Color selecting electrode for color-picture tube and manufacturing method thereof |
摘要 |
A color selecting electrode for a color-picture tube, includes a rectangular frame-shaped frame having a pair of mutually-opposite long sides and a pair of mutually-opposite short sides, and a mask plate which is stretchedly supported on top surfaces of the frame while receiving a resilient spring force exerted from the frame, the long sides having a greater section modulus and a greater rigidity than the short sides. A method of manufacturing the color selecting electrode includes the step of welding, to the frame pressed inward by an equally-distributed force applied to the pair of long sides and the pair of short sides, the mask plate of which four sides are stretched outward by a distributed force which approximately counterbalances the equally distributed force.
