  • Patent number: 11643708
    Abstract: The present invention relates to a nickel-based self-fluxing alloy, a glass manufacturing member, a mold, and a glass gob transporting member having an improved slipperiness against a glass gob. A nickel-based self-fluxing alloy used in a glass manufacturing member for transporting or molding glass with a viscosity of log ?=3 to 14.6, comprises: boron (B) in an amount of ranging from 0 percent to 1.5 percent by mass; hard particles; and silicon (Si). Preferably, the amount of boron (B) ranges from 0 percent to less than 1.0 percent by mass. Preferably, the hard particles contain at least one of a carbide, a nitrides, an oxide and a cermet. Preferably, the nickel-based self-fluxing alloy comprises at least one metal selected from Group 4, 5 and 6 elements in an amount of ranging from 0 percent to 30 percent by mass.
    Type: Grant

  • Patent number: 9717355
    Abstract: A cup-type container obtained by compression-forming a thermoplastic resin and including at least a flange portion, a body portion and a bottom portion, wherein a ratio (L/D) of the height of the container to the diameter of the opening is not less than 1.0, and if the direction of height of a test piece cut out from the body portion of the container is denoted by x and the circumferential direction thereof by y, a half-value width P at a half peak of a Miller index at a diffraction angle 2?=14.5° that represents the diffraction by the crystal plane (110), is in a range of 1.25 to 1.5 over the whole body portion in a peak intensity profile in the direction of height (x-direction) of a Debye's ring obtained by measuring the diffraction intensities by causing the X-rays to be incident on an x-y plane of the test piece at right angles thereto.

  • Patent number: 9573309
    Abstract: To efficiently feed a molten resin to the resin holders. An intermittently feeding device works to intermittently feed a transfer unit equipped with resin holders, and has a cam supported by a motor via a support. The cam is rotated by the motor. A cam follower of a moving block meshes with the screw of the cam, and the moving block moves along a support rail accompanying the turn of the cam. The motor rotates at a constant speed, and the transfer unit 3 is fed intermittently depending on the shapes of the cam and of the cam follower.
