  • Publication number: 20250115741
    Abstract: A conductive resin composition contains matrix resin, coke powder, carbon fiber, and a phosphorus-based flame retardant including (poly)phosphate. The volume mean particle diameter of the coke powder is not less than 1 ?m and not more than 500 ?m. The content of the coke powder in the conductive resin composition is not less than 5 mass % and not more than 17 mass %. The aspect ratio of the carbon fiber is not less than 3 and not more than 1700. The content of the carbon fiber in the conductive resin composition is not less than 0.5 mass % and not more than 5 mass %. The content of the phosphorus-based flame retardant in the conductive resin composition is not less than 10 mass %.

  • Patent number: 12215972
    Abstract: Provided is a sensor device in which the sensitivity of a strain sensor is hardly inhibited despite the fact that a glass material is used as a protective material, and in which the glass material hardly breaks. The sensor device of the present invention includes: an optical laminate including a glass film, an adhesive layer, a resin layer, and a pressure-sensitive adhesive layer in the stated order; and a strain-sensing unit, wherein the glass film has a thickness of from 20 ?m to 150 ?m. In one embodiment, the strain-sensing unit is arranged on a pressure-sensitive adhesive layer side of the optical laminate.

  • Patent number: 12203622
    Abstract: A light distribution controller controls a light distribution variable lamp including a plurality of pixels arranged in an array. The processor executes the software program to generate at least one image defining the light distribution of the light distribution variable lamp, and writes the image in the volatile memory. A monitoring microcontroller detects an abnormality of the processor. A hardware logic circuit (i) generates a light distribution image data to be output to the light distribution variable lamp on the basis of at least one image written in the volatile memory in a normal state of the processor, and (ii) generates a light distribution image data on the basis of the generated auxiliary image without depending on the processor in an abnormal state of the processor.

  • Patent number: 9012548
    Abstract: An object of the present invention is to provide a polypropylene resin composition that is blended in a polyolefin resin to improve its surface characteristics and impart sustained water repellency and yet is low in aggregates so as not to deteriorate the visual appearance, a polyolefin resin composition containing the polypropylene resin composition, and a molded article of the polyolefin resin composition. A composition that achieves the object is a polypropylene resin composition obtained by heating and kneading a material containing (A) a polypropylene resin, (B) a polypropylene wax, (C) a polyorganosiloxane containing at least one silicon-atom-bonded alkenyl group in each molecule, and (D) an organic peroxide.
