Title: Mis type field-effect transistor
Inventor: ARAI KATSUJIROU
IPC: H01L29/423
Filed: 1989-02-17
Abstract: PURPOSE:To offset the stress of a silicide film and the stress of a silicon nitride film and to prevent the releasing phenomenon of a gate electrode by coating the upper surface of a polycide gate electrode with silicon nitride. CONSTITUTION:A gate oxide film 5 is selectively formed on the surface of one conductivity type semiconductor substrate 1. A polycrystalline silicon film 6, a gate electrode comprising a tungsten silicide film 7 and silicon nitride film 8 are sequentially laminated on the film 5. A silicon oxide film 9 for the side wall is formed on the side surface of the gate electrode. The tension for the silicide film 7 in the tensile direction is increased when the content of the silicon in the film 7 is low and heat treatment is performed. Meanwhile, stress in the compressing direction acts on the silicon nitride film 8. The two formed films 7 and 8 are directly brought into contact, and the stresses in the reverse direction are eased. Thus, the releasing phenomenon after the formation of the gate electrode can be prevented.

Title: Operation curve producing method for train
Inventor: YAMAGUCHI FUMITOSHI
IPC: B61L27/00
Filed: 1991-02-12
Abstract: PURPOSE:To provide a train operation curve producing method which improves operability and approximately automatically and rapidly produces an operation curve. CONSTITUTION:An operation curve producing method for a train comprises a step S1 wherein a terminal point speed at a downward slope forms a limit speed and a notch-off limit curve is produced by effecting calculation in a direction reverse to the running direction of a train, a step S2 wherein a brake limit curve is produced by calculating in a direction reverse to the running direction of a train so that when the running brake of a train is applied, a train speed attains a target value in a target position; and a step S3 wherein an operation curve is produced based on the notch-off limit curve and the brake limit curve. The change in an operation speed of a train is simulated based on each limit curve, and an operation curve is approximately automatically produced as it is confirmed that a speed does not exceed a limit value.

Title: Vacuum pump
Inventor: TSUKUDA SADAAKI
IPC: F04B37/10
Filed: 1983-03-11
Abstract: PURPOSE:To greatly reduce piston volume by forming a discharge valve with a through hole provided in a piston and a U-shaped notch of a diaphragm, so that the assembling process of the piston into the valve may be eliminated. CONSTITUTION:As a piston is forced in, and the volume of an airtight chamber is expanded, gas pressure is lowered to open a suction valve 8, allowing air intake inlet part gas to flow into the airtight chamber. Then, when the piston 3 moves downward, the suction valve 8 changes to a released state to permit it to be closed, and thereby the volume of the airtight chamber is redued, allowing the gas pressure to rise. And, a discharge valve 231 is inclined toward a valve due to the difference against the gas pressure at the discharge inlet part guide, allowing gas in the airtight chamber to flow out to a chamber formed by a bonnet 7 through a venting hole.

Title: Forming method for fluorescent screen of cathode-ray tube
Inventor: TANNO SEIKICHI
IPC: H01J9/227
Filed: 1978-04-05
Abstract: PURPOSE: To secure the simultaneous formation of the fluorescent film and the resin film to (formed on) the fluorescent film by mixing the acrylic  monomer into the fluorescent slurry.  
     CONSTITUTION: The mixture material obtained by mixing one or more than one kinds of acrylic monomers shown by the general formula (Eq. I, where X is H, and CH 3  and R are alkyl groups C 1 WC 8 ) of the vinyl monomer and one or more than one kinds of the oil-soluble polymerization initiator or the water-soluble polymerization initiator is mixed into the water-soluble fluorescent slurry. With formation of the fluorescent film via such slurry, the monomer is isolated in the drying process of the film and floats up to the upper part of the fluorescent film because of its specific gravity smaller than the water. After this, the monomer is polymerized through the heat treatment at 70°C or higher. As a result, the resin film is formed on the fluorescent film to be used as the filming film

Abstract: PROBLEM TO BE SOLVED: To separate, from contents, moisture, oil, juice or the like generated from the contents by forming a dent on a base or on the base and on a side wall and providing a gas-permeable sheet layer to form a void on an upper surface of the dent. SOLUTION: Groove-like dents 2 arranged in parallel are formed on a base of a container body 4 of a tray 1. A gas-permeable sheet layer 5 comprising non-woven fabric is provided along an entire periphery of an internal wall surface of the container body 4. A void 3 is formed in the dent 2 by preventing the sheet layer 5 from coming into tight contact with the container body 4 on the dents 2 on the container base. This constitution allows moisture, oil or drips like juice generated from contents in a container to be reserved in the voids 3. The drips reserved in the voids 3 may be separated from the contents via the gas-permeable sheet layer 5, whereby a taste of the contents may not be degraded and decay can be prevented from advancing.
