  • Patent number: 8794207
    Abstract: A method for processing a cylinder block is disclosed, wherein a protrusion protruding toward a crankcase is provided at a crankcase-side edge of a cylinder bore and a sprayed coating is formed on an inner surface of the cylinder bore and an inner surface of the protrusion continuous with the inner surface of the cylinder bore. After forming the sprayed coating, at least part of the protrusion is removed together with the sprayed coating formed on the inner surface of the protrusion. Accordingly, even in the case of removing the edge portion of the cylinder bore on the crankcase side, a sufficient margin to be removed can be ensured while a reduction in size of the cylinder block is achieved.
    Type: Grant

  • Patent number: 5070914
    Abstract: A triaxial textile fabric for use as a reinforcing textile fabric for a composite material wherein the modulus of elasticity is made isotropic and which can be readily deformed into a three-dimensional configuration without causing special changes in orientation angles and a process by which such a textile fabric can be easily produced. The fabric comprises a large number of oblique yarns extending in a radial direction from the center of the textile fabric, and a circumferential yarn woven spirally in a circumferential direction between the oblique yarns. Each adjacent ones of the oblique yarns are interlaced with each other and the circumferential yarn is woven between the thus interlaced oblique yarns such that such interlacing may appear between each adjacent coils of the spirally woven circumferential yarn. Such an interlacing step takes place after insertion of the circumferential yarn and before an upward and downward movement of the alternate oblique yarns.

  • Patent number: 4938270
    Abstract: A spherical cloth weaving machine in which radially stretched warp yarn and circumferentially running weft yarns are woven into a desired spherical shape, the machine being constructed with a mechanism for moving the warp yarns alternately by shuttle chucks which hold required numbers of the warp yarns at their outer peripheral part. A mechanism is provided for hooking the circumferential weft yarn and beating the same toward the center of the warp yarns for compact weaving. A weft yarn rotating mechanism causes the weft yarn to pass through the warp yarns which are being moved by the warp yarn moving mechanism. A mechanism is provided for maintaining the woven cloth in a spherical shape.
