20150064600 | FUEL CELL ASSEMBLY AND METHOD OF MANUFACTURING SAME, AND BONDING PART MANUFACTURING METHOD AND DEVICE - The present invention relates to a fuel cell assembly and method of manufacturing same, and a bonding part manufacturing method and device. For instance, in a resin frame, a depression part is subsidence formed from a lower-end face toward an upper-end face, and a housing hole is pass-through formed from a top surface of the depression part toward the upper-end face. For instance, the depression part, a cathode-side electrode and an electrolyte film are housed, and in such a circumstance, an anode-side electrode is housed in the housing hole. A portion of the resin frame permeates a gas diffusion layer which configures the anode-side electrode and is a porous body. Via the permeated site, the resin frame and the gas diffusion layer (anode-side electrode) are integrally bonded. | 03-05-2015 |

20100080702 | WIND TURBINE GENERATOR AND ITS CONTROL METHOD - A wind turbine generator system is provided with a nacelle supporting a wind turbine rotor, a nacelle rotation mechanism, an anemometer, and a control apparatus controlling the nacelle rotation mechanism. Said control apparatus calculates the wind direction deviation from the wind direction measured by the anemometer and the direction of the wind turbine rotor. Said control apparatus performs a yaw rotation of the nacelle by the nacelle rotation mechanism when any of conditions (1) and (2) is satisfied; the condition (1) is a condition under which a state where the absolute value of said wind direction deviation is equal to or more than a first threshold value continues for a first duration predetermined, and the condition (2) is a condition under which a state where the absolute value of said wind direction deviation is equal to or more than a second threshold value larger than said first threshold value continues for a second duration shorter than said first duration. | 04-01-2010 |

20100270822 | MOUNTING STRUCTURE OF VEHICLE SEAT AND VEHICLE THAT INCLUDES MOUNTING STRUCTURE OF VEHICLE SEAT - In a mounting structure of a vehicle seat, a side member and a bracket that support a vehicle seat form an enclosed section. Because the rigidity of the side member and the bracket may be secured, the mounting rigidity of the vehicle seat may be secured and the weight of the side member and the bracket thereby reduced. A pair of sidewalls formed in the side member face each other in the vehicle lateral direction, and a pair of connecting walls formed in the bracket are connected to the pair of sidewalls while facing the pair of sidewalls. If a forward and upward load is applied to the vehicle seat due to a sudden reduction in vehicle speed, a shearing force acts on the sidewall and the connection wall in relation to each other. Thus, sufficient durability of the connecting part may be ensured. | 10-28-2010 |
