Abstract: A rotor includes: a shaft having a tubular shape; and a rotor core including a through hole into which the shaft is inserted and that has a regular polygonal shape. The shaft is fixed to the rotor core by hydroforming. Of an outer peripheral surface of the shaft, a core contact part that is in contact with the through hole of the rotor core that has the regular polygonal shape has a shape extending along the regular polygonal shape.

Abstract: In a long member bending apparatus having a bending head and a material supply unit, the bending head is composed of a base plate having a guide pipe, which includes a guide hole for passing a long member, at the center thereof, a movable plate having a die, which applies a bending force to the long member supplied from the guide pipe forward, disposed at the center thereof, and six extendable units including hydraulic cylinders interposed between the base plate and the movable plate and universal joints disposed to both the ends of each hydraulic cylinder, thereby a parallel link mechanism is arranged that executes a motion of a total of six degrees of freedom including three degrees of freedom of translational movement and three degrees of freedom of rotation by expanding and contracting the hydraulic cylinders to set the position (distance, offset), inclination, and the like of the movable plate with respect to the base plate.

Abstract: The data, as read out from a trunk database, and the read-out data, as processed, are stored in a public database. A setup unit and an operations support unit manage the stored data of the public database and the attribute data of the stored data by a dictionary. In accordance with a demand of a user, an inquiry unit processes and displays the data on the basis of the data stored in the public database and the attribute data.
