Title: Control device for engine
Inventor: KIMURA OSAMU
IPC: F02M69/00
Filed: 1992-02-06
Abstract: PURPOSE:To reconcile the prevention of the fuel adhesion to a cylinder wall surface accompanying the enhancement of a swirl and the prevention of the swirl damping accompanying the supply of assist air in a engine which generates an intake air swirl in a combustion chamber. CONSTITUTION:An air assist type fuel injection valve is provided downstream from a control valve on non-swirl port side. By closing the valve to introduce intake air only from a swirl generating port, a swirl area (A area) for generating an intake air swirl in a combustion chamber is judged (S2), and the supply of assist air is stopped in the swirl area (S3). Thus, the adhesion of fuel to a cylinder wall surface along the swirl can be prevented, and the damping of the swirl caused by the inflow of assist air from a non-swirl port can be prevented.

Title: Low power cmos integrated circuit
Inventor: HORIGUCHI SHINJI
IPC: H03K19/00
Filed: 1984-02-10
Abstract: PURPOSE:To reduce or prevent the through currents in a back-up mode by setting the threshold voltage VTN of an n-MOSTR at a high level and the threshold voltage VTP of a p-MOSTR at a low level respectively only in the back-up mode. CONSTITUTION:A CMOS inverter shown in the diagram is driven by a power supply 1 in a normal mode, and VTN-VTP<¦V1¦ is satisfied between the voltage V1 and threshold voltages VTP and VTN of MOSTRs 3 and 4. In this case, the static characteristics of the inverter are equal to those of a conventional type. When the power supply 1 is not applicable, a current is supplied automatically from a power supply 2. The voltage V2 of the power supply 2 is set lower than the voltage V1 to satisfy VTN-VTP>¦V2¦. Thus the TR3 conducts only when 0<=V1n<=V2-¦VTP¦ is satisfied: while the TR4 conducts only when VTN <=V1n<V2 is satisfied. Therefore both TRs 3 and 4 are not conductive when V2-¦VTP¦<V1n<VTN is satisfied. Thus no through current flows.

Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To etch a desired part of a silicon nitride film by etching the surface of the silicon nitride film with plasma containing oxygen as a main component before a resist pattern is formed after the silicon nitride film is formed. SOLUTION: A silicon substrate 10 on which a silicon nitride film 13 is formed is set on an etching device and the surface of the film 13 is etched. Since the etching device is provided with a charge trap, most of the material reaching the surface of the film 13 during the etching operation is oxygen radicals. Since the surface of the film 13 is etched with the oxygen radicals, a fluorine-containing material 13 is etched off. After etching, a resist pattern is formed on the silicon nitride layer 13b so as to use part of wiring 12 as an electrode. Therefore, a desired part of the film 13 can be etched without leaving any etch residue without receiving any influence from impurities which deposit when the film 13 is formed.

Abstract: PURPOSE:To reduce failures caused by wear by providing both a leaf spring which forces both the inclined faces of a power transmitting valve body and a vacuum maintaining valve body against each other and a resilient element which forces both the transmitting valve body and the maintaining valve body to separate from each other. CONSTITUTION:With a valve 41 closed, a driving power transmitting valve body 29 is pressed downwards so that the inclined face 29b of said valve body 29 presses the inclined face 33b of a vacuum maintaining valve body 33. In order to open the valve so that a driving shaft 14 is driven upwards, the transmitting valve body 29 activates to be released from the intermediate position between the leaf spring 36 and the maintaining valve body 33 so that the inclined face 29b and the slope face 33b of the maintaining valve body 33 slide on each other via metal balls 32 and 35. When the transmitting valve body 29 is moved upwards, the pressing force of a spring 39 is weakened. The maintaining valve body 33 is then quickly attracted to the transmitting valve 29 by the resilient force of the leaf spring 36.
