    摘要: L'invention se rapporte à une tête optique dans un dispositif d'enregistrement-lecture d'un support d'informations.
    Une telle tête optique comporte un miroir pivotant (2) permettant de renvoyer la lumière vers le support d'informations (4). Selon l'invention, ce miroir pivotant est monté sur ine assise pivotante (26) possédant une surface de glissement et reposant sur la surface de glissement (30) d'un socle en forme de berceau. Le miroir (2) est monté sur l'assise (26) de telle façon que le centre de courbure des surfaces de glissement soit dans le plan réflecteur du miroir (2). Le réglage de l'orientation du miroir est donc rendu aisé.
    L'invention s'applique notamment à un energistreur- lecteur de disque optique.

    摘要: An optical switching assembly having an optical path therethrough includes an optical element, a base frame, an optical support that supports the optical element and is pivotably mounted to the base frame, and a linkage. The linkage interconnects the base frame and the optical support to effect movement of the optical support between an aligned position where the optical element is in the optical path and a non-aligned position removed from the aligned position. The linkage has two over-center positions that respectively correspond to the aligned position and the non-aligned position. No additional energy is required to hold the linkage in the over-center positions.

    摘要: A piezoelectric actuator with integrated features to provide coarse position adjustment of a pushing threaded rod and also mechanically amplified piezo motion for fine position adjustment is presented here in three design variants. The mechanical amplifier houses one or more piezo stacks in longitudinal axis with preload to translate an amplified motion in the order of a few times in the transverse axis, perpendicular to the piezo stack motion. The piezo amplifier output travel is transmitted to the threaded rod with a ball at the end to push a desired surface for position adjustments and motion translation in application such as a mirror mount.

    摘要: An actuator device (10) includes a motor (12) and a reduction device (14) operatively coupled to the motor (12) and oriented about a central axis (20). The reduction device (14) is configured to modify an input angle of rotation provided by the motor (12) to an output angle of rotation. Further included is a rotary flexure mechanism (30) that includes a rotary flexure (32) operatively coupled to an output portion of the reduction device (14). The rotary flexure mechanism (30) also includes a plurality of flexure blades (36) coupled to the rotary flexure (32), each of the flexure blades (36) angularly oriented from the central axis (20). The rotary flexure mechanism (30) further includes a diaphragm flexure pair (40,44) operatively coupled to the flexure blades (36). The diaphragm flexure pair (40,44) comprises a rotational and in-plane stiffness greater than an axial stiffness resulting in the rotary flexure mechanism (30) being configured to convert a rotational input to an axial translation.
