Title: Production of curved pipe
Inventor: MORIMOTO HISAO
IPC: B29C39/22
Filed: 1980-07-15
Abstract: PURPOSE: To produce a curved pipe having an excellent surface appearance free of destruction and a good physical property, by winding a material, to be formed, onto the periphery of a plexible cylinder, injecting an expansible resin into the interior of the cylinder, and then heating and forming the material.  
     CONSTITUTION: A beltlike material 2 is spirally wound onto a mandrel 1 and adhered together to form a flexible cylinder 5. A material 7', to be formed, impregnated with a resin, e.g. an unsaturated polyester or the like, is wound though a parting film 6 onto the flexible cylinder 5, to form an uncured material layer 7 to be formed. Thereafter, the flexible cylinder 5 is carried through a heating oven 8 to semicure the mterial layer 7, and cut into pieces hving a fixed length by a cutter 9. Thus, a straight uncured pipe 10 is formed. An expansible resin is then injected into the interior of the cylinder 5 of the pipe 10, and the resin-injected pipe 10 is received in a divisible outside die 12. The rein in the cylinder 5 is expanded, and the pipe 10 is concurrently formed and cured. Thereafter, the cylinder 5 with the foam in it is taken off. Thus, an objective curved pipe is obtained.

Title: Identifying method for casting mark
Inventor: FUJITA TSUTOMU
IPC: G06K9/00
Filed: 1986-04-25
Abstract: PURPOSE:To identify cast marks on the surface of a casting at high accuracy by simple constitution by transferring convex cast marks on the surface of a casting, photographing the marks transferred on the transfer paper by a photographing means and processing them. CONSTITUTION:When a casting is carried by a carrier 1, a head 6 comes down and a casting out mark M on the casting 2b is transferred on a transfer paper 5. After transferring, feeding of transfer paper is started with upward movement of the head 6. On the other hand, while the mark M of the casting 2b is being transferred, a casting mark mark M' corresponding to the mark M of foregoing casting 2a is photographed by a photographing means 7, and photographed mark M' is identified by an image processing means 8. Thus, only the cast mark is transferred in plane on the transfer paper irrelevant to convexity and concavity of the surface of the casting, and distinguishing of shadow of unevenness on the surface of the casting and shadow of the cast mark at the time of image processing is prevented from becoming impossible.

Title: Method for recovering nitrogen gas from air
Inventor: SHIBAJI SAAKAA
IPC: C01B21/04
Filed: 1991-04-03
Abstract: PURPOSE: To produce comparatively high purity nitrogen with a low power consumption without a nitrogen rinsing process by passing high pressure air through a selective nitrogen adsorbing agent for adsorbing, desorbing the nitrogen-containing gas by reducing the pressure, discharging, recirculating the gas for high purification, then repressurizing with high oxygen-containing gas obtained. CONSTITUTION: A feedstock stream is introduced to adsorbent columns 51 to 53 through a compressor B. A water- and carbon dioxide-selective adsorbent is filled in a front half part of the column 51 and a nitrogen-selective adsorbent is filled in the rear half of the column 51, therefore, nitrogen is adsorbed and oxygen passes through. Then the gas proceeds to the column 52 into which only the feedstock stream is introduced in a latter half of the adsorption process in the column 52, while the pressure in the column 51 is reduced for desorbing and discharging. Nitrogen-containing gas flows countercurrently to the feed stock stream passage in the column 51. After a proper period of time, high purity gaseous nitrogen is produced and stored in a storage vessel S. At this point, the column 53 is countercurrently repressurized through a valve 23.

Title: Semiconductor device
Inventor: MORI SHOGO
IPC: H03K17/08
Filed: 1992-04-17
Abstract: PURPOSE:To improve an area efficiency when anti-parallel diodes are contained by forming a second conductivity type semiconductor region of the diode as an anode region. CONSTITUTION:A P<+> type anode region 7 is formed on an epitaxial layer 3. The region 7 isolates a gate region 4 through the epitaxial layer. If a reverse bias voltage is applied between a gate and a source, a surface potential of the layer 3 for isolating the region 4 from the region 7 becomes positive. As a result, a depleted layer of the layer 3 is scarcely extended, and a punchthrough is scarcely generated between the gate and the anode. Accordingly, if the same gate.source withstand voltage is required, a distance between the regions 7 and 14 can be shortened, and an area efficiency can be improved.

Title: Speed controller for motor
Inventor: MOMOSE TETSUO
IPC: H02P23/00
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To surely prevent a step-out under the state in which rotational speed as a synchronous motor, in which speed is controlled on the basis of the rotational position of a rotor detected by a pole position sensor, is open-loop controlled. SOLUTION: In the current-command preparation section (2) 32A of the speed controller 10A for the three-phase brushless motor 1, a revolving field angle θa is corrected so that difference between the revolving field angle θa arithmetically operated from a rotational-speed command ω* and the magnetic axis position of a rotor obtained from a pole-position sensor output PS is less than π/2 when the difference (a torque angle) exceeds π/2, and a current command I2* is generated on the basis of the revolving field angle θa after correction. Consequently, the torque angle can be held at a value less than π/2 in which no step-out is generated. Accordingly, a step-out can be prevented even when load torque is increased.

Inventor: HIRASHIKI KENICHI
IPC: B67D3/02
Filed: 1995-04-24
Abstract: PURPOSE: To make fluid easy to flow out of a liquid supply port without enlarging the shifting stroke of a valve. CONSTITUTION: A cap 41 installed on the tank 39 for reserving water provided with a valve seat 43, where a water supply port 42 is made, in condition of being inclined to horizontal direction. The water supply port 42 is opened and closed from above by the valve 48 of the valve body 44. It follows that a film is made by the surface tension of water, accompanying the opening of the valve 48, but this film is asymmetrical above and below, and the balance is lost, and it is apt to break from the lower weak place where water pressure is applied, so water is easy to flow out from the water supply port 42 without enlarging the shifting stroke of the valve 48.

Title: Electrolyte for driving electrolytic capacitor
Inventor: IMOTO SEIJI
IPC: H01G9/035
Filed: 1989-04-18
Abstract: PURPOSE:To restrain a leakage current from being increased by a method wherein a tetrahydroxybenzoic acid or its salt of a specific amount is added to an electrolyte in which an inorganic acid, an organic acid or one or more kinds of salts of them are dissolved, as solutes, in an organic solvent such as ethylene glycol or the like. CONSTITUTION:Tetrahydroxybenzoic acid or its salt at 0.05 to 5.0wt.% is added to an electrolyte in which an inorganic acid, an organic acid or one kind or two or more kinds of salts of them are dissolved, as solutes, in an organic solvent such as ethylene glycol, monoesters of ethylene glycol, N,N- dimethylformamide, gamma-butyrolactone or the like. A chemical formation capacity of tetrahydroxybenzoic acid or its salt is high and has an action to quickly restore a defective part of a derivative oxide film. As a result, even when a stress is exerted from a lead terminal, the defective part of the oxide film is restored immediately; accordingly, a change in a leakage current is extremely small before and after the lead wire is processed.
