Marker, method for manufacturing same, and optical component

A transparent resin is injection molded to create a marker (10) as an integrally molded article (lenticular lens portion (11)) including convex surfaces (112) and recesses (113) formed on the rear side of the convex surfaces. The recesses (113) are filled with coating films (115) formed by applying and curing a fluid coating material. Each recess (113) is arranged corresponding to a convex surface (112) so that the coating films (115) can be observed as optically distinguishable from the side of the convex surfaces (112).

10557269 · 2020-02-11 · ·

A method for producing an injection molded and anti-skid mat providing a lower mold half and an enclosing upper mold half, the mold halves defining therebetween an interior cavity which is a negative of the mat to be produced. A cavity defining surface is configured in the bottom mold half with locations for preplacement of a plurality of underside adhering portions. A flowable plasticized/rubberized material is communicated through a channel in at least one of the mold halves in order to fill the interior cavity, the material setting and cooling prior to removing the upper mold half and the formed mat.

IRIDESCENT BADGES FOR VEHICLES

An iridescent vehicle badge (and methods for making it) that includes a translucent, polymeric badge having a non-planar shape and comprising an interior and an exterior surface. Further, at least one of the surfaces of the badge comprises a plurality of diffraction gratings that are integral with the badge, each having a thickness from 250 nm to 1000 nm and a varying period from 50 nm to 5 microns. In some cases, the thickness can range from 500 nm to 750 nm. The period, in some cases, can vary within a set of discrete values in one or more portions of the at least one of the surfaces of the badge, e.g., from 150 nm to 400 nm.

Anti-migration micropatterned stent coating

An endoprosthesis has an expanded state and a contracted state, the endoprosthesis includes a stent having an inner surface defining a lumen, having an outer surface, and defining a plurality of apertures through the outer surface, wherein the apertures are arranged in a micropattern; and a coating (e.g., polymeric coating) attached to the outer surface of the stent. The coating includes a base and a tissue engagement portion including a second surface facing outwardly from the stent, the tissue engagement portion including a structure that defines a plurality of holes extending inwardly from the second surface toward the base. The holes are arranged in a micropattern. When the endoprosthesis is expanded to the expanded state in a lumen defined by a vessel wall, the structure applies a force that may reduce stent migration by creating an interlock between the vessel wall and the endoprosthesis.

RESIN PRODUCT, METHOD OF MAKING RESIN PRODUCT, INTERCHANGEABLE LENS, AND OPTICAL DEVICE

A resin product including an antireflection surface includes a plurality of first concave portions, a plurality of second concave portions, and a component surface. The first concave portions have opening widths equal to or larger than 1 m and equal to or smaller than 300 m. The second concave portions are formed on each of the plurality of first concave portions and have opening widths equal to or larger than 10 nm and equal to or smaller than 1 m. The component surface is configured to surround each of the plurality of first concave portions.

Thermal interface adhesion for transfer molded electronic components

An electronic component to be encapsulated is introduced into a mold cavity. The mold cavity includes at least first and second halves, and at least one of the halves is formed with a negative of a thermal-interface-material engaging pattern thereon. An encapsulating material, which encapsulates the electronic component and engages the negative of the thermal-interface-material engaging pattern, is introduced into the mold cavity. The encapsulating material is allowed to solidify such that a thermal-interface-material engaging surface of the encapsulant solidifies with the thermal-interface-material engaging pattern thereon. During subsequent assembly, the thermal-interface-material engaging pattern engages thermal interface material to resist lateral motion of the thermal interface material.
