  • Patent number: 12122863
    Abstract: The invention provides novel pellets having high fluidity in a hopper of an extruder and capable of forming a coating layer having good wire diameter stability and capacitance stability even when used for rapid molding of electric wire coating. The pellets contain a fluororesin. Each of the pellets, placed on a horizontal surface, has a substantially circular outline or a substantially elliptic outline and has a major axis D1 of 3.1 mm or shorter and a minor axis D2 of 3.1 mm or shorter when observed in the direction normal to the horizontal surface. Each pellet satisfies the following formula (1): (D1+D2)/2L=1.8 to 2.6, wherein D1 represents the major axis, D2 represents the minor axis, and L represents the height from the horizontal surface to the highest point of the pellet.

  • Patent number: 9604012
    Abstract: A barrel with a cap, a pre-filled syringe, and a cap with a connector that accommodate connection-receiving bodies of the Luer lock type and of the slip-in type, are provided. Some versions include: a connector (3) detachably coupled to a cap (2) so as to be separated from the barrel (1) together with the cap (2) when the connector (3) is located at an initial position where the connector (3) is attached to a barrel (1) via the cap (2); and a connector-side engaging part (33) that engages a barrel-side engaging part (13) of the barrel (1) when the connector (3) is located at an attached position that is closer to a proximal end in an axial direction of the barrel (1) than the initial position, allowing the connector (3) to remain attached to the barrel (1) by being detached from the cap (2) separated from a nozzle (11).

    Abstract: The present invention provides a barrel with a cap, a pre-filled syringe, and a cap with a connector that are available for both connection-receiving bodies of the Luer lock type and connection-receiving bodies of the slip-in type. The present invention is characterized by including: a connector (3) that is detachably coupled to a cap (2) so as to be separated from the barrel (1) together with the cap (2) when the connector (3) is located at an initial position where the connector (3) is attached to a barrel (1) via the cap (2); and a connector-side engaging part 33 that engages a barrel-side engaging part (13) of the barrel (1) when the connector (3) is located at an attached position that is located closer to a proximal end in an axial direction of the barrel (1) than the initial position is, thereby allowing the connector (3) to remain attached to the barrel (1) by being detached from the cap (2) separated from a nozzle (11).

  • Patent number: 6452653
    Abstract: A reflector comprises a substrate provided with a plurality of projecting and depressed structures which are groups of columnar portions each serving as a basic unit and composed of a plurality of minute columnar portions, which are separate from each other or at least partially connected to each other, and with a light reflecting thin film provided over the projecting and depressed structures. This allows incident light to be scattered and reflected in a forward direction or the like, not in the regular reflection direction, and provides a reflector having a superior contrast property and a superior paper-white property, a fabrication method therefor, and a reflective display device comprising the reflector. The reflective display device has a liquid crystal layer provided between a pair of substrates. One of the pair of substrates is provided with projecting and depressed portions covered with a metal film and with a support portion for supporting the counter substrate, which are molded integrally.

  • Patent number: 6166834
    Abstract: A dichroic or trichromatic transparent display apparatus through which a background view is seen comprises a transparent substrate, a hologram formed on a rear face of the transparent substrate, a dispersion liquid crystal device disposed in front of a front face of the transparent substrate, a light source disposed for facing a side face of the transparent substrate and a transparent layer at least partially provided between the transparent substrate and the hologram. The refractive index of the transparent layer is smaller than that of the transparent substrate. A first light emitted from the light source and having a first wavelength is totally reflected by the boundary face between the transparent substrate and the transparent layer so that the first light moves to and is diffracted by a first region of the hologram where the transparent layer is not provided. A second light having a second wavelength is diffracted by a second region of the hologram where the transparent layer is provided.

  • Patent number: 5396862
    Abstract: A compound semiconductor thin film is grown on a compound semiconductor surface, which is cleaned by irradiating the surface with gas containing at least hydrogen molecules and by efficiently removing contaminant on the surface at low temperature. A beam containing at least hydrogen molecules is irradiated from a plasma generating room attached to a MBE chamber, and cleans the surface of a compound semiconductor at low temperature. By an additional mechanism attached to the MBE chamber, a compound semiconductor thin film of high quality is grown on the cleaned surface of the compound semiconductor.
