Title: Hydrogen adsorbing membrane
Inventor: NARITA KAZUNARI
IPC: B01D53/22
Filed: 1986-02-27
Abstract: PURPOSE:A hydrogen adsorbing membrane having improved action on selective adsorption of hydrogen contained in a diffusing gas, obtained by dispersing metallic powder having hydrogen adsorbing ability into a plastic having gas permeability. CONSTITUTION:Metallic powder 12 having hydrogen adsorbing ability is dispersed into a plastic 11 (e.g. polyethylene) having gas permeability to constitute an aimed hydrogen adsorbing membrane 13. Powder such as Pd, Pt, Ni, Ti, Fe, etc., having <=about 1,000Angstrom particle diameter is preferable as the metallic powder 12. When a hydrogen-containing gas is brought into contact with one side of the prepared hydrogen adsorbing membrane 13 under pressure, the gas diffuses through the hydrogen adsorbing membrane 13 and hydrogen is adsorbed on the metallic powder 12 during the diffusion. In the operation, since the product l1Xl2Xl3 of longitudinal dimension l1, lateral l2 dimension and thickness l3 as a factor acts on the hydrogen adsorbing ability of the hydrogen adsorbing membrane 13, hydrogen adsorbing effects are extremely improved.

Title: Conversion transformer
Inventor: MIYAZAKI HIROSHI
IPC: H01F27/24
Filed: 1991-03-08
Abstract: PURPOSE:To change inductance in accordance with temperature variation by changing the gap condition between cores by changing temperature using a gap changing means inserted between a plurality of cores. CONSTITUTION:When temperature goes down from the normal temperature to a low temperature, for examle, when it drops to a temperature in the neighborheood of 0 deg.C, the shape of the spacer 5 inserted between cores 3a and 3b is deformed to a corrugated form from a tabular form. As a result, the gap between the cores 3a and 3b is made wider two to three times of the gap in the normal temperature. When the gap is made wider as above-mentioned, the inductance of a conversion transformer 1 decreaseds by 1/2 to 1/3 or thereabout wen compared with that in the normal temperature. Accordingly, the inductance of the conversion transfomer 1 at low temperature can be changed. To be more precise, inductance can be changed in accordance with the variation of temperature.

Title: Liquid crystal display device
Inventor: HIROSHIMA MINORU
IPC: G02F1/1343
Filed: 1993-03-05
Abstract: PURPOSE:To prevent the generation of short circuiting between the electrodes of thin-film transistors(TFTs) by setting the pattern angle of the patterns of these TFTs at a specific value or below. CONSTITUTION:The two TFT1, TFT2 provided at respective pixels are respectively formed with the same size and have a gate electrode GT, a gate insulating film, an i type semiconductor, a pair of source electrode SD1 and drain electrode SD2. The angle theta of the patterns of the TFT1 and TFT2, i.e. the gate electrode GT, the source electrode SD1 and the drain electrode SD2 is so set as to be <=240 deg.. By this constitution, photoresist does not remain in the angle parts of the patterns of the TFT1 and TFT2 and, therefore, the sure formation of the films to be formed next in the angle parts is possible. Consequently, the short circuit between the gate electrode GT, the source electrode SD1 and the drain electrode SD2 does not arise any more.

IPC: B60L50/16
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of take-off assist by providing controlling means for controlling to increase/decrease input torque of an electric motor. SOLUTION: For take-off assist, output torque of electric motors 7L, 7R are controlled in order to prevent a rear wheel from slipping. Acceleration of each left and right wheel is calculated based on the signal variation of a rear wheel speed sensor, then it is judged whether or not each acceleration is above the first set value, a criterion for slip. If the acceleration is above a first set value, it is judged whether or not the acceleration is below a second set value criterion for grip recovery. If the acceleration is below the second set value, a target value of output torque of the respective electric motors 7L, 7R is set higher. If the acceleration is above the first set value, a target value of output torque of the electric motors 7L, 7R is set lower. Each of the electric motors 7L, 7R is thereby driven controlled so that its output torque becomes the target value.

IPC: B23K10/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce cutting time in cutting plural members from one sheet of material to be cut. SOLUTION: A route for a cutting torch A is set by arranging plural members on a material B to be cut. In a route from one member to the next, the supply of plasma gas to the cutting torch A is maintained, with energization stopped between the electrode of the cutting torch A and the material B, and with the supply of shielding gases also stopped. With the cutting torch A reaching a start position for cutting a new member, power is supplied between the electrode and the nozzle to form a pilot arc; after a prescribed time, it shifts into the main arc, carrying out the cutting of the member. Since the supply of plasma gas is continued for the cutting torch A, no time is required for the pre-flow in forming a pilot arc, thereby enabling cutting time to be reduced.

Abstract: PURPOSE:To prevent an output voltage from varying by providing a capacitor and a charging/discharging circuit of the capacitor in the tertiary winding of a transformer for driving a switching element. CONSTITUTION:A switching regulator outputs a constant voltage by connecting a DC power source 1 with a series circuit of the primary winding 3 of a transformer 2 and a switching transistor (Tr) 4, driving the base of the Tr 4 through a voltage controller 11 from the tertiary winding 9 and rectifying and smoothing the voltage induced in the secondary winding 5 by rectifying and smoothing circuits 5, 6.

Filed: 1978-04-19
Abstract: PURPOSE: To detect the extinction of a light source with wide operation tolerance by a simple constitution, by detecting that at least one of transistors goes off judging from the variation in the photo current of the series circuit of transistors.
