Title: Semiconductor light-emitting device
Inventor: UEMOTO TSUTOMU
IPC: H01L33/28
Filed: 1988-06-30
Abstract: PURPOSE:To obtain a P-type layer capable of emitting light having a short wavelength near the band width without deteriorating characteristics of P-type zinc chalcogenide crystals even if P-type zinc chalcogenide is grown on a P-type III-V compound crystaline substrate by forming the P-type layer such that concentration of acceptors therein has specific distribution. CONSTITUTION:Zinc chalcogenide semiconductor is epitaxially grown on a III-V compound semiconductor substrate 1 by the vapor growth process to provide a P-type layer 2 and an N-type layer 3 in that order. Carriers are injected into the P-type layer 2 to provide a light emitting layer. In a semiconductor light-emitting device thus produced, a high concentration layer is provided between the III-V compound semiconductor substrate 1 and the P-type light emitting layer by increasing the concentration Na of acceptor in the P-type layer 2 so that the high concentration layer has diffusion length shorter than that of a light emitting region. Further, the high concentration layer has distribution of concentration in which concentration is decreased gradually from the interface between the high concentration layer and the III-V compound semiconductor towards the interface of the PN junction. According to an embodiment, P-type ZnSe 2 doped with Li is grown on a P-type GaAs substrate 1 by the MOCVD process. During this process, amount of the Li material supplied is decreased with the passage of time such that concentration Na of the acceptor presents the curve as shown in the drawing.

IPC: F02M25/08
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To make the learning value of an air-fuel correction coefficient quickly follow the change of the air-fuel correction coefficient by operating a purge control valve such that the flow of purged evaporating fuel is increased or decreased in response to the first learning value and, when an internal combustion engine is operated in a transient state, the first learning value is set at the second learning value. SOLUTION: A purge control valve 24 is mounted in a purge passage 23 which is mounted between a canister 21 for adsorbing evaporating fuel generated from a fuel tank 9 and an intake system of an internal combustion engine and which purges the evaporating fuel in the downstream side of a throttle valve 4. An air-fuel correction coefficient is set in an ECU 6 in response to exhaust gas concentration and the first learning value of the air-fuel correction coefficient is calculated during an air-fuel feedback control. The purge control valve 24 is operated so as to increase or decrease the flow of the purged evaporating fuel. The second learning value of the air-fuel correction coefficient corresponding to a transient operation state is calculated when the operation is in a transient state and the first learning value is reset at the second learning value.

Title: Spacer for liquid crystal device and liquid crystal device using same
Inventor: YAMADA TOICHI
IPC: G02F1/1339
Filed: 1993-06-30
Abstract: PURPOSE:To orient liquid crystal molecules perpendicularly and to prevent abnormal orientation of liquid crystal molecules in the interface between the liquid crystal molecules and spacers by coating the surface of the spacer with a thin film consisting of a specified silane coupling material. CONSTITUTION:Halogen atom and/or alkoxy groups in a silane coupling agent 1 are hydrolyzed to produce substd. silanoles 2. In formula, Y represents groups having 1 to 5 Debye units dipole moment. Then the substd. silanoles 2 are condensed to produce a condensate 3. Hydroxyl groups in the condensate form a hydrogen bonded body with hydroxyl groups on the surface of a spacer or surface of a titanium oxide layer formed on the surface of the spacer 4. By heat treating the hydrogen bonded body 5, the bonded body 5 is changed into Si-O couplings which are firmly bonded to produce a bonded body 6. Thus, a thin film produced from the silane coupling agent is formed on the surface of the spacer 4. Thereby, by using this spacer for a liquid crystal device, liquid crystal molecules can be perpendicularly oriented.

Title: Heating device
Inventor: SHIRAKAWA HIDEKAZU
IPC: H01L21/027
Filed: 1989-06-23
Abstract: PURPOSE:To offset the unevenness of heating caused by current density and obtain uniform heating by increasing the resistance value of a thin film resistant heating element with a gradient from an electrode mounted in the center part toward an electrode mounted on the peripheral part. CONSTITUTION:In a thin film heating device after resist application to a semiconductor integrated circuit manufacturing device, a first electrode 41 is provided in the center part of a thin film resistant heating element 30, and a second electrode 42 on the circumferential part thereof. As an electric current radially runs when the first electrode 41 and the second electrode 42 are energized, the current per unit area is densified around the first electrode 41 and coarsened near the second electrode 42. Therefore, the cross section of the thin film resistant heating element 30 is formed in such a manner that the film thickness is thickened near the first electrode 41 and gradually thinned with a gradient toward the second electrode 42 on the peripheral part. Hence, as a resistance distribution in which the resistance value is small near the first electrode 41 and increased near the second electrode is provided, the calorific value caused by a difference in current density per unit area is offset, and uniform heating can be provided.

The Fe, Cr and Ni which are the alloy components of the zircalloy are thereby deposited on the outside surface of the cladding pipe 1 at the time of the negative voltage in the AC voltage and the oxidation is induced at the time of the positive voltage, by which ZrO2 is formed. Further, the Fe, Cr, Ni, etc., deposited on the outside surface of the cladding pipe 1 are uniformly taken into the oxide film and, therefore, the resistance to the nodular corrosion is improved.

Abstract: PURPOSE:To prevent the occurrence of an arc start miss by giving single harmonic motion with minute amplitude to a torch at a welding starting point, returning the torch to the welding starting point when receiving an arc start confirmation signal from a welding machine and moving it toward a next teaching point. CONSTITUTION:When the torch 5 attains an arc starting point P1, an arc start command is transmitted from a controller to the welding machine and the torch 5 once stops at the above-mentioned starting point P1. The torch 5 then starts weaving between P0 separated by the minute distance   (l) and the starting point P1 in the surface to cross almost orthogonally to a weld line 10. When the arc start is confirmed by the welding machine, the torch 5 attains the starting point P1. When the attainment is confirmed, the torch 5 stops weaving operation and starts to travel toward a next teaching point on the weld line. T he arc can be surely started at the welding starting point by destroying a surface insulating coating film of a wire or base metal and reducing contact resistance by the abovementioned weaving.
