    Abstract: A camera captures an image of objects outside a vehicle through a window of the vehicle. An image processing unit determines whether a captured image captured by the camera is clear or blurred. A controller activates a window heater to raise a temperature of a window area if the image processing unit determines that the captured image is blurred. If a blurred state of the captured image is not reduced by a time that a predetermined period of time elapses since the window heater is activated, the controller suspends activation of the window heater when the predetermined period of time elapses and prohibits subsequent activation of the window heater.

  • Publication number: 20170138294
    Abstract: This invention relates to a control device for an internal combustion engine. An object of this invention is to prevent a deterioration in exhaust characteristics when a change to an air-fuel ratio on a theoretical air-fuel ratio side is requested in an internal combustion engine during operation in a lean mode. The control device controls an internal combustion engine equipped with a NOx storage-reduction catalyst in an exhaust passage. When a NOx amount stored in the NOx storage-reduction catalyst reaches a release threshold value, the control device executes rich control to cause the NOx to be released. In a state in which an air-fuel ratio of an air-fuel mixture belongs to a second region that is near a lean limit, the release threshold value for determining the start of the rich control is set in the vicinity of the NOx storage capacity of the NOx storage-reduction catalyst.

  • Publication number: 20170138727
    Abstract: It is possible to, with a position measuring apparatus in a NC machine tool, a NC lathe, or the like that uses a load monitoring scheme, significantly reduce a response delay on the detecting jig side than those in the conventional apparatuses, and consequently measure the position of a measurement target with high accuracy. A measurement target (e.g., an advanceable and retractable center) is caused to abut a position detecting jig at the advanced end of the measurement target. In such a state, retracting and advancing motions of the measurement target are created to increase the load torque of a feed motor to a level sufficiently higher than the load torque that is detectable by the apparatus. After that, the abutment state between the measurement target (center) and the jig is canceled to cause a sudden drop in the load torque of the feed motor.

  • Publication number: 20170140917
    Abstract: An adhesion liquid is supplied onto a front side of a wafer having a disk-shape while a rinse liquid is discharged onto a backside of the wafer that is rotating. The rinse liquid is discharged to a position close to a rotational center of the wafer and a position close to an outer peripheral edge of the wafer. The rinse liquid reaches an outer peripheral end surface of the wafer, and thus adhesion of the adhesion liquid to the outer peripheral end surface is reduced.

  • Patent number: 9651351
    Abstract: A gap assessment tool includes a base and an edge probe. The base fits to an exterior exhaust element of a vehicle, and includes the first of a pair of defined measurement locations. The edge probe is supported by the base for movement to an extended position in which, with the base fitted to the exterior exhaust element, the edge probe contacts an edge of an exterior body panel of the vehicle spaced from the exterior exhaust element, and includes the second of the pair of defined measurement locations. With the base fitted to the exterior exhaust element, and with the edge probe moved to the extended position and contacting the edge of the exterior body panel, a measurement between the pair of defined measurement locations is indicative of a part of a gap between the exterior exhaust element and the edge of the exterior body panel.

  • Patent number: 9650035
    Abstract: A control apparatus is applied to a hybrid vehicle. The hybrid vehicle includes an internal combustion engine and a second MG as driving sources, and a power split mechanism which is capable of changing and transmitting to an output portion transmitting torque to drive wheel, a rotating speed of the internal combustion engine. And, the hybrid vehicle is capable of switching a gear ratio mode of the power split mechanism between a variable gear ratio mode and a fixed gear ratio mode. The control apparatus determines whether or not a switching of the gear ratio modes is prohibited based on a vehicle speed and a gradient of a road. And, when it is determined that the switching is prohibited, the control apparatus maintains the gear ratio mode in the variable gear ratio mode or the fixed gear ratio mode.

  • Patent number: 9650037
    Abstract: The control unit of the fuel cell system monitors the status of power generation of the fuel cell and calculates a total amount of the fuel gas consumption, based on the amount of power generated by the fuel cell, from a point in time when the supply gas pressure reaches a standard gas pressure. Another total amount of the fuel gas consumption is calculated based on a gas pressure change that corresponds to a decrease of the gas pressure from the standard gas pressure. Comparing two total amounts of the fuel gas consumptions, the evaluation is performed as whether the on-off valve in the fuel gas flow path from each of the fuel gas tanks to the fuel cell fails to be opened.

  • Patent number: 9650248
    Abstract: Reagent complexes have two or more elements, formally in oxidation state zero, complexed with a hydride molecule. Complexation with the hydride molecule may be evidenced by shifts to lower binding energies, of one or more electrons in each of the two or more elements, as observed by x-ray photoelectron spectroscopy. The reagents can be useful for the synthesis of multi-element nanoparticles. Preparation of the reagents can be achieved by ball-milling a mixture that includes powders of two or more elements and a hydride molecule.

  • Patent number: 9650936
    Abstract: An object of the present invention is to detect an abnormality in an exhaust gas purification apparatus having an NSR catalyst and an SCR catalyst disposed on a downstream side of the NSR catalyst more favorably. Air-fuel ratio reduction control is executed to reduce NOx occluded to the NSR catalyst when an integrated value of an amount of NOx flowing into the NSR catalyst reaches an upper limit value of an amount of NOx that can be occluded to the NSR catalyst in a normal condition. It is determined whether or not the exhaust gas purification apparatus is in an abnormal state on the basis of a NOx purification ratio of the exhaust gas purification apparatus calculated at this time.
