DEFINITION

Classification: 330/138

(under subclass 129) Subject matter wherein the "bias voltage control means" includes a rectifier or discharge device which is biased in such a manner that the rectifier or discharge device will not conduct until a predetermined voltage is reached, which imparts to the control means a "voltage delay" action and wherein the minimum voltage at which bias control begins may be predetermined.
