  • Patent number: 10672947
    Abstract: A metal layer is formed by vapor deposition or sputtering on an AlN substrate. Since there are irregularities on the surface of the substrate, irregularities are also formed on the surface of the metal layer. Subsequently, irregularities on the surface of the metal layer are removed and flattened in a mirror state by grinding the surface of the metal layer. Then, a dielectric layer is formed on the metal layer by alternately forming a SiO2 film and a TiO2 film through CVD. Next, an electrode layer is formed in a predetermined pattern by vapor deposition and lift-off on the dielectric layer. Since the surface of the metal layer is flattened in a mirror state, reflectance is high on that surface. As a result, the emission efficiency of the light-emitting device can be improved.

  • Patent number: 10661746
    Abstract: An airbag device for a passenger seat is disclosed. The airbag includes a main section whose rear plane forms a front-collision arresting plane, and a sub section which is disposed on a side of the main section and includes a protruding region protruding farther rearward than the main section. The side plane of the protruding region forms an oblique-collision arresting plane. Between the front-collision- and oblique-collision arresting planes is an arresting recess denting forward. The airbag further internally includes a front-rear tether jointed to the front-collision arresting plane, and a recess-pulling tether jointed to the bottom of the arresting recess. The front-rear tether and recess-pulling tethers share a mounting base by which the tethers are mounted on an airbag case, and bifurcate from the mounting base. The front-rear tether extends from a rear edge of the mounting base, and the recess-pulling tether extends from an edge of the mounting base adjoining the front-rear tether.
