Abstract: A shaped object shaped by a shaping method includes a structure that is shaped by stacking plural constituent layers and a ceiling wall to support the structure. The structure includes plural spiral form parts. Each spiral form part has a cross section in an elliptic shape and extends in a stacking direction while turning with respect to a center position of the elliptic shape. The plural spiral form parts are disposed in matrix in a state where the center positions are separated from each other by a predetermined distance. The spiral form parts that are adjacently disposed in a row direction and a column direction are shaped so that the turning directions are opposite. In at least one cross section of the structure, the major axes of the spiral form parts that are adjacent in the row direction and the column direction are orthogonal to each other.

Abstract: Motor-generators are arranged both at front and rear wheels so as to be capable of using all of four wheels for regeneration. The horizontal axis indicates deceleration of a vehicle, and the vertical axis indicates braking forces for the front and rear wheels, respectively above and below the horizontal axis. A setting value indicates a limit braking force for the rear wheels to be locked. A frictional braking force and a regenerative braking force at the rear wheels are controlled so that the total braking force for the rear wheels does not exceed the setting value.

Abstract: An aluminum alloy casting free from crack-causing needle-shaped crystallized substances, and an apparatus and a method for producing a slide member excellent in mechanical properties such as abrasion resistance are provided. A melt of an iron-containing aluminum alloy poured into a vessel in the completely liquid state is vibrated by a vibrating needle of a vibration applying unit, and then a core is inserted into the melt to cool the melt, whereby the aluminum alloy casting is produced as a sleeve of a slide member. The vibrating step is carried out at a frequency of 20 to 1000 Hz, and is continued until just before the melt is cooled to the solid-liquid coexisting temperature region.
