    摘要： The present invention discloses a cable-driven manipulator comprising an operating unit having a drive motor, and a pulley rotated by the drive motor. An upper arm is coupled, through a joint, to one side of the operating unit. A forearm coupled, through a joint, to the other side of the upper arm by the cable. A gripper of an end effector operably coupled to the forearm, a cable compensation device is installed between the upper arm and the forearm so as to maintain constant the length of the cable that transmits the power of the operating unit to the end effector during the pivoting of the forearm. It is thus possible to prevent the variation of tensile force due to the variation of the length of the cable for operating the end effector during the pivoting of the forearm or the unintended malfunction of the end effector.

    摘要： A method of manufacturing complex oxide nano particles includes preparing a mixed solution including at least one metal salt selected from the group consisting of aluminum salt, manganese salt and barium salt, impregnating an organic polymer having nano-sized pores with the mixed solution, and calcining the organic polymer impregnated with the mixed solution. Accordingly, complex oxides with particle sizes on the nanoscale can be prepared, and the kind and composition ratio of metal elements contained in the complex oxides can be facilitated. Also, a multilayer ceramic capacitor including the complex metal oxides manufactured by this method can ensure a super slim profile and high capacity.

    摘要： A laminated lens package and a method of fabricating the same are disclosed. The laminated lens package includes a first lens layer including a first lens element formed at one surface thereof through a first mold; a second lens layer including a second lens element formed at one surface thereof through a second mold, corresponding to a location of the first lens element; and a polymer layer provided between the first lens layer and the second lens layer. Accordingly, desired refraction can be implemented by controlling a refractive index. Also, since no spacers are used, defects caused by adhesion of an adhesive agent do not occur. Thus, a fabrication process is simplified, so that productivity can be improved and a fabrication cost can be reduced.
