Title: Automatic answer type sound recorder
Inventor: NUKADA FUMIAKI
IPC: H04M1/64
Filed: 1983-05-12
Abstract: PURPOSE:To use an ordinary tape recorder also to an automatic answering telephone type sound recorder by controlling the drive and stop of an answering endless tape or a recording tape after detecting a no-sound section of the answering endless tape. CONSTITUTION:When terminals 1 and 2 receive the incoming call signals, an incoming call signal detecting part 3 works. When the incoming call signal is transmitted to a control part 7, the part 7 actuates a relay to close contacts 17 and 18. As a result, a circuit is held and a tape recorder 20 works. Then the contents of a tape 21 are sent to the circuit via a terminal 8, a contact 15, a sound coupling part 5 and the terminals 1 and 2 respectively. At the same time, the part 7 starts to check the presence or absence of a no-sound section in the sounds sent from the tape 21 through a no-sound detecting part. In such a way, an ordinary tape recorder can be used also to an automatic answering telephone type sound recorder without further remodeling.

Title: Circuit provided with operational amplifier with offset temperature drift compensation function and offset temperature drift compensation method
Inventor: ADACHI TOSHIO
IPC: H03F3/34
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To eliminate an offset temperature drift of the entire circuit including an operational amplifier without separately providing the temperature compensation circuit. SOLUTION: Device sizes of differential pair transistors(TRs) 13, 14 included in an operational amplifier are selected unbalancedly by intention. Then an offset voltage is proportional to a current of the unbalanced TRs by the operation of a feedback circuit of the operational amplifier and inversely proportional to a current of a trans-conductance of the input TRs. Since the trans- conductance has temperature dependency, the offset voltage is drifted by temperature. As a result, the offset temperature drift of the entire circuit is compensated.
