A multimedia information arranging apparatus that utilizes various feature values contained in multimedia information, carries out a flexible retrieval and classification and displays the information in an information set arrangement space is provided. A transfer mechanism loads, unloads and transfers workpieces between a machining spindle and the auxiliary spindle thereby enabling simultaneous cutting and chamfering andor deburring processes to be carried out. The solenoid ring is formed by annular solenoids that can be actuated in turn in the circumferential direction of the solenoid ring by the commutation electronics. The method includes determining, for a third entity, a third value for the first aspect, the third value determined using at least the determined second value. The magnet assembly is fixed on the inner surface. The entire interval is gravel packed at one time followed by packer actuation and then selective opening of ports to conduct a fracture operation in any of the zones defined by the set packers and in any desired order.
