Title: Analog switch circuit
Inventor: TOMIKAWA TOSHIO
IPC: H03K17/687
Filed: 1985-08-09
Abstract: PURPOSE:To remove the influence of the amplitude of an analog signal inputted to an input terminal by holding the voltage between the gate and source of an analog switch constant. CONSTITUTION:When the time constant determined by the product of the value of a resistance 14 and the value of a coupling capacitor 13 is set large enough to allow an AC signal appearing at a load terminal 52 to pass, the AC signal is impressed to an uninverted input terminal 54 without attenuating. Further, a DC component is supplied from an on power source 9 and applied to the uninverted input terminal 54 as it is. Therefore, those two voltages are impressed to the uninverted input terminal 54 of over the other and the superposition voltage V1 appears at an output terminal 53. The gate-source voltage VGS of the analog switch 1 is constant without reference to the voltage of the AC signal appearing at the load terminal 52. Thus, the voltage VGS becomes constant, so the on resistance of the analog switch 1 is not modulated with the AC signal and the AC signal supplied to a load 2 is never distorted.

There is not special restriction in both the method for generating fine bubbles by the pressure-reducing processing of the gas dissolution water and the method for contacting the fine bubbles with the object to be cleaned 5. For example, the gas dissolved water, where the gas amounts not smaller than their saturated dissolved amounts at the atmospheric pressure are dissolved under conditions of their specific increased pressures, is sent to a closest nozzle 13 to a cleaning portion, while keeping their pressures increase.  Then, by releasing it at the opening portion of the nozzle 13 the state of the gas dissolved water from the increased gas-pressures to the atmospheric pressure, the fine bubbles are generated therein to make them come into contact with the object to be cleaned 5.

Filed: 1988-07-13
Abstract: PURPOSE:To make a motor highly efficient and to allow it to be driven at a high speed by integrally jointing a laminate type piezoelectric element to a plurality of projected sections resonating approximately right beside its moving direction. CONSTITUTION:An ultrasonic motor with laminate type piezoelectric elements 4 as its driving source integrally joints resonant bodies 3 to the movable tip of the piezoelectric elements 4. These resonant bodies 3 form a plurality of tabular projected sections 3a approximately right beside the moving directions of the piezoelectric elements 4 and are constituted so that the natural frequency of their lateral deflection will resonate with the moving frequency of the piezoelectric elements 4. The tip of this projected section 3a is arranged in the outside circumferential region of a rotating drum 1 integrated with a shaft 2, to which an angle theta and clearance 8 as required are given so that the rotating drum 1 may be pressed with the above lateral deflectional oscillation to rotate in one-way. Thus, the moving stroke is amplified by the length effect and since the natural frequency as above-mentioned resonates with the driving frequency of piezoelectric elements 4, it is further so amplified that larger stroke, higher frequency and higher pressure will rotate the rotating drum 1 from the tip of the projected sections 3a.
