  • Publication number: 20170074479
    Abstract: In a vehicle lamp of the present disclosure, a lamp body is made of an acrylonitrile styrene acrylate (ASA) resin, which has a glass transition temperature lower than that of a poly(methyl methacrylate) PMMA resin constituting a light transmissive cover. That is, with respect to the glass transition temperature Tg1 of the PMMA resin constituting the light transmissive cover, the glass transition temperature of the ASA resin constituting the lamp body is set to Tg1>Tg2. Thus, it is possible to generate not a tensile residual stress but a compressive residual stress in a welding portion between the lamp body and the light transmissive cover, thereby enhancing the solvent resistance of the light transmissive cover. And, thus, an annealing process after the welding is unnecessary, or simply performed.

  • Publication number: 20170074514
    Abstract: A fabricated article includes a substrate and one or more turbulators formed on the substrate. Each of the one or more turbulators includes at least one root portion providing a concave transition between the substrate and the turbulator. In some embodiments, the fabricated article is formed by a turbulator fabrication process. The turbulator fabrication process includes concurrently directing the first fusion energy toward a first side of the turbulator material extending from the substrate and the second fusion energy toward a second side of the turbulator material opposite the first side and extending from the substrate. The directing of the first fusion energy and the second fusion energy shapes the first side of the turbulator material to have a first contour and the second side of the turbulator material to have a second contour, thereby forming the one or more turbulators on the substrate.
