  • Patent number: 11655353
    Abstract: A sheet molding compound (SMC) is provided with superior conductivity properties based on the use of graphitics. A process for exfoliation of GnP and turbostratic carbon is also provided. By exfoliating the graphitics, a reduced amount of material can confer comparable properties relative to native GnPs or turbostratic carbon thereby reducing the amount of material usage, but also reducing negative effects to the base resin formulation through inclusion of these additives. Particular utility is found in thermoset resin molding to produce articles that are amenable to electrostatic coating and other surface treatments that rely on surface conductivity and especially in the realm of vehicle body parts.

    Abstract: A unitary graphene-based continuous graphitic fiber comprising at least 90% by weight of graphene planes that are chemically bonded with one another having an inter-planar spacing from 0.3354 to 0.4 nm and an oxygen content of 0.01 to 5% by weight, wherein the graphene planes are parallel to one another and parallel to a fiber axis direction and the graphitic fiber contains no core-shell structure, have no helically arranged graphene domains, and have a porosity level less than 5% by volume. This fiber can be produced by a continuous filament of graphene oxide gel having living graphene oxide molecules or functionalized graphene chains dissolved in a fluid medium. The filament is deposited onto a supporting substrate under a molecule-aligning stress condition along the filament axis direction and then subjected to drying and heating treatments.

  • Patent number: 10818518
    Abstract: A plurality of surface mounting components are arranged on a component mounting surface of a transfer substrate. A resin layer is formed on the transfer substrate and the plurality of surface mounting components are buried in the resin layer. The resin layer is peeled off the transfer substrate, with the plurality of surface mounting components buried in the resin layer, to expose a surface resin layer. An intermediate auxiliary layer is provided on the exposed surface of the resin layer. The intermediate auxiliary layer has openings to expose respective mounting terminals of the surface mounting component. Metal materials are arranged in the openings. A wiring sheet which includes a thermoplastic resin sheet with an electrode pattern and a plurality of unmetallized via patterns is joined to the intermediate auxiliary layer so that each of the via patterns aligns with a respective one of the openings in the intermediate auxiliary layer.

  • Patent number: 10772605
    Abstract: The present invention provides an ultrasonic endoscope in which wiring can be reliably fixed to a wire housing space of an ultrasonic-oscillator housing part, and a method of manufacturing the ultrasonic endoscope. According to the present invention, a wire housing space is encapsulated from the outside by sealing a gap formed between an ultrasonic oscillator and an ultrasonic-oscillator housing part with sealing members. With this configuration, the wire housing space can be sufficiently filled with filling agent for fixing wires in the wire housing space. This achieves an ultrasonic endoscope in which the wires can be reliably fixed to the wire housing space of the ultrasonic-oscillator housing part.
