  • Patent number: 10377421
    Abstract: In a vehicle-body structure in which a roof side rail portion of a side face portion of a vehicle body and a roof reinforcement are connected via a gusset so as to suppress that a center pillar portion comes into a cabin side when a large load is inputted from a vehicle side, a notch portion is provided at the gusset. Thereby, it is suppressed that, when the large load is inputted to the center pillar portion from the vehicle side, the gusset is so bending-deformed by a rotation of the roof side rail portion that a rotational moment caused by the rotation of the roof side rail portion acts on the roof reinforcement, suppressing that the center pillar portion comes into the cabin side.

  • Patent number: 7653458
    Abstract: A robot device, which autonomously performs actions, includes a moving unit that moves the robot device, and a target position acquiring unit that acquires position information of a target. A movement method judging unit receives an instruction for a movement from a user, and judges whether or not a destination can be designated by fixed position information. When it is judged that the destination can be designated by the fixed position information, control is performed by a position movement control unit. When it is judged that the destination cannot be designated by the fixed position information, control is performed by a target movement control unit, which acquires position information from the target position acquiring unit, to operate the moving unit.
