Title: Amplifier and compensating circuit of semiconductor pressure sensor
Inventor: ITO TATSUYA
IPC: G01L19/04
Filed: 1991-12-11
Abstract: PURPOSE:To make it possible to apply this circuit in an integrated pressure sensor by setting the temperature characteristic of the offset voltage of an operation amplifier in response to the temperature characteristic of a semiconductor pressure sensor element, and compensating for the temperature characteristic of the sensor element without a high-value resistor. CONSTITUTION:A transistor Q6 and a resistor R2 are provided in an operation amplifier. The ratio of the currents flowing through input transistors Q1 and Q2 of an input-stage differential amplifier circuit is changed at this part. Thus, the difference is intentionally generated between a voltage VBE1' and a voltage VBE2' between the bases and emitters of the transistors Q1 and Q2. The offset- voltage-temperature drift is generated in the operation amplifier. The offset- voltage-temperature drift of the operation amplifier is generated so as to compensate for the temperature characteristic of the output of the sensor element. Thus, the compensation of the temperature characteristic of the sensor element as a whole can be performed. Therefore, a high-value resistor for zero-point compensation is not required, and the application in integrated pressure sensors can be possible.

Abstract: PURPOSE:To achieve energy saving operation of a pump without a troublesome switching operation by a method wherein a pump for a bubbling bath is started in response to a water level sharp rise signal of a water level sensor, and is stopped in response to a water level sharp drop signal. CONSTITUTION:A jet stream apparatus 4 is located outside a bathtub 1 and equipped with a pressure sensor 5 as a water level sensor, a pump 6 and a controller 7. The controller 7 includes, for example, a water level judgment element 13, an arithmetic element 14, a water level sharp change judgment element 15 and a signal output element 16. The water level sharp change judgment element 15 compares the calculated value given by the arithmetic element 14 with a reference value, and when the calculated value becomes equal to the reference value or higher, it is judged as a sharp increase in the water level and a water level sharp rise signal is input to the signal output element 16. And, when the calculated value drops below the reference value, it is judged as a sharp drop of water level, and a water level sharp drop signal is input to the signal output element 16. When receiving the water level sharp rise signal from the water level sharp change judgment element 15, the signal output element 16 outputs an on-signal, and when receiving the water level sharp drop signal, it outputs an off-signal.
