Title: Displacement origin detector
Inventor: FUJII KATSUHIRO
IPC: G01D5/36
Filed: 1993-06-21
Abstract: PURPOSE:To prevent the vanishment or erroneous occurrence of an origin signal by comparing means of first, second elements with a reference level, and outputting the signal according to an intersection of outputs of the first, second elements. CONSTITUTION:When a scale is moved, photoreceivers 3, 4, 5 receive lights reflected on reflecting surfaces 1A, 1B, 1C and output photoelectric currents. These outputs are converted into voltages by I/V conversion amplifiers 11a, 11b, 11c, and output. Since the photoreceivers 3, 4, 5 photoreceive most of the reflected lights of the scale, a reference level Vr of an output of a reference level forming circuit 14 in which a predetermined ratio Rb/Ra is multiplied by its sum signal becomes a substantially constant potential. A mean signal Vm of the photoreceivers 3, 4 is compared with the voltage Vr by a comparator 13, and it is so controlled 'as to operate a pulse generator 15 only when a condition of Vm>Vr is satisfied. Thus, the generator 15 stably generates an origin signal at rise and fall of the output of the comparator 12 at the intersection of the outputs of the photoreceivers 3, 4.

Title: Electromagnetic flowmeter
Inventor: KUROMORI KENICHI
IPC: G01F1/60
Filed: 1989-07-05
Abstract: PURPOSE:To reduce the power consumption by detecting the variation rate of a flow rate and varying an excitation frequency according to the detected value. CONSTITUTION:A signal variation rate circuit 21 calculates the variation of a flow rate signal VQ and outputs a variation rate signal VC. Then a rectifying circuit 22 rectifies this signal VC on a full-wave basis and outputs a rectified signal VCR to a voltage/frequency converting circuit 23. Then the circuit 23 converts the signal into a frequency signal VCF corresponding to the signal VCR and outputs it to an excitation timing circuit 15. This circuit 15 outputs a timing signal S1 synchronized with the signal VCF to an exciting circuit 18 and the signal becomes an exciting current of corresponding frequency. Thus, the excitation frequency is selected automatically according to the extent of variation of the flow rate signal. Further, when the flow rate variation is extremely small, the signal VQ has little variation. Therefore, the signal VC is nearly zero and the value of the signal VCR is also nearly zero. The exciting current flows only intermittently in a pulse shape and large power-saving effect is obtained.

Filed: 1988-07-13
Abstract: PURPOSE:To make a peak hold signal follow an input signal precisely by setting the peak hold signal at a direct-current potential in a reset state and by diminishing a difference potential from a peak hold input potential. CONSTITUTION:During a period when a reset signal (a) is at a high potential (a potential enough to turn ON a transistor Tr 4 sufficiently), the collector of the Tr 4 is kept at a potential being equal to a direct-current potential Vb to which the base thereof is connected. A capacitor 3 is charged or discharged so that the potential of an input terminal of an emitter follower circuit 5 connected to the collector of the Tr 4 be in accord with the potential Vb, and an output signal (c) is kept at the potential Vb irrespective of an input signal (b), as shown by a broken line. When the signal (a) changes to be at a low potential from this state, the Tr 4 turns OFF, and a potential at the node of a diode 2 and the capacitor 3 turns to be a value according with the signal (b) since the capacitor 3 is charged when the signal (b) changes to a value larger than the one of the preceding potential. By this constitution, a peak hold signal is made to follow the signal (b) precisely.
