Filed: 1993-11-29
Abstract: PURPOSE:To prevent occurrence of malfunction due to noise by selecting an output potential of a constant voltage generating circuit so as to set optionally a threshold potential of the input buffer circuit. CONSTITUTION:This input buffer circuit has a load resistor R1 whose one terminal connects to a 1st power supply wire VCC, an N-channel MOS transistor(TR) 10 whose source is used for an input terminal, whose drain connects to the other terminal of the load resistor R1 and used for an output terminal and a constant voltage generating circuit 12 whose potential output terminal connects to a gate of the N-channel MOS TR10. Thus, a threshold potential is optionally selected. That is, the threshold potential VTT=VG-VT of the input buffer circuit is selected optionally without being limited by a threshold voltage VT of the N-channel MOS TR10 by selecting an output potential VG of the constant voltage generating circuit 12. Thus, malfunction due to noise is prevented.

Title: Vibration type transducer
Inventor: YOSHIDA TAKASHI
IPC: G01L9/00
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To eliminate a measurement error when measuring a physical quantity such as distortion by converting the AC change of a drain current into a voltage change and retaining the DC potential of a drain constantly. SOLUTION: A drain current ID outputted from a vibration type sensor 19 is converted into a voltage signal Vd3 by a current/voltage conversion circuit 25 and is outputted to a gain variable circuit 26. Then, the gain variable circuit 26 controls the level of the voltage signal Vd3 to a specific value and outputs a voltage signal VDD to the output terminal. The signal VDD is phase-shifted by 90 degrees using a phase shifter 27 and is subjected to positive feedback to a sensor 19, thus continuing a self-excited oscillation.  In this case, the input terminal of the current/voltage conversion circuit 25 is retained so that it reaches a constant voltage Vr by a stabilization power supply circuit 28, thus preventing a resonance frequency to change even if an electrostatic attraction force changes statistically and eliminating a factor for causing a measurement error when the physical quantity such as distortion is measured and hence achieving an accurate and stable measurement.

IPC: H01S5/068
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To improve the quality of transmission by comparing the output level from a level-at-extinction detector with the output level of a level-at-light- emission detector, and controlling the bias current of a laser diode, so as to keep the difference constant. SOLUTION: The monitor current from a photodiode PD for monitoring the light emission level of a laser diode LD is converted into voltage by an IV-converting circuit C. By this converted voltage signal, the peak level at light emission of a laser diode LD is detected by a level-at-light-emission detector E. Moreover, a level-at-extinction detector D detects the level at extinction of the laser diode LD by the converted voltage signal. Then, a bias current controller G compares the output level of the level-at-extinction detector D with that of the level-at-light-emission detector E and controls the bias current of a laser diode, so as to keep the difference constant. Accordingly, the optical output power can be kept constant.
