Title: Polymer of novel vinyl compound
Inventor: SUGIMOTO RYUICHI
IPC: C08F30/08
Filed: 1987-04-03
Abstract: PURPOSE:To obtain a polymer expected to be useful as a reactive polymer or heat-resistant polymer taking advantage of the particular nature of carbon- silicon bond, by using constituent element comprising a novel vinyl compound containing silicon as a ring component. CONSTITUTION:The objective polymer contains a novel silicon-containing vinyl compound of formula (R is H or hydrocarbon residue) as a constituent element. The novel vinyl compound of formula can be easily produced e.g. by reacting a dihalogenated vinylsilane of formula C2H3-SiRX2 (X is halogen) with a Grignard reagent derived from 1,5-dihalogenated vinylsilane. The objective polymer is produced by polymerizing the vinyl compound produced by the above process or copolymerizing the vinyl compound and other copolymerizable monomer in the presence of an anionic polymerization initiator (e.g. butyllithium) and a catalyst composed of an organometallic compound.

Title: Polyvinyl alcohol film sealed-part and heat seal method
Inventor: KAGEYAMA YOHEI
IPC: B31B50/64
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To provide a heat sealed part free of damage to sealed-part surfaces due to heat and provide a highly-speedy, steady, consecutive heat seal method which prevents resin from sticking to a heat plate, in the heat sealing of polyvinyl alcohol films. SOLUTION: In the part where polyvinyl alcohol films are sealed together, the sealed part is free of thermal history on the outsides of the films which is caused by fusion hardening, and the joined faces of the films are fused together. The sealed part is obtained by using the polyvinyl alcohol films, by applying polyvinyl alcohol plasticizer to the joined insides of the part to be sealed, by sealing the part under heat while preventing the presence of the plasticizer on the outsides of the films, thereby fusing the joined insides without imparting thermal history due to the fusion hardening to the outsides of the heat-sealed part.

Title: Silicon carbide sintered compact
Inventor: YUZAWA YOSHIHIKO
IPC: C04B35/565
Filed: 1988-04-01
Abstract: PURPOSE:To contrive improvement in corrosion resistance and sliding properties, by specifying the amounts of added B, C and Al in a sintered SiC compact prepared by adding the B, C and Al thereto. CONSTITUTION:The above-mentioned sintered compact consists of 0.05-0.14wt.% B, 0.01-0.04wt.% Al, 0.5-6.0wt.% C and <=0.15wt.% total amount of B and Al. This sintered SiC compact has high sintering density and mechanical strength with excellent corrosion resistance and sliding properties. In the afore- mentioned composition, alpha-, beta-SiC or a mixture thereof can be used as the SiC. Although Al enhances toughness, effects thereof are not produced if the amount thereof is <0.01wt.%. If the amount exceeds 0.04wt.%, heat resistance, such as high-temperature strength, and corrosion resistance are deteriorated. B enhances sintering properties; however, >=0.05wt.% B is required to impart denseness of the sintered compact due to reduced amount of Al. If the amount exceeds 0.14wt.%, corrosion resistance is deteriorated. The total amount of B and Al is <=0.15wt.% for ensuring corrosion and heat resistance. If the amount of C is <0.5wt.%, a good sintered compact is not obtained. If the amount exceeds 6.0wt.%, sintering properties are deteriorated.

Title: Method for treating excavation surplus soil
Inventor: HORIKAWA TAKESHI
IPC: C02F11/14
Filed: 1994-04-20
Abstract: PURPOSE:To restore excavation surplus soil to the nature in a short time by adding an aluminum salt to the soil containing additives comprising an anionic water-soluble polysaccaride and/or a water absorbent resin. CONSTITUTION:In a soil pressure type shield construction process, excavated earth and sand, after being mixed with an anionic water-soluble polysaccaride and/or a water absorbent resin, is discharged as excavation surplus soil through an earth and sand transportation pipe. The soil containing additives is mixed with an aluminum salt, especially potassium alum, so that the anionic water-soluble polysaccaride, e.g. carboxymethyl cellulose sodium salt (CMC), is made water-insoluble to be fixed in the soil. Aluminum acetate, etc., can be used in place of potassium alum; however, potassium alum is the most preferable in view of safety. The amount of the alum to be added is 20-100wt.% to the total of CMC and the water absorbent resin contained in the soil.

Title: Manual or electromotive toothbrush
Inventor: HANSU DEIETAA MIERAU
IPC: A46B15/00
Filed: 1985-04-17
Abstract: An electrically operated toothbrush comprises a housing with an electromotor inside the housing. The motor includes a rotatable shaft, means converting the rotary movement of the rotary shaft to an oscillatory movement of a brush support shaft which extends through the housing, and a toothbrush is attached to the free end of the support shaft outside of the housing. Sensing structure generates an impulse representative of the pressure exerted on the toothbrush during toothbrushing. A microprocessor or electronic device receives the impulses from the sensing structure during toothbrushing and compares those impulses with stored information representative of a predetermined optimum pressure range for toothbrushing. A signal transmittor releases a signal perceptible by the user of the toothbrush when the pressure on the toothbrush exceeds the predetermined optimum pressure range.

Abstract: PURPOSE:To correct the imaging magnifications differing in the scanning direction of a rotary reflecting mirror and in the direction orthogonal to this and project the images so as to be formed at the same imaging magnification in both direction by providing at least one anamorphotic optical system. CONSTITUTION:Light emitting from the first plane 6 positioned on the focal plane of the first imaging optical system 7 of rotation symmetry passes through the first imaging optical system 7 to become parallel luminous fluxes which are then deflected by a rotary reflecting mirror 8 and are proejcted onto the second plane 11 disposed to the imaging position of the second imaging optical system 10 of the rotation symmetry. Since an anamorphotic variable power lens group 9 is disposed on the optical paths between the rotary reflecting mirror 8 and the second imaging lens group 10, the change rates vary in the scanning direction and in the direction orthogonal to this, from which the distortions of the image formed on the second plane 11 may be corrected.

Abstract: PURPOSE:To obtain an optical card of high reliability having mechanical strength and made possible in optically stable recording and reproduction by arranging two polycarbonate sheets so that the orientations of the molecular chains of both sheets cross each other at an angle of a specific range and providing a guide groove and/or a preformat data pattern on the side of an optical recording layer. CONSTITUTION:This optical card is formed by laminating a polycarbonate laminated sheet 1A consisting of two polycarbonate sheets 1Aa', 1Ab' having double refraction due to the orientation of a molecular chain and an acrylic film 1B having a tracking guide groove for recording and reproduction and/or a preformat data pattern 2 preliminarily recording header data such as an address formed thereto, the optical recording layer 3 on the acrylic film 1B and the backing substrate 5 provided to said layer 3 through an adhesive 4. Therefore, by laminating the sheets whose orientations cross each other at a right angle under pressure and heating, double refraction is reduced. Further, in such a state that the strength characteristics of polycarbonate are kept, by forming the acrylic film on the polycarbonate sheet, the releasability with a stamper at the time of the formation of the guide groove and/or the preformat data pattern is enhanced and the moldability of the guide groove and/or the pattern is made stable.
