Title: Low migratable vinyl chloride resin sheet
Inventor: SUZUKI TAKURO
IPC: C08J5/18
Filed: 1992-06-07
Abstract: PURPOSE:To provide a so-called low migratable vinyl chloride resin sheet, based on vinyl chloride resin (especially, paste) as a raw material, such that migration of plasticizer contained in the sheet is prevented and extraction of the plasticizer by solvent is also prevented. CONSTITUTION:A polyester plasticizer of high molecular weight and an ester carboxylate plasticizer of mononuclear aromatic carboxylic acid having 3 to 6 carboxylate groups and a bulky chemical structure, are jointly used at a weight ratio of 1:9 to 9:1. Consequently, an increase of the viscosity of vinyl chloride paste which occurs, when the polyester plasticizer of high molecular weight is used alone, and the inferior gelation characteristic of vinyl chloride paste which is when the bulky ester carboxylate plasticizer of mononuclear aromatic carboxylic acid is used alone, are eliminated by synergic action of the joint use of both plasticizers. Thus, it is possible to obtain the low migratable vinyl chloride resin sheet which can be easily manufactured and is satisfactory as a finished product.

Title: Joint ring
Inventor: KAMITE MASAYUKI
IPC: E04F11/18
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To deal with linear expansion of a balustrade and maintain the appearance favorable by putting a joint ring formed out of soft material softer than the long members between the end parts of composite balustrades combining together long members of different coefficient of linear expansion. SOLUTION: The surface of a coping receiving core material 40 is covered with a coping material 30. Next a fitting member 60 is fitted to the opposite side to a building frame of a balustrade bracket 70. Next a slide groove 41 is inserted to the left side of the fitting member 60. Next a ring opening part 13 is fitted to the fitting member 60 so as to push a joint ring 10 thereto. The projecting part 12 is inserted into the insert groove 42 of the coping receiving core material 40. Similarly the slide groove 41 is inserted to the right side of the fitting member 60, the projecting part 12 is inserted into the insert groove 42, and the fitting member 60 is slid inside the slide groove 41 so as to fix to a building frame 90.  Because the coefficient of linear expansion of the coping material 30 or the core material 40 is different from that of the ring, the deformed quantity of the each member is absorbed by the ring 10. Hereby, the appearance can be maintained favorable.

Filed: 1985-08-06
Abstract: PURPOSE:To reduce the surface pressure of bands to prevent their life from shortening by dividing the laminated bands of blocks into the first and second band groups, and bringing the supporting planes of block bodies and those of supporting members into contact with the first and second band groups respectively. CONSTITUTION:V-belt blocks 3 are composed of many blocks laminated in the longitudinal direction of band groups 2, 2' to constitute a transmission V-belt.

The inner band group 2 and the band group 2' come into contact with supporting planes 25, 27 respectively, and those planes curve slightly outwards and convexly in both width and thickness directions. Each of the band groups 2, 2' is supported by the blocks 3, and surface pressure per band in contact with the block decreases as the number of bands in contact with the block increases to reduce the wear and elongation of the most inner bands 2a, 2a'.
