  • Patent number: 11965444
    Abstract: A controller for an internal combustion engine is configured to execute a determination process that determines that a deviation between a first change amount and a second change amount during a fuel cutoff operation is less than or equal to a threshold, and an anomaly diagnosing process that determines that an exhaust purification device is in a detached state when the determination process determines that the deviation is less than or equal to the threshold. The first change amount and the second change amount are change amounts per unit time of the temperature of exhaust gas on the upstream side and the downstream side of the exhaust purification device, respectively. The controller is configured to interrupt the determination process when the upstream-side temperature increases within a determination period.

  • Patent number: 11942645
    Abstract: A non-aqueous electrolyte secondary battery includes a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode. The separator has a multilayer structure in which a first filler layer containing phosphate particles, a porous resin substrate, and a second filler layer containing inorganic particles having higher heat resistance than the phosphate particles are stacked in this order from the negative electrode side. The first filler layer is disposed on the porous resin substrate in such a manner that the surface of the first filler layer faces the surface of the negative electrode. The phosphate particles have a BET specific surface area in the range of 5 m2/g or more and 100 m2/g or less.

  • Patent number: 10625569
    Abstract: An engine controller includes a reading section and a ratio-setting control section. The reading section is included in an air conditioner. The air conditioner draws an air into an air-conditioner housing, heats the air by a cooling water cooling the engine, and blows the air into a vehicle compartment. The reading section reads a state information that relates to a state of the air conditioner having an effect on an outside-air drawing ratio. The outside-air drawing ratio is a ratio of a volume of an outside air to a total volume of the outside air and an inside air. The ratio-setting control section decreases an amount of heat generated by the engine when the outside-air drawing ratio is a second ratio, which is smaller than a first ratio, to be smaller than an amount of heat generated by the engine when the outside-air drawing ratio is the first ratio.

  • Publication number: 20180272835
    Abstract: A vehicular air conditioning device includes a cabin air conditioning unit having a cabin side ventilator and a temperature adjusting unit, and a seat air conditioning unit having a seat side ventilator a ventilation duct that guides at least a portion of the air temperature adjusted by the temperature adjusting unit toward the seat side ventilator. A plurality of seat side blowout portions in a seat. The plurality of seat side blowout portions include a contact side blowout portion which is formed on a surface of a portion of the seat which come into contact with a passenger when the passenger sits in the seat, and a below knee side blowout portion which is formed on a portion of the seat that faces a below knee region of the passenger.

  • Patent number: 8354177
    Abstract: This invention provides a surface-coated cutting tool which exhibits excellent fracture resistance and wear resistance in high-speed cutting, such as high-speed gear cutting, high-speed milling, and high-speed drilling. The surface-coated cutting tool includes a hard coating layer composed of an alternately laminated layer structure of at least a thin layer A and a thin layer B formed on the surface of a tool substrate, such as a cemented carbide substrate, a cermet substrate, and a high-speed tool steel substrate. The thin layer A is an (Al, Cr, Si)N layer which satisfies a compositional formula: [AlXCrYSiZ]N (0.2?X?0.45, 0.4?Y?0.75, 0.01?Z?0.2, and X+Y+Z=1 in terms of atomic ratio). The thin layer B is an (Al, Ti, Si)N layer which satisfies a compositional formula: [AlUTiVSiW]N (0.05?U?0.75, 0.15?V?0.94, 0.01?W?0.1, and U+V+W=1 in terms of atomic ratio).
