COPLANAR ELECTRON GUN Russian patent published in 1998 - IPC

Abstract RU 2114483 C1

FIELD: color kinescopes. SUBSTANCE: device has multiple electrodes which are spaced from three cathodes. Electrodes provide at least beam shaping region and main focusing lens at traversal of three beams: central and two side beams. Main focusing lens is provided by two electrodes which pieces are turned to one another. Goal of invention is achieved by design of said pieces of working focusing electrodes which have first member and second member which is located inside first member. First member has bowl-shaped jacket with hole and four spaced projections. Second member is designed as plate with four angles including shifts. Plate with holes is attached to four projections using shifts. EFFECT: decreased precision of manufacturing of electrodes while keeping required characteristics. 4 cl, 3 tbl, 9 dwg
