Patent JP-S58187007-A (JP)
Title: Push-pull amplifier circuit
Inventor: KONDOU HIKARI
IPC: H03F3/30
Filed: 1982-04-27
Abstract: PURPOSE:To reduce harmonic distortion peculiar to an active bias system, by connecting PNP and NPN transistors(TRs) of the 1st stage via a constant current circuit. CONSTITUTION:An input signal from an input signal source 1 is applied to a load 10 via TRs Q1, Q2, Q3, Q4 of Darlington connection, and the output is inputted to an active bias circuit 2. The bias is changed in response to the change in the output emitter current of the TRs Q3, Q4. The emitters of the TRs Q1, Q2 are connected via a constant current circuit 11. Thus, even if a voltage between points A and D is changed with the active bias circuit 2, the emitter current of the TRs Q1, Q2 is constant and the base current change (distortion current) of the TRs Q1, Q2 is eliminated.

Abstract: PURPOSE: To make it possible to change a demand interval simply, by a constitution where the frequency division ratio of input pulses can be switched according to different demand intervals.  
     CONSTITUTION: The transmission pulse received by input terminal 6 is input to current interval counter 4 after 1/2 frequency division in frequency dividing circuit 8 if selector switch 9 is switched to demand interval 60min-side contact 91. If selector switch 9 is switched to demand interval 80min-side contact 92, the transmission pulse is input directly to current interval counter 4. The pulse conversion ratio of input to current interval counter 4 between demand interval 60min and 80min is 1:2, and demand electric power determined by the function to the demand interval becomes 1:1 finally. The pulse which passed through selector switch 9 is added to maximum value memory unit 1 through current interval counter 4 and so on. By this constitution, it is possible to cope with demand interval change simply without change of the maximum demand meter by the selector switch and so on.
