Title: Column structure for machine tool
Inventor: TAKADA TORU
IPC: B23Q1/00
Filed: 1991-02-19
Abstract: PURPOSE:To prevent uneven thermal deformation of a column, and improve a work precision by a precise machine tool. CONSTITUTION:In addition to first linear guide mechanisms 18, 20 at a column 14 to guide a main shaft head 22, second linear guide mechanisms 60, 62 are provided in a back surface of the column 14 almost at symmetric positions to the first linear guide mechanisms 18, 20 to guide a balance weight 64. Heat generation at a guide part corresponding to elevation of a main shaft head 22 occurs not only at a front surface of the column 14 but it occurs at the back surface of the column 14 to make the heat distribution of the column 14 symmetric at the front and back. Inclination of the column 14 back by a temperature rise at a guide part 18 of the main shaft head 22 can thus be prevented, and the work precision can be improved.

Title: Method for recovering isotope of hydrogen
Inventor: MITSUISHI NOBUO
IPC: B01D59/26
Filed: 1986-03-05
Abstract: PURPOSE:To separate and to recover isotopes of hydrogen selectively with a simple procedure and at high recovering efficiency by allowing a gaseous mixture consisting of at least one kind of hydrogen isotope and inert gas to contact with a packed bed of Y particles at a specified temp. to absorb the hydrogen isotope, then eliminating the hydrogen isotope by heating. CONSTITUTION:A gaseous mixture consisting of at least one kind of hydrogen isotope among H, deutrium, and tritium, and inert gas (e.g. Ar) is passed through a packed bed packed with Y particles in, for example, quartz tube, etc., for <=1-2sec contact time at 100-200 deg.C to contact with the Y particles and to absorb the hydrogen isotope selectively. Then, the packed bed is heated at 800-1,000 deg.C, and sucked simultaneously with a vacuum pump to eliminate the hydrogen isotope. Thus, hydrogen isotope is recovered.

Title: Negative pressure responsive valve
Inventor: KITAMURA KAZUHIKO
IPC: F16K17/22
Filed: 1980-04-10
Abstract: PURPOSE: To provide a small-sized negative pressure responsive valve which may be stored in a small space by a method wherein a fluid flow passage is made to be opened when a pressure is found in the valve higher than a specified negative pressure and also higher than a specified rate of variation of the negative pressure.  
     CONSTITUTION: When a negative pressure higher than a first predetermined value is fed from a signal port 29 to the chambers 24, 27, the first pressure plate 14 is displaced in a leftward direction while the negative pressure is applied to the chamber 24, the shoulder part of the annular plate 15 is abutted against the valve 34, the valve 34 is opened to communicate with the surrounding air passage and the the passage is communicated with the output port 36. In the same manner, the valve 34 is opened due to a negative pressure in the chamber 27 and delayed due to an orifice 40, thereby a negative pressure in the chamber 27 and delayed due to  an orifice 40, thereby a negative pressure in the chamber 26 is increased and finally  returned back to the original position. When a rate of variation of the negative pressure in the chamber 27 is exceeded over a predetermined value, the valve 34 is  released to open through a leftward displacement of the second pressure plate 17.  In this way, it is possible small-sized negative pressure responsive valve which may  be installed in a narrow space.

Title: Boosting oscillating circuit
Inventor: KANEDA ISAO
IPC: H03K3/57
Filed: 1980-04-10
Abstract: PURPOSE:To raise an oscillation output voltage by using a nonlinear capacitor for a boosting oscillating circuit. CONSTITUTION:As power source 1 is put to work, nonlinear capacitor 6 is charged via inductor 2. Once the voltage across capacitor 6 exceeds a prescribed value, thyristor 5 conducts. As discharge current i2 decreases below a holding current, thyristor 5 turns off. Then, the charge of capacitor 6 restarts. As a result, electromagnetic energy accumulated in inductor 2 increases the rising speed of the charged voltage across capacitor 6. When an oscillation voltage enters the nonlinear range of capacitor 6, the oscillation output voltage rises rapidly and an oscillation frequency also increases. Then, even if a voltage applied later rises, the charged voltage across capacitor 6 is nearly constant.

Filed: 1982-03-23
Abstract: PURPOSE:To obtain a layer-built fuel cell having simplified structure, by varying the shape of flow path for fuel and oxidizing agent and mounting manifolds only on two side faces of the lamination. CONSTITUTION:In a fuel flow path 6a, fuel will enter through a plurality of flow-in ports arranged in the central portion then advance straight and turn to the left or right near the opposite end face to advance in the direction opposite from the advancing direction then discharge through a flow-out port. Said flow path has approximately rectangular cross-section of such dimension that the pressure loss in the entire length of each flow path will be same. The oxidizing agent flow path 6b is provided with flow-in and flow-out ports on one face provided with the fuel flow path 6a of the gas separating board 6 and the other face at the rear side symmetrically with the fuel flow path 6a against the center line.

IPC: H01B13/00
Filed: 1994-02-23
Abstract: PURPOSE:To affix a tape member which consists of an aerotropic conductive sheet and a paper base onto a transparent base plate smoothly by maintaining it in a properly tensed condition. CONSTITUTION:A tape member 5 is given a prescribed tension by delivering the tape member 5 from a feeding reel 10, drawing it with a delivery roller 12, making a prescribed length of the tape member 5 stocked in a stocking part 14, and generating an attracting force in the stocking part 14 by applying negative voltage through an attracting passage.

As a result, the tape member 5 is affixed onto the transparent base plate 1, completely eliminating the risks that excessive tension may be applied along the entire running route of the tape member 5 or a crease may be generated. It is thus possible to affix the tape member 5 smoothly and accurately.

Title: Frequency adjustment method in lc composite component
Inventor: OKAMURA NAOTAKE
IPC: H01F27/00
Filed: 1989-02-27
Abstract: PURPOSE:To adjust the frequency characteristic without changing a composite component and to reduce the cost by varying the thickness of a sheet layer interposed between an LC component main body and a shield electrode film so as to change the frequency of the composite component. CONSTITUTION:Pattern electrodes 3, 4 are provided to both faces of a dielectric layer 2 to form an LC composite component main body 1. Then a pattern is formed to shield electrode films 7, 8 via sheet layers 5, 6 with lots of sheet films 5a, 6a laminated to both sides of the main body 1. The thickness of the layers 5, 6 is adjusted by coating the films 5a, 6a with a prescribed thickness to the layers 5, 6 as a multilayer. When a gold layer with a high conductivity rate is formed in existence near an electronic component, the frequency of the electronic component is varied depending on the distance. Thus, number of times of coating of the layers 5, 6 is adjusted to vary the thickness thereby setting the frequency to a desired value. Thus, the frequency of the composite component is easily adjusted and the cost is reduced.
