Title: Magnetic recording medium
Inventor: TOKUDA NORIMICHI
IPC: C09D127/06
Filed: 1981-12-17
Abstract: PURPOSE:To provide a magnetic recording medium having excellent dispersibility, surface smoothness and durability by using magnetic paint which contains a special polyurethane resin having extremely outstanding dispersibility and a vinyl chloride-vinyl acetate copolymer having improved dispersibility as binder components. CONSTITUTION:A polyurethane resin contg. -SO3Na groups and a vinyl chloride- vinyl acetate copolymer are used in combination, and are thoroughly dispersed by commonly used methods by using magnetic powder pigments, lubricants and solvents. The mixture is coated on a polyethylene terephthalate film to 5mu thickness after drying and is dried; thereafter, the film is subjected to calendering. When the surface reflectivity of the magnetic coating film of the resultant magnetic recording medium is measured, the improvement in the surface lubricity of the magnetic recording medium is extremely high. If the content of the maleic acid in the vinyl chloride-vinyl acetate copolymer is increased, the surface lubricity is improved further.

Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To prolong the cycle life of a rechargeable battery and improve its discharging capacity by arranging in its casing a negative electrode means with hydrogen storage capacity separated from a positive electrode with a separator. SOLUTION: A negative electrode means, which involves an non-oriented electrode of higher electrochemical charging/discharging efficiency and higher electric generating power, produces the hydrogen storage capacity of the substance totally with the discharging capacity of a longer cycle life. A battery 10 comprises a casing 12 with an outlet 14 adapted to be sealed by welding, a negative electrode 16 formed out of the unordered substance, and a positive electrode 18 typically made of a nickel hydroxide. The negative electrode 16 and the positive electrode 18 are separated from each other with a separator 20 in electrolyte 22 such as KOH. The size, type and capacity of the battery 10 and electrodes 16 and 18 are freely selected depending on their applications.  That situation applies also to the case where the polycrystal is polyphasic; if the negative electrode 16 formed from the non-oriented multi- component substance lacks its long-distance compositional order, the structure may be in combination with at least either of an amorphous type and a microcrystalline type.

Title: Pinhole detecting method of packed product
Inventor: FURUKAWA TAKAO
IPC: G01M3/26
Filed: 1982-11-18
Abstract: PURPOSE:To handle numbers of bags securely and simultaneously by placing packed products under a vacuum and returning them to atmospheric pressure, and detecting whether there is a pinhole or not from whether the packed products deform or not at that time. CONSTITUTION:Packed products A are put in an airtight container B, which is then evacuated by a vacuum pump connected to a port 5. As the pressure P1 in the container B drops, pressure difference from the pressure P2 in the packing materials 2 is generated and if a packing material 2 has a pinhole, its internal gas leaks out. The vacuum pressure P1 in the container B is held at a specific value for a specific time and the inside of the container B is returned to atmospheric pressure through the port 5. Packed products which have no pinhole are still in their original puffy shapes, but the packed product with the pinhole deforms in such a form that the packing material 2 contacts closely to the surface of the packed body 1. Therefore, only the deformed packed product is selected to remove only the defective product with the pinhole.

Title: Fragrant deodorizing composition for feces
Inventor: ARAKAWA TSUTOMU
IPC: C11B9/00
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To effectively deodorize the smell of feces by incorporating a scent glycoside having a β bond of a scent compound and sugar as effective component. SOLUTION: Enterobacterium which produces ammonia, mercaptans, amines and the like regarded as causes of offensive smell of feces efficiently decomposes a scent glycoside having a β bond to generate fragrance by isolating scent components. In view of this, a compound which has scent glycoside in a bond of a scent compound is contained as effective component to prepare a fragrant deodorizing composition for feces. In this process, the blending concentration of the scent glycoside in the fragrant deodorizing composition for feces is not limited because it varies with the threshold of the scent components composing the scent glycoside. But the blending concentration is preferably in a range of about 0.01-30wt.% in terms of the concentration of the scent glycoside in light of preference and fragrant deodorizing action.  The scent glycoside herein applicable has a β bond which is invulnerable to decomposition by a digestive enzyme and is decomposed by the enterobacterium to isolate the scent components.

Abstract: PROBLEM TO BE SOLVED: To prevent a line-to-ground fault and suppress tracking destruction, by preventing a leakage current from flowing. SOLUTION: An annular body 18 is molded integrally of a tracking resistant material such as silicone rubber and has heat contracting property. The annular body 18 is fitted onto each of outer circumferential surfaces 17 of both of fixed electrode tubes 4, 5 and onto an outer circumferential surface 19 of a terminal tube 6, and are made to adhere by taking advantage of the heat contracting property.
