COLOR CATHODE-RAY TUBE WITHOUT INTERNAL SCREEN Russian patent published in 1995 - IPC

Abstract RU 2039393 C1

FIELD: color cathode-ray tubes. SUBSTANCE: color cathode-ray tube has bulb built up of funnel and panel mounting electron gun and shadow mask. Internal surface of funnel carries conducting layer of alloy having the following composition, mass percent: Fe 10-87; Ni 11-89; Mn - 0.38-0.58. Conducting layer may contain, in addition, high- resistance material, or high-resistance material, such as titanium, may be placed in region of anode cap and/or electron gun holder contact to transmit voltage from anode cap to electron gun holder contact. EFFECT: improved design. 5 cl, 4 dwg
