  • Patent number: 8547313
    Abstract: A driving apparatus includes a voltage applying unit, a light irradiation unit and a resistance control unit. The voltage applying unit forms a voltage applying circuit together with a pair of electrode layers of a photo-addressing type display element. The voltage applying unit applies a voltage between the pair of electrode layers. The light irradiation unit irradiates the photo-addressing type display element with addressing light. The resistance control unit controls a resistance to a current which flows in a direction to reduce a potential difference between the pair of electrode layers to be larger than that during a period in which the voltage applying unit is applying the voltage.

  • Patent number: 8418788
    Abstract: A vehicle 1000 is equipped with a fuel cell system 100 and a secondary battery as power sources. A water level of water present on a water-covered road surface is measured by a water level sensor 72. When the measured water level reaches or exceeds a preset threshold value, drive control of the vehicle 1000 stops power generation by a fuel cell stack 10, closes a discharge valve 62, and enables the vehicle 1000 to be driven with output power of a motor that is actuated with electric power from the secondary battery. This arrangement effectively prevents a damage or failure of the fuel cells mounted on the vehicle moving on the water-covered road.

  • Patent number: 8361675
    Abstract: A vehicle 1000 has two pipings 60 and 62 arranged to discharge an exhaust gas from a fuel cell stack 10 to the outside of the vehicle 1000. An outlet provided at an end of the piping 60 is located at an underfloor position in a rear portion of the vehicle 1000, while an outlet provided at an end of the piping 62 is located at a roof rear end of the vehicle 1000. When the outlet provided at the end of the piping 60 is blocked or when there is a potential for such blockage, the outlet provided at the end of the piping 62 is used to discharge the exhaust gas from the fuel cell stack 10 to the outside of the vehicle 1000. This arrangement ensures continuous drive of the vehicle 1000 even in a specific environment where any of various obstructing objects as the cause of blockage of the outlet is present in the surroundings of the vehicle 1000.
