Title: Optical path changeover device
Inventor: ONO ATSUSHI
IPC: H04B10/03
Filed: 1990-03-08
Abstract: PURPOSE:To prevent out of synchronism at changeover of an optical path and generation of momentary interrupt by monitoring synchronizing information of a transmission light of an optical fiber communication line and sending a transmission light synchronously with the information from a communication equipment to the optical fiber communication line. CONSTITUTION:When a communication equipment 22 is inactive, a control signal to an optical switch 23 is logical 0 and a transmission light from an input side optical fiber communication line 20 is sent as it is to an output side optical fiber communication line 24 via a photocoupler 2 and an optical switch 23 sequentially. When the communication equipment 22 is active, the transmission light from a photocoupler 21 is monitored and an output transmission light given to the optical switch 23 synchronously with the light is formed and a prescribed control signal is given to the optical switch 23 to give the transmission light to an output optical fiber communication line 24. When the communication equipment 22 is again inactive, the transmission light from the optical fiber communication line 20 is sent as it is to the optical fiber communication line 24 via the photocoupler 21 and the optical switch 23 sequentially. Thus, the momentary interruption or out of synchronism in the transmission signal at changeover of the optical path is prevented.

Abstract: PURPOSE:To prevent the size of a pump unit from increasing by serial- connecting and operating a motor pump through commercial power driving and a motor pump which can be variably-operated with a frequency converter for corresponding to the operation of both the motor pumps according to a small, medium and large amount of water. CONSTITUTION:This pump unit is constituted by serial-connecting a motor pump A through commercial power driving and a motor pump B which can be variably-operated with a frequency converter 50. The motor pumps A, B are full circumference flow type motor pumps of the same structure, and the suction 4a of the motor pump A and the suction 3a of the motor pump B are connected with each other through flanges 53, 54. In the case of a small amount of water, the motor pump B is operated independently at a prescribed speed with the frequency converter 50. In the case of a medium amount of water, the motor pump A is operated independently. In the case of a large amount of water, the motor pump A is always operated and the motor pump B is operated at a prescribed speed. It is thus possible to provide operation control without any uselessness and reduce the size of a pump body.

IPC: H03K17/04
Filed: 1983-03-29
Abstract: PURPOSE:To offer a power transistor driving circuit with less driving power, ease of high frequency switching and high dielectric strength and less power loss by the constitution that a main power transistor (TR) is switched by switching a sub-TR. CONSTITUTION:The main TRQ1 is driven by a signal e1 having a period tau1 and a conduction time of tau2. A signal e2 comprising a pulse train having a pulse width of tau4 sufficiently smaller than the tau1 and a period of 3 is inputted to a base of a TRQ3 independently of the e1. The Q3 is turned on during the period of tau4 and turned off during the period of (tau3-tau4). since the Q2 is turned on by the e1 when the Q3 is turned off, a base current IB1 flows to the Q1 and is conductive. When the Q3 is turned on after a time of (tau3-tau4), the base current IB1 applied to the Q1 flows continuously by the operation of a D6 and L1 as shown in Fig. C and so long as the e1 is applied to the Q2, the Q1 continues the conducting state. When the e1 is interrupted at a time T1, the Q2 is cut off, the base current of the Q1 is also cut off, and the emitter of the Q1 is opened momentarily also.
