Title: Suction system for engine
Inventor: NAGAO AKIO
IPC: F02B31/00
Filed: 1986-03-24
Abstract: PURPOSE:To secure combustibility so favorably as well as to aim at improvement in travelability, by checking the rarefaction of an air-fuel ratio even in a specific driving range at the time of something trouble in a swirl forming device. CONSTITUTION:At the time of transition from the fixed driving range where lean combustion of an air-fuel mixture is not carried out to the specified driving range performing it the other way, a swirl control valve 18 closes a main suction passage 16 and a small quantity of suction air is fed to a combustion chamber from an auxiliary suction passage alone, thereby producing a swirl there, while an air-fuel ratio of mixture is regulated to the lean side by a controller 46. Here, when trouble in a swirl forming device is detected by a swirl valve opening sensor 43 or a swirl valve closing sensor 44 at the fixed driving range, rarefaction of the air-fuel ratio is checked. Therefore, even after transition to the specified driving range afterward, the air-fuel ratio of mixture is not varied at all, there fore like in case of the fixed driving range, favorable combustibility is secured as it is.

Title: Brake oil pressure holding device in two systems
Inventor: TSUKAMOTO KAZUICHI
IPC: B60T7/12
Filed: 1979-05-23
Abstract: PURPOSE: To make easy starting on a slope, by installing in a braking mechanism a brake oil pressure holding device in two systems.  
     CONSTITUTION: An oil pressure check valve in two systems which is in one body with a clutch master cylinder and electromagnetic oil pressure check valves 3 and 4 are piped and connected in two pipe-line systems between a tandem brake cylinder 1 and wheel cylinders 5 and 6. In this arrangement, when a brake pedal is stepped down with an automobile on a slope, the oil pressure generated in the tandem brake master cylinder 1 actuates the front wheel cylinders 5 through an oil pressure check valve 2 in two systems and the electro-magnetic oil pressure check valve 4 and at the same time actuates the rear wheel cylinder 6 through the oil pressure pipe 22 and the electro-magnetic check valve 3 to stop the automobile. After this, when the accelerator pedal is pressed down and the clutch pedal is gradually released, the oil pressure in the wheel cylinders 5 and 6 returns to the tandem brake master cylinder 1 through the piping 10 and 19, which makes the starting easy by keeping the automobile from moving backward.

Abstract: PURPOSE:To reduce the number of contacts by taking the substrate as the source and to increase the degree of integration, by obtaining sufficient gm, small junction capacitance and high dielectric strength, through the use of DSA technology to the stack gate type non-volatile memory device. CONSTITUTION:The N<-> epitaxial layer 28 is laminated on the N type substrate 27, and oxide film 32, nitride film 31, and oxide film 30 are laminated. The films 32 to 30 are opened, B diffusion layer 44 is formed, and field oxide film 43 and gate oxide film 39 are formed. The polycrystal Si floating gate is selectively formed, and the polycrystal Si control gate 42 is formed via the second gate oxide film 40. Next, ion injection is selectively made, and P layer 35 is formed deeper than the N<-> layer 28. The N<+> source 37 and drain 38 are formed inside and outside the layer 35, and the electrode 45 is attached. Since the N<-> layer 28 is in contact with the layer 35 being channel, the dielectric strength is high, junction capacitance is small, and since the current flows from the source 37 to the substrate 27, the source connection hole and electrode are unnecessary, to increase the degree of integration.

Filed: 1983-04-15
Abstract: PURPOSE:To obtain an inexpensive pattern defect inspecting device which inspects an extremely small pattern by comparing a signal generated by delaying the output signal of a line sensor by a specific time with an input signal, and adjusting the delay time at specific intervals of time. CONSTITUTION:One line sensor 10 is used for an image pickup system, a body 4 to be inspected is mounted of a moving table, and it is moved at uniform speed in right angle to the scan of the line sensor in the visual field of the line sensor 10. At this time, the body 4 to be inspected is fixed to the moving table 6 while coinciding accurately with the moving direction of the moving table 6. The output signal of the line sensor 10 is inputted to an A/D converter 11, and some of its output signal S11 is delayed partially by the specific time through a delay circuit 12 and compared with the signal S11 by a comparing circuit 13. A position shift detecting circuit 18 detects variation in the speed of the moving table and its spatial shift due to inclination in the moving direction to adjust the delay time of the circuit 12 at specific intervals of time. Thus, a dissidence output is obtained from the circuit 13 to decide on a defect part precisely.

Title: Opening and closing mechanism of windowpane
Inventor: MATSUNAGA NOBUHITO
IPC: B60J1/17
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To ensure a smooth upward/downward opening and closing by attaching a carrier plate at a lower edge of windowpane, connecting an upward moving wire to a position being offset forward or rearward from the center of the plate, and connecting a downward moving wire to a position being offset rearward or forward therefrom. SOLUTION: When a drum 19 is rotated normally, a carrier plate 13 is pulled downward by a wire 15 and then a windowpane 11 is moved downward and opened. When the drum 19 is rotated reversely, the plate 13 is pulled upward and then the windowpane 11 is moved upward and closed. The tensile forces of the wire 15 in the upward and downward directions act to the positions 13C, 13D being offset forward or rearward from the center line. At the time of downward movement of the windowpane 11 the counterclockwise rotational force is applied to the plate 13 while at the time of upward movement thereof the clockwise rotational force is applied thereto. As a result, play between the plate 13 and a rail 14 is reduced, thereby generating no stress centering part, leading to prevention of wear of glass run.

Title: Method and device for exposure and manufacture of device using it
Inventor: TOKUDA YUKIO
IPC: G03F7/20
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To improve the alignment accuracy of a reticle and a substrate to be exposed by calculating the heat absorbing rate and quantity of exposed light of the reticle and nonlinear distortion component of a pattern on the reticle and deciding a condition under which the nonlinear strain component exceeds a prescribed amount, and then, refixing the reticle when the condition is met. SOLUTION: A wafer 2 is set on a vacuum chuck stage 1 and entirely exposed by successively exposing a plurality of spots of the wafer 2 by repeating step-and- exposure operations with an X-Y stage. An exposing device which repeatedly performs such a series of operations estimates the temperature rise of a reticle 6 due to the environment around the reticle 6 from the light absorbing rate of the reticle 6 decided in advance by measurement, cumulative exposure by the light energy actually projected upon the reticle 6, and the temperature rise of the reticle 6 due to the environment, etc., around the reticle 6 and, when it is judged that the temperature of the reticle 6 reaches or exceeds a prescribed value, the exposing device judges that the distortion in the reticle 6 exceeds an allowable limit and refixes the reticle 6 after releasing the reticle 6 once.
