Abstract

PURPOSE:To enable to disconnect and reclosing of arbitrary oscillator while operating the invertor, by constituting the part contributing to the disconnection and reclosing with the switch and timer. CONSTITUTION:The oscillation circuit 1B consists of the oscillator 11, frequency divider 12, monostable multivibrator 13, line driver 16 feeding the output to the common bus, line receiver 17 receiving the pulse on the common bus, and monostable multivibrator 14. When disconnecting the oscillation circuit 1B, after disconnecting the switches 105A and 105B, the switch 104 is opened. Since the pulse of frequency standard is fed from the oscillation circuit 2B, disconnection is enabled while operating the invertors 1 to 3. Further, in reclosing the oscillation circuit 1B, first the switch 104 is closed and the power supply 31 is connected to the buffer circuit 101. After a given time T41, when the switches 105A and B are closed, the output of the timer 102 changes from 0 to 1 after a given time T42 to open the AND circuit 13. Since the frequency divider 12 is compulsively synchronized with the signal (a), the reclosing is possible while operating the inverters 1 to 3.
