IPC: H02M1/08
Filed: 1978-09-27
Abstract: PURPOSE: To make the level of a turn-on signal for a light-triggered thyristor high enough, by sequentially emitting rays of light from a plurality of light-emitting members at prescribed delay timing by an electric signal generator, optically adding the rays of light to one another and supplying the added light to the thyristor.  
     CONSTITUTION: An electric signal generator 1 has delay circuits corresponding to a plurality of light-emitting diodes 2 and supplies electric signals to the diodes 2 at prescribed delay timing. Light signals are emitted from the diodes 2 and concentrated to a single optical fiber unit at an output end through optical fiber members 3 separately provided for the light-emitting diodes 2 to turn on a light-triggered thyristor 4. The pulse widths W of the light-emitting diodes 2 are synthesized with one another so that a larger pulse width n×W is obtained for turning on the thyristor 4. Therefore, the light-triggered thyristor 4 can be turned on with high reliability without shortening the lifetime of each light-emitting diode.

Filed: 1992-04-13
Abstract: PURPOSE: To provide an error amplifier capable of in-phase drive by providing a differential amplifier stage having two input terminals and one output terminal, a MOS transistor(TR) and a diode. CONSTITUTION: A potential at an output terminal 20 and a potential at a drain terminal of a MOS TR 24 are in phase by mirror processing of a potential at output terminals of differential amplifier stage MOS TRs 23-25 to a gate terminal of a MOS TR 10 in the error amplifier 14.

Furthermore, in the case of feedback coupling, a level shift is used to keep the MOS TR 25 in a saturation state. In the case of forward drive, a potential at the output terminal 20 of the differential amplifier stage is kept to a potential equal approximately to a positive supply potential 18 and not jumped to a negative supply potential 19.  Thus, high drive performance of the error amplifier 14 is attained and the output TR 10 is optimizingly driven.

Title: Semiconductor integrated circuit
Inventor: OGATA KATSUHITO
IPC: G11C11/401
Filed: 1989-05-12
Abstract: PURPOSE:To attain the stable working of a semiconductor integrated circuit IC by using an output signal PON of a power voltage detecting circuit and keeping the IC in a reset state until the signal PON is turned off after application of a power supply. CONSTITUTION:All nodal points of a semiconductor IC are kept at GND levels before application of a power supply. The output PON of a power voltage detecting circuit 1 outputs a high level continuously until the power voltage rises up to a certain level while the power voltage is raised up to a stable working enable level from the GND level. Meanwhile the output N1 of a NOR 1 is kept at a low level. At the same time, a RAS system control circuit 2 is reset regardless of a signal, the inverse of RAS. Thus each nodal point to be precharged can be reset. Then the nodal point of the N1 is turned into the inverse data of the signal, the inverse of RAS when the power voltage rises up more and the PON is set at a low level. Thus the normal working of the circuit 2 is attained. As a result, the ON-ON current of a MOSFET produced by an unstable nodal point of an internal circuit is eliminated at application of a power supply. Then the stable working of the semiconductor IC is attained.
