  • 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. The drive control unit is configured to increase torque output from the engine and cause the motor generator to regenerate the electric power by using the torque output from the engine in the case where the hybrid vehicle is in a deceleration state and a temperature of the catalyst is lower than a specified catalyst activation temperature.

  • Patent number: 9926865
    Abstract: An evaporated fuel processing apparatus includes: a fuel tank that stores fuel supplied to an engine; a purge pipe that communicates an upper space in the fuel tank with an inlet system of the engine; an electromagnetic valve that is mounted on the purge pipe and that opens and closes the purge pipe; an air-fuel ratio detecting module for detecting an air-fuel ratio of an air-fuel mixture burned in the engine in accordance with an oxygen concentration in exhaust gas emitted from the engine; and a controlling module for controlling open and close of the electromagnetic valve based on an operating state of the engine. The controller controls at least one of a valve-open cycle, a valve-open period, and a valve-open amount of the electromagnetic valve based on a variation value of the air-fuel ratio detected by the air-fuel ratio detecting module when opening the electromagnetic valve.

  • 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.
