Patent JP-H01292917-A (JP)
Title: Photodetecting module
Inventor: NISHIMURA HIDEKAZU
IPC: H04B10/25
Filed: 1988-05-20
Abstract: PURPOSE:To prevent the self-oscillation of a semiconductor optical amplifying element by respectively defining an input coupling space and an output coupling space as optical long-range coupling due to parallel rays and arranging the respective types of optical devices in these coupling spaces. CONSTITUTION:An inputted optical signal and an amplifying signal, which is outgoing from a semiconductor optical amplifying element 106, are caused to be the parallel rays respectively in the input coupling space and output coupling space. Thus, the optical coupling between an input fiber 102 and the semiconductor optical amplifying element 106 and between the output coupling space, namely, the semiconductor optical amplifying element 106 and a photo- detecting element 111 can be defined as the long-range coupling and the various optical devices, etc., can be arranged in these coupling spaces. Here, isolators 104 and 108, which are arranged in the respective input coupling space and output coupling space, transmit only a light to be emitted from an optical fiber 101 to the photo-detecting element 111. Thus, the self-oscillation of the semiconductor optical amplifying element 106 can be prevented.

Title: Power supply device
Inventor: YASHIRO KOUZOU
IPC: G05F1/56
Filed: 1983-07-04
Abstract: PURPOSE:To protect each circuit from the surge voltage of thunder, etc. by providing a switching circuit between an earth and the anode of a diode connected to a thyristor and controlling the switching circuit with the voltage supplied from a flyback transformer. CONSTITUTION:A rectifying/smoothing circuit is connected to the gate of a thyristor S1 with a series circuit of a resistance R7 and a diode D5. At the same time, a transistor (TR)Q4 is inserted between the anode of the D5 and an earth. In such a constitution, the TRQ4 is kept on since the voltage is extremely high at a point C owing to the external surge such as the thunder, etc. Therefore the D5 is never turned on. This prevents a gate current flowing to the S1 due to the external surge, and it is avoided that the S1 conducts by the surge voltage as long as a sufficient amount of flyback pulses are applied to a point A. As a result, the B1 voltage is never increased. In this way, the breakdown of a TRQ3 and other circuits is prevented.

Abstract: PURPOSE:To enable suppression of the occurrence of unnecessary disturbance, by a method wherein when a deviation between a turbine speed and a set speed and a turbine speed forced restoring command signal are outputted, a rate of change in a command signal responding to a process amount proportioning a present output is varied. CONSTITUTION:During control of a turbine speed for a thermal power plant, a turbine speed detected by a speed detector 2 is compared with a signal from a speed setter 3 by means of a speed deviation computer 4, and a determined deviation is inputted to process amount corrector 8-10 through regulation rate computers 5-7. After correction responding to a process amount, e.g. a main steam pressure, a preheat steam pressure, is made by the correctors 8-10, an output signal after correction is outputted to multipliers 11-13. A load command from a load command setter 1 is multiplied thereby, and by means of the obtained command signal, a main stop valve, a regulating valve, and an intercept valve are controlled. This constitution causes proportioning of a forced restoring amount of a speed when a speed change is produced to a load command.
