COLOR KINESCOPE (VERSIONS) Russian patent published in 1997 - IPC

FIELD: TV equipment. SUBSTANCE: color kinescope comprises vacuum glass envelope with face panel having cathode luminescent screen where luminophor sections of various colors are deposited. Panel has unit "shadow mask-frame" mounted on it with the aid of anchoring means arranged over periphery inside panel. Shadow mask includes aperture part which apertures are matched with luminophor sections of screen. Each anchoring means has lockpin attached to glass envelope, spring having hole for coupling with lockpin and plate welded between spring and unit "shadow mask-frame". Updating consists of mechanical connection of spring and plate with the use of protrusions bonding these two parts in two different points along one edge of these parts. Due to this, spring and plate partially contact each other along outer surfaces. Bonding protrusions impart spring and plate with resistance to movement which causes impact action thus decreasing mismatch between apertures in mask and luminophor sections of screen. EFFECT: enhanced functional stability. 10 cl, 7 dwg
