Thus the code is converted into an analog signal through an MODEM5 to be transmitted to the remote side. When the switching is carried out between the privacy call and the normal call, the carrier wave is detected by a carrier detecting circuit 6 of the receiving side to be applied to an OR circuit 8 via an AND circuit 7. The switching is automatically carried out between the privacy and normal calls by operating a privacy call setting button B1 and a normal call setting button B2 respectively.

Filed: 1984-03-23
Abstract: PURPOSE:To reduce Qrr by softening the reverse recovery characteristic by a method wherein the lifetime is made ununiform in the region with lower impurity concentration of two regions of different conductivity which form P-N junctions where most of reverse voltage is impressed at the time of turn-off operation. CONSTITUTION:An N type Si is put into the P-N-P three layer structure with a P-emitter 12, an N-base 11, and a P-base 13 by diffusing a P type impurity from both surfaces. Next, an N-emitter 14 is formed on the base 13 by diffusion of POCl3, etc. At the time of diffusing a lifetime killer, the lifetime killer is enabled to reach only part of the base by controlling the time and the diffusion temperature; then, only a region in the base 11 close to the emitter 12 is provided with a region where the lifetime decreases. Such a manner causes less accumulation of carriers at the time of on-operation, and they are swiftly exhausted. As a result, the reverse recovery characteristic is softened without deteriorating the ON-characteristic; further, Qrr can be reduced.
