Abstract: PURPOSE:To improve the intensity noise suppressing effect by modulating local oscillated laser beam to control the input phase to a photodetector, the gain of the photodetector, the phase of the output signal of the photodetector, etc., so that a modulated signal component included in a reception output signal is minimum. CONSTITUTION:The local oscillated laser beam projected to an optical coupler 1 is modulated by a modulator 4, and the modulated signal component included in the reception output signal is taken out, and inputs to photodetectors 2 and 3 are controlled by optical control elements or the like and gains of photodetectors 2 and 3 and the gain or the phase of an amplifier are controlled by outputs in a control circuit 5 so that the modulated signal component is minimum. Thus, the intensity noise due to the phase difference between the incident light from the optical coupler 1 to the photodetector 2 and that to the photodetector 3, the difference of frequency characteristic between photodetectors 2 and 3, the difference of frequency characteristic of the gain or the like of the amplifier, or the like is automatically suppressed. The variance of characteristics in each part due to secular change, temperature change, or the like is compensated to perform stable coherent optical communication.

Filed: 1984-07-09
Abstract: PURPOSE:To prevent the capacity of pay-out from lowering due to abnormal pay-out speed, and therefore, to aim at stabilizing the pay-out of banknotes, by suitably changing the timing of disengaging a clutch in accordance with the situation (frequency) of occurrence of the abnormal pay-out speed when the latter occurs. CONSTITUTION:A no empty pay-out error counter A8 counts and judges how much degree normal pay-out speed are continued during pay-out of banknotes. When abnormal pay-out speed occurs, a compensating width is suitably selected in accordance with the generation rate of errors with reference to a count value obtained at that time and a previously set pay-out speed error judging reference value A12, and therefore, the turn-off time of a clutch 22 is increased and decreased. Accordingly, when the speed is low, the time of turn-off of the clutch is lengthened to aim at speeding up the pay-out operation, and, thereby the pay-out is made at an optimum feed speed with no errors to carry out a stable pay-out of banknotes.
