Title: Inorganic nonaqueous electrolyte battery
Inventor: HISATOMI KAORU
IPC: H01M50/426
Filed: 1989-04-28
Abstract: PURPOSE:To obtain an inorganic nonaqueous electrolyte battery whose close circuit voltage drop attendant on storage is small and internal short circuit occurrence rate is low by using an ethylene-tetrafluoroethylene copolymer microporous film as the separator. CONSTITUTION:An oxyhalide which is a liquid at normal temperature is used as a positive active material and the solvent of an electrolyte 5. A negative electrode 1 made of an alkali metal and a positive electrode 3 comprising a carbon porous molding are used. An ethylene-tetrafluoroethylene copolymer microporous film is used as a separator 4. The ethylene-tetrafluoroethylene copolymer has good oxidation resistance and its mechanical strength is not decreased even if it is stored for a long time or at high temperature. The separator can retard transfer of carbon particles toward the negative electrode 1 even if vibration is applied to a battery. An inorganic nonaqueous electrolyte battery whose close circuit voltage drop attendant on storage is small and internal short circuit occurrence rate is low even when vibration is applied can be obtained.

Title: High heat-resistant multilayered magnetic film and magnetic head using the same
Inventor: NAKAMURA HITOSHI
IPC: H01F10/30
Filed: 1990-04-27
Abstract: PURPOSE:To obtain multilayered magnetic films having high thermal stability and high saturation flux density by using a material which little affects the saturation flux density of a film and hardly separates out gamma-phase for the intermediate layer in a multilayered film consisting of a main magnetic film made from a FeC, FeB, or FeN alloy thin film and the intermediate layer of specified nm thickness. CONSTITUTION:Any multilayered film of FeC, FeB, and FeN with a intermediate layer film thickness of about 2-10nm needs to have a 20% or less of gamma-phase separating out in a film to provide a film excellent in soft magnetic characteristics. Examination of the relation soft magnetic characteristics, saturation flux density, and intermediate layer composition after heat treatment of a multilayered film which uses an alloy thin film of Fe95C2Hf3 for the main magnetic thin film and that of Fe-Hf or Fe-Ta proves that multilayered films made of the intermediate layers with elements of body-centered cubic structure such as Fe-Hf, Fe-Ta which hardly generate gamma-phase loaded to Fe both show soft magnetic characteristics and high saturation flux density when loadings exceed 5at%.

Title: Preparation of hollow ball for grinding mill
Inventor: SOGOU HIROSHI
IPC: B02C17/20
Filed: 1979-08-31
Abstract: PURPOSE: To enable a hollow ball to sufficiently cope with the stress applied upon the same by differing the cooling rate between the outside circumferential surface and the inside circumferential surface after the casting of the hollow ball thereby forming compressive residual stress centering at the corner parts of the holes for casting.  
     CONSTITUTION: A hollow ball 1 is annealed after casting, and the cooling medium such as air in an air feed pipe 8 is spouted from the small holes 9 at the ends formed on the circumferential surface of the holes 2 for casting right after it is taken out from a heat treating furnace, whereby the portions centering at the corners 7 are cooled quickly. The outside circumferential surface of the hollow ball 1 gradually cools on account of heat radiation into the atmosphere. As a result, a large temperature difference is produced between both, and upon ending of the cooling, the compressive residual stress is formed at the corners 7. Hence, even if tensil stress is applied to this hollow ball 1 centering at the holes 2 for casting in grinding process, it is offset by the compressive residual stress and no cracking is caused in the ball 1, thus its life is prolonged.

Title: Electronic sealing display system
Inventor: GOTOU YASUKO
IPC: H04L9/32
Filed: 1987-05-08
Abstract: PURPOSE:To visually recognize a digital signature using the RAS open cryptographic key by showing a random bit train in KANJI (Chinese characters) and colored bar codes. CONSTITUTION:A digital signature using the RAS open cryptographic key is equal to a random bit train including 512 bits. This bit train is divided into blocks of a fixed number (16) of bits and these divided bit trains are checked for each block. When a bit train corresponding to KANJI codes is detected, it is replaced with the corresponding KANJI [such as figure (o), (p)] and displayed. A block containing no corresponding KANJI code is divided into bit patterns every 4 bits and replaced with 16-colored bar codes set previously in response to bit patterns every 4 bits for display. Thus it is possible to provide the visual recognizing performance to the digital signature of a random bit train and to easily discriminate this signature from other digital signatures.

Title: Method and system for supplying electric power to electronic facility
Inventor: GABILLET JEAN-PAUL
IPC: H02J9/06
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To provide a power system which is less expensive than the conventional system, by directly supplying electric power to an electronic facility from a main power source under a normal condition or from a second power source under a backup condition, in combination with individual power converters which feed internal power required by each equipment of the electronic facility. SOLUTION: A main power source is composed of a low-voltage main power source 31 or a generator set 32 and directly supplies electric power to a power distribution bus 33 in a normal mode. The bus 33 itself supplies electric power to converters corresponding to various equipments 341 -343 of a remote communication facility through individual specific exclusive converters 351 -353 . In a backup mode, in addition, a change-over switch 36 switches the power source to a battery 37 so that electric power may be supplied to the bus 33 from the battery 37. Thus, the converters 351 -353 can switch either an AC voltage or a DC voltage. A power system thus constituted is profitable in the cost, conductor size, compactness, etc.

Title: Suspension apparatus for fine dust
Inventor: YUNOGAMI SABURO
IPC: B08B15/00
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To prevent the scattering of fine dust without requiring a scrubber containing a filler by arranging nozzles for ejecting water into an exhaust gas pipe spirally on the periphery of the exhaust gas pipe. SOLUTION: The scattering of fine dust from an exhaust gas opening 10 is prevented by using mixing water 6 for converting the fine dust into slurry. In other words, jet nozzles 11 which spray water in a fan shape are arranged spirally in an exhaust gas pipe 1 which is installed to communicate with the exhaust gas opening 10, and jet water branched from the mixing water 6 is supplied to the jet nozzles. In this way, the cross section of the exhaust gas pipe 1 is covered almost completely. Since atomized jet water and fine dust which is dropped by the jet water fall into a suspension tank 2, the total quantity of the mixing water 6 is not increased so that desired suspension can be obtained without adjusting the quantity of the fine dust or the mixing water 6.
