Title: High withstand voltage semiconductor device
Inventor: MUKAI KANJI
IPC: H01L29/74
Filed: 1983-05-17
Abstract: PURPOSE:To improve the withstand voltage of a semiconductor device by setting the interval between a field plate electrode contacted with an elomitter diffused region and a field plate electrode contacted with a base diffused region to a specific value or lower. CONSTITUTION:In a vertical N-P-N transistor formed by planar process by an n type silicon single crystal substrate 15, an interval between the field plate electrode emitter field plate 11 contacted with the emitter diffused region 17 and a field plate electrode (base field plate) 13 contacted with the base diffused region 16 is set to 10mum or less. Thus, in an N-P-N type transistor, when a positive voltage is applied to a collector electrode 10 and a negative voltage is applied to an emitter or base field plate, spatial charge layer 19 is produced, the emitter and base field plates alleviate the electric field concentration in the spatial charge layer by increasing the spatial charge along the oxidized film 14, thereby increasing the withstand voltage.

IPC: F02B75/12
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To suitably inject fuel at all times even in an unstable condition of fuel pressure when cranking is started by correcting a fuel injection timing according to fuel pressure when the cranking is started, in an inter cylinder fuel injection type engine wherein high pressure fuel is injected into a cylinder by a high pressure fuel pump. SOLUTION: When an engine start switch 102 is turned on, output signals of a fuel pressure sensor 106, an engine rotating speed sensor 90, and the like are inputted to a control device 29, and a fuel injection time and a fuel injection timing are corrected according to detected fuel pressure. Namely, correction is carried out for advancing at least a fuel injection timing, and an output is carried out to a fuel injection valve 13 so as to extend the fuel injection time as fuel pressure is small as necessary. This correction is advanced by cranking, it is carried out at any times as cranking rotating speed is increased, and the correction is finished in the case where engine rotating speed exceeds a prescribed value. Fuel pressure is increased to the maximum level when the cranking is started so as to improve operating feeling and an exhaust gas characteristic.

Filed: 1981-06-04
Abstract: PURPOSE:To permit free selection of the position of a metering device and to eliminate  the need for protection against hot wind in a fluidized bed roasting device for powder  and granules by connecting the metering device for the powder and granules and the  roasting devices by means of a pneumatic conveyor. CONSTITUTION:Hot wind is blown through a hot wind supply duct 9 into the hot wind supply ports 13 of two units of roasting vessels 2, 2, and the powder and granules  to be roasted are supplied alternately to the vessels 2 by a selection valve 17, whereby  they are roasted. In this case, a metering device 13 is installed in the lower part of a  storage tank 5 for raw materials powder and granules 14, and the powder and  granules 14 metered to a constant weight are supplied by the compressed air A by a  blower 16 to the valve 17 through a pneumatic conveyor 15. Since the supply of the  powder and granules is transported pneumatically without using gravity, there is no  need for placing the position of the tank 5 provided with the metering device right  above the vessels 2 and the height of the entire part of the device can be made low.  Since there is no influence of the high temp. waste gas from the vessels 2, the need for  heat resistant installations for the metering device is eliminated.

IPC: G04B19/28
Filed: 1985-04-23
Abstract: PURPOSE:To assure substantial air-tightness even in the rotating state and to stabilize the rotating torque of a rotary bezel by subjecting both or either of the surface of a base band which contacts with an elastic sealing member and the surface of the rotary bezel which contacts with the elastic seal to 'Teflon(R)' resin coating. CONSTITUTION:The elastic sealing member 109 is pressed and disposed between the case band 110 and the rotary bezel 107 to provide commonly the effect of preventing the intrusion of dust, dirt, moisture, etc. and the effect of applying adequate rotating torque to the bezel 107. The contact surfaces of the bezel 107 and the member 109 are thereupon subjected to the 'Teflon(R)' coating 115, by which the coefft. of friction on the contact surfaces of the member 109 and the bezel 107 is decreased and the partial elongation of the member 109 is decreased. The air-tightness is thus assured even in the rotating state of the bezel 107. since the interference of the member 109 can be set as large as the decreased amount of the coefft. of friction, the fluctuation of the rotating torque by the variance in working accuracy is suppressed and the rotating torque is stabilized.
