Title: Shock noise preventing circuit
Inventor: NAGATA MITSURU
IPC: H03F1/00
Filed: 1987-06-29
Abstract: PURPOSE:To obtain a circuit with a simple constitution and not hindering the transmission characteristic of an amplifier by providing a 3rd transistor (TR) whose collector is connected to a base of a TR of an SEPP amplifier, whose base is connected to a momentary constant voltage section and whose emitter is connected to a reference voltage source respectively. CONSTITUTION:The collector of a TR Q10 is connected to a base of a TR Q4 of the SEPP amplifier A2, the base is connected to a base of a TR Q11 whose base potential is momentarily at a constant level when the power switch SW is turned on and the emitter is connected to an output P of a reference voltage source 1 via a resistor R3 respectively. In turning on the switch SW, the base potential VR of the TR Q11 is going to rise momentarily. Since the reference voltage Vref of the output P is initially 0V, the collector current of the TR Q14 is attracted entirely in the TR Q10 to decrease the base potential of the TR Q4 close to the ground potential. As the voltage Vref approaches the final value, the TR Q10 is turned off smoothly after the switch is turned on and the potential at an output terminal VOUT reaches gradually the final voltage Vref and no shock noise takes place. No additional circuit is required to be connected to the base of the TR Q3 and the voltage gain of the amplifier A2 is zero and the effect given to the transmission characteristic is less.

Title: Multiplexer
Inventor: BABA KOICHIRO
IPC: H04L5/22
Filed: 1992-06-19
Abstract: PURPOSE:To use the band efficiently by sending data to be sent when the data to be sent are in existence in the non-use state where no valid information is sent to a transmission line. CONSTITUTION:An SS signal being a voice control signal from a telephone set via an exchange is set to a ground level and a start signal is sent. An SS signal detection circuit 103 of a multiplexer 100 detects that the SS signal is set to a ground level and informs it to a control means 106. When the SS signal is set to a ground level, the control means 106 controls a transmission buffer 107 not to send data and commands cell processing of the voice signal to a voice cell processing circuit 104. The circuit 104 processes a time slot of the SS signal and the voice signal into a cell. A multiplexer circuit 108 multiplexes and sends the result. Furthermore, when the telephone set is not busy, the means 106 processes only the control signal of the SS signal and sends the result. In this case, the means 106 controls a buffer 107 to send a data cell.
