatic systems have separate leads placed at potentials aligning beams. EFFECT: improved design. 2 dwg
