  • Patent number: 12565005
    Abstract: A three-dimensional modeled object to be manufactured by additive manufacturing includes a plurality of segments, a hinge structure that couples two adjacent segments among the segments, and a fitting structure including an external fitting portion and an internal fitting portion. The external fitting portion is configured to fit to the internal fitting portion. The three-dimensional modeled object is configured to be displaced between a folded position and an assembled position by the hinge structure. The assembled position is a position in which the three-dimensional modeled object is assembled from the folded position. The three-dimensional modeled object is held in the assembled position by fitting the external fitting portion to the internal fitting portion when the three-dimensional modeled object is in the assembled position.

  • Publication number: 20260024711
    Abstract: In a switch system including a set temperature UP switch that raises a set temperature of an air conditioner unit and a set temperature DOWN switch that lowers the set temperature, when a stuck-ON determination unit determines that only the set temperature UP switch is in a stuck-ON state, a stuck-ON recognition unit also sets the set temperature DOWN switch as being in a stuck-ON state. This makes it possible to eliminate a malfunction caused by only one of the switches becoming stuck ON.

  • Patent number: 8096611
    Abstract: A vehicle front-part structure comprises a radiator support upper (5) which extends in a vehicle width direction in a vehicle front, a cowl (9) which is coupled to an apron upper member (2) provided on a side in the vehicle width direction and extending in a vehicle lengthwise direction, and which is located to rearward of the vehicle (1) further than the radiator support upper, and a hood framework (21) which constitutes a part of the hood inner panel (17). The hood framework extends in the vehicle lengthwise direction, the hood framework is disposed between the radiator support upper and the cowl such that at least a part of a front end-face (21a) faces the radiator support upper and at least a part of a rear end-face (21b) faces the cowl.

  • Patent number: 7766420
    Abstract: The present invention aims at providing a vehicle body front-part structure which can efficiently disperse an impact load acting on the front part of a vehicle. In the vehicle body front-part structure in accordance with the present invention, a portion 6a of a radiator support supporting an upper part of a radiator arranged in the front part of a vehicle 2 is connected to a skeleton 9 of the vehicle body by a pair of first radiator support supporting members 4 which support it from both sides in the vehicle width direction, and second radiator support supporting members 11, 12 which are arranged on the inner side of the pair of first radiator support supporting members 4 in the vehicle width direction and support it from the backside.
