Title: Current switching device
Inventor: MARUTA HIDEICHIROU
IPC: G05F3/26
Filed: 1982-03-26
Abstract: PURPOSE:To flow a constant current to a load of each phase by turning on/off a load current through a switching transistor (TR), and feeding the load current back negatively to a differential amplifier and controlling the current flowing through the TR. CONSTITUTION:When a positive signal is inputted as a signal Ha, a TRQ7 turns on and a TRQ6 turns off. Consequently, currents flow through TRs Q5, Q7, and Q8 to flow a current through a TRQ1, a load 22, and a resistance R1. The potential difference of the resistance R1 increases in proportion to the current flowing through the load 22. The voltage of the resistance R1 is applied to one terminal of the differential amplifier 25 and as the voltage of the resistance R1 becomes higher and higher, the output voltage of the differential amplifier 25 becomes lower and lower. Consequently, the current flowing through the TRQ8 is suppressed and the current flowing through the TRQ1, i.e. the load 22 is reduced.

Title: Converting circuit of signal level
Inventor: WADA TAKESHI
IPC: H03K19/018
Filed: 1982-03-29
Abstract: PURPOSE:To increase the speed of response, by applying the reference voltage to the collector and the base of a multi-emitter transistor of an input circuit via a diode and a resistance and supplying the output of the reference voltage to a converting part of signal level. CONSTITUTION:When the input signal supplied from a TTL circuit 1 is set at a low level, emitters E1 and E2 of a multi-emitter transistor TRQ1 are turned on and off, respectively. Thus the base potential of the TRQ1 is lower than the reference voltage which is supplied to the emitter E2 from a reference voltage generating circuit 3. Then a TRQ2 and a TRQ3 of a signal level converting part 4 are turned off and on, respectively. Therefore output points OUT1 and OUT2 are set at a low level and a high level, respectively. When the input signal from the circuit 1 becomes higher than a prescribed level, E1 and E2 are turned off and on, respectively. Thus OUT1 and OUT2 are set at a high level and a low level, respectively. The time of response is decided by the time constant obtained by a resistance R1 and a floating capacity CS connected to the collector of the TRQ1. In this case, the R1 can be set at a small value when the outflow current of the E1 is set even by connecting a diode D1 in series to the R1. Thus the speed of response can be increased.
