Title: Detection of hydrogen corrosion of equipment material
Inventor: SHIMOMURA JUNICHI
IPC: G01N17/00
Filed: 1988-07-28
Abstract: PURPOSE:To detect possible generation of a hydrogen corrosion caused in a pressure container and a piping by performing a forcible occlusion of hydrogen from the surface of an equipment material at an electrolytic current density/ electrolyzing time according to a specified electrolyte and the type of steel. CONSTITUTION:A forcible occlusion of hydrogen is performed from the surface of an equipment material by a electrolyte hydrogen charging method. In this case, the density of an electrolytic current varies with the combination of an electrolyte and the type of steel and an electrolyzing time of an electrolyte below 60 deg.C is set at one hour. This allows non-destructive detection of the generation of a hydrogen corrosion in the equipment material of a pressure container, piping and the like applied in a high temperature and high pressure hydrogen environment, thereby preventing an accident caused by degrading in quality.

Title: Production of optic information recording material
Inventor: UMEHARA MASAAKI
IPC: G11B7/24
Filed: 1981-11-27
Abstract: PURPOSE:To obtain the titled recording material excellent in sensitivity, stability and preservability, by a method wherein a translucent thin metallic layer is produced on a substrate by electroless plating, and a solution containing a coloring matter and a binder is coated on the metallic layer to produce a heat- deformable light-absorbing layer. CONSTITUTION:A plating bath containing a metallic salt (e.g., silver nitrate) and a reducing agent (e.g., formaldehyde) as primary constituents is prepared, and electroless plating is conducted by immersing the substrate (e.g., an acrylic resin plate) into the bath to produce the translucent thin metallic layer on the substrate. The thickness of the metallic layer is so adjusted as to attain a reflectivity of 15-75%. Then, a soltuion prepared by dissolving a binder (e.g., polyvinyl alcohol) and a coloring matter (e.g., water blue) into a solvent (e.g., water) is coated on the metallic layer to produce the light-absorbing layer. The thickness of the light-absorbing layer is adjusted to within the range of  0.1- 10mum. The optic recording material thus obtained is excellent in mass- producibility and enables sensitivity wavelength region to be freely selected.

Title: Motor control circuit for blower of air conditioner
Inventor: KIYABU KAZUHIKO
IPC: H02P1/16
Filed: 1984-09-10
Abstract: PURPOSE:To eliminate an excessively large rush current to a semiconductor power control element by connecting a negative temperature coefficient resistance element in series with the control element inserted in series with a blower motor. CONSTITUTION:A blower motor 3 is connected through a negative temperature coefficient element 11 and a semiconductor power control element 2 with an AC power source 1. The element 11 is mounted in a case 12 of the motor 3. When a trigger signal is applied to the gate of the element 2, the resistance value of the element 11 is large. Accordingly, an excess rush current does not flow into the element 2. When the element 2 rises at its temperature so that the plate 12 becomes high at its temperature, the element 11 rises at its temperature, and its resistance value decreases. Thus, the element 11 does not disturb the power supply to the motor 3 from the power source 1 in the normal state.

Title: Position deviation correcting system
Inventor: MIYAMOTO HIDETAKA
IPC: G11B15/68
Filed: 1990-07-18
Abstract: PURPOSE:To exactly grasp a position deviating amount and to accurately correct it by controlling the drive of a motor so that the position deviation amount can be within a prescribed stop position range amount. CONSTITUTION:When a medium conveying mechanism part 11 deviates the position from a stop position by disturbance such as earthquakes, etc., an MPU 16 reads a position data Xn from a counter in a fixed cycle and calculates difference from a stop position data Xm stored in advance so as to calculate a position deviating amount Xl. Next, the position deviating amount Xl is compared with a prescribed position deviation detecting amount and in the case of Xl>=l, a position deviation correcting current imax is set. Then, the position deviating amount Xl is calculated again and it is discriminated whether the position deviating amount Xl is within a stop position range amount L or not. In the case of X<L, a holding current imax is set. Thus, since the position deviation of the medium conveying mechanism part 11 is detected by an encoder 13 fitted to a DC motor 12 and the drive of the DC motor 12 is controlled, the position deviating amount can be exactly grasped and accurately corrected without limiting the sensitivity or position of a sensor as conventional.

Title: Casting method and casting apparatus
Inventor: WRIGHT LESLIE CHARLES
IPC: B22D11/119
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To make a casting system higher in flexibility and controllability by supplying molten material to a casting position from a vessel so as to substantially continue during casting and further, supplying the molten material into the vessel from a molten metal source at a specific time. SOLUTION: The molten metal is discharged into a heated tundish 22 from a ladle 20 and flowed into a head box 24 from the tundish 22 and thereafter, supplied into a casting nozzle 26. The supplying ratio from the ladle 20 to the tundish 22 is less than 50% of the casting time and much larger than the discharging quantity. Therefore, the supply of the molten metal into the tundish 22 is not at all necessary in a large part of the casting time. At the time of using the molten metal supplying system at this time, the molten metal in the ladle 20 is emptied at far before completing the casting from the tundish 22. In such a way, the other ladle 20 can be prepared by this system.
