  • Patent number: 10737654
    Abstract: A case for housing an inflator includes a protruding region for storing a connector of a wire harness which is connected to an inflator body. A body of the wire harness extends from the connector in a direction orthogonal to an axial direction of the inflator body. The protruding region protrudes from a circumferential wall of the case partially. The protruding region includes a stopper wall that is opposed to the connector as stored in the case in the axial direction of the inflator, and a pair of limiting walls that are engageable with the wire harness by the leading ends and thus limit an angle range with respect to the inflator body within which the wire harness is rotatable. The limiting walls each extend from the stopper wall and are disposed on both sides of the connector in the direction orthogonal to the axial direction of the inflator.

  • Patent number: 10710541
    Abstract: An airbag includes a body, an insert opening and a flap member which covers the insert opening from inside of the airbag. A retainer is inside the airbag, and an inflator is inserted into a holding section of the retainer via the insert opening such that the root end protrudes from the insert opening. The flap member entirely covers the insert opening of the airbag body as unfolded and is joined to the airbag body, with a continuous seam, by the circumferential edge except the leading edge disposed towards the leading end of the inflator. The flap member thus covers the holding section. The retainer includes an open region which exposes an outer periphery of the inflator towards the flap member, and the leading edge of the flap member is positioned to be pressed against the outer periphery of the inflator via the open region at airbag deployment.

  • Patent number: 10696264
    Abstract: Provided is an airbag which can be easily manufactured though it is provided with a tether inside, and has a reduced fear of gas leakage from a joint region. The airbag includes a joint region of outer circumferential edges of a pair of walls. The joint region includes, between the outer circumferential edges of the pair of walls, a sealing member which has elasticity, and has adhesiveness in an unsolidified state. The joint region is formed by such a sewing that runs a sewing thread through an application area of the sealing member. A tether connects the pair of walls. The joint region includes a region in which the sealing member has a solidified, thus non-adhesive surface, and is pressed against at least one of the walls by the non-adhesive surface, and penetrated by the sewing thread in that state.

  • Patent number: 10693224
    Abstract: A radio-wave transmitting cover is configured to be arranged in the path of the radio wave of a radio-wave radar device. The thickness of the cover is set to a reference thickness at a reference position where the incident angle of the radio wave from the radio-wave radar device is 0°. The reference thickness is set to a value obtained by multiplying half of the wavelength of the radio wave by an integer. In the area around the reference position, the thickness of the cover is gradually changed such that the greater the distance from the reference position, the greater becomes the difference by which the thickness of the cover is larger than the reference thickness.

  • Patent number: 10693032
    Abstract: The seed substrate comprises a base substrate and a base layer comprising a Group III nitride semiconductor formed on the base substrate, which has a high dislocation density region and a low dislocation density region. The planar pattern of the high dislocation density region is a honeycomb pattern. A hollow exists between the base substrate and the low dislocation density region. The object layer is grown through a flux method using the seed substrate. The high dislocation density region is melted back at an initial stage of crystal growth, and thereafter, the object layer is grown on the top surface of the low dislocation density region. A cavity remains between the high dislocation density region and the object layer. The presence of the cavity and the hollow makes easy to peel the object layer from the seed substrate.

  • 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.
