  • Patent number: 10682978
    Abstract: An airbag device for pedestrian protection to mount on a vicinity of the rear end of a vehicle hood. The airbag includes a transverse inflatable portion that covers a cowl of the vehicle generally entirely in the vehicle width direction when deployed, and an inlet port in a front end region of the transverse inflatable portion to couple with an inflator. The airbag is stored folded-up in a housing. The airbag is folded up through a front-rear contracting step that provides a front-rear contracted bag, i.e. the airbag which has gone through the front-rear contracting step, and a transversely contracting step which folds the front-rear contracted bag with a crease at a vicinity of an outer end in a left and right direction of the inlet port. A transversely-contracted fold portion formed in the transversely contracting step and the inlet port are arranged in a stratified fashion.

  • 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.
