摘要： This invention aims at providing a novel semiconductor accelerometer comprising a smaller number of substrates and a production method thereof.An insulating film is formed on a main plane of a P-type silicon substrate, and a beam-like movable electrode is formed on the insulating film. Fixed electrodes are then formed on both sides of the movable electrode in self-alignment with the movable electrode by diffusing an impurity into the P-type silicon substrate, and the insulating film below the movable electrode is etched and removed. There is thus produced a semiconductor accelerometer comprising the P-type silicon substrate 1, the movable electrode 4 having the beam structure and disposed above the P-type silicon substrate 1 with a predetermined gap between them, and the fixed electrodes 8, 9 consisting of the impurity diffusion layer and formed on both sides of the movable electrode 4 on the P-type silicon substrate 1 in self-alignment with the movable electrode 4. This sensor can detect acceleration from the change (increase/decrease) of a current between the fixed electrodes 8 and 9 resulting from the displacement of the movable electrode 4 due to acceleration.

摘要： A liquid quantity detecting device includes a float-type liquid-quantity meter and a torsion bar-type liquid meter. In the float-type liquid-quantity meter, the liquid quantity is detected by a float in a tank and the position of the float is converted to an electric signal by a variable resistor. The torsion bar-type liquid meter includes housings fixed to the tank, torsion bars, one end of each being fixed to the tank by the housings and the other end of each being fixed to a supporting member so that the torsion bars are twisted by weight of the tank, twisted angle detection means for detecting the twisted angle of the torsion bars, and an electrical processor for supplying a signal corresponding to the quantity of liquid in the tank after receiving a signal from the twisted angle detector. When the liquid quantity in the tank is larger than a predetermined quantity, the liquid quantity, for example, the quantity of gasoline in a gasoline tank, is measured by the floating-type liquid-quantity meter. When the liquid quantity in the tank is smaller than a predetermined quantity, the liquid quantity is displayed precisely and accurately by the torsion bar-type liquid meter.
