Abstract
PURPOSE: To control a centrifuge always satisfactorily by prohibiting the inputting of the signals corresponding to measured quatities as a control input signal when said signals change transiently by the effect of electrical noises.
CONSTITUTION: A synchronous signal generating circuit 6 generates a synchronous signal (e) synchronized with the frequency of an electric power source and differentiating circuits 13W15 generte differentiation signals and applies a differentiation signal (d) to a strobe generating circuit 17 via an OR gate 16 when driving signals (a)W(c) change. The circuit 17 is reset by the signal (d) and when the two clock signals (e) are applied thereto, it is set. When the circuit 17 is reset, the output signal (f) thereof prohibits detecting circuits 21W23 to receive the outputs of respectively corresponding detectors 18W20. When the circuit 17 is set, said circuits receive said outputs in accordance with the output signal (f) of that time. Therefore, when any of a motor 2, a vacuum pump 3, a cooler and a heater 4 starts, the outputs of the respective detectors are not inputted to the control circuit during one cycle of the power source frequency 1.
