Abstract
PURPOSE: To obtain the Q size higher in accuracy even for the shadow mask constituent having soft construction with less strength, by fixing the relation of position for the both, after the Q size value between the panel inner surface and the shadow mask assembly is taken optimum.
CONSTITUTION: The shadow mask assembly 16 having soft construction less in the strength and consisting of the mask frame 14 and the shadow mask 15 is welded and fixed as the design by using the springs 4b and 4d with the tool. Further, at the panel inner surface 1, the distance measuring unit 10 of non-contact type in which the size measuring element 10a is attached to the through-hole of the plate 10b having almost the same curvature as the panel 1 is located in contact, the springs 4d and 4b to which the assembly 16 is inserted and welded is mated to the panel pins 2b and 2d, and the assembly 16 is deformed so that the Q size between the panel 1 and the assembly 16 can be optimized while observing the indication of the display unit 13. Finally, the springs 4a and 4c corresponding to the spring pins 2a and 2c corresponding to the panel pins 2a and 2c are welded and fixed to the assembly 16, thus the process is finished.
