  • Patent number: 11015709
    Abstract: A gasket 100 is configured to seal a gap between an installation member 200 and a fixation member 300 which are fixed to each other. The gasket 100 has an annular gasket main body 11 configured to be fitted into an annular groove 210 provided in the installation member 200 and configured to be in close contact with a bottom surface 210a of the annular groove 210 and with an end surface 310 of the fixation member 300, and an auxiliary seal portion 12 extending from the gasket main body 11 toward an opposite region, which is opposite to a sealed region. The auxiliary seal portion 12 is configured to be in close contact with an end surface 220 of the installation member 200 on the opposite region side of the annular groove 210 and with the end surface 310 of the fixation member 300.

  • Patent number: 10520088
    Abstract: The present invention addresses the problem of providing: a metal gasket capable of limiting the loss of axial bolt fastening force even if a peripheral creased section is formed as an anti-saline intrusion measure; and a metal gasket, which has relatively small curved sections with a radius of curvature of not more than 20 mm on the outer edge and which is capable of limiting loss of axial bolt fastening force even when a peripheral creased section is formed over the entire perimeter of the metal gasket as an anti-saline intrusion measure. Said problem is solved by a metal gasket, which is disposed between the abutting surfaces of two members and has, on a metal base plate: bolt holes into which bolts are inserted; a bead that is to the inside of the bolt holes and is for sealing between the abutting surfaces; and a peripheral creased section configured by bending the perimeter of the metal base plate in one direction so that no gap in which saline can accumulate is formed between the abutting surfaces.

  • Publication number: 20180335142
    Abstract: A metal gasket includes: a straight section provided with a bolt hole; a bead section raised from an inner peripheral edge of the straight section toward one side of the direction of the thickness of the gasket; and a bent section bent from an outer peripheral edge of the straight section toward the other side of the direction of the thickness of the gasket. When metal gasket is compressively sandwiched by a pair of housings, bead section elastically deforms to decrease height, and straight section elastically deforms, whereby the inner peripheral edge of the straight section contacts one of the housings, the outer peripheral edge of the straight section contacts the other housing, and the bent section contacts the one of the housings. A gasket installation determination projection is part of the periphery and provided on the outer peripheral edge of the bent section or of the straight section.

  • Patent number: 9332152
    Abstract: An image processing apparatus includes an input unit that receives data of an image, an encoding unit that encodes multiple data blocks respectively representing multiple partial images forming the image to generate multiple pieces of encoded information, a determining unit that determines a reading sequence of the data blocks with respect to each of multiple image rotation angles, and a memory that stores, in an associated form, multiple pieces of sequence information representing the determined sequences with respect to the image rotation angles, and the multiple pieces of generated encoded information.
