Title: Control of injection quantity in engine
IPC: F02D23/02
Filed: 1992-03-26
Abstract: PURPOSE:To avoid smoldering of a spark plug effectively even after repetition of starting and stopping in a short time for inspection or the like in a factory, and improve handlability setting a fuel injection quantity in an engine check mode at a reduced value compared to a general control mode. CONSTITUTION:An ECU 50 is composed of a main computer 51 to perform control of ignition timing and control of fuel injection, and a sub-computer 52 to be used specially for performing a knocking detection process. The main computer 51 controls an injector 23 and a spark plug 24 by a main CUP 58 in accordance with a control program in a ROM 59 based on detection signals from an intake air quantity sensor 41 and various data from a RAM 60 and a backup RAM 61. In this case, the main CPU 58 determines if the mode is a general control mode or an engine check mode. Based on result of determination, at the time of the engine check mode, a fuel injection quantity is set at a reduced value compared to that in the general control mode.

Abstract: PURPOSE:To prevent the breakdown strength of a gate oxide film from deteriorating by forming source, drain regions by low dose ion implantation, then covering it with a gate electrode, and forming a high concentration contact region partly on the source, drain regions by high dose ion implantation. CONSTITUTION:Low concentration N-type source, drain regions 9, 10 are formed by ion implanting an N-type impurity under the condition of low dose. The impurity concentrations of the regions 9, 10 of this case become approx. 5X10<18>(cm<3>) of 1X10<19>(cm<3>) or more. A P-type impurity is implanted under the condition of low dose to form low concentration P-type source, drain regions 12, 13. Contact holes 15, 16, 17, 18, 19, 20 are so opened as to expose the partial surface of the region 9 in a silicon oxide film 14. An N-type impurity is ion implanted from the holes 15, 17 to cover the holes 16, 18, 20 to form high concentration N-type impurity layers 21, 22. A P-type impurity is ion implanted from the holes 18, 20 to cover the holes 15, 17, 19, thereby forming high concentration P-type impurity layers 23, 24.

Title: Magnetic bubble detector
Inventor: IWASA SEIICHI
IPC: G11C11/14
Filed: 1981-05-08
Abstract: PURPOSE:To improve the S/N of a detection output, by locating the contiguous two detectors with the prescribed relation to ensure the peak output emerging in every half period of a rotary magnetic field. CONSTITUTION:A detector 15 at which a bubble P arrives first contains the connecting arms at the center and rear parts of a chevron pattern; while a detector 14 contains the connecting arms at the center and front parts of the chevron pattern. In such way, a Nelson type detector is obtained. For the output peaks of different levels within a period of the rotary magnetic field, a large peak follows a small peak and vice versa for the detectors 15 and 14 respectively. Thus large peak values 16 and 17 emerge with every half period of the rotary magnetic field to be detected easily. The S/N is increased double in comparison with a detection per period. As a result, the S/N of the detection output is improved.

IPC: H01L21/027
Filed: 1989-03-20
Abstract: PURPOSE:To stabilize alignment precision by performing alignment after the coating film of a part covering an alignment mark is preliminarily irradiated with light of sensitive wavelength of sensitive material. CONSTITUTION:When sensitive material like resist of an alignment mark part is irradiated with light of sensitive wavelength, colored resist is decolored; the absorbance of resist of high absorbance is decreased; ordinary resist is exposed to light. When, after preliminary irradiaton, light of the same wavelength is projected, the resist does not exhibit the above photochemical change. When light whose wavelength is slightly different is projected, the resist scarcely exhibits photochemical change. As the result of preliminary irradiation, the photochemical change sufficiently progresses, and the resist is stabilized in the state of high transmittance, so that exposure to light and decoloring do not generate in the course of alignment. Thereby unstable elements for alignment are eliminated, and alignment precision is improved and stabilized.

Filed: 1988-03-22
Abstract: PURPOSE:To lower water absorptivity by compounding a specific ratio of a powdery thermoplastic resin with a cement admixture composed of cement, silica, pulp fibers, pigment, etc. CONSTITUTION:The powdery thermoplastic resin is compounded at 3-7wt.% with the cement admixture consisting of the cement, silica, pulp fibers for reinforcement, pigment and other fillers.

The resin is melted to flow by heating at the time of curing so as to flow into the gaps included in the board material when the board material is molded of the above-mentioned compd. and is cured in an autoclave. The resin solidifies in the gaps after the curing. The volume of the gaps is thereby decreased and the closed cells are formed simultaneously in the board material.

Abstract: PURPOSE:To reduce a bite at a shape quick-change section by providing a distance detector measuring the distance from a model face in front of a tracer head in the advance direction, and reducing the feed speed when the fluctuation quantity exceeds a fixed value. CONSTITUTION:Distance data measured by a distance detector 4 at every fine time  t are inputted to a control device, and the fluctuation quantity ¦ l¦/ t is calculated. The fluctuation quantity is 0 at the place where the gradient of a model 1a is not changed, the measured distance is changed from l1 to l2 when a stylus 2 is moved to a point P10 just before the shape quick-change section P11, and the fluctuation quantity becomes ¦l2-l1¦/ t. If this value exceeds the preset value, the control device detects it and temporarily decreases the feed speed of a tracer head 8. When the stylus 2 passes the point P11 and starts to rise on the slope of the model 1a, the fluctuation quantity again becomes 0. When the stylus 2 reaches a point P20 just before a point P21, if the fluctuation quantity again exceeds the preset value, the feed speed is temporarily decreased here.

Abstract: PURPOSE:To reduce junction capacitance, and to increase a voltage gain by providing an n<-> type low impurity-concentration region only on an n-type active- region surface layer section between a gate and a drain and making the exten sion of a depletion layer larger than a section between the gate and a source. CONSTITUTION:Junction capacitance CGS between gate-source 3, 4 and, junction capacitance CGD between gate-drain 3, 5 are shaped to an epitaxial growth layer section having constant impurity concentration, but a section between the gate-drain 3, 5 is formed in structure in which a low impurity-concentration region 10 is shaped. Consequently, only junction capacitance CGD between the gate-drain 3, 5 can be reduced by the elongation of a depletion layer 11 in the low impurity-concentration region 10. As a result, junction capacitance CGD between the gate-drain 3, 5 can be made lower than junction capacitance CGS between the gate-source 3, 4, thus improving the ratio of CGS to CGD. Accord ingly, a junction type field-effect transistor having high voltage gains is acquired.
