DEFINITION

Classification: 257/161

With a turn-off diode:

(under subclass 157) Subject matter wherein the regenerative device with amplification means is integrally provided with a diode, i.e., a solid-state active rectifying two terminal device, to bypass the amplifying stage(s), in order to switch OFF the regenerative device.
