Abstract: In an optical motion capture system, it is possible to measure spatially high-dense data by increasing the number of measuring points. In the motion capture system using a mesh marker, intersections of lines for the mesh marker are called nodes and the lines connecting the nodes are called edges. The system includes a plurality of cameras for capturing a two-dimensional image of the mesh marker by imaging a subject having the mesh marker, a node/edge detecting section for detecting node/edge information on the mesh marker from the two-dimensional image captured by the respective cameras, and a three-dimensional reconstructing section for acquiring three-dimensional position information of the nodes by using the node/edge information detected from the plurality of two-dimensional images captured by different cameras.

Abstract: A storage device includes a storage medium; a rotating shaft; a head actuator pivotally supported about the rotating shaft; a head fixed at an end of the head actuator for reading/writing information from/to the storage medium; and a magnetic circuit having a magnetic member and a magnet connected thereto. The magnet has a magnetic characteristic corresponding to the inertia of the head actuator. The storage device further includes a coil fixed at the other end of the head actuator. The coil generates a driving force proportional to the inertia when an electric current is flown through the coil by interaction with the magnetic circuit. The driving force causes the head actuator to be driven to adjust the head to a target position on the storage medium. The magnetic member is configured as a single unit having a common dimension among a plurality of storage devices having different specifications.

The metal piece is attached in contact with a surface of the coil arm other than the one facing the stopper.

Abstract: A bolt temporary fixing nut 9, one axial end of which has a smaller diameter than a bolt hole of a bottom steel plate 1 and an outer peripheral surface of which is made into a tapered shape which is increased in diameter from the one axial end toward the other axial end so as to have a larger diameter than the bolt hole 3, is formed. The bolt temporarily fixing nut 9 is threadedly attached to the bolt 5, which is inserted through the bolt hole 3 from the bottom, and the one axial end of the nut is forcibly screwed into a gap between the bolt hole 3 and the bolt 5, thereby temporarily fixing the bolt 5 to the bolt hole 3 so as not to rotate. Thereafter, after the splice plate 2 is placed on the bottom steel plate 1, the nut 6 is fastened to the bolt 5, thereby joining the bottom steel plate 1 and a splicing plate 2. According to the invention, it is possible to prevent the bolt, which is hold in the bolt held in advance, from co-rotating at the time of nut fastening.

Abstract: A human-type link system, such as a humanoid robot having a dynamically feasible motion of the link system that is generated when a reference joint acceleration that is only calculated from a kinematical constraint condition is determined not feasible by an evaluation of external force computed based on an inverse dynamics calculation, or is generated by calculating from a dynamic constraint condition and a kinematical constraint condition simultaneously, the dynamic constraint condition is formulated by using an actuation space inverse inertial matrix that represents the relation of force acting on the link system and the acceleration of the link system caused by the force.

Abstract: A cover is received on the receiving surface of a base in a recording medium drive. A fastening mechanism serves to couple the cover to the receiving surface. An elastic member is interposed between the receiving surface and the cover. The elastic member is located along the occupied space of the fastening mechanism. The elastic member thus continuously surrounds the occupied space. When the cover is coupled to the base, the fastening mechanism urges the cover against the receiving surface of the base. Since the elastic member continuously surrounds the occupied space, the elastic member elastically deforms equally around the fastening mechanism. Flexure can thus be prevented in the base and the cover.

Abstract: A carriage arm assembly is disclosed that has a sub-assembly and a signal relay member that is arranged on a side surface of an arm portion of a carriage arm of the sub-assembly for connection between a head slider and a head IC. The signal relay member includes a wire, a wrapping portion that is formed from a synthesized resin mixed with a charging prevention agent, and two pairs of hooks that are projecting from the wrapping portion. When the hooks are in contact with the arm portion of the carriage arm, static electricity possessed by the signal relay member flows away through the carriage arm, and this prevents a magnetic head at the end of the head slider from being destroyed by the static electricity. In addition, the hooks are engaged with grooves on the signal relay member so as to position the signal relay member on the arm portion.
