Low the color picture tube which possesses the expansion which is installed in the high expansion frame tension mask

摘要

The color picture tube (10), the tension mask which is supported the support frame which is installed on the image reception inside of pipe (28) by (24) it possesses. The mask has the coefficient of thermal expansion which is lower than the frame significantly. The intermediate component (48 and 80), it is installed with the mask and the frame. The intermediate component consists of the material which possesses the coefficient of thermal expansion which resembles to the coefficient of thermal expansion of the mask. The long tub where the frame, extending it is present from the frame (46, 70 and 76) it possesses. Each tub is installed in the remaining part of the frame in one edge of the tub. The distal (2036) edge of the tub is welded in the intermediate component.
