A polymer electrolyte which comprises an ionic liquid (A) and a block copolymer (B) as essential ingredients, which block copolymer (B) comprises one or more of polymer block(s) (P) being compatible with (A) and one or more of polymer block(s) (Q) being incompatible with (A). (A) and (P) mutually dissolve each other to form one phase (X), and (Q) forms a phase (Y) being incompatible with phase (X), and phase (X) and phase (Y) are mutually micro phase separated. The polymer electrolyte of the present invention shows practical ion conductivity, is excellent in retention of ionic liquid, and moreover, is also excellent in heat resistance and mechanical strength. Furthermore, the electrochemical device and actuator element of the invention are swiftly displaced in accordance with application of a voltage, and can be actuated stably for a long period due to the liquid-retaining property and mechanical strength of the polymer electrolyte used, and, therefore, can suitably be used in the fields of medical instruments, micro-machines, industrial robot, personal robot, etc.

An atomic beam control apparatus controls a position of an atomic beam that passes through a multi-pole magnetic field by irradiating the atomic beam with a light beam. The apparatus includes a probe light generator to generate probe light to detect a position of the atomic beam, a light sensor to receive the probe light, and a current control section to control a current flowing in multi-pole magnetic field generating electrodes controlling the position of the atomic beam. The light beam irradiates the atomic beam so that the atomic beam interacts with both the light beam and the magnetic field, and the position of the atomic beam is controlled by controlling currents fed to the multiple-pole magnetic field generating electrodes based on output values of the light sensor receiving the probe light.

An optical disk apparatus comprises an optical pickup for directing a light beam onto pits formed in an optical disk and for receiving reflected light from the optical disk, an optical pickup supporting member including two guide rods for guiding the optical pickup in a radial direction of the optical disk, two first mounting members for mounting ends of one guide rod, and two second mounting members for mounting ends of the other guide rod, a chassis for mounting the first and second mounting members, an optical pickup driving mechanism including gears and a motor to move the optical pickup in a radial direction of the optical disk, a turntable on which the optical disk is located, and an optical disk drive motor for rotating the turntable. Each of the first fixing members includes a base fixed to the chassis, a guide rod supporting member for fixedly supporting the guide rod, and a flexible member located between the base and the guide rod supporting member for causing the guide rod supporting member to be displaced in a vertical direction with respect to a surface of the optical disk. A natural frequency of a system consisting of the one guide rod, the first mounting member and the chassis is set to be less than that of the optical pickup and of the optical disk.
