Abstract: An automatic total inspection system for an implosion-protected cathode-ray tube which measures and inspects the total members of a product by simultaneous and nondestructive tests on some or all items selected from among the thickness of a panel, the positional accuracy and the tension of a tension band for implosion-protection, the positional accuracy and the diameter of a nugget of weld at the welded part of the tension band, and the presence or absence of mounting lugs and a reinforcement plate and the positional accuracy thereof. The adoption of this system enables the inspection process to be carried out without man-power, thereby preventing any error which may be caused by the fatigue of operators, resulting in total inspection with high reliability.
