Title: Oscillation circuit for flowmeter
Inventor: YOSHIKURA HIROSHI
IPC: G01F1/32
Filed: 1992-07-17
Abstract: PURPOSE:To obtain an oscillation circuit for flowmeters which can perform pertinent self-excitation oscillation by using a ceramic vibrating element as an ultrasonic vibrating element. CONSTITUTION:A resistor 15 for feedback and capacitor 20 for feedback are connected in parallel between the in-phase input terminal 11b and output terminal 11c of an operational amplifier 11. Since the capacitor 20 is connected in parallel with the resistor 15, the phase lag quantity of the output signal of the title oscillation circuit caused by an ultrasonic vibrating element 4 for transmission is canceled by means of the capacitor 20 at a frequency near a resonance point fs and the output signal of the oscillation circuit is inverted in phase. Therefore, even when a ceramic vibrator having a small Q-value is used as the element 5, the element 5 can make self-excitation oscillation at the frequency near the resonance point fs in an induced component area M and a high transmitting efficiency can be obtained.

Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a voltage auxiliary circuit which can compensate abrupt variation in internal source voltage and a semiconductor integrated circuit device which includes the voltage auxiliary circuit. SOLUTION: This semiconductor integrated circuit device includes an internal step-down circuit 900 and the voltage auxiliary circuit 100. The internal step- down circuit 900 outputs the internal source voltage Vout. The voltage auxiliary circuit 100 includes a comparator 7, a capacitor 8, transistors 3, 4, and 9, and a constant-current source 1. If the voltage (Vout) at a node Z0 drops abruptly, the potential at the positive input of the comparator 7 drops because of the capacitor 8, so the transistor 9 is turned on. Consequently, the node Z0 is charged. The potential at the positive input of the comparator 7, on the other hand, is charged by the transistor 4, so the transistor 9 is turned off. Consequently, the charging of the node Z0 is completed.
