Patent JP-H1133107-A (JP)
Title: Indwelling catheter
Inventor: TAKAHASHI TORU
IPC: A61L29/00
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To prevent a vascular injury and to enable a catheter to be left in a human body for a long period and to improve durability and safe thereof by forming a polyol from a polyurethane resin consisting of a polycarbonate, etc. SOLUTION: A polyol for this indwelling catheter is constituted of a polyurethane resin prepared from a polycarbonate, an isocyanate, and a chain extender. The hardness of the catheter is preferably in a range of Shore hardness A between about 50-D80. When the hardness is lower than the range, the catheter is too soft to be easily handled, and when higher, the catheter may cause danger of a tissue injury. A metal and a compound presenting X-ray impermeability, for instance gold, etc., are added as X-ray contrast agent to give the polyol X-ray impermeability to enable X-ray imaging. This constitution improves kinking resistance and, even when the catheter is folded at 180 deg., drip fusion is not stopped. The strength is not lowered in a severe aging test. Further, the catheter matches a safety test and a tube durability test.

Title: Displacement detector
Inventor: IWAMOTO KIYOTAKE
IPC: G01H1/00
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To detect even a minute displacement and vibration simply. SOLUTION: A piezoelectric vibrator 3 is stuck to one surface of a conductive vibrating plate 5, and an electromechanical conversion part member 1 is formed. A cup-shaped shell member 11 is superposed on and fixed to the other surface of the conductive vibrating plate 5 so as to cover the conductive vibrating plate 5. A closed hollow part 13 is formed inside the shell member 11. A small steel ball 15 is contained in the hollow part 13. When the shell member 11 is displaced by the transmission of shocks through the detector itself and by the lateral, vertical, slant, or turning movement of the detector itself, the steel ball 15 rolls on the inner surface of the hollow part 13. The vibrating sound is generated when the steel ball 15 rolls.  The vibrating sound is transferred to the conductive vibrating plate 5 through the shell member 11, and the electric signal converted by the piezoelectric vibrator 3 is outputted.

IPC: H01L21/302
Filed: 1983-10-19
Abstract: PURPOSE:To control an ion energy and distribution thereof, the distribution of electron temperature and the quantity and kinds of radicals by periodically modulating high-frequency voltage generating plasma. CONSTITUTION:In a plasma treater used for manufacturing a semiconductor device such as an electron cyclotron resonance type plasma treater, a signal from a standard signal generator 44 is modulated by an AM modulator 45 according to a signal from a modulating signal generator 46, and transmitted over a wave guide 48 through an amplifier 47. Modulated microwaves are introduced to the wave guide 48, and enter to a treating chamber 50. Magnetic-field generating coils 49, 51 are mounted around the treating chamber 50, and plasma is generated by the resonance of electrons by a magnetic field and microwaves. Accordingly, since electronic energy is related to the intensity of inputted microwaves, the distribution of electron temperature can be controlled by modulation, and the kinds and quantity of ion radicals generated with the control of the distribution of electron temperature can be controlled.

Filed: 1981-12-01
Abstract: PURPOSE:To prevent damage of a shaft seal by disposing the shaft seal at a sliding portion between a cylinder and a rod in a spaced relationship with each other and providing an oil chamber filled with grease between both shaft seals. CONSTITUTION:A first shaft seal 7 and a second shaft seal 11 are provided at the sliding portion between the cylinder 1 and the rod 3, and an oil chamber 12 filled with grease 13 is provided between both shaft seals by encircling the rod 3. The first shaft seal 7 is provided with the oil chamber 12 filled with grease 13 on the side of a space portion 8, and hence even when the rod 3 moves in any direction, the rod 3 is not damaged due to the oil run-out. Further, the second shaft seal 11 can lower the contact surface pressure since the oil chamber 12 is of a low pressure. Therefore, even if dust adheres to the device or run- out of oil occurs, the rod 3 is not damaged, while even if the damage occurs, the high pressure oil does not leak. Accordingly, it is possible to obtain a shaft seal of high reliability.

Title: Diversity receiver and synthetic diversity method
Inventor: HANADA MIKIFUMI
IPC: H04B7/02
Filed: 1998-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of communication quality even when abnormality is caused in a reception system. SOLUTION: In this diversity receiver for synthesizing reception data D1-D4 from the plural reception systems by weight indicated by weighting signals W1-W4, when an error rate detection part 35 detects that the frame error rate of one of the reception data D1-D4 is more than a fixed rate, a diversity preprocessing part 30 judges that the reception system whose ratio to the one of the maximum value among the weighting signals is less than the fixed rate is a fault and turns the weighting signal of the reception system to '0'. Thus, the reception data including noise of the fault reception system are not used at the time of synthesis and the degradation of the communication quality does not occur.

Abstract: PURPOSE:To prevent a rubber impeller, a front cover and a wear plate from being damaged due to deformation of the blade part during curving, by making the width of the blade part between both side ends thereof on the compression side less than the width thereof between both side ends on the expansion side. CONSTITUTION:A rubber impeller 10 is formed in a cylindrical shape, having its outer surface attached thereto with a plurality of blade parts 2 of a substantially steering wheel-like cross-sectioned shape. During operation of a pump, when a discharge pressure acts upon on the compressing side 17 of the blade part 2, compression deformation occurs due to slidably contact between the blade part 2 and the inner surface of a casing, both side ends of the compression side 17 of the blade part 2 are liable to bulge out. However, since the blade part has curved parts having radius R of curvature in both side end parts so that the width of the compression side 17 between both side ends is less than that of the extension side 18 between both side ends, both side ends of the blade part does not substantially bulges out, thereby it is possible to prevent the blade part 2 itself, a front cover and a wear plate from being damaged.

Abstract: PURPOSE:To confirm the shape of piping route by inserting a thermoplastic element wire into the piping route, feeding electricity to the material and softening it, and stopping the electric feeding and cooling and caking the material to store the shape of the piping route. CONSTITUTION:A survey tool (a) consists of the thermoplastic element wire 1 which covers an electric heater wire 2 internally and belt steel materials 3 and 3' between which the wire 1 is sandwiched from both sides. The survey tool (a) is led in the piping route 4 to be surveyed first and lead wires 9 from a power source 8 are connected to both ends of the wire 2 to feed electricity and cause heat generation. Then the element wire 1 is heated from inside and softens.

Title: Sealing glass composition
Inventor: YABUKI TAKAYOSHI
IPC: C03C8/24
Filed: 1984-09-21
Abstract: PURPOSE:To execute sealing of ceramic package inexpensively in N2 atmosphere by using a sealing glass compsn. obtd. by adding Ni2O3 or PrO2 to a PbO-B2O3 glass. CONSTITUTION:A sealing glass compsn. is prepd. by adding Ni2O3 or PrO2 to a PbO-B2O3 glass. The compsn. is admixed with an org. binder and an org. solvent, kneaded, and coated on a ceramic cap which has been glazed. The product is then sealed in N2 atmosphere at a specified temp. under pressure. Since in this stage, O2 is generated from the compsn., the wettability to ceramics is improved by eliminating residual org. matter and carbon which have been adsorbed before the glazing stage and eliminating foaming of the glass. By this method, a base metal becomes useful in a metallizing part of the ceramic package and the ceramic package is made inexpensive.
