  • Publication number: 20200040175
    Abstract: [Object] To provide a ring-shaped sealing member having both the sealing property and slidability. [Solving Means] A sealing member is formed in a ring shape and has a sliding surface. The sealing member includes: 100 parts by weight of fluorine rubber; and 0.5 to 50 (inclusive) parts by weight of a particulate resin. The particulate resin includes a compatible portion and a lubrication portion, the compatible portion having compatibility with the fluorine rubber, the lubrication portion having lubricity with respect to the fluorine rubber. A Shore A hardness measured using the sliding surface as a pressing surface is not less than 80. In this sealing member, since rubber elasticity is achieved by the fluorine rubber, a favorable sealing property can be realized. Further, it is possible to impart high slidability to the sealing member by the action of the lubrication portion of the particulate resin. Therefore, this sealing member has both the sealing property and slidability.

  • Patent number: 10546700
    Abstract: A laminate-type power storage element has a flat body and an interior layered flat plate-shaped electrode body. A positive electrode terminal plate is mounted to a positive electrode of the electrode body and is guided outside from a predetermined margin of the body. A negative electrode terminal plate is mounted to a negative electrode of the electrode body and guided in the same direction. A film member spans across both electrode terminal plates. The film member is made by layering an insulating heat-resistant film and an adhesive to thermocompression bond the heat-resistant film to a matter to be adhered to. The film member is thermocompression bonded to the electrode terminal plate at a region facing principal surfaces of the positive and the negative plates, and is thermocompression bondable to the matter to be adhered to in a region that does not face the respective principal surfaces.

  • Patent number: 10387995
    Abstract: A semiconductor device 1 includes an image input unit 11 and an image output unit 12. The image input unit 11 receives first image data from a camera 91 and outputs second image data to a memory unit 93 through a shared bus 130. The image output unit 12 receives the second image data stored in the memory unit 93 through the shared bus 130 and outputs third image data to a monitor 92. The third image data is generated by performing an affine-conversion on the first image data. Magnification processing in the affine-conversion is not performed in the image input unit 11. In this way, it is possible to provide an excellent semiconductor device suitable for image processing or the like.

  • Patent number: 10362182
    Abstract: An image forming apparatus transmits a sheet feeding request to the sheet feeding device, obtains a sheet through a receiving device and performs image formation on the sheet. The receiving device comprises an inlet sensor for detecting a sheet fed from the sheet feeding device. The image forming apparatus transmits the sheet feeding request to the sheet feeding device again in a case where the inlet sensor does not detect a sheet within a predetermined time after the sheet feeding device starts to feed a sheet and no signal indicating an abnormality with regard to a sheet is received from the sheet feeding device. If the number of times the sheet feeding request is transmitted exceeds a predetermined number of times, the image forming apparatus stops operation.
