摘要： A small-sized optical disc drive includes one voice coil motor magnet within which a tracking coil and two focusing coils are disposed such that the tracking coil straddles the two poles of permanent magnets that are adjacently disposed. The two focusing coils are disposed on either side of the tracking coil, with each of the two focusing coils being only disposed over one of the permanent magnets.

摘要： There is provided a compact optical disc apparatus having a small footprint actuator. A tracking coil of a swing arm-type actuator is disposed substantially perpendicular to an arm and on the opposite side to an optical disc loading slot with respect to the line connecting the center of rotation of the optical disc to the center of swing movement of the actuator. A pair of permanent magnets are disposed such that they face the tracking coil and they are opposite in polarity. The tracking coil is disposed on both the permanent magnets such that the tracking coil straddles the boundary of the pair of permanent magnets.

摘要： An electromagnetic coil system for driving control of a micro-robot includes pairs of X-axis and Y-axis Helmholtz coils whose winding central axes are placed on an X axis and Y axis respectively, a position recognition system that detects a position and direction of the micro-robot in a workspace, a controller that controls an amount of supply of electric currents flowing to the X-axis or Y-axis Helmholtz coils in order to control movement of the micro-robot based on information about the movement of the micro-robot and previously input information about a path of the micro-robot, and a current amplifier that supplies the electric currents to the respective Helmholtz coils. The pairs of X-axis and Y-axis Helmholtz coils are disposed so as to face each other, and the X-axis Helmholtz coils and the Y-axis Helmholtz coils are vertically crossed and installed so as to form the workspace of the micro-robot.

摘要： The present invention provides a device for generating and varying stiffness, which may be applied to a joint of a robot manipulator. The stiffness generating device of the present invention, comprises: a rotating shaft connected to a driven member; a rotor fixed to the rotating shaft and having arms comprising a magnetic element; a stator disposed to surround the rotor outside the arms and being connected to a drive motor; electromagnets fixed to an inner periphery of the stator and being opposed to each other about the rotating shaft, each having a core and a coil wound around the core; and means for applying current to the coils. One half of the electromagnets has N-poles at their inward ends and the other half of the electromagnets has S-poles at their inward ends. Current regulating means regulates the current being applied to the coils.
