  • Patent number: 11346799
    Abstract: An ultra-miniaturized, low-cost, and maintenance-free chemical sensor is capable of continuously monitoring the concentration of specific volatile organic compound (VOC) vapors released from crop plants and green plants under distress from pests or disease. The sensor is based on micromechanical structures and relies on the mechanical actuation induced by the chemical interaction between the VOCs and materials in the microstructure to passively generate a wake-up bit when the concentration of VOCs exceeds a predetermined value. The sensor does not consume power while in standby mode (i.e., when certain VOC vapors are not present), and wirelessly communicates the location of impending outbreaks upon detection of a predetermined concentration of certain VOC vapors.

  • Patent number: 8927174
    Abstract: A sealing structure of a fuel cell has a first gasket made of an elastomer and provided integrally on a separator, and a second gasket made of an elastomer and provided integrally on other separator. A membrane-electrode assembly is sandwiched or pinched by the first and second gaskets. The first gasket has a main lip in which a top portion brought into close contact with the membrane-electrode assembly is formed flat. The second gasket has a flat seal portion and a sub lip protruding from this flat seal portion at a position opposing the main lip. The flat seal portion and the sub lip are brought into close contact with the membrane-electrode assembly. The width of the top portion of the main lip is narrower than the width of the flat seal portion, and larger than the width of the sub lip.

  • Patent number: 8883366
    Abstract: A device includes a ceramic thin plate member including a fired ceramic sheet; and a metal thin plate member having an outer shape larger than that of the ceramic thin plate member. An outer circumferential portion of the ceramic thin plate member is joined to the metal thin plate member. The ceramic thin plate member has through holes and a plurality of crease portions. Each crease portion has a ridge portion whose crest continuously extends from a joint portion between the ceramic thin plate member and the metal thin plate member toward an outer circumferential portion of the metal thin plate member. Since thermal stress due to a difference in thermal expansion between the metal thin plate member and the ceramic thin plate member can be relaxed through expansion of the crease portions, the ceramic thin plate member does not deform.
