  • Patent number: 12329929
    Abstract: A filtration device includes: a housing that defines a liquid flow path; and a filtration sheet that separates the liquid flow path into a flow path upstream side and a flow path downstream side. The housing includes: a first housing member and a second housing member that sandwich the filtration sheet, and a joining member that joins the first housing member and the second housing member in a state in which the filtration sheet is sandwiched between the first housing member and the second housing member. A gap is located between the first housing member and the second housing at a position outward of an outer edge of the filtration sheet. The joining member seals the gap between the first housing member and the second housing member at the position outward of the outer edge of the filtration sheet.

  • Patent number: 11116958
    Abstract: A connector includes: a housing that includes a tubular body connecting unit to which a tubular body is connectable, a concave portion inside the housing, and a receiving portion; and a valve body configured such that, when the tubular body is connected to the tubular body connecting unit, the valve body is pressed by the tubular body against a biasing force, thereby sliding from a closed position to an opened position. The valve body includes an overriding portion configured such that, as the valve body slides from a closed position side toward an opened position side, the overriding portion is pressed against the receiving portion of the housing and rides over the receiving portion by elastic deformation.

  • Patent number: 8233549
    Abstract: A video receiving apparatus includes a receiving unit, a detecting unit, a determining unit, and a control unit. The receiving unit receives a video stream transmitted from a video distribution apparatus and to be reproduced by a video reproducing unit. The detecting unit detects an error occurrence position on the video stream in response to an error occurring during receiving of the video stream. The determining unit determines a reproduction start time based on the error occurrence position detected by the detecting unit and a position of a predetermined synchronization code in the video stream so that reproduction of the video stream is started before the error occurrence position. The control unit transmits a reproduction request including the determined reproduction start time to the video distribution apparatus.
