Title: Molecular beam epitaxial growth system
Inventor: SONODA TAKUJI
IPC: H01L21/203
Filed: 1988-02-05
Abstract: PURPOSE:To improve crystalline properties of III-V compound semiconductor by a molecular beam epitaxy method, by pyrolyzing hydrogen compounds of V group elements and separating only produced hydrogen from the above hydrogen compounds by a heated palladium alloy, thereby using the decomposed V group elements and minute V group hydrogen compounds as a V group molecular beam. CONSTITUTION:The temperature of a substrate holder 2 is set so that a GaAs substrate 3 cleaned in advance attains a temperature 620 deg.C. AsH3 12 is introduced, by opening a value 13, into a palladium alloy vessel 14 which attains a temperature 700 deg.C. Introduced AsH3 12 is decomposed in the palladium vessel 14 into As, As2, a small quantity of As4, AsH and AsH3 that can be neglected, and a large quantity of H2. Diffusing through the palladium alloy vessel 14, only decomposed H2 is vacuum-exhausted by opening a valve 15. A valve 16 is adjusted in such a way that the whole intensity of As1, As2, and As4 which are introduced in a vacuum chamber 1 through an introduction tube 17 can be twice that of the molecular beam 5 of Ga on the GaAs substrate 3. Further, Si 18 is used as an n-type dopant and it allows an n-type GaAs to grow.

IPC: H01S5/06
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To improve rectilinearity and lessen the chirping to the light modulation over a wide frequency range including a high frequency range, by reducing the chirping of a semiconductor laser for output by gain saturation effect. SOLUTION: An n-lnP layer 18 is grown on an n-InP substrate, and a grading 17 is made. A light waveguide layer 15b of lnGaAsIP a multiple quantum well active layer 16 are grown, and after etching the active layer, a light waveguide layer 15a of InGaAsP and a p-type InP layer 14 are grown, and a p electrode 13 and an n-type electrode 19 are made. A modulating electric signal is added to a DFB laser 12 for light injection, and modulated light is injected into the DFB laser 11 for output, whereupon the output light of the DFB laser 11 for output changes. By the dependency on the modulated frequency of the quantity of chirping of the obtained output light, the quantity of chirping can be reduced.  By the above, a light injection type of light modulator excellent in rectilinearity of the output light to the input electric signal and extremely small in chirping even if the modulated frequency is enlarged can be materialized.

Title: Cutting tool for thin shaft end
Inventor: MATSUTANI KANJI
IPC: B23B51/00
Filed: 1981-02-26
Abstract: PURPOSE:To obtain a cutting tool possible to chamfer a very thin shaft by constituting a cutter by assembling plural number of specific form cutting tools. CONSTITUTION:The chamfering tool 3 consists on four tool elements 4 being fixed with a square collet chuck or a four jaw scroll chuck from the outside. The element 4 is e.g. a square column having an inclined face of angle alpha against the longitudinal direction of the axis, and cut with the cutting surface which has relief angle of beta to its inclined surface ABCD. In this case, alpha is the chamfering angle of the thin shaft e.g. 45 deg., and the relief angle beta can be small angle if required, and will be made to zero for a thin round shaft. The elements 4 thus constituted is made to make the A-a line coincide with the center of rotation of the tool, and is constituted to make the end face of the element 4 inclined to the direction of the arrow mark. Thus, a tool enabling the chamfering of the very thin shaft by assembling several cutting tools of special forms can be obtained, by assembling several pieces of the specific form tools.

Title: Semiconductor element
Inventor: HAYAKAWA MASAO
IPC: H01L27/04
Filed: 1985-02-13
Abstract: PURPOSE:To enable to easily impress bias voltage on the substrate of a semiconductor element and to contrive to simplify the wiring of the element by a method wherein plural pieces of electrodes for substrate bias impression are formed on the surface of the semiconductor chip, and at the same time, plural pieces of the inner leads, which are connected to plural pieces of the electrodes, are made to mutually short-circuit. CONSTITUTION:Plural bump electrodes 2, 2... for substrate bias impression are equally formed on the surface of a semiconductor chip 1, which is arranged on the film carrier substrate, and inner leads 3, 3..., which are connected to the bump electrodes 2, 2..., are made to mutually short-circuit by a short-circuit pattern 11. Just one inner lead 31 among the inner leads 3, 3... short-circuited is used as the inner lead for external electrode lead-out and any of the other inner leads 3, 3... are made in such a way as not to be led out as the external electrode. In this case, the inner leads 3, 3... are made to mutually short-circuit with just modifying the film carrier pattern forming master and such troubles as an increase in the number of the film carrier forming processes and a complication of the wiring are not generated. By this way, bias voltage can be equally impressed on the whole semiconductor element without being biased, and moreover, the number of the connecting wires to be connected with the bias power source can be done with just one wire and the wiring does not become a complicated one.

Title: Diffusion furnace device
Inventor: IMAMURA TORU
IPC: H01L21/31
Filed: 1986-02-10
Abstract: PURPOSE:To prevent the deterioration of the yield and quality of a product by connecting a closed box including a boat loader inserting and drawing out a semiconductor-substrate susceptor to and from a core tube to an opening section for the core tube, supplying the closed box with nitrogen gas and interrupting an introduction to the core tube of oxygen in air. CONSTITUTION:The inside is kept at positive pressure by nitrogen from a nitrogen-gas introducing opening 4, and a closed box 5 into which external air does not intrude is connected to an opening section 3 for a core tube 2. Since a gas introduced from a gas introducing nozzle 9 during heat treatment flows in the core tube, is discharged from the opening section 3 for the core tube and is discharged to the outside from an exhaust port 11 through an evacuating section 10 for the box 5, the inside of the box 5 is not filled with the gas from the nozzle 9. Nitrogen gas is fed into the box 5 from the introducing port 4 during treatment, and the inside of the box 5 is brought to a nitrogen gas atmosphere. Consequently, the opening section 3 for the tube 2 is interrupted from atmospheric air by the atmosphere of nitrogen gas. Semiconductor substrates 7 are taken out to the outside and loaded onto a susceptor by opening a cover 5a mounted to the box 5, and the intrusion of air is also prevented by nitrogen gas at that time.

Title: Controller for automatic transmission
Inventor: BABA FUMIAKI
IPC: F16H61/00
Filed: 1991-01-29
Abstract: PURPOSE:To ameliorate any starting attending on being oblivious of the release of a hold mode. CONSTITUTION:In a D range hold mode, by way of example, it is fixed to three speeds fundamentally, but in a low speed range, it is set to two speeds as a rule. When a car is stopped in keeping a suchlike D range hold mode set up intact (a step S3), in printing, it is so judged that this case is oblivious of releasing the hold mode, thus the forcible release of the hold mode takes place (a step S5). On condition of this hold mode forcible release, it includes a fact that a load variation is large enough (a step S4). When this load variation is small, it means that a driver will not demand acceleration, so that it is no longer required to release the hold mode daringly. In addition, with this load variation found out, in the case where the hold mode is intentionally released in order to start the car on a snow-laden road, useless forcible release is avoidable.
