Title: Moving distance sensor
Inventor: HINO MASAMICHI
IPC: G01B7/00
Filed: 1984-05-25
Abstract: PURPOSE:To measure the moving distance of a movement detecting member or an object which is to be measured and is coupled thereto always with good accuracy and high resolving power by detecting the change of the restoring force of a spring by means of a lod cell and measuring the moving distance of said member or object. CONSTITUTION:The load cell 11 is constituted with a straight gage and detects the stress to be exerted thereto in the vertical direction. The detection signal is supplied via a lead wire 14 to a detecting circuit (not shown). The restoring force F=kx is generated by the contraction of a spring 12 (spring constant k) by (x) and is applied to the cell 11 if it is assumed here that a movement detecting rod 13 moves by (x) from the state shown in the figure. The cell 11 generates the signal proportional to the force exerted thereto and therefore the determination of (x) is made possible by said signal. The moving distance is thus measured always with good accuracy and high resolving power.

Title: Mamufacture of semiconductor device
Inventor: TAKASAKI KANETAKE
IPC: H01L21/314
Filed: 1980-07-31
Abstract: PURPOSE: To apply fine and high accuracy thermal treatment, by covering a semiconductor surface having a wiring electrode with a protective insulating film, and irradiating high energy beams at the surface.  
     CONSTITUTION: An FET field oxide film 2 is made by direct oxidization at high temperatures and composed of minute SiO 2 . Meanwhile, an SiO 2  film 6 at the uppermost layer is formed on an Al wiring 4 by resolving reaction of SiO 4 . The film 6 is formed at low temperatures, therefore H 2  is hard to fall out and the porous film 6 is formed. Therefore, with beams irradiated at the film 6 by scanning a CO 2  gas laser, H 2  in the film 6 is evaporated and removed and a minute film is obtained. In this way, the whole part of the SiO 2  film with a thickness of 1μm is heated to 600°C or higher to remove most of the H 2 . As the heating is instantaneous, the Al wiring 4 will not be dissolved and a fine and high accuracy device can be obtained. Si 3 N 4  also includes much H 2  and becomes porous one through growth by a plasma CVD method. Therefore, the protective film becomes a good one by treating in the same way.

As a result, a block 19 is moved, and a gap g3 is expanded up to 100mu and balanced. The value which is the sum of 100mu and the thickness of non-magnetic film 21 is indicated. Thus the film thickness (d) is measured without contact.

IPC: H01S3/03
Filed: 1992-04-24
Abstract: PURPOSE:To establish a gas laser tube fixing method corresponding to thermal expanstion of a gas laser tube during operation and improve a laser output at the time of starting discharge. CONSTITUTION:A gas laser tube 11 is supported in such a manner as not allowing at least one supporting portion among two or more supporting portions to be moved from a mount base 17. The other supporting portions are supported by holders 12, 13, 14, a front and rear slidable holder 31 using an insulating material and a mount base 32 for slide. Corresponding to front and rear elongation of a gas laser tube itself during operation due to thermal expansion, a slide type holder 31 moves in the front and rear sides. Thereby, stress of gas laser tube due to thermal expansion and deviation of mirror angle due to such stress can be prevented. Accordingly, the mirror angle immediately after initiation of discharge and after thermal stabilization become almost equal and thereby a laser output at the time of starting discharge can be improved remarkably.

Abstract: PURPOSE:To improve the linearity of a photoelectric conversion and an S/N ratio by providing a photodiode connected between the input terminals of two current/voltage converters, an inverting amplifier for inverting the polarity of the output signal of one of the current/voltage converters and the like. CONSTITUTION:The output current of a photodiode 1 is inputted to operational amplifiers 2 and 3 as signals with the same values and different polarities. The amplifier 3 constitutes a current/voltage converter together with a resistor R2 and a capacitor C1 and takes out only DC components at a time constant tau2 represented by tau2=R2.C1 to output them. An operational amplifier 4 constitutes an inverting amplifier together with resistors R3 and R4 and outputs a signal with polarity inverted from that of an input signal. When amplification degrees by the amplifiers 3 and 4 are G2 and G3, respectively, and the value of a resistor element R5 connected between the amplifiers 4 and 2 is determined by R5=G2.G3, the DC components of the output current of the diode 1 are canceled at the input terminal of the amplifier 2 and it amplifies only the AC components to output them. Therefore, so far as the output of the amplifier 3 is not saturated, the amplification degree of the amplifier 2 can be set to 10-100 times the amplification degree G2.
