Abstract: PURPOSE:To improve atomization and combustion efficiency by providing a notch in a predetermined location of an intake air control-purpose opening/closing valve provided downstream from a throttle valve to close the valve during low and intermediate load and changing the location of the notch in the intake air passage in accordance with engine temperature. CONSTITUTION:An intake air control valve 11 achieves forward rotation and reverse rotation of a valve at the opening/closing time and the closing time of the valve by means of an actuator 20 having a first and second negative pressure chamber 24, 25, the notch 12 of the valve 11 is positioned downward in the forward rotation and is upward positioned in the reverse rotation. The pressure in the negative pressure chamber 24, 25 is controlled by changeover between the negative pressure in direction controlling valves 30, 40 and the atmospoheric pressure. The valve 30 is controlled in response to the engine speed 60 and negagive pressure 61 and the valve 40 is controlled additionally in accordance with the engine temperature 62. At the time of low temperature of hte engine, the intake air control valve 11 establishes its forward rotation and the notch 12 is positioned downward. Furthermore, the air mixture flow is directed to the lower part of a cylinder, smoking of a plug 7 is prevented. At the time of high temperature, the notch 12 is positioned upward and swirl is formed by reverse rotation.

Inventor: NISHIMORI EIJI
IPC: H01L21/331
Filed: 1990-09-03
Abstract: PURPOSE:To reduce the area occupied by a region constituting a ballast resistance and to realize a small-sized IC chip by a method wherein, in place of the ballast resistance constituted of a diffusion resistance, the ballast resistance is constituted of an interconnection resistance. CONSTITUTION:The width of an extraction interconnection 11 at the outside of an emitter contact window 9 is formed to be narrower than the width of the extraction interconnection 11 on the emitter contact window 9. Consequently, it is possible to increase the resistance value of the emitter extraction interconnection 11 in this thin region. While a common emitter interconnection 10 is brought close to a region partitioned by an isolation region 2 as the operating part of a power transistor, the emitter extraction interconnection 11 can be used as a ballast resistance.

Title: Equipment for growing crystals
Inventor: ROKUSHA TOSHINORI
IPC: C30B15/00
Filed: 1991-09-13
Abstract: PURPOSE:To remove and recover SiO generated from molten Si to prevent SiO from sticking to a crucible or a heater by installing a gas absorber, etc., near the surface of the molten SiO when drawing up Si single crystals from the Si melt in the crucible to grow crystals by the Czochralski method. CONSTITUTION:Polycrystalline Si is put in a crucible 11 consisting of a quartz inner layer 11a and a graphite outer layer 11b and heated by a heater 12 to form a melt 17 of the polycrystalline Si. A lifting shaft 14 fitted with Si seed crystal 15 is put down on the surface of the melt 17. The seed crystals 15 are gradually lifted to lift Si single crystals 16 at the tip which are grown. Since SiO is generated from the surface of the molten Si 17 at this time, a gas absorber 25 is arranged on the surface to absorb SiO which is prevented from sticking to the crucible 11 or the heater 12. Since the SiO sticking to the crucible, etc., does not fall on the surface of the molten Si liquid 17 nor does it stick to the heater 12, the Si single crystals 16 during lifting are prevented from being made polycrystals and thermal efficiency of the heater 12 is prevented from being decreased.

Title: Method for manufacturing semiconductor dynamical amount sensor
Inventor: FUJITA MAKIKO
IPC: G01P15/18
Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor dynamical amount sensor, using a new technique requiring no special process, in which a moving part is prevented from fixing on a substrate, even if the surface of the substrate is even, when the moving part of a beam structure is formed by sacrificial layer etching. SOLUTION: A wiring (polysilicon thin film) 2 is formed on a silicon substrate 1 in LPCVD manner. In this case, the formation is performed at a low temperature of about 620 deg.C, so that irregularities are formed on the surface. A silicon oxide film, acting as a sacrificial layer, is formed thereon, and in addition, a polysilicon thin film, as a moving part forming thin film, is formed thereon, and the silicon oxide film under the polysilicon thin film is removed by wet-etching, to form a moving part 5. At this time, a solution displaced with an etchant enters between the moving part 5 and the substrate, and the moving part 5 is pulled by the substrate, but fixing of the moving part 5 is prevented by the irregularities.  And since the wiring 2 and the gate electrode (wiring electrode 2) 10 formed on the surface of the substrate are formed of the same material by utilizing the same process, no special process is required for forming the wiring 2.
