AUTOMATIC DEVICE CONTROLLING KNOCKING AND AGING VOLTAGE OF CATHODE-RAY TUBE

摘要

an initial voltage applying part for applying an initial voltage to a valve; a voltage-current detecting part for detecting the voltage and current values of the knocking/aging voltage; a voltage controller for recontrolling the applying voltage when the voltage and current values detected by the voltage and current detecting part is above the permissible error; and a controlled voltage applying part for applying the controlled voltage to the valve.
