Title: 3d system amplifier circuit
Inventor: HAMADA MASANORI
IPC: H04S1/00
Filed: 1984-07-19
Abstract: PURPOSE:To realize proper gain distribution for amplifiers for an intermediate/ high sound range and low sound rage by installing a sound volume controller which gradually reduces the output of the low sound range when a sound output from right or left channel is increased by a variable resistance. CONSTITUTION:After sound signals Lch and Rch at the right or left and inputted to and amplified by amplifiers 1L and 1R through variable resistances B and C respectively, they are reproduced by speakers 5L and 5R. The signals Lch and Rch through the resistances B and C are inputted to a low sound amplifier 3 through a variable resistance A and reproduced by a speaker 4 after signals in the prescribed intermediate/high sound range removed by an LPF 2. The resistance A is constituted in such a way that it is interlocked with the resistances B and C, and set to low output contrary to the resistances B and C set to high output. Thanks to this constitution, the output of the low sound becomes greater than that of the intermediate/high sound range when a reproduced sound volume is comparatively small. On the other hand the output of the low sound becomes smaller when the reproduced sound volume is large.

Abstract: PURPOSE:To omit the useless blank spaces of the recording paper by setting a fixed number of communication results in response to the size of the recording paper when the communication results are recorded on the recording paper after the communication results reach a fixed number. CONSTITUTION:When the reception information is received from the remote side via a telephone circuit 5, an NCU 4, and a MODEM 7, a control part 1 drives a printer to receive the information. At the same time, the communication result is recorded into a RAM 2 as the communication control record for each execution of the receiving operations. When the number of communication results reaches a fixed level (recording start number of pieces), the printer is driven and the communication results are recorded on the recording paper in the form of a communication control record table. In this case, the recording start number of pieces is changed in accordance with the key input operation of an operator or the size of the recording paper detected by a paper size sensor. Thus it is possible to dissolve a conventional defect where the recording start number of pieces is uniformly set, i.e., the useless blank spaces are produced on the recording paper.

Abstract: PURPOSE:To prevent an operation error by connecting in common the respective emitters of two transistors to the constant-current circuit, and connecting a diode between the collector of one transistor and the base terminal of the base input gate circuit connected to the next stage. CONSTITUTION:When the output OUT1 and the output OUT2 are set to an ''L'' level and an ''H'' level, respectively, in case when the ''L'' level of the output OUT1 has become <=''0'' volt due to some cause, the potential of the point B is also lowered.

And, the diode D4 remains turned off, and a drive current of the transistor Q4 is never cut off.
