Filed: 1982-11-04
Abstract: PURPOSE:To improve the stabilization of an output voltage and to lower the ripple content rate by controlling a drive pulse generator which drives a variable impedance connected in parallel with the output side of a rectifier and a switching circuit.

Filed: 1985-09-02
Abstract: PURPOSE:To ensure the two-way communication even with power application in any timing by making transmission in a longer time than the transmission time of an opposite station at power-on or reset. CONSTITUTION:When th switching signal T/R input at the transmission/reception mode is in a low state, a transmission end detection circuit 7 detects the end of transmission and outputs a pulse D, then an output of an AND circuit 13, that is, the T/R input of an optical transmission module 2 goes to high level vie an OR circuit 11 and an FF 12 and the transmission mode is changed into the reception mode. Similarly, the reception mode is switched to the transmission mode by the output of a reception end detection circuit 6. Further, after the signal is sent in a lonter time than the maximum transmission time at power-on or reset, the mode is switched from the transmission mode into the reception mode. Thus, the delay time t1 of the output B of a Schmitt trigger inverter 8 is set larger than the maximum transmission time 2t3.
