Title: Method and apparatus for detecting liquid
Inventor: MORIMOTO KAZUO
IPC: G01F23/28
Filed: 1982-07-05
Abstract: PURPOSE:To decrease the misjudgement, by generating ultrasonic waves from an inner pipe toward the outside and propagating at a position of a double cylinder leaving a prescribed distance and then, detecting the presence or absence of a liquid in a gap of the double cylinder by the intensity of the received ultrasonic waves. CONSTITUTION:The apparatus is inserted into an inner pipe 1 of a double cylinder constituted by the inner pipe 1 and an outer pipe 2. A main body 3 and a casing 5, are tuned with an axis core of the pipe 1 by stabilizers 4 and 13. The body 3 is rotated around the axis core by driving a motor 6 fixed to the casing 5 and ultrasonic waves are oscillated so as to form the conical surface. Propagating waves from all directions are measured because an ultrasonic receiver is rotated with an oscillator 5. The mean value or the lowest level of the received ultrasonic waves is detected in an operation processing circuit. When a liquid exists in a gap between the pipe 1 and 2, the ultrasonic waves are damped, but is amplified by a reflected wave when the pipe 2 is placed closely near the pipe 1.

Title: Operation of fuel-cell generating system
Inventor: JINBO TAKASHI
IPC: H01M8/06
Filed: 1981-07-27
Abstract: PURPOSE:To enable reforming reaction to be performed, while maintaining CO concentration of a fuel gas below the tolerance limit above which an electrode is deteriorated, by dare restricting the invert ratio of methanol to below 95% by appropriately selecting LHSV or the like during the steam reforming of methanol. CONSTITUTION:The reaction temperature and the molar H2O/methanol ratio of the steam reforming are made the same as those of the conventionally used condition. Although CO concentration decreases as the molar H<2>O/methanol ratio increases, the suppression of CO concentration becomes little recognized when the molar H2O/methanol ratio exceeds 3.0. The reaction pressure of the steam reforming is around 1-10 atmospheric pressures, and is desired to be higher than the pressure of a fuel-cell body. Since the invert ratio of methanol is restricted to a low value, designing of a reformer becomes easy, the reformer can be driven at lower temperature, and the reformer itself can be made small. In addition, since produced surplus steam can be utilized for methanol recovery, there is almost no reduction of the generation efficiency of the fuel cell.

The entry surface 2a on the white board 2 is transparent, so even when the information drawn on the entry plane 2a once is erased, the data can be reproduced and displayed. Consequently, the information need not be written again on the blackboard manually and the trouble is eliminated.

Title: Semiconductor device
Inventor: YUZURIHA KOJIRO
IPC: H01L29/78
Filed: 1989-05-09
Abstract: PURPOSE:To alleviate a stress generated at the time of heat treatment and to prevent a crystal defect from generating by forming a thermal stress alleviating film between a semiconductor substrate and an isolating insulating film. CONSTITUTION:A groove 2 having a desired depth is formed on a region to be isolated of a p-type silicon substrate 1 by photolithography and anisotropic etching. Then, a polycrystalline silicon film 6 is formed as a film for alleviating a thermal stress between the substrate 1 and a silicon oxide film 4 to be buried therefrom by a chemical vapor growing method. After the thin polycrystalline silicon film except those formed at the bottom and sidewall of the groove 2 of the silicon 6 is removed, the film 4 is thickly deposited, and etched back to complete a groove buried isolation. This film 6 alleviates a stress generated due to the difference of thermal expansion coefficients of the substrate 1 and the film 4 in a later heat treating step thereby to prevent the crystal defect of the substrate.

Filed: 1984-06-08
Abstract: PURPOSE:To prevent the generation of strain by forming a flow-introducing plate shaping a flow introduction through press working in a lead-out section for a foil-wound transformer. CONSTITUTION:An insulating medium is encapsulated into a tank 1, and a core 2 is mounted to the inside of the tank. A low-tension winding 4 is wound on the outside of a main leg 2a for the core 2 through an insulating cylinder 3, and a high-tension winding 5 is wound on the outside of the low-tension winding 4 through an insulating barrier 6. A cooling duct 9 extending in the axial direction of the windings 4, 5 is rolled into and incorporated into the windings 4, 5. A refrigerant for the cooling duct 9 is liquefied by a condenser 10 mounted outside the tank 1 and stored in a refrigerant tank 11, and forwarded into the cooling duct 9 by a pump 12. A flow introducing plate having high stiffness is formed through press working in place of conventional welding constitution as a flow introducing plate 26. According to the method, heat is not applied to the flow introducing plate 26, thus generating no strain, then resulting in precise machining.

Title: Swing pump
Inventor: ITOU KAZUICHI
IPC: F04C9/00
Filed: 1981-07-25
Abstract: PURPOSE:To simplify sealing, by producing pump-action with only conical motion, without rotation of a swing plate installed as one body in a spherical body which is supported by a pump casing. CONSTITUTION:When a drive source 20 is driven, a conical ring 28 rotates around a drive shaft 22 and since this conical ring 28 is pressed to a drive disc 18, it moves along the circumference of the disc 18 while rotating itself according to this rotation. At this time, the disc 18 is no longer rotated because its integrated swing plate 9 is prevented from rotation by means of a diaphragm body 12. Therefore, according to rotation around an axis of the shaft 22 of the conical ring 28, a swing plate 16 will carry out conical motion around a point O and thereby a contact part between surfaces 10 and 11 of the swing plate 9 and the side of a hollow chamber 3 moves in the circumferential direction; pump-action is thus achieved.

Abstract: PURPOSE:To simplify structure by arranging a spool type servo-mechanism into the thick body part of a housing into which a stub shaft and an operating shaft are inserted and arranged. CONSTITUTION:When a stub shaft 10 is turned by turn-operating a steering wheel, a torsion angle is generated on a torsion bar 11, and a relative turning displacement is generated between the stub shaft 10 and an operating shaft 12. Then, a relative turning displacement is generated also between the projection 29 formed onto the stub shaft 10 and the projection 31 formed onto the operating shaft 12, and the projection part 29 presses the inner surface of the spiral groove 28 formed onto a cylindrical member 27, and turns in the direction of the axis of the cylindrical member 28. Then, a pressing member 20 installed onto the cylindrical member 27 shifts in the axial direction, and a spool valve 14 is pressed by a valve operating arm 20a, and the steering hydraulic pressure can be controlled.

Title: Plasma display board and its manufacture

IPC: H01J11/38
Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To reduce the disposal quantity of lead glass becoming waste when ribs are formed by a sand blast method by forming a board, cross-sectionally post-like formed bodies of an inorganic oxide arranged on the board, and a thin film of lead glass on the surfaces of the formed bodies or the entire surface of the board arranged with the formed bodies. SOLUTION: Rib-shaped formed bodies 30 are formed on a board 10 by using inorganic oxide. In this case, an organic binder may be included so as to improve formability if it can be vanished by baking. Then, ribs 20 wherein the inorganic oxide is coated with lead glass 40 are formed by applying lead glass paste prepared by kneading the lead glass 40, an appropriate resin and solvent to the surfaces of the formed bodies 30 by a method such as screen printing or the like, and melting the lead glass 40 by baking it at a suitable temperature after drying it. As a result, what is formed into a rib-shaped form is only the inorganic oxide in the rib forming material even if the ribs 20 are formed by a sand blast method and hence, the lead glass 40 is not included as waste.
