Abstract
PURPOSE: To prevent thermal deformation and to increase the preformance of color Braun tube, by removing the strain for the assembling of frame, bimetal, and springs with heat treatment and assembling the shadow mask.
CONSTITUTION: In the process of assembling of the shadow mask 3 of the color Braun tube, first the frame 8, bimetal 9 and spring 10 are assembled to a given size. Next, the strain is removed by making heat treatment at ta temperature corresponding to the heat temperature in the fleet seal process, that is, 450 to 550°C. After that, since no heating process is present from the completion of assembling of the mask 3 to the formation of fluorescent screen and no mask distortion is caused in the heat process after the formation of fluorescent screen, then the preformance of the Braun tube can remarkably be increased.
