Patent JP-S62104654-A (JP)
Title: Nozzle for continuous casting
Inventor: YAMADA KOICHI
IPC: B22D11/10
Filed: 1985-10-12
Abstract: PURPOSE:To prolong an exchanging term of a nozzle by constituting an inner surface of the nozzle to be brought into contact with molten steel with a sintered material contg. each specified mol% of zirconia and magnesia. CONSTITUTION:Nozzle body 1 is formed of refractory material having alumina- graphite quality. A formed material contg. zirconia and magnesia capable of fitting closely to the inner surface of the nozzle to be in contact with molten steel, is formed and coated on the inner surface of the nozzle as a sintered material. At this time, the sintered material layer 2 is sintered under composition of, by mol%, 85-97% zirconia and 3-15% magnesia, and coated through a binder or plasma thermal spray. As the zirconia sintered body to be an oxygen ion conductor carries oxygen in the molten steel therein electro-chemically, it prevents deposition of sticking materials such as alumina or silica, etc., on the inner surface of the nozzle. Thus, the exchanging period of the nozzle is extended.

Title: Variable displacement compressor
Inventor: KUROSAWA JUETSU
IPC: F04B49/00
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent an increase of noise and a decrease of performance by suppressing wearing between a guide groove and a cylindrical part of a rod, and impede rotation of a tilt rotary plate around a shaft orthogonal respectively to the center axis of a shaft and the tilt rotary plate by a simple hinge mechanism. SOLUTION: A hinge mechanism 41 is constituted by a linear guide groove 10f provided in a swash plate 10 and a rod 43 fixed to a thrust flange 40 to have a cylindrical part 43a slidably fitted to the guide groove 10f. A center axis of the cylindrical part 43a of the rod 43 is provided substantially at a right angle in a lengthwise direction of the guide groove 10f. In accordance with a change of pressure in a crank chamber 8, the cylindrical part 43a of the rod 43 is relatively slid in the guide groove 10f, a tilt angle of the swash plate 10 is changed, but here, by relatively moving the cylindrical part 43a of the rod 43 in a condition of line contact relating to an internal wall surface of the guide groove 10f, wearing is suppressed. Since a center axis of the cylindrical part 43a of the rod 43 is substantially at a right angle in a lengthwise direction of the guide groove 10f, and, by the single rod 43, rotation of the swash plate 10 around a shaft orthogonal to a center axis of the swash plate 10 is impeded.

IPC: H01L21/66
Filed: 1982-12-28
Abstract: PURPOSE:To test the polarity identification mark positively by a method wherein a control circuit, which determines the direction of the test current by a light signal of at least two sensors which detect the polarity identification mark, and a signal circuit, which produces a discrimination signal between an article of good quality and an article of poor quality according to the direction of the test current and the polarity identification mark, are provided. CONSTITUTION:A polarity identification mark 3 is applied to a cathode side of a resin molded part 2 of a semiconductor element 1. So the light input of the reflected light to an optical sensor 41 is different from that to an optical sensor 42 and the side to which the polarity identification mark is applied is electrically identified by a light signal identifying circuit 5. Then, current i is applied to an anode side (a) by a current application control circuit 6 and as the polarity agrees with the identification mark 3 the specified current flows and the article is judged to be of good quality. On the other hand, when the polarity identification mark 3 is to the side of the optical sensor 41, the current is applied from the cathode side (b) to the anode side (a) by the control circuit 6. While, the direction of the current is reverse to the direction of the rectification of the semiconductor element 1, the current does not flow and the article is judged to be of inferior quality.

Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp lighting device which has good efficiency of the lamp load even when the lamp is on in the low light flux dimmer condition and can preclude darkening of the end of the lamp or its being put off in the dimmer condition. SOLUTION: Piezo transformers A and B having different resonance frequency are connected parallel, and a high frequency power supply 1 for driving the transformers A and B is connected with their primary side terminals, while one end of a discharge lamp load 2 is connected with their secondary side terminals. When the lamp load 2 is full lighted, the drive frequency of the power supply 1 is controlled so that the transformers A and B are driven near the resonance frequency f1 of the transformer A, and when lighted in dimmer condition, the two transformers A and B are driven upon lowering the drive frequency by a dimmer control circuit 5 down to near the resonance frequency f2 of the transformer B. Even when the lamp load 2 is lighted in dimmer condition, a high efficiency at the same level as fully lighted can thereby be maintained.

Abstract: PURPOSE:To automatically keep car height at a set level by providing a leveling valve for cargo handling, a manually operated lever, a valve bar and a control arm projectedly provided through a clutch and of which end is rotatably secured to an axle through a link mechanism. CONSTITUTION:When 'cargo handling' of a cargo handling/running change-over switch 017 is selected in cargo handling, the air flow to a leveling valve 1 for running is cut-off, and car height is adjusted by operating the leveling valve 1 for cargo handling directly by means of a manually operated lever 5-3 instead of the UP/DWN operation of an elevator switch. After adjusting car height, since when a car height switch is turned on to select 'fitting' of a clutch 10, an arm 12 is fixed to the spool shaft 5 of the leveling valve 1 for cargo handling, car height is automatically kept at a set level regardless of the increase or decrease of loading weight by changing-over the leveling valve for cargo handling taking the fixing position of the arm 12 as a new neutral position.

Title: Production of lightweight inorganic plate
Inventor: NISHIZAWA KAZUHIDE
IPC: C04B22/06
Filed: 1991-08-12
Abstract: PURPOSE:To obtain a lightweight inorganic plate excellent in dimensional stabil ity by blending the specified amount of magnesium oxide and/or magnesium hydroxide with a raw material for producing the lightweight inorganic plate and molding the mixture into a plate and thereafter performing steam-curing therefor. CONSTITUTION:(A) 20-85wt.% cement (e.g. porthand cement), (B) 5-10wt.% organic fiber (e.g. ligneous pulp), (C) 5-15wt.% lightweight aggregate (e.g. 'SHIRASU' balloon) and (D) 2-20wt.% magnesium oxide and/or magnesium hydroxide are mixed. Then a lightweight inorganic plate is obtained by forming the mixture into a plate and thereafter performing steam-curing. Thereby when gaseous carbon dioxide in the air infiltrates into the structure of the lightweight inorganic plate after production thereof, this gaseous carbon dioxide preferentially reacts magnesium hydroxide in the structure and acicular crystal of neutral magnesium carbonate is produced. Therefore reaction of both gaseous carbon dioxide and cement hydrate expanded in the structure is inhibited. As a result, shrinkage of the structure is inhibited.
