    摘要: Expandable styrene resin beads are described, which, when expanded to a bulk density of 20 g/l, give pre-expanded beads in which the number of cells present along those surface parts of radii which range from the bead surface to a depth of 0.2 mm from the surface is from 3 to 20 per mm and the number of cells present along those inner parts of the radii which range from a depth of 1 mm from the bead surface to the bead center is 10 or larger per mm, the number of cells present along said surface parts being smaller than the number of cells present along said inner parts.

    摘要: A ball for ball game comprises a rubber hollow spherical bladder, a valve holder fixed to the tube for charging air into the tube, a valve member attached to the valve holder; a fabric layer covering the bladder surface and a leather layer. The fabric layer is composed of a plurality of equilateral quadrilateral pieces sewn together to form a sphere. The equilateral quadrilateral pieces each include two sheets of approximately trapezodial fabric pieces that are sewed together symmetrically at a central seam line. The equilateral quadrilaterla pieces are sewed together such that central seam lines of adjacent equilateral quadrilateral pieces fall at right angles to ech other. The fabric layer gives sphericity, dimensional stability and durability to the ball. The leather layer is adhered to the fabric layer directly or through a rubber based thin intermediate layer. On a circumferential line in the fabric layer which includes one seam line, at least one other seam line exists at a prescribed interval to equally divide the un-sewn portions. All segments on the spherical surface of the fabric layer, which are divided by a plurality of circumferential lines including all of the seam lines, have the same shape.

    摘要: A color ink ribbon in which one half of the width of the ribbon is utilized for the left-to-right (first) printing direction and the other half of the width is utilized for the right-to-left (second) printing direction, and in which the sequence of ink layers composed of at least three colors is the same for both printing directions, whereby the ribbon can be used for printing in both the forward and reverse directions without wasteful non-utilization of areas in either half of the ribbon.

    摘要: A toothed belt having a fabric adhered to the toothed portion of the belt formed of synthetic resin yarns having an ultimate viscosity of greater than approximately 1.30. In the illustrated embodiment, the yarns extending in the longitudinal direction of the belt are fully processed yarns. The cloth is preferably a woven cloth wherein one or the other of the weft and warp are wooly processed. The use of the disclosed cloth provides a substantial improvement in resistance of the belt to cracking and shearing of the teeth in use.
