Filed: 1986-02-04
Abstract: PURPOSE:To improve the yield rate at the time of scribing, by forming a fluoric- acid resisting film on the first oxide film of a scribe line part, and etching a second oxide film formed thereon with fluoric acid. CONSTITUTION:A semiconductor layer 2 is formed on a one-conductivity type silicon semiconductor substrate 1 having low resistivity. The layer 2 undergoes thermal oxidation in an oxygen atmosphere, and a first oxide film 3 is formed. A fluoric-acid resisting film 11 is formed on the film 3.

Title: Method and equipment for electrolyzing fluid electrolyte
Inventor: BARUTAA PESHIYUKA
IPC: H02K44/08
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To utilize heat energy with low loss for electrolysis by impressing a magnetic field on an electrolytic cell, forming a relative movement between this magnetic field and a fluid electrolyte and executing the equalizing of the charge necessary for electrolytic reaction by the closed current route between a cathode and an anode.  
     SOLUTION: The electrolyte flows in an electrolyte return line 76 and the AC thereof flows to an evaporator 90. The thermal energy is transmitted from a heat storage medium to the electrolyte 96 in the evaporator 90. The heat storage medium is carried to a second circuit 105 through a light absorber 104 to compensate the heat loss of a heat storage unit 106. The electrolyte stream flows into the electrolytic cell 12. Superconducting magnet coils 40, 42 generate the magnetic field in the electrolytic cell 12 by cooperating with a magnetic circuit 62. Lorentz force parallel with the direction of the perpendicular of the electrode surface acts on the Na +  and OH -  ions included in the electrolyte stream. The Na +  ions move toward the cathode surface and the OH -  ions flow toward the anode surface. The need for a power generator or other electric energy source is eliminated by this process.

Filed: 1992-02-12
Abstract: PURPOSE:To keep a necessary gap between a coaxial connector and a receptacle and at the same time make the height of the coaxial connector installation the same by installing a part which regulates the insertion depth of coaxial connectors in the outer circumferential face of the housing composing a coaxial connector. CONSTITUTION:A coaxial connector 1 is composed of a housing 3, a center socket 22, and an insulating bushing 23, connected with the terminal part of a coaxial cable 10, and inserted and held in the receptacle 2. An insertion regulating part 4 is formed in the outer circumferential face of the end part in the insertion side of the housing 3 wherein the part is like a plate and extended toward the diameter direction at right angles to the insertion direction. Consequently, when the connector 1 is inserted in the receptacle 2, the part 4 comes to touch mechanically the external end face 2a in the insertion side of the receptacle and thus further insertion of the connector 1 is hindered. The regualting part may be formed in the receptacle 2 side instead of the part 4.

Abstract: PURPOSE: To minimize exhausting noise by restraining rapid expansion of exhaust, by arranging such that the exhaust gases are made to pass through cooling water before emission to the atmosphere.  
     CONSTITUTION: When an engine 7 is operating at a low speed, the outboard engine unit is held deep into water to suffer a large backpressure, and therefore, exhaust comes out from an opening on the bottom side of an exhaust introducing pipe 15 or an exhausting hole 36 to an exhaust expansion chamber 16, and after being deflected upwards in the chamber, it flows into an exhaust introducing path 31, and through this connecting hole 32, it is discharged into engine- cooling water in a reservoir 24. And, after passing through the engine-cooling water, this exhaust is discharged into a top space 29, and it is discharged from this space into the atmosphere through a low-speed exhausting hole 34. And therefore, it is possible to control rapid expansion of the exhaust, reduce exhausting noise to low level and improve noise-preventing effect.

Title: Tape winder
Inventor: SAKAMOTO KATSUJI
IPC: H01B13/08
Filed: 1983-02-17
Abstract: PURPOSE:To have a high speed tape winder for electric wires etc. by providing an intermediate roller midway of the tape transport path, and by increasing the tape tension in the portion, where strong wind is applied to owing to operation of the device. CONSTITUTION:Tape 8 from a tape pad 16 is twisted while passing through a hole 49 bored in a wind-breaking disc 35 and a guide roller 36 and drawn out by an intermediate roller 20 and pinch roller to make then reciprocation between a pair of guide rollers 38, 40 of a tension control arm and a pair of guide rollers 39, 41 of said disc 35, and thereafter the tape is wound on a core 11 upon passing through rollers 42, 43, 48. At this time, rotation of said intermediate roller 20 is adjusted so that the control arm 44 is situated in a constant position, and thus good winding on the core is accomplished with a comparatively low tension. Because of higher tension between the tape pad 16 and intermediate roller 20, the tape will be free from influence of possible strong wind owing to high- speed revolutions, that should together with the effect of said wind-breaking disc 35 ensure stabilization of high-speed tape traveling. Thus good tape winding can be performed.
