Patent JP-H06249688-A (JP)
Title: Electromagnetic flowmeter
Inventor: TORIMARU TAKASHI
IPC: G01F1/60
Filed: 1993-02-24
Abstract: PURPOSE:To obtain a stable output by an exciting means which uses an exciting frequency at a specific high frequency and by a smoothing means. CONSTITUTION:An exciting circuit 40 receives a control signal Vc0 and it supples to the exciting coils 33, 34 a square-wave exciting current If which is provided with a steady value at a binary value or higher and which is changed to be positive and negative. The circuit 40 supplies to the coils 33, 34 the current If whose exciting frequency has been fixed to be a frequency band between an upper-limit change frequency value in a frequency group at an integral multiple of a commercial frequency at 50Hz and a lower-limit change frequency value in a frequency group at an integral multiple of 60Hz, as a commercial frequency, which is higher than 50Hz. A sampling circuit 41 samples the output signal of a differential amplifier 39 in a state that the current If has been set to the steady value, it outputs the signal to a changeover circuit 42, it changes over a noninversion and an inversion so as to correspond to the positive state and the negative state of the current If, and it outputs the signal to a smoothing circuit 43. Thereby, a flow-rate signal is obtained. When the exciting frequency at such a high frequency is used, an effective smoothing operation can be expected by a smoothing means. As a result, even when a noise is mixed with a signal voltage, a stable output can be obtained.

Filed: 1985-02-26
Abstract: PURPOSE:To suppress the sudden change of a control signal by comparing the deviation between a reference waveform and an input signal with the prescribed fixed value through a comparing/discriminating circuit and delivering the value decided by said reference waveform when the deviation exceeds a fixed level. CONSTITUTION:A shock preventing circuit suppresses the sudden change of the error voltage (input signal) SI to obtain an output signal SO and delivers this signal SO to a rotary device which turns a rotary barrel. Here the shock preventing circuit consists of a reference pattern generating circuit 76, a comparing/discriminating circuit 71 and a signal switch circuit 73. The circuit 76 produces a reference waveform signal SA following the signal SI through the 1st comparator 70 and an integrator 74 and detects the deviation between the signal SA and the signal SI to deliver it to an absolute value circuit 77 and a deviation setting unit 78. When this deviation exceeds a fixed level, the value obtained from the signal SA is delivered as the signal SO. While the signal SI is delivered as it is when said deviation is less than the fixed level.
