The projecting portions are arranged in vicinities of nodes of the vibration, respectively. The friction member has a sliding surface formed of a curved surface with which the projecting portions come into contact. The pressurizing unit pressurizes the vibrator against the friction member with a pressurizing force. When the vibrator is vibrated, a driving force is generated in a tangential direction of the sliding surface by the vibration to drive the friction member relative to the vibrator, and each of the projecting portions generates an elliptic motion by the vibration. The elliptic motion is generated with an inclination at a predetermined angle with respect to the curved surface of the sliding surface.

  • Patent number: 10505332
    Abstract: Edge-emitting laser diodes having mirror facets include passivation coatings that are conditioned using an ex-situ process to condition the insulating material used to form the passivation layer. An external energy source (laser, flash lamp, e-beam) is utilized to irradiate the material at a given dosage and for a period of time sufficient to condition the complete thickness of passivation layer. A process for training (calibrating) a laser-based ex-situ conditioning system provides three-dimensional spatial alignment between the focused beam and a defined location on the edge-emitting laser diode surface, while also determining an optimum performance window (in terms of power density and exposure interval) for efficient and effective conditioning.
