Abstract: PURPOSE:To always effectively set synchronization of an induction motor by accurately predicting the synchronizing timing from the frequency of the induced voltage of an induction motor. CONSTITUTION:After a power source is instantaneously interrupted, a controller 4 is reset, and the main switching element of a main circuit 1 remains OFF. When the power source is recovered and a phase signal P is input, a frequency measuring circuit 5 starts predicting the frequency. The controller 4 accurately measures the period J continuously by the measuring circuit 5, thereby calculating so as to generate a correction signal C when the predicted calculation of the frequency is obtained. Thus, the signal (e) of the frequency in response to the rotating speed signal (d) and the rotating speed signal (d) are corrected by the signal C, a control signal (g) corresponding to the output of the frequency is generated, and supplied to the main circuit 1.

Title: Waveform shaping circuit
Inventor: SUGIURA KENJI
IPC: G06K7/00
Filed: 1983-11-14
Abstract: PURPOSE:To output only a correct signal without having any influence of noise by forming an output pulse signal at the timing of rise of output of the first comparator and the timing of fall of output of the second comparator. CONSTITUTION:Even when the outputs of comparators 9 and 10 contain noise components of an input signal, the noise components are not outputted because the pulse signals outputted finally from a signal output terminal 14 are formed by the timing of rise of output of the first comparator 9 and that of fall of output of the second comparator 10. Because two thresholds are provided by respective potentiometers 7 and 8 according to the input signal envelop, the duty of the pulse signal to be outputted is nearly the same as the provided one even through the input signal varies in level.
