Abstract: A casting apparatus for manufacturing a cast product from molten metal includes a molten metal and a cooling portion. The molten metal contacts a surface for contact with the molten metal. The cooling portion forms a cooling flow passage. The cooling flow passage is configured to cool the molten metal contacting surface. At least a part of an inner surface of the cooling flow passage is constituted of a welding portion formed by welding, the welding portion sealing the cooling flow passage. The welding portion is constituted such that an exposure to the molten metal becomes equal to or less than a predetermined ratio with respect to an area of the welding portion constituting the inner surface of the cooling flow passage.

Abstract: Collision safety control device having a ground wire connected to a plurality of portions of a vehicle body frame, in which two of the plurality of portions may be mutually separated by more than a width of the frame and the ground wire may include a first portion connecting the collision safety control device to the cab and a second portion connecting the cab to the frame.

Abstract: For achieving a collision safety control device having improved a reliability of airbag deployment at an offset collision or the like without providing a contact part with a cab, a ground wire is connected to a plurality of portions of a vehicle body frame, in which two of the plurality of portions may be mutually separated by more than a width of the frame and the ground wire may comprise a first portion connecting from the collision safety control device to the cab and a second portion connecting from the cab to the frame.

Abstract: A shape memory alloy consisting essentially of, by weight ratio, 2 to 15% aluminium, 0.01 to 3% beryllium and the balance being substantially copper, with impurities being inevitably present in the process of preparation, and a shape memory alloy further including 0.05 to 15% zinc, both including composition ranges which allows cold work.
