Cathode Ray Tube

Clad metal or electron beam welded metal is used as an integral part of the compensated suspension system of color television shadow mask frame assemblies. The thermostat metal spring is compressed at its hole, which is suspended onto a tapered stud protruding from the front glass panel. When the television tube is energized, electron bombardment of the shadow mask results in heating and consequent expansion of the mask. The thermostat metal responds to the temperature change and adjusts the position of the mask to correct the focal distance between the electron guns and the mask, maintaining color fidelity.
