Title: Aluminum based bearing alloy
Inventor: KAGOHARA YUKIHIKO
IPC: C22C21/00
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To provide an aluminum based bearing alloy with excellent fatigue resistance, non-seizuring property and wear resistance and enhance its rollability by preventing an intermetallic compound produced by added elements from becoming acicular. SOLUTION: The aluminum based bearing alloy comprises Sn of 3.5 to 20 wt.%, Si of 0.5 to 4.5 wt.%, Mn of 0.01 to 2 wt.%, and V and/or Mo of 0.01 to 2 wt.%, with the rest being substantially Al. Sn, Si, Mn and the like are added to Al to enhance the fatigue resistance, non-seizuring property and wear resistance of the bearing alloy. The addition of various elements to Al results in a higher probability of a brittle acicular intermetallic compound forming within a matrix, while the addition of V and/or Mo prevents the intermetallic compound from becoming acicular but instead forms it into solid. The intermetallic compound is solidified to maintain the toughness of the bearing alloy and achieve high strength.

Title: Operating method for steam-gas complex cycle power generating plant and power generating plant thereof
Inventor: HATANO ETSUICHI
IPC: F01K23/10
Filed: 1988-12-19
Abstract: PURPOSE:To prevent a low pressure turbine and a reheater from being overheated by starting a plant with a steam turbine which is driven by starting steam fed from a steam feed device for starting. CONSTITUTION:In a plant starting process, steam is introduced from a steam feed device 44 for starting to a low temperature reheat pipe 19, and a low pressure turbine 24 is driven by the steam so as to start a gas turbine 4 thereby. Therefore, when a power train system is in rotation, steam flows always to a reheater 7 and the low pressure turbine 24 passing through the low temperature reheater pipe 19, and the heating pipe of the reheater 7 is not heated to be damaged by exhaust gas of the gas turbine 4, and the low pressure turbine 24 is not set to a high temperature by a windage loss. On the other hand, in the case that the reheater 7 is not well heated, the low pressure turbine 24 is not driven by low temperature steam since the steam is fed switchingly to the low pressure turbine 24 after being passed through a high temperature reheat pipe 20.

Inventor: HONCHI YASUKO
IPC: B29C48/305
Filed: 1991-12-04
Abstract: PURPOSE:To prevent a decrease in illuminance of an inner illumination by employing a film made of thermoplastic polyimide as a protective transparent member of the illumination. CONSTITUTION:A protective transparent member of an inner illumination of a heating cooking apparatus is formed by adhering a support plate to a thermoplastic polyimide film with adhesive, etc. The plate is desirably formed of a stainless steel plate in which a hole is opened at an illumination part. The film is manufactured by a melting extrusion method. The film is adhered to the plate with excellently transparent, heat resistant adhesive such as epoxy series adhesive, silicone series adhesive, etc. Since the film is made of thermoplastic polyimide having a repetition unit represented by a formula I, a decrease in illuminance of the inner illumination of a heating cooking apparatus exceeding 260 deg.C is prevented. In the formula, R is tetravalent group selected from formulae II-VI, X is a bivalent group selected from a group consisting of a direct bond, sulfur atom, sulfone group, carbonyl group, isopropylene group, hexafluoroisopyridene group, and hexafluoroisopyridene group.

Title: Method for writing data in electrically-writable non-volatile memory
Inventor: TANAKA KENICHI
IPC: G11C16/02
Filed: 1987-12-17
Abstract: PURPOSE:To always execute writing with an optimum voltage by executing the writing at a low writing voltage first, checking whether the writing is completed or not, raising the voltage when the writing is failed, executing the writing again, and repeating the writing data until the writing is completed. CONSTITUTION:When the data are written from an external part to a register 1, a controller 5 controls a writing voltage control device 4 so as to output a minimum voltage to be generated, and the writing to a memory cell 2 is executed. Next, the controller 5 controls the memory cell 2 so as to execute a reading, and when a result in which a read resuLt and the contents of the register 1 are compared by a comparator 3 does not coincide, the controller 5 re-controls the writing voltage control device 4 so as to raise the voltage, and the writing to the memory cell 2 is executed. Thereafter, until the compared result coincides, namely, until the data are completely written, the writing is repeated while the writing voltage is successively raised. Thus, the writing with the approximately optimum can be always executed.

Title: Light transmission type liquid crystal display device
Inventor: TOUYA KENJI
IPC: G02B6/00
Filed: 1989-12-11
Abstract: PURPOSE:To reduce the thickness and to perform all operation with one light source by using an optical fiber which has a light leak surface and a fiber plane light source which has a reflecting surface and a light source. CONSTITUTION:The light emitted by the light source 5 passes through optical fibers 3 which are bundled to reach the reverse surface of transmission type liquid crystal 6. The optical fibers 3 have the light leak surface at this part, so light leaks out of the optical fibers 3 and is irradiated by the reflecting surface 4 to irradiate the reverse surface of the transmission type liquid crystal 6. Each optical fiber 3 can be manufactured in thin structured because of its property, so the thickness of the band-like bundled optical fiber 3 is reducible. Since the reflecting surface 4 can be made in thin, the thickness of the illumination light source 5 is reducible. Further, the transmission loss of the optical fibers 3 is small, so only one light source 5 is required.

Abstract: PURPOSE: To enhance the sensitivity of a SVM coil, and efficiently drive at two times the horizontal frequency of the interleaved raster display by causing one of a horizontal deflection coil and a scanning speed modulation coil to have superimposing relationship with the other coil partially. CONSTITUTION: An electron gun 40 equipped with a main horizontal deflection coil 90, SVM coil winding portions 102, 104, and a static convergence magnet tape 52 is relatively positioned along a Z axis 42. The winding 90 of the horizontal coil 90 extends along the inside surface of a deflection yoke liner, and bends along the funnel shape portion of the yoke liner, and extends in a flat shape by the winding 94 of the deflection coil so as to form a loop. The SVM coil is superimposed with the flat rear winding of the horizontal deflection coil in a Z axis direction at the rear portion of the deflection yoke. The SVM coil is superimposed with none of the main portion of an electron gun, the rear end of a core, or the rear portion of a vertical deflection coil.  Thereby, the sensitivity of the SVM coil is increased, and the SVM coil can be excited by a circuit of loosened drive conditions even at the scanning of 2fH.

Title: Device for decomposing hydrocarbon
Inventor: KAWAMURA SATOSHI
IPC: B01D53/86
Filed: 1990-11-27
Abstract: PURPOSE:To realize energy saving and to hardly poison the catalyst by providing a layer packed with granular dielectric material between electrodes which are connected to the discharge power source and have an inlet for hydrocarbon- contg. gas, and providing an oxide catalyst layer having an exit for the gas which is rendered harmless in the downstream of the first layer. CONSTITUTION:A hydrocarbon-contg. gas enters the layer packed with granular dielectric material 6 between the entrance electrode 3 and the exit electrode 4 through the gas inlet 1. An electric field is applied from a power source 5 to the granular dielectric material 6 layer where partial discharge is caused to generate plasma, with which the introduced hydrocarbon is decomposed to produce CO. The produced CO passes through the oxidation catalyst 7 layer provided in the downstream of the first layer and converted to harmless CO2. Then the harmless gas is discharged through the gas exit 2. Thereby, hydrocarbon can easily be decomposed at normal temp. even when the concn. is low, and the process uses small energy, which realizes energy saving. Moreover, since usual poisoning material is also electrolyzed by discharge, the catalyst is hardly poisened.
