  • Patent number: 8563189
    Abstract: A fuel cell system including a plurality of single-cell units, each of which include an electrolyte membrane disposed between an anode and a cathode and which generate electric power by a reaction of a fuel gas in the anode and an oxidizer gas in the cathode, and a fuel cell in-which the plurality of single-cell units are stacked. A plurality of voltage measurement devices measure the voltages of the single-cell units, respectively. A control unit determines the humidification state of the fuel cell based on the voltage of a second single-cell unit wherein when the voltage of the second single-cell is equal to or lower than an insufficient-humidification-determining voltage which is higher than the predetermined voltage the control unit determines that humidification of the fuel cell is insufficient, disposed in the vicinity of a first single-cell unit, the first single-cell unit having a voltage that is equal to or lower than a predetermined voltage.

  • Publication number: 20130110316
    Abstract: A driving assistance apparatus that assists driving of a vehicle, includes: a vehicle speed sensor; a communication unit that obtains traffic light information relating to a change in a display condition of a traffic light disposed in an advancement direction of the vehicle; a position calculation unit that calculates relative position information between the vehicle and a traffic light location where the traffic light is disposed; and a passage assistance control unit. The passage assistance control unit detects an operating condition of the vehicle at an intersection location before the traffic light, calculates a corrected vehicle speed on the basis of the operating condition and a current vehicle speed, and determines whether or not the vehicle is permitted to pass through the traffic light location on the basis of the corrected vehicle speed, the relative position information between the vehicle and the traffic light location, and the traffic light information.

  • Publication number: 20130110315
    Abstract: A driving assistance apparatus includes a target vehicle speed determination unit that obtains, on the basis of a current vehicle speed, the relative position information between a vehicle and a traffic light location, and the light information relating to a change in a display condition of a traffic light, an arrival timing at the traffic light location following travel at the current vehicle speed, and that determines a vehicle speed region in which the vehicle is permitted to pass through the traffic light location as a target vehicle speed region when the display condition at the arrival timing corresponds to a passage permitting display condition, or when the display condition at the arrival timing corresponds to a passage non-permitting display condition and a time remaining until the display condition changes from the passage non-permitting display condition to the passage permitting display condition is within a first threshold time.

  • Publication number: 20130110371
    Abstract: A driving assisting apparatus that assists in driving a vehicle includes: a vehicle speed sensor that detects a vehicle speed of the vehicle; a control unit that determines a recommended traveling state based on a current vehicle speed detected by the vehicle speed sensor and at least one of an accelerated vehicle speed when the vehicle accelerates from the current vehicle speed at an allowable acceleration and a decelerated vehicle speed when the vehicle decelerates from the current vehicle speed at an allowable deceleration; and an assisting unit that assists in driving the vehicle based on the recommended traveling state determined by the control unit.

  • Patent number: 7696014
    Abstract: A method for breaking an adhesive film mounted on the back of a wafer having a plurality of streets formed in a lattice pattern on the face of the wafer, and having devices formed in a plurality of regions demarcated by the plurality of streets, the devices being divided individually, is adapted to break the adhesive film along the outer peripheral edges of the individual devices, with the adhesive film being stuck to the surface of a dicing tape mounted on an annular frame. The method comprises: a laser processing step of projecting a laser beam with a pulse width of 100 picoseconds or less onto the adhesive film through gaps between the individually divided devices to form deteriorated layers in the adhesive film along the outer peripheral edges of the individual devices; and an adhesive film breaking step of exerting external force on the adhesive film having the deteriorated layers formed therein, to break the adhesive film along the deteriorated layers.
