  • Patent number: 10807587
    Abstract: A hybrid vehicle includes: an engine; a catalyst; a motor generator; and a drive control unit. The catalyst is provided in an exhaust path of the engine. The motor generator is coupled to the engine and capable of regenerating electric power.

  • Patent number: 9291548
    Abstract: The invention makes it possible to measure binding of a biochemical substance with a high throughput and with high sensitivity using a small cell capable of being filled with a small amount of chemical solution. A space between a first substrate and a second substrate such that probes are immobilized on their mutually facing planes is used as a cell that houses a specimen solution. Light is irradiated from a first substrate side, and reflected light is subjected to spectroscopy. Binding of the target with the probe is detected by a wavelength shift in the refection spectrum.

  • Publication number: 20140211373
    Abstract: The purpose of the present invention is to provide composite particulates and a method for manufacturing the composite particulates, the particulates including an organic substance and a metal having exceptional adhesiveness to a substrate, allowing easier control over metallic particle dispersion, facilitating control over electrical conductivity, and exhibiting high electroconductivity. The metallic particulates are characterized in that they have a thiol compound coordinated on the surfaces thereof, they are adsorbed onto a substrate with a silane compound interposed therebetween, and the thiol compound on the surfaces is subjected to oxidative polymerization, thereby yielding a structure in which an electroconductive polymer is coordinate-bonded to the surface of the metallic particulates.
