Title: Direct-current polarization type hydrogen sensor
Inventor: TAKETSU NORIHIKO
IPC: G01N27/416
Filed: 1988-05-17
Abstract: PURPOSE:To enable the rapid, successive and highly-precise measurement of the quantity of hydrogen, by heating a solid electrolyte or a part in the vicinity thereof to be at a specified temperature or above, and by bringing a measuring electrode into contact with a substance to be measured. CONSTITUTION:A sensor element 1 of a probe 30 is put in a substance to be measured, and a heater 41 is operated to heat the element 1 to a temperature of 400 deg.C or above, while a potentiostat 32 is operated to impress a prescribed voltage so that the reference electrode 6 side be positive and the measuring electrode 6 side negative. In the initial period of impression of the voltage, an ion current flows due to hydrogen ions located inside the reference electrode 6 and contained in a hydrogen ion conductive solid electrolyte 2, and this ion current is observed by means of an ammeter 31. Since the reference electrode 6 is shielded from the outside by a sealing material 11 and a supporting material 3, however, migration of the hydrogen ions disappears after a prescribed time passes, and a certain electron current flows through the solid electrolyte 2. By measuring this electron current by means of an ammeter 31, the partial pressure of hydrogen in the substance to be measured can be determined.

Title: Low noise vehicle
Inventor: KIMURA AKIYOSHI
IPC: F16F9/46
Filed: 1979-09-18
Abstract: PURPOSE: To improve controlling property of a controller over a wide range of running condition of an engine by changing damping characteristics of the controller corresponding to the running condition of the engine.  
     CONSTITUTION: While an engine 24 is supported on a car body by resilient mount members 25, the upper portion of the engine is connected to a car body panel 23 through a controller 26. The controller 26 is provided with a liquid path 36 adapted to change flow path resistance by a piston 30 slidable in an oil chamber 34 and a solenoid 37. When the rotational frequency of the engine exceeds a certain value, a switch 29 is turned on to open the liquid path 36 so that the controller 26 has low damping characteristics not to transmit high frequency vibration to the car body. Thus, since the damping characteristics change corresponding to the rotational frequency of the engine, vibration-proof performance is improved and radiant noises can be reduced.

Title: Data processor
Inventor: NAOE TOSHIYUKI
IPC: G06F7/76
Filed: 1993-04-23
Abstract: PURPOSE:To efficiently perform data processing by changing a machine cycle required for the arithmetic operation of a multiplier corresponding to effective data word length. CONSTITUTION:A control signal EN is set at '1' when the effective data word length shows 32 bits. While, the control signal EN is set at '0' when the effective data word length shows 16 bits, and '0' is inputted to the latch control terminal L of a latch 3, and the latch 3 outputs an input signal as passing it through as it is. Also, an AND circuit 4c is turned off, which disables input to the carry input Cin of an adder 4b with CLA on a low-order side. Also, all the bits of the output of the adder 4b with CLA on the low-order side are changed to '0's compulsorily since no control signal EN is inputted to another input of an AND circuit 4d, and it is outputted to a latch 5. Thereby, it is possible to shorten the propagation delay time of a carry signal propagated between the 32 bits on the low-order side of an adder with CLA at the final stage, and the multiplication of one machine cycle can be executed.

IPC: B21K1/12
Filed: 1987-05-20
Abstract: PURPOSE:To prevent the deformation of a hole by arranging the elastic means having the projection fitting with the center hole of a shaft member and exerting a reverse force to the rear part of a center shaft inside a forming hole and the ejector extruding the center shaft at the outlet side of the forming hole of a forming die. CONSTITUTION:A shaft member W is pushed into a forming hole by a rolling reduction ram 6 and the groove in the axial line direction is formed on its axial end zone. On the end of face forming the center hole W1 of the shaft member W, the reverse force to the rolling reduction ram 6 is exerted by a coil spring 9 via a filler 8 and the groove in the axial line direction is formed in the state of the deformation of the end zone being avoided. The member W forming the groove pushes up a center shaft 7 in the direction of the rolling reduction ram 6 via a knockout pin 10 and filler 8 by an ejector 11 after ascending the ram 6. The deformation of the center hole can thus be prevented without any flaw and crack.

Title: Supoerconducting magnet device
Inventor: YAMAZAKI AKINORI
IPC: H01F6/00
Filed: 1994-06-02
Abstract: PURPOSE:To reduce the length of a superconducting magnet device by setting to a negative value at least one coefficient of the even order terms of the Taylor series expansion of a magnetic field distribution on a coil axis in an axial coorinate system and generating a magnetic field having a term whose coefficient is positive and has the same value as that of the even order term. CONSTITUTION:This superconducting magnet device has cylindrical superconducting coils 11a-11c. The shape, layout and ampare-turn of the coils are so adjusted that when the generated even order terms except the 0th order term are superposed, at least one of the coefficient of the 2nd, 4th, 6th, 8th and 10th order terms has a negative value. This allows the coil length/coil diameter to be reduced to about 1.0. A magnetic field generating means 12 is disposed on a magnetic body shin 8 to generate a magnetic field having the same value as the coefficients which are given negative values and positive values. Thus, on the whole, the even order terms can be made nearly equal to 0, except for the 0th one, and the device length can be reduced.

Title: Door frame for partition
Inventor: KIMURA TETSUYA
IPC: E04B2/82
Filed: 1991-05-27
Abstract: PURPOSE:To facilitate determining of a cutting position and to eliminate defective construction caused by an error in setting the cutting position. CONSTITUTION:In a door frame 1 for partition consisting of a lengthy vertical frame 2 and constituted by mounting a door to the vertical frame 2, at a position where a height allowance of a certain dimension is added to a height A of a required plinth 3 from the lower end of the vertical frame 2, a marker fitting 4 as a base for determining a cutting position 5 of the vertical frame 2 according to the height A of the plinth 3 is mounted. The cutting position 5 is determined at a position lowered by a height C of the plinth from the position of the marker fitting 4. Thus, only by actually measuring the height C of the plinth 3 adjacent to the position where the door frame 1 for partition is to be mounted and by lowering it by the actually measured value C from the marker fitting 4, the lowered position becomes the appropriate cutting position 5, the cutting position 5 can be easily determined without necessity of calculation and defective construction caused by an error in setting the cutting position 5 is eliminated.

Title: Method for purifying hydrogen gas
Inventor: NAKADA YASUSHI
IPC: C01B3/56
Filed: 1984-06-12
Abstract: PURPOSE:To purify H2 gas, by putting crude H2 gas into a vessel containing a metal hydride for occluding the H2, occluding the H2 in the metal hydride, decompressing the interior of the vessel, expelling the residual impurities, and repeating the above-mentioned operation plural times to recover H2 gas of high purity from the metal hydride. CONSTITUTION:H2 gas containing impurity gases, e.g. He, Ar, O2, H2O, N2, CO or CO2, is filled in a vessel containing a metal hydride, e.g. LaNi4.85Al0.15, under pressure, and occluded in the metal hydride. The interior of the vessel is then decompressed to a hydrogen occlusion pressure of the metal hydride to exple the above-mentioned impurity gases remaining in the vessel. The above-mentioned operation is repeated plural times. In at least the final operation, the H2 gas occluded in the metal hydride is partially released together with the impurity gases to expel completely the inpurity gases from the vessel. The occluded H2 gas of high purity is released from the metal hydride. Thus, the crude H2 gas is purified into the H2 gas of high purity for a long period without deteriorating the hydrogen occlusion ability of the metal hydride by the impurity gases.
