Title: Voice switching device
Inventor: WAKABAYASHI HIROSHI
IPC: H04B1/46
Filed: 1983-03-23
Abstract: PURPOSE:To prevent one's word beginning and ending from being cut off by operating a channel changeover switch with an output of a mute detecting circuit and controlling the device with a self-hold type comparator. CONSTITUTION:When a transmission signal is lost and a receiving signal comes, an output of the self-hold type comparator 11 opens a transmission line switch 4 and closes a receiving line switch 5 so as to bring the state into the receiving state, and the mute detecting circuit 13 detects the receiving signal so as to open the transmission line changeover switch 12. Thus, the receiving signal only is inputted to the comparator 11 and no reception blocking takes place. Further, when no receiving signal exists at the receiving state, although neither transmission signal nor receiving signal is inputted to the comparator 11, since the comparator 11 is of the self-hold type, the receiving state is kept and a hangover time is obtained automatically thereby preventing one's word ending from being cut off. On the other hand, since no receiving signal exists, the circuit 13 closes the switch 12 to input the transmission signal to the comparator 1. The comparator 11 keeps the receiving state and receives both the inputs of the transmission and receiving signals, and when the transmission signal level is higher than the receiving signal level, the self-hold is released and the mode is brought into the transmission state.

Title: Through-current preventing circuit
Inventor: SHIMADA TOSHIRO
IPC: H03K19/00
Filed: 1986-03-06
Abstract: PURPOSE:To decrease the power consumption by making one bipolar transistor (TR) into nonconductive state by the electric charge stored in a base terminal of other bipolar TR constituting the output stage to switch the output stage. CONSTITUTION:Even when the 1st input signal changes from the high level state into the low level state, while an electric charge stored in the base terminal of an NPN TR 1 is discharged completely when the 1st input signal is in the high level state, an NPN TR 7 keeps the conductive state by the electric charge. Thus, a current flows to the base of an NPN TR 9 from a voltage source Vcc via the NPN TR 7 and a resistor R to make the NPN TR 9 conductive. Thus, even when the 2nd input signal is in the high level state, since the NPN TR 9 is conductive, the base potential of an NPN TR 3 is nearly at a ground potential and the NPN TR 3 is made nonconductive. Thus, the through-current flowing from the voltage source Vcc to ground at the switching of the NPN TRs 1, 3 is prevented.
