  • Publication number: 20170263834
    Abstract: To prevent cracks on a sealing glass or a substrate in a LED package in which a light-emitting device is sealed with a sealing glass. The LED package comprises a substrate, a LED mounted on the substrate, and a sealing glass for sealing a LED formed on the substrate. A wiring pattern being connected to an electrode of the LED is formed on the surface of the substrate. A back electrode pattern is formed on the rear surface of the substrate. A columnar via is formed in the substrate. Thus, the wiring pattern on the surface of the substrate and the back electrode pattern on the rear surface of the substrate are electrically connected. A softening point of the substrate is set higher than softening point of the sealing glass.

  • Patent number: 9701853
    Abstract: Shown is an actinic ray-curable offset ink composition for foodstuff and pharmaceutical packaging which maintains superior curability without using a photosensitizer, which despite contributing to better curability (high productivity) tends to suffer from significant outward migration. The ink composition also suppresses outward migration of the monomers and photopolymerization initiators, and exhibits favorable adhesion to substrates.

  • Patent number: 9696658
    Abstract: A developer container, which includes an opening and is configured to store developer therein, includes a developer conveyance plate configured to convey the developer. The developer conveyance plate includes a vibration target unit configured to receive a vibration, and conveys the developer in a first direction in which the developer is conveyed toward an opening side, and in a second direction perpendicular to the first direction. The developer is conveyed by the vibration transmitted from the vibration target unit with use of a resultant force generated by adding a conveyance component in the first direction and a conveyance component in the second direction. A maximum acceleration a1 (max) in the first direction that is provided to the developer conveyance plate by the vibration transmitted from the vibration target unit is set to a lower acceleration than a maximum acceleration a2 (max) in an opposite direction from the first direction.

  • Patent number: 8826713
    Abstract: A method of manufacturing a stator coil for an electric rotating machine includes the steps of: (1) forming substantially planar electric wires each of which includes in-slot portions to be received in slots of a stator core and turn portions to be located outside the slots to connect adjacent pairs of the in-slot portions; (2) rolling each of the planar electric wires through plastic deformation into a spiral or circular-arc shape; and (3) assembling the rolled electric wires together to form the stator coil. Further, in the rolling step, each of the planar electric wires is rolled by deforming each of the turn portions of the electric wire while restricting movement of at least one of the in-slot portions of the electric wire which is located closer to a rolling start end of the electric wire than the turn portion is.

  • Patent number: 8691208
    Abstract: The present invention provides compositions and methods for use in enzyme replacement therapy. The inventors disclose a method of producing membrane bound enzymes in an active soluble form by eliminating the glycosylphosphatidylinositol (GPI) membrane anchor. In particular the inventors disclose a soluble active form of the membrane bound enzyme TNSALP which they produced by deleting the GPI anchor single peptide sequence. They have further shown that this composition is useful for treatment of hypophosphatasia. The inventors also disclose oligo acid amino acid variants thereof which specifically target bone tissue.
