Filed: 1984-05-18
Abstract: PURPOSE:To obtain a preferable contact in an ultrafine region and to flatten the contacting portion by selectively growing a component which forms a semiconductor substrate in a contacting hole, and burying the hole with the grown layer. CONSTITUTION:A contacting hole is formed at an insulator film 2 on an Si substrate 1. Then, metal or semiconductor film 4 is accumulated. Subsequently, when it is disposed in atmosphere which contains components for forming the substrate 1, Si of the component is dissolved in the film 4. The Si dissolved in the film 4 is grown in the boundary contacted with the film 8 and the substrate 1 to form an Si grown layer 5. As a result, the layer 5 can be grown to become the same thickness as the film 2, and the surface of the film 4 is flattened in the contacting portion. Then, after a metal film 11 is accumulated, desired wiring pattern is formed on the films 4, 11. According to this method, even if the hole of the contacting portion is opened vertically, preferable contact can be obtained, and preferable contact can be obtained even in an ultrafine region.

Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To specify the migration state of a diabetes patient to diabetic nephritis by detecting the qualitative and quantitative change of heparin sulfuric acid in the urine specimen of the diabetes patient. SOLUTION: In diabetes nephritis, the metabolic abnormality in heparin sulfuric acid being present in a ground film occurs and the qualitative and quantitative change of heparin sulfuric acid occurs in the urine of a patient due to the progress of nephritis. Therefore, by detecting the qualitative and quantitative change in the heparin sulfuric acid in the urine specimen of the diabetes patient, the migration state of the diabetes patient to diabetic nephritis can be specified. The qualitative and quantitative change indicate the change in, for example, the amount of specific heparin sulfuric acid, amount of molecule, and amount of sulfuric acid group where either residual group of the constitution sugar is subjected to some sort of modification.  As a determination method for detecting the qualitative and quantitative change in heparin sulfuric acid, an antigen antibody reaction due to heparin sulfuric acid and antiheparin sulfuric acid antibody in a specimen is used, thus rapidly specifying the migration of the diabetes patient to diabetic nephritis.

Filed: 1980-07-28
Abstract: PURPOSE:To obtain necessary and enough strength of a device and improve its endurance against humidity by putting on an element circuit PSG and Si3N4 in order with thickness of each film being specified. CONSTITUTION:PSG16 (tP in thickness) and Si3N417 (tN in thickness) are laid on an element circuit formed with an SiO2 film 13 and an Al wiring 15 on an Si substrate 10. By said constituion, the PSG will restrain Na<+> ions and so on in SiO2 from wafting with P for stabilizing element property, and Si3N4 will repel water invading from the outside with its minuteness for protecting PSG which is easily affected by water. Further, if the thickness of a film is settled to be within a scope tN+ (1/k)XtP>=1mum(1.5<=k<=2.5), internal strength will improve as well as the endurance against humidity, preventing cracks on PSG and Si3N4 therefore increasing manufacturing efficiency of a device and decreasing cost for it. It is also effective if PSG, amorphous Si (tA in thickness) and Si3N4 are laminated maintaining a relation of tN+tA+(1/k)XtP>=1mum.

Title: Simplified acceleration sensor
Inventor: KISHIMOTO FUMIO
IPC: G01P15/02
Filed: 1995-04-26
Abstract: PURPOSE: To detect acceleration with a simple structue by fitting a weight to be applied with acceleration to a flexible substrate of a piezoelectric element fixed at the peripheral end sections and arranged horizontally. CONSTITUTION: A flexible substrate 3 is horizontally arranged while the peripheral end sections are fixed by the pinching faces 22 protruded on the inner periphery of a casing 2. The flexible substrate 3 is made of a piezoelectric element pinched with a piezoelectric material by two circular electrode plates, and the electric signal is generated on the electrode plates in response to the pressure in the thickness direction. When vertical acceleration is applied to a weight 4, upward or downward force is applied to the weight 4. The flexible substrate 3 is applied with compressive force or tensile force in the thickness direction via a connection section to a rod-like fitting section 5, and an output is generated on the piezoelectric element. The output is amplified by an amplifier 10, and the magnitude of the acceleration corresponding to the value is displayed on an indicator 11.  When horizontal acceleration is applied to the weight 4, the weight 4 is moved in the opposite direction to the acceleration, the flexible substrate 3 is distorted, and an output is likewise generated.

Title: Exposure device
Inventor: TANIMOTO SHOICHI
IPC: H01S3/097
Filed: 1988-04-27
Abstract: PURPOSE:To maintain waveform at a specific value at all times without hastening the consumption of components and gas by oscillating pulse light before the time when variation in the wavelength exceeds a specific range is elapsed in a nonexposure state, and detecting and controlling the wavelength. CONSTITUTION:This exposure device is equipped with the resonator mirrors 1 and 2 of an excimer laser, etalons 3 and 4, a gas chamber 5, a wavelength monitor 12, an exposure control part 10, a wavelength controller 11, a 1st lighting optical system 7, a 2nd lighting system 9, a reticle R, a projection lens L, and a wafer W. Then the pulse light is oscillated intermittently by a light source before the time when the variation in the previously measured wavelength of the pulse light exceeds the constant range is elapsed except in the irradiation period of light to an object, thereby controlling the wavelength to a specific value. Namely, a wavelength detecting means 12 detects the wavelength of the pulse light and the wavelength is controlled to the specific value according to its detection signal. Consequently, a shift in the center of a spectrum due to the thermal deformation, etc., of an optical element during the nonexposure state is prevented to maintain the wavelength at the specific value at all times.

Title: Reinforced steel pipe for burying
Inventor: KURAMOTO TAKAHIRO
IPC: F16L9/08
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To improve displacement resistant stress of a concrete-made protecting layer, and prevent the protecting layer from falling during burying in a propulsive pipe method, by providing the outer layer of the steel pipe with a resin coating layer and placing the concrete-made protecting layer on the resin coating layer through a winding layer of fiber cloth. SOLUTION: A resin coating layer 11 is provided on the surface of a steel pipe 10, and fiber cloth 12 is wound on the resin coating layer 11 and is fixed by adhesive. By placing a concrete-made protecting layer 13 on them, a reinforcing steel for burying is formed. The fiber cloth 12 is produced by forming base structure with synthetic fiber multi-filament threads, and forming cut-pipe (plush fabric) with synthetic fiber mono-filament threads. Thus, because axial shear force is operated between the steel pipe 10 and the protecting layer 13, minimum shearing stress is more than 1 ton/m<2> when the protecting layer 13 dislocate by 5 cm. Therefore, even when a propulsive pipe method is employed to bury the steel pipe, the protecting layer 13 is prevented from dislocating in relation to the steel pipe 10, or separating and falling out.
