Title: Manufacture of oxide superconducting wire stock
Inventor: MAEDA HIROSHI
IPC: B21C1/00
Filed: 1988-06-28
Abstract: PURPOSE:To facilitate manufacture of oxide superconducting wire stocks by filling oxide superconducting powders into a silver sheath, cold drawing the sheath, and performing intermediate annealing at a temp. in a prescribed temp. range at each time when a fractional reduction in area indicates a specific value. CONSTITUTION:In the time of cold drawing work of a silver sheath containing oxide superconducting powders, at each halfway time when a fractional reduction in area reaches 2-50, intermediate annealing at a temp. in the temp. range of 100-300 deg.C. is performed. The silver sheath should have a proper hardness, that is, a hardness of Vickers 80-100 is required. A hardness of the sheath recovers a suitable value for cold drawing by performing the above annealing, so that generation of breakdown or cracks on the sheath is prevented. Hence, manufacture of oxide superconducting wire stocks is facilitated.

IPC: G05B19/02
Filed: 1978-12-18
Abstract: PURPOSE:To make it possible to detect previously a forecasted sequence delay by monitoring whether a stop circuit is normal or not and whether a start circuit is normal or not in the operation time and the stop time respectively at a fixed period. CONSTITUTION:Assuming that an output command is given to a sequence controller, for example, in a water-wheel generator, an entrance valve start command is issued under interlock conditions A-D satisfied. Next, when feedback condition G indicating that the entrance valve opens fully is returned, a start command is issued under this condition G and interlock conditions E and F satisfied. Assuming that the generator stops, interlock conditions of a start circuit are checked for normalcy at every fixed period by a program, and a condition indicator lamp and an operation state indicator lamp are lit on a display equipment to issue alarm if conditions are not satisfied. Interlock conditions of a stop circuit are checked at every fixed period in the operation time of the generator also. As a result, preventive maintenance for sequence delay can be performed.

Title: Nonaqueous solvent battery
Inventor: OISHI HIROMI
IPC: H01M2/08
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To enhance mechanical strength of a glass seal against an impact in a sealed nonsaqueous solvent battery in which positive and negative electrodes are insulated by sealing with the glass seal. SOLUTION: In a nonaqueous solvent battery of a sealed type using a glass material 10 as an insulator between a positive and a negative electrode, a metallic flange 12 is fixed to a positive electrode terminal 11. The glass material 10 is filled in a space surrounded by the positive electrode terminal 11, the metallic flange 12 and a metallic cover 9.

Title: Fuel feeding device for internal combustion engine
Inventor: ISHIDA KAZUMI
IPC: F02M69/00
Filed: 1987-06-25
Abstract: PURPOSE:To improve the drivability at the time of deceleration of a vehicle by partitioning the intake air passage of an internal combustion engine into a small diameter passage and a large diameter passage, providing a throttle valve in each of both passages and interlocking these throttle valves, and providing a fuel injection valve on the upper course side of the throttle valve in the small diameter passage. CONSTITUTION:At the time of stepping an accelerator, both throttle valves 2, 3 are interlockedly opened in accordance with it. The air quantity in an intake air passage 1 is determined by the openings of the throttle valves 2, 3 and a fuel corresponding to an intake air quantity is injected from a fuel injection valve 4. The injected fuel arrives at the throttle valve 2 and a part of the fuel is deposited on it whereas the remaining greater part collides against the valve face of the throttle valve 2 and, then, fed into an internal combustion engine in a favorably atomized condition from the gap between the peripheral edge of the valve 2 and the inner wall of a small diameter passage 11. In this case, the deposited quantity of fuel to the throttle valve 2 can be small because of a small valve diameter. Thereby, when air quantity is reduced, the quantity of fuel is rapidly reduced accordingly, restraining the degree of air-fuel ratio from becoming rich while eliminating the occurrence of the misfire of an engine.

Title: Light supplying device for culturing plant
Inventor: SETO ATSUSHI
IPC: F21V8/00
Filed: 1988-06-27
Abstract: PURPOSE:To efficiently and uniformly supply light to plant by providing means for taking the light from natural light sources or artificial light sources and means of projecting the taken light toward the plant. CONSTITUTION:Optical fibers 7, 8 are made by using a polymethyl methacrylate (PMMA) material as a core. Since this PMMA material has an effect of absorbing the IR component of the light, only the IC component is attenuated from the natural light and is sent to a lighting chamber 1. The quantity of the natural light is detected by an optical sensor. The sodium lamps of lighting devices 6 are hardly lighted when the natural light is relatively strong. The sodium lamps are properly lighted when the natural light is weakened by a bad weather or the like. The light is supplied always adequately into the culture chamber 1 in such a manner. Since the light supplied at this time hardly contains the IR rays, the heating up in the culture chamber is obviated.

Filed: 1980-11-11
Abstract: PURPOSE:To simplify the constitution of a demodulating circuit of a transmission system in the same direction that transmits the data and the clock in the same direction, by using a digital PLL at the clock extracting part. CONSTITUTION:A clock extracting part 20 consists of a digital PLL21 and an oscillator 22 of 8MHz. Thus the part 20 is formed with a digital circuit as a whole and easily formed into an IC. Then the 3rd unipolar code row (U1+U2) is decoded with use of generated clocks CK1 and CK2, and accordingly the output (a) of a decoder 14 has the same information as the original data of 64kHz. At the same time, a violation detecting part 15 using the above-mentioned clocks easily detects a violation by making use of the 2-bit continuous unipolarity of the code row (U1+U2). As a result, a demodulating circuit of the same direction transmission system is formed with a simple constitution and also is easily formed into an IC.

Abstract: PURPOSE:To obtain the etching method with which no characteristic deterioration is generated after etching by a method wherein an etching is performed using a cylinder-shaped device at first, and then the second etcing is performed in vertical direction with end face matched to the mask face using a flat plate type device. CONSTITUTION:An etching is performed on an amorphous silicon diode thin film 3 using a cylinder-shaped device. At this point of time, no overetching is existed and as the etching is performed at a high speed of 60-100A/sec in a short time using several Torr of CF4, the rise in temperature is small and no diode characteristics are deteriorated. Then, the manufacture of the diode is completed by performing a reactive ion-etching using a flat plate type device. Said etching is to be performed at the speed of 10A/sec or thereabouts using CF4 of 0.1-1 Torr. At this point, as the amorphous silicon diode thin film 3 to be etched is very small in area and very ting in thickness, the etching can be finished in a short time and no temperature rise is generated.
