Title: Control method of engine
Inventor: NAKATANI MITSURU
IPC: F02D45/00
Filed: 1994-04-27
Abstract: PURPOSE:To prevent various vehicle thermal damages caused by racing and the like by detecting, engine condition when a vehicle is stopped, from both of the temperature of exhaust gas passing a catalyst and engine rotating speed, so as to forcibly reduce the engine rotating speed when high rotating condition continues for a prescribed time. CONSTITUTION:Signals from a crank angle sensor 31 and an intake air amount sensor 10 are read, in an ECU, and engine rotating speed and a catalyst passing exhaust gas temperature when a vehicle is stopped are detected. When the engine rotating speed exceeds fuel cut rotating speed, the duration in high rotation condition is counted. When the duration continues longer than an allowable duration which is set on the basis of the engine rotating speed at the time of high rotation, the fuel is cut, and the engine rotating speed is transferred to a low rotating side. When a differential temperature between the catalyst passing exhaust gas temperature and a normal time catalyst passing exhaust gas temperature exceeds a misfire judging reference temperature width, fuel is immediately cut, and the engine rotating speed is controlled so as to transfer to a low rotation side forcibly.

Abstract: PURPOSE:To prevent stress and breakdown of a gate oxide film due to static electricity and to improve yield and reliability of products, by introducing a dopant for forming source and drain regions through a metallic film for preventing storage of charges. CONSTITUTION:After an N well 2 is formed in a P-type semiconductor substrate 1, an active region is formed by an element isolating oxide film 3 and a gate oxide film 4 is adhered on the surface. A gate oxide 5 is formed of a polycrystalline silicon film and a silicon oxide film 6 is deposited on the surface thereof for protecting the same. A metallic film 7 of a high-melting metal or a silicide thereof for preventing storage of electric charges is deposited and the P-channel MOS transistor region is masked with a photoresist film 8. N-type dopant ions are implanted through the metallic film 7 so that N-type source and drain regions 9 are formed for producing an N-channel MOS transistor QN. In this manner, charge around the gate electrode is not stored in the gate electrode 5 and dielectric breakdown of the gate oxide film can be effectively prevented.

IPC: F15B15/12
Filed: 1979-07-17
Abstract: PURPOSE: To improve the sealing effect of a sealing vane, by employing a simple construction in which an aslant enlarged portion is provided at each inner corner of a gate-shaped seal of an integral structure and corresponding aslant bearing surfaces are formed on a vane supporting the seal.  
     CONSTITUTION: At the seal-mounting position S of each rotary vane 2, is provided an aslant enlarged portion 11a of a greater thickness on each inner corner of a gate- shaped seal 11 of an integral structure to transmit a load between the top wall 11b of the seal 11 and its respective side wall 11c of the same. In addition, an aslant bearing surface 10a' is provided on a vane 2, which supports the seal 11, in contact with its corresponding enlarged portion 11a. When a rotor 3 is assembled in a housing 1, the seal 11 tends to expand upwardly and toward both sides as it protrudes a little from its repsective groove. This expansion improves considerably the sealing function between the outer circumferential and side faces of the rotary vane 2 and the housing 1.

Title: Flat film formation by plasma cvd
Inventor: FUKUDA TAKUYA
IPC: H01L21/31
Filed: 1987-04-15
Abstract: PURPOSE:To increase the speed of forming a flat film by a plasma CVD method by a method wherein, when the film is formed by the plasma CVD method, first of all the surface of an electric conductive material is covered with an insulating film. CONSTITUTION:A high-frequency electric field is impressed to a substrate which is placed on a substrate support stage 9 and which has an electric conductive material on the surface or to a grid which is installed in the neighborhood of the substrate by using an alternating-current wave impression apparatus 10; a film is formed by a plasma CVD method where a directional etching method of a deposition film is overlapped. During this process, first of all the substrate is covered with an insulating film; then, the electric field is impressed and a flat film is formed. By this setup, because the electric conductive material is not exposed directly to a plasma in the plasma whose ionization degree is high, a local electric discharge which is bigger than the breakdown strength of the insulating material is not generated even when a bias potential is impressed to the substrate. By this setup, it is possible to increase the speed of forming the flat film by the plasma CVD method.

Abstract: PROBLEM TO BE SOLVED: To improve a service to passengers by a method wherein a landing error during landing of an elevator is set within an allowable range. SOLUTION: A car floor displacement computing means 3 computes a sink amount (a car floor displacement amount) due to a load in a car and a call computing means 4 estimates the number of passengers riding out from a car 5 based on the number of car calls.

Abstract: PURPOSE:To extract an output signal with an optimum level without any waveform distortion or the like within a range of power voltage by providing a control signal generating means and a level control signal so as to control the level of the input signal in response to fluctuation of the power voltage, especially power save in battery drive. CONSTITUTION:When a power voltage Vcc varies due to consumption of a battery 35, the change is applied to a comparison voltage generating circuit 53 of a control signal generating circuit 52. In the circuit 63, a comparison voltage VR representing a level change in the power voltage Vcc is generated. A comparator 54 compares levels of a comparison voltage VR in response to the power voltage Vcc and an output signal Vo. The voltage fluctuation is converted into a control signal Vc having a slow DC level change via a smoothing circuit 55. Thus, since an impedance in response to the control signal Vc is set to a variable impedance circuit 51, an input signal VIN whose level is controlled in response to the power voltage Vcc and the output signal Vo is fed to a preamplifier 50.

Abstract: PURPOSE:To enhance the reliability of original text sheet transporting performance by putting a conductive backup roller in pressure contact with the part where the transport path is bent with the heading changed, in the position of a separating means downstream the nip part of a lower transport member and an upper stop roller. CONSTITUTION:With frictional separating action of a stop roller 222, original text sheets D stacked on a stacker are transported one after another from the undermost one D by means of heaved running of a pushout belt 220 due to rotation of a semicircular roller 228 and running of a sheet feed belt (lower transport part) 221.
