CATHODE-RAY TUBE WELDING GUN Russian patent published in 1995 - IPC

Abstract SU 1799190 A1

FIELD: welding under conditions of enhanced gas emission. SUBSTANCE: invention in aimed at increase of electric strength of gun due to growth of degree of screening of electrodes against development of direct or surface discharge. Gun has cathode, controlling electrodes, anode, light waveguide, insulating elements made from solid dielectric, deflecting and focusing coils. At least controlling electrode is positioned inside body of insulating element. EFFECT: increased electric strength of gun. 1 dwg
