Title: Intake shutter controlling method and device thereof in automatic engine stopping and staring device
Inventor: UMEZAKI KOICHIRO
IPC: F02D17/00
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce operating sound when the supply of intake to an engine is restarted by controlling an intake shutter to open at a speed which is slower than a speed when the intake shutter is closed so that a change of pressure within the engine may be gentle when the engine is restarted after the intake shutter is closed and the engine is stopped. SOLUTION: When an engine 1 is stopped, an intake shutter solenoid valve 9 is switched to a location where compressed air is supplied to an air cylinder 5 based on a command signal 19 from a control circuit 18, a shutter 4 is closed by the elongation of the cylinder 5 and the intake supply to the engine 1 is interrupted. Subsequently, when a clutch pedal is worked, the solenoid valve 9 is switched to a location where compressed air is exhausted from an exhaust port 20 by the control circuit 18 from the output signal of a clutch switch 15. At this time, compressed air is slowly exhausted via an exhaust restriction 21 and a speed reopening the shutter 4 becomes slower than a speed when the shutter is closed. As a result, intake is not rapidly inhaled within the engine 1 and operating sound is reduced.

Inventor: OTA KIYOSHI
IPC: H01L21/208
Filed: 1989-07-14
Abstract: PURPOSE:To form p-type SiC on n-type SiC by a simple process without enlarging a device by laminating a metallic film which reacts intensively with oxygen and an aluminum film thereon on an n-type silicon carbide and by thereafter performing heat treatment for the lamination substrate. CONSTITUTION:An n-type SiC substrate 1 is prepared; an n-type SiC layer 2 is formed by epitaxial growth on one main surface 1a thereof; and a Ti film 3 and an Al film 4 are laminated successively on the n-type SiC layer 2. The lamination substrate is heat-treated in an inert gas of 900 to 1000 deg.C such as Ar atmosphere to allow Al in the Al film 4 to pass through the Ti film 3 and to diffuse inside the n-type SiC layer 2; a p-type SiC layer 5 is thereby formed. An Ni film 6 and an Au film 7 perform ohmic contact for the n-type SiC substrate 1 to become an n-type electrode 8. Accordingly, an SiC semiconductor can be manufactured at a low cost without requiring enlargement and complication of a crystal growth device.

Filed: 1984-09-04
Abstract: PURPOSE:To control the emission of smoke, by deciding the maximum quantity of injection according to the density of oxygen in exhaust gas. CONSTITUTION:The output of an air fuel ratio sensor is decided in a step 209. Then, it is compared with the generated electric current to the over-air ratio lambda=1.2 in exhaust gas, which is the limit of the smoke emission.

In case of lambda=1.2, it is not compensated, and in case of lambda<1.2, it is decreasingly compensated. In this way, the emission of smoke can be controlled, regardless of the change of environmental situation or the change due to time of a characteristic of such as a valve.
