    摘要： In a rotary actuator including a voice coil motor having a coil fitted to the other end portion of a carriage fixed to a rotary shaft and having a load at one of the end portions thereof, the rotary actuator of the present invention is characterized in that the rotation on the coil side and the rotation on the load side with respect to the rotary shaft are balanced. The weight of the coil is adjusted by forming the coil by at least two kinds of coil wires having different specific gravities, and where a plurality of coils are disposed on the outer side of the rotary shaft, the weight of the coil on the load side is made smaller than that of the coil on the opposite side.

    摘要： A magnetic disk apparatus includes a magnetic disk, a magnetic head which performs information recording and reproducing for the magnetic disk, a load spring for supporting the magnetic head, a head arm for fixing the load spring, a housing for housing these components, a shaft which fixes the head arm, bearings for supporting the shaft rotatably on the housing, and a motor which is coupled to the shaft. The motor comprises a motor cover, a permanent magnet which is divided into a plurality of segments and fixed on the shaft, and a coil which is fixed on the interior surface of the motor cover by being spaced with a certain gap from the permanent magnet. The shaft is included with a counter weight so as to complement the weight of the head arm, load spring and magnetic head. The coil has linear conductor sections parallel to the shaft, with the total number of linear sections being set equal to the total number of segments of permanent magnet.

    摘要： An apparatus and method for manufacturing a carbonaceous material are provided. The carbonaceous material manufacturing apparatus includes a reaction tube and a gas supply portion. An anode and a cathode defining an arc discharge portion is placed in the reaction tube, and a capturer is located provided as well to capture carbonaceous materials generated. At the location of the capturer, an RF heater is disposed around the reaction tube. In a carbonaceous material manufacturing method, carbonaceous materials generated in the arc discharge portion are transported from a gas supply portion into the reaction tube by the gas supplied into the reaction tube, then heated by a RF heater in the capturer where the carbonaceous materials are not exposed to the atmospheric air, to thereby promote removal of impurities and growth of single-walled carbon nanotubes.
