Title: Air-fuel ratio controller for internal combustion engine
Inventor: KAWANABE TOMOHIKO
IPC: F02D41/14
Filed: 1985-04-16
Abstract: PURPOSE:To improve drivability at the time of low temperature in an engine, by compensating a desired air-fuel ratio according to engine cooling water temperature, while feedback-controlling the desired air-fuel ratio after compensa tion according to an output level of an oxygen content sensor for an air-fuel ratio in a supply mixture. CONSTITUTION:An valve opening reference period DBASE in a solenoid on-off valve 9 refers to amap from absolute pressure PBA in a suction manifold 4 and an engine speed Ne. And, likewise a desired air-fuel ratio lambdaT is searched. In addition, a cooling water compensation value lambdaTW is calculated out of cooling water temperature Tw, and this compensation value lambdaTW is subtracted from the desired air-fuel ratio lambdaT, setting this down to a new desired air-fuel ratio lambdaT. And an oxygen content lever 14 detected as oxygen content is compared with a level corresponding to the desired air-fuel ratio lambdaT, compensating the valve opening reference period DBASE, thus valve opening time is determined. Therefore, in proportion as the cooling water temperature is lower, the desired air-fuel ratio is compensated to the lean side whereby the combustion state of an engine 5 at low temperature is stabilized so that drivability is prevented from getting worse.

Title: Preparation of semiconductor device
Inventor: SAKURAI JIYUNJI
IPC: H01L21/331
Filed: 1980-06-17
Abstract: PURPOSE:To prevent the self-blending of a buried layer by a method wherein poly- Si is laid on a Si substrate with a dense buried layer and a single crystal is made by selectively applying energy beams in such a way that impurities are diffused into the poli-Si melted out of the buried layer. CONSTITUTION:A field oxide film 12 and an N<+> layer 11 are formed on a P type Si 10, and poly-Si 13 without an additive is placed on the surface, using the CVD method. Next, all the portion excluding the upper part of the N<+> layer is converted into SiO2 14 in order to limit the element region. Then the power and wave length of laser are regulated so that the laser is allowed to irradiate the whole layer 13 and the surface layer 11a of the layer 11 and melt them to form an N type single crystalline layer 13. The thickness of the obtained N layer 15 is not smaller than that of the N layer and the density of the N layer 15 can be correctly determined from the density of the N<+> layer 11 and the volume of the surface layer 11a. After this, an NPN bypolar transistor is made, using the conventional method. With this constitution, since there is no creeping up of the buried layer 11, the layer 15 can be made thinner, while its integration can be improved.

Title: Production of single crystal thin film
Inventor: ASAKAWA TOSHIBUMI
IPC: C30B29/06
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To highly efficiently produce a single crystal thin film. SOLUTION: This method for producing a single crystal thin film comprises irradiating a substrate 11 with SiH3 beams in the vertical direction and further irradiating the substrate 11 with H beans in the direction parallel to the substrate 11, while accumulating silicon on the substrate 11. Thus, the densest direction (111) of the silicon is arranged in the direction of the SiH3 beams, and the channeling direction (110) is arranged in the direction of the H beans. The accumulated silicon consequently grows as a thin film of the single crystalline silicon. The assisting employment of the beams causing the channeling enhances efficiency for the formation of the single crystal thin film. Since the surface channeling is especially utilized, the efficiency is improved.

IPC: H01H50/20
Filed: 1989-03-31
Abstract: PURPOSE:To reduce the lowest operating voltage and improve switch characteristics by cutting the flow of a magnetic flux between a rod supporting a movable contact and a movable iron core by a magnet cutting part. CONSTITUTION:In an electromagnetic switch device 20, a recessed part 21 having an area smaller than the area of the end surface of a rod 9 is formed on the contact surface with the rod 9 of a movable iron core 8. This recessed part 21 forms a magnet suppressing part which partially cuts the flow of a magnetic flux from the rod 9 to the movable iron core 8 through the contact part when the rod 9 is made into contact with the movable iron core 9. Thus, when the movable iron core 6 is in contact with the rod 9, no reduction in magnetic suction force to the movable iron core 6 occurs as the flow of the magnetic flux through this contact part is partially cut, and the lowest operation voltage can be reduced, so that the switch characteristics are improved.

Title: Dichromatic image forming method
Inventor: KUROSAKA HITOSHI
IPC: G03G15/01
Filed: 1984-04-25
Abstract: PURPOSE:To minimize a decrease in the contrast of an electrostatic latent image corresponding to an image of a specific color by forming the electrostatic latent image corresponding to the specific color of an original on a P type photosensitive body by using an N type photosensitive body with a specific installation resistance in combination. CONSTITUTION:The P type photosensitive body 1 which is charged positively is exposed to an image of the complementary color of the specific color of the red part, etc., of the original to form a positive latent image of the specific color, and a latent image with the opposite polarity is formed on the N type photosensitive body 2 which is charged negatively. The latent image of only the red part is formed on the photosensitive body 1 by the synchronous contact rotation of the photosensitive body 1 and 2 for making both latent images coincident with each other. This latent image does not attenuate against initial charging because an earth resistance R of 10<6>-10<12>OMEGA is provided to the photosensitive body 2 to prevent a decrease in contrast; and the image is visualized with red toner and superposed on and transferred to the black toner latent image of a part other than the red part on the other N type photosensitive body. Consequently, the decrease in the contrast of the electrostatic latent image corresponding to the specific color is minimized and the excellent dichromatic image is formed.
