Abstract

PURPOSE: To detect and eliminate early factors which cause the deterioration of dielectric strength characteristic by adding a process where the negative voltage is applied to the anode before the maximum rated voltage is applied to it and testing dielectric strength characteristic of the cathode-ray tube.
