Title: Distribution line carrier transmission and reception system
Inventor: FUKUMOTO YOSHIHIRO
IPC: H04B3/54
Filed: 1985-04-24
Abstract: PURPOSE:To allow a reception station to receive always a signal even when a standing wave phenomenon is caused by providing both a current detector and a voltage detector to the reception station so as to receive the signal in terms of both current and voltage. CONSTITUTION:A sinusoidal wave signal sent from a transmission station 5 exists on a distribution line 3 in a form of a standing wave when the signal frequency is high or the range of the distribution line 3 is long. In neglecting the loss by the distribution line, both the voltage standing wave and the current standing wave are sinusoidal waves and their maximum values are shifted by 1/4 wavelength. When the reception station 4 is placed near a point B, although the signal cannot be received as a voltage but received as a current. When the reception station 4 is placed near a point A, the signal cannot be received in a form of a current but in a form of a voltage. Thus, even when the standing wave of the signal takes place, the signal is received always by detecting the signal in both forms of current/voltage.

Title: Circuit for eliminating base resistance distortion of reverse amplifier
Inventor: NOGUCHI TADASHI
IPC: H03F1/34
Filed: 1982-05-27
Abstract: PURPOSE:To eliminate the signal distortion, by avoiding variations of both input resistance and feedback resistance values by a positive or negative input signal. CONSTITUTION:The bases of PNP transistor TRQ1, Q4 and Q7 are connected to an input terminal I, an earth terminal E and an output terminal O respectively. Therefore an input signal ei+base-emitter voltage VBE, the voltage VBE and an output signal eo+VBE emerge at the emitters of those TRs respectively. While NPN transistors TRQ2 and Q3 and Q5 and Q6 function as differential amplifiers respectively. The emitter potential is obtained by subtracting the voltage VBE from the higher one of two base potentials and then applied to an input resistance Ri and a feedback resistance Rf as a bias respectively. Thus Ri=Rf is always satisfied, and the gain of a reverse amplifier can be kept as -Rf/Ri=-1. This eliminates the conventional signal distirtions.
