Abstract: Disclosed is a power generation system including an attachment part to attach a fuel container which stores a fuel, a lock mechanism to detect a lock or a lock release of the fuel container which is attached to the attachment part and a data recording unit to record a data in a storage medium provided at the fuel container based on a detection of the lock release by the lock mechanism before the fuel container is detached from the attachment part.

Abstract: An objective lens drive device where a cushioning elastic body can be stably poured into a through-hole that is formed in a wire holder in which a suspension wire is inserted, and where the amount of the elastic body required is reduced. The through-hole that is formed in the wire holder (8) and in which the suspension wire (7) is inserted has a first elastic body receiving section (8a) formed on a lens holder (2) side, a second elastic body receiving section (8b) formed on a wire fixation member side so as to be adjacent to the first elastic body receiving section (8a), and a wire penetration hole (8c) for communicating the first elastic body receiving section (8a) and the second elastic body receiving section (8b) and having a smaller diameter than the first elastic body receiving section (8a).

Abstract: The objective lens driving device of the present invention for an optical pickup device is provided. The device includes first and second objective lenses, and a lens holder for supporting the first and second objective lenses. The lens holder has a first through-hole for passage of first laser beam and a second through-hole for passage of second laser beam. Where a plane defined by a central axis of the first objective lens and a central axis of the second objective lens is a central plane, a plane perpendicular to the central plane and including the central axis of the first objective lens is a first plane, and a plane perpendicular to the central plane and including the central axis of the second objective lens is a second plane; the first through-hole is asymmetrical with respect to the first plane and/or the second through-hole is asymmetrical with respect to the second plane.

Abstract: In order to obtain a preferred recording/reproducing characteristic in an apparatus for optical disks having higher density, an objective lens drive is provided for driving an objective lens (1) in the optical axis direction, a direction perpendicular to the optical axis, and a tilting direction along the radius of an optical disk, by which operating sensitivity is improved and a stable operating characteristic is realized. Sections of two (7b, 7e) of six fixing portions (7a to 7f) for supporting six support members (6a to 6f) which support a movable part (5), are set lower in stiffness than another sections of the other four fixing portions (7a, 7c, 7d, 7f), thereby improving the operating sensitivity of the movable part (5) and stabilizing the operation of the movable part (5).

Abstract: Tracking coils are attached to outer surfaces of two focusing coils. Inside the focusing coils, a first magnet and a second magnet are arranged respectively. A third magnet is arranged so as to face the first magnet and the second magnet via the tracking coils. An open end of a first yoke for holding the first magnet and an open end of a second yoke for holding the second magnet are connected by a bridging yoke. Since a magnetic flux is formed in the bridging yoke, pitching vibrations can be suppressed and a driving sensitivity improves owing to an increase in an effective magnetic flux.
