Abstract

THERE IS PROVIDED A CATHODERAY TUBE INCLUDING AN ENVELOPE HAVING A NECK (10), A FUNNEL (2) AND A PANE) (1) FUSED TO THE FUNNEL (2) BY USING FRIT GLASS, THE OUTSIDE OF THE PANEL (I) BEING NEAR FLAT, THE INSIDE OF THE PANEL (1) HAVING A PREDETERMINED CURVATURE, IN WHICH 1.7 T2ITI <2.3 WHEN TI IS THE THICKNESS OF THE CENTER OF THE PANEL (1) AND T2 IS THE THICKNESS OF THE DIAGONAL CORNER OF THE PANEL (1), AND A PANEL INSIDE TENSILE STRESS AT THE FUSED PORTION OF THE PANEL (I) AND FUNNEL (2) IS LESS THAN (-I .3876X ÷ 128.24) 98066.5 MPA [-1.3876X + 128.24 (KGF/CM2)) WHEN THE SIZE OF THE EFFECTIVE PICTURE AREA OF THE CATHODE-RAY TUBE IS X (UNIT: CM). THE PANEL INSIDE TENSILE STRESS AT THE FUSED PORTION OF THE PANEL (1) AND FUNNEL (2) IS MAINTAINED BELOW A PREDETERMINED VALUE TO MITIGATE BREAKAGE INSIDE THE FURNACES THAT OCCURS WHEN THE CATHODE-RAY TUBE HAVING THE PANEL (1) WHOSE OUTSIDE IS NEAR FLAT AND WHOSE INSIDE HAS A PREDETERMINED CURVATURE IS REPRODUCED, THEREBY IMPROVING THE SALVAGE RATE.
