Title: Suction throttling control method for diesel engine
Inventor: NAGASE MASAOMI
IPC: F02D31/00
Filed: 1982-12-27
Abstract: PURPOSE:To reduce idle vibration or noise effectively without sacrifice of fuel consumption performance by detecting variation of idling (or idling vibration) and controlling the opening of a suction throttle valve in accordance with said variation. CONSTITUTION:In idling vibration suppressing method through a sub-suction throttle valve placed in a sub-suction path 18 detouring main suction throttle valve 16, an electronic control unit (ECU) 68 will calculate engine speed NE from the output of engine speed sensor 32. Upon decision of idling, the difference DELTANi between average engine speed and current engine speed NE is obtained and averaged for several times. Then average differential engine speed DELTANi is compared with decision level (for example, 50rpm) and if DELTANi exceeds over decision level, a duty control signal to be provided to a negative pressure exchange valve 70 is reduced by 30%, for example, to control a sub-suction throttle valve 20 in closing direction.

Filed: 1996-09-05
Abstract: PROBLEM TO BE SOLVED: To improve a noise suppressing characteristic by arranging a cutoff device which can be arranged between a noise suppressing body and connecting pipes and is composed of an elastic material. SOLUTION: A cylindrical noise suppressing body 3 has opening parts 9 and 11 in its lengthwise side end part, and connecting pipes 13 and 15 respectively project to the opening parts 9 and 11, and an internal space 17 of the noise suppressing body 3 is constituted so that a liquid medium or a gaseous medium can flow to the inverse side connecting pipe 15 from the connecting pipe 13. A flowing cross section of the noise suppressing body 3 is selected larger than a flowing cross section of the connecting pipes 13 and 15, and the connecting pipes 13 and 15 and the noise suppressing body 3 are joined together by using elastic cutoff elements 5 and 7 formed in a ring shape.  Therefore, the cutoff elements 5 and 7 are formed so that its inside diameter is smaller than an outside diameter of the connecting pipes 13 and 15 and an outside diameter is slightly larger than a diameter of the noise suppressing body 3. When the cutoff elements 5 and 7 are pushed in by elasticity of the cutoff elements 5 and 7 and size selection, shape restraining joining is caused between the noise suppressing body 3 and the connecting pipes 13 and 15, and a fixed propagation sound or transmission of vibration to the connecting pipe 15 from the connecting pipe 13 can be prevented.

IPC: H01L21/31
Filed: 1984-11-09
Abstract: PURPOSE:To curb the emission of impurity material by an impurity-implanted silicon oxide film in a heat treatment process by a method wherein an impurity- free silicon oxide film is formed on the impurity-implanted material filling a groove in a structure incorporating an isolating groove. CONSTITUTION:After the formation of a recess 12 on a semiconductor substrate 11, a silicon oxide film 13 is formed in the recess 12. Next, etch-back is accomplished, rendering the silicon oxide film 13 inside the recess 12 a little lower than the surface of the substrare 11. A process follows of forming a silicon oxide film 14 free of impurities on the entire surface and of effecting etch-back for the removal of the oxide film 14 except the portion in the recess 12. This results in the retention of the impurity-free silicon oxide film 14 in the upper portion of the recess 12. Semiconductor in this design is protected from advance effects during a heat treatment process which in other designs will develop due to emission of impurities out of the silicon oxide film 13 remaining in the recess 12.
