  • Patent number: 9190812
    Abstract: A spark plug having a metallic shell extending along an axis (CL1) and a solid annular gasket. The metallic shell has an externally threaded portion and a seat portion, and the gasket has an inside diameter smaller than the thread diameter of the externally threaded portion and is provided between the externally threaded portion and the seat portion. The forward end surface of the gasket has an inclined portion which inclines rearward with respect to the direction of the axis (CL1) from the radially outer side toward the raidally inner side. The thickness of the gasket along the axis (CL1) is 2.0 mm or less; the distance along the axis (CL1) between the outermost circumferential edge and the innermost circumferential edge of inclined portion is 0.02 mm to 0.12 mm; and the Vickers hardness of the gasket is 60 Hv or more.
    Type: Grant

  • Patent number: 9046518
    Abstract: Provided is a strip-shaped detector that detects an analyte in a liquid sample. The detector includes a collecting member that directly collects a liquid sample from a living organism, a holding member that holds a labeling reagent binding specifically to the analyte in a state where the labeling reagent can move along with the movement of the liquid sample, a detecting member to which a detection reagent is immobilized which captures a complex of the analyte and the labeling reagent by binding specifically to the analyte, an absorbing member that can absorb the liquid sample, and a liquid-impermeable supporting member, wherein the respective members are arranged on the supporting member in the longitudinal direction of the detector so that the liquid sample moves through the inside of these members, and the collecting member includes a protruding portion sticking out of the supporting member at the upstream side in the movement direction of the liquid sample.
