  • Vehicle body structure
    Patent number: 8851558
    Abstract: A vehicle body structure of the present invention includes an elastic base frame formed in a ring shape; and three elastic upper frames each formed in a ring shape, the three upper frames being disposed on the base frame so as to configure a tetrahedron with the base frame, the three upper frames being connected to the base frame, and the upper frames that are adjacent to each other in a peripheral direction of the base frame being connected to each other. A vehicle body structure is hence provided capable of exhibiting high impact absorption properties.

  • Collision discriminating apparatus for vehicles
    Patent number: 6561301
    Abstract: A collision discriminating apparatus for vehicles having a collision detection device mounted on a part of the vehicle to detect the deformed amount of a collided portion deformed by collision of a collision object against the vehicle, and a collision object presuming device for presuming what object collided against the vehicle on the basis of the deformed amount of the collided portion detected, and the vehicle speed when the vehicle collided.

  • Force transducer
    Patent number: 4833929
    Abstract: A force transducer for detecting compression. The force transducer comprises an Si single crystal so formed as to have a crystal face of {110} as the surface to which compression is applied; a first pair of opposing electrodes provided on the Si single crystal in the direction having an angle of 45 degrees with the direction of <001> of the Si single crystal and a second pair of opposing electrodes provided on the Si single crystal in the direction having an angle of 45 degrees with the direction of <110> of the Si single crystal; a seat which is bonded to the crystal face of {110} of the Si single crystal and which transmits the compression substantially uniformly to the crystal face; and a base which is bonded to the surface of the Si single crystal opposite to the surface bonded with the seat and which supports the Si single crystal. The force transducer has a simple structure as a whole and is capable of detecting compression with accuracy.
