Title: Battery saving system for radio receiver
Inventor: SAITOU AKIO
IPC: H04B1/16
Filed: 1980-03-26
Abstract: PURPOSE:To eliminate queuing time required for a call, by causing a transmitter to transmit the same call signal for two frames out of transmission signal frames and by causing a receiver to turn on the power source for every other frame. CONSTITUTION:Call signal A for a desired receiver is inserted to continuous frame numbers 3 and 4 of the transmission signal and is transmitted from the transmitter. Since power is supplied to the receiver of the car telephone set or the like synchronously with every other frame of the receiving signal, the receiver receives the receiving signal of frame number 3 or 4. Consequently, in this system, power consumption during the use is reduced to half, and the receiver is set to the state where  it can receive the signal without delay for transmission of the call signal.

Title: Ttl circuit
Inventor: HOASHI MASAAKI
IPC: H03K19/013
Filed: 1982-03-12
Abstract: PURPOSE:To accelerate a response and to prevent the generation of a distortion output, by abosrbing the stored charge of a transistor which forms the output stage of a TTL circuit by a capacitor which is charged alternately through both poles in response to level variations of an input signal. CONSTITUTION:A discharging circuit 2 is provided with a transistor TRQS, a resistance RS which supplies a base current and a capacitor CS which absorbs the stored charge. The emitter of the TRQS is connected to the base of a TRQ6. When the input signals to terminals A and B are set at H levels, the TRQ6 and TRQ1 are turned on. Thus the charging current flows to the TRQS and the capacitor CS. When either one of these two terminals is changed to an L level, the TRQ6 is turned on. Then the charge stored at the base of the TRQ1 is absorbed to the capacitor CS. Therefore the switching time is shortened to eliminate the distortion of a waveform when the TRQ1 is changed to OFF from ON.
