Patent JP-H11311209-A (JP)
Title: Linear motion machine
Inventor: NODA MITSUO
IPC: B25J19/00
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To provide a thin (low) linear motion machine retaining rigidity as it is as a linear motion machine. SOLUTION: A guide rail 10 is fixed to a base 1, and a base bottom wall 1a and a rodless cylinder unit 30 are piled in the vertical direction, and a slit 32 is laterally arranged facing to the guide rail 10. Through this constitution, since the rail 10 is integral with the base 1, it is maintained highly rigid, and the slit 32 laterally faces, as a result, an external moving body arranged outside the slit 32 laterally faces, and a slide table is prohibited from piling on a cylinder barrel. Therefore, the thickness of a linear motion machine can be made thin nearly to the thickness in the width direction of the slit of the cylinder barrel of a slit type rodless cylinder.

Title: Spiral electrode
IPC: H01M4/24
Filed: 1992-03-30
Abstract: PURPOSE:To prevent the generation of failure such as break of a negative plate or short circuit at an end of a positive plate by forming the coiling-start ends and the coiling-finish ends of plates thin. CONSTITUTION:In a spiral electrode, which consists of a positive plate 1, a negative plate 3 and a separator 3, the coiling-start end 12 of the positive plate 1 and the coiling-start end 32 of the negative plate 2 are formed thin by a grinder. The coiling-finish end of the positive plate 2 is formed thin similarly. The coiling-start ends of the plates are thereby curved smoothly along the core, and a stage difference at the coiling-finish end of the positive plate is eliminated, and the break of the negative plate by a pressure roller is prevented.

Title: Vehicle position control unit
Inventor: KATAYAMA YOSHIO
IPC: B60T8/32
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To ensure normal vehicle position control by correcting an error of the change in the vehicle slip angle even when the road surface is inclined not only gently but also sharply. SOLUTION: In a vehicle state operation section 8, when a slip angle change speed β' used for determining the start of vehicle oversteering control and calculated using the lateral acceleration Gy detected by the lateral G sensor 7 is corrected when the lateral G sensor 7 mis-detects the lateral acceleration Gy and the mis-detected lateral acceleration Gy is used for calculation. More specifically, if an absolute value of the slip angle change speed calculated by subtracting a low frequency filter value β'- off (n) from the slip angle change speed β' calculated using the lateral acceleration Gy exceeds a predetermined value k3 and becomes equal to or less than a predetermined value k4, the calculated slip angle change speed is corrected.

Inventor: HATANO TSUTOMU
IPC: H01L29/40
Filed: 1984-04-11
Abstract: PURPOSE:To reduce the mutual inductance between heterogenous power wirings, especially in an IC chip, to suppress the fluctuation of potential and an induced current, and to enhance the reliability of the titled device by a method wherein a wiring of the same potential as a semiconductor substrate is provided between the heterogenous power wirings.

The same electric connection is performed between the underlying wiring 18 and a semiconductor substrate 20, thereby enabling to maintain the potential of a wiring 14 at the same potential as the semiconductor substrate 20. The magnetic energy generating from the fluctuation of time of the current of a power source wiring 10 is converted to electric energy and disappears. As a result, the effective mutual inductance between the power source wirings 10 and 11 is reduced by providing the wiring 14 when compared with the case where the wiring 14 is not provided.

Abstract: PURPOSE:To produce a steel product excellent in toughness and having a high hardness carburized layer in the internal part and at the surface in a short time by applying carburizing treatment to a worked product prepared by using, as a stock, a medium carbon steel with specific carbon content to a specific depth from the surface and then applying hardening treatment to the above product to a depth beyond the carburized layer. CONSTITUTION:Carburizing treatment is applied to the part requiring high hardness at the surface of machine parts composed of a medium-carbon structural carbon steel or alloy steel containing 0.30-0.53% C by a gas carburizing method by means of high-frequency heating or by using a pasty carburizing material so that C content is regulated to 0.6-0.9% at a depth of <=0.8mm from the surface. Subsequently, the surface of the above parts is subjected to hardening treatment to a depth beyond the carburizing depth of 0.8mm, by which the machine parts where surface hardness is remarkably improved and no abrupt changes are seen in hardness distribution in the noncarburized tough part in the inner part can be produced by means of short-time carburizing treatment.

Title: Force sensor
Inventor: KATO TOMIO
IPC: G01L1/16
Filed: 1987-03-26
Abstract: PURPOSE:To detect dynamic force and static force with high sensitivity and good response, by mounting switching FET and impedance converting FET. CONSTITUTION:Gas is introduced from an introducing port 3 and the pressure thereof is transmitted to an electrode 17. Whereupon, not only the electrode 17 but also a piezoelectric body 18 are distorted and the internal spontaneous polarization corresponding to the strains of both of them is generated and charge is induced in the electrodes 17, 19 of a piezoelectric element 5 with said polarization. The detection of voltage due to this charge is performed by such a method that a voltage pulse of a predetermined cycle is applied to the gate terminal of switching FET (Tr1) through a terminal 14 to intermittently bring switching FET (Tr1) to a continuity state and detected as the pulse like voltage intermittent between both terminals, that is, the terminals 13, 15 of an output resistor Rs. Since the detected voltage corresponds to the pressure of the gas, the pressure of the applied gas can be known from the magnitude of the detected voltage. By this method, dynamic and static pressures can be detected with high sensitivity and good response.

CONSTITUTION:After a first layer PolySi wiring 3 is formed, an interlayer insulating film 4 of SiO2 or the like and next a second layer PolySi 6 is formed. Thereupon a specific resistance of the second layer PolySi 6 is made small. In succession, the second layer PolySi 6 is coated with a resist 7, and a hole is opened in the resist 7. Next the resist 7 is used as a mask to open a hole in the second layer PolySi 6 and the interlayer insulating film 4 on the first layer PolySi wiring 3. After the resist is then removed by ashing, silicide 8 is formed on the second layer PolySi layer 6. Next a resist pattern is used as a mask to etch the silicide 8 and the second layer PolySi layer 6, so that a second layer PolySi wiring is formed, and then the resist is removed. Since direct contact of the first and second PolySi wirings can be hence realized, the integration density can be improved.

Title: Method for judging corrosive deterioration of two-layer metal wire material
Inventor: SHIMADA TAKEFUMI
IPC: G01N27/90
Filed: 1991-03-11
Abstract: PURPOSE:To judge the corrosive deterioration of a two-layer metal wire material wherein the periphery of a core wire is coated with a different kind of a metal such as a zinc plated steel stranded wire by individually detecting the residual amounts of the core wire and the coating layer after corrosion. CONSTITUTION:When a zinc plated steel stranded wire is subjected to an eddy current flaw detection test, the phase detection output thereof linearly changes on the two-dimensional plane shown by a phase and amplitude in directions respectively different at the time when only a zinc plating layer reduces and at the time when only a steel stranded wire reduces. Therefore, when only the phase component in the direction crossing those straight lines at a right angle is taken out from the output of a detection coil, phase detection is performed in the phase of the direction capable of detecting the volume change of one metal without being affected by the volume change of the other metal to individually detect the residual amounts of the respective metals.
