IPC: B60B3/06
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the development of shrinkage cavity in a rim frange even if a rim is made to thin by forming a gap to the mating surface between an inside part and an outer cylinder and mutually bringing into tight contact with the inside part and the outer cylinder part of the rim flange part. SOLUTION: A fixed metallic mold 1 is fitted to a fixed plate. In a movable metallic mold 2, a hub fitting surface 3a, spoke back surface 4a and the inner surface of the rim 19 are formed. The movable metallic mold 2 is constituted with an upper insert 3, inner cylinder 4, outer cylinder 5 and backup mold 6 of a center cylindrical part. Then, in the case of setting the movable metallic mold 2 to the mold clamping condition, the gap is formed to the mating surface between the inside part (inner cylinder) 4 and the outside part (outer cylinder) 5 at the parts corresponding to the thin part in the rim, and the inside part (inner cylinder) 4 and the outside part (outer cylinder) 5 in the rim flange part 18 at thicker than the thickness of the rim 19 are mutually brought into close contact with each other.  By this method, the service life of the metallic mold can be extended without developing the fatigue breakage caused by thermal stress.

Filed: 1984-05-14
Abstract: PURPOSE:A dispersion stabilizer for preventing suspended beads from adhering to each other during the suspension polymerization of a vinyl monomer and for forming polymer beads of a sharp particle size distribution, comprising a copolymer containing N,N-dialkylacrylamide units and vinyl alcohol units. CONSTITUTION:A dispersion stabilizer for suspension polymerization, comprising a copolymer containing 0.1-20mol% N,N-dialkylacrylamide units of formula I (wherein R<1> and R<2> are each a 1-6C alkyl) and 99.9-80mol% vinyl alcohol units of formula II. When the above dispersion stabilizer is used in suspension- polymerizing a vinyl monomer (mixture) in an aqueous medium, substantially no adhesion of suspended beads occurs during polymerization because of its good suspension stabilizing effect, and polymer beads of a sharp particle size distribution can be obtained. Especially, in the suspension polymerization of a vinyl chloride monomer (mixture), it brings about advantages such as good moldability, high porosity, good plasticizer absorption and formation of substantially no fish eye during molding, in addition to the above merits.

Filed: 1986-04-26
Abstract: PURPOSE:To adapt a load cell to various shapes and dimensions by compensating the non-linearity of the output of a bridge circuit, by providing a strain detecting gauge to a region wherein the average value of strain quantities to the change in load changes linearity. CONSTITUTION:This wall parts 4...4 are formed to the end parts of the upper and lower beams 2, 3 of a strain generator 1 formed into a parallelogram shape. Two strain gauges 5...5, lead wires 6 for forming said gauges into a bridge circuit and terminals 7 for external connection are respectively formed to the upper surfaces of the thin wall parts 4, 4 of one beam 2 by a thin film process. The gauges 5...5 are arranged so that the centers C0 thereof are slightly shifted from the centers CC of the thin wall parts to the outside. By this constitution, strain changes in this region linearily with respect to the change in load and output sensitivity in this case is reduced because the gauge providing positions are slightly shifted from positions of the thin wall parts 4, 4 between center positions but the correspondence to this can be taken by raising the gain of an amplifier.
