  • Patent number: 9327968
    Abstract: A work hardening treatment which decreases the Young's modulus, and an age hardening treatment which recovers or increases the Young's modulus decreased by the work hardening treatment are performed to form a vibrating portion, thereby attaining a vibrating element advantageous in downsizing while ensuring desired fatigue characteristics and vibration characteristics. This downsizes, for example, an actuator device, an optical scanning device, a video projection apparatus, and an image forming apparatus.

  • Patent number: 9024992
    Abstract: The oscillation element according to the present invention includes a torsion bar mounted on a base, and an oscillating member having a light reflection surface for reflecting light from a light source, which is fixed on the torsion bar protruding from the base. The oscillating member oscillates about a longitudinal axis of the torsion bar with an elastic deformation of the torsion bar, thereby deflecting the light that reflects at the light reflection surface in a direction intersecting the longitudinal axis. The oscillating member has two plates that are joined together so as to sandwich the torsion bar. On joining surfaces of the plates are provided with grooves for receiving the torsion bar, respectively. The plates have a symmetrical shape that the longitudinal axis serves as the axis of symmetry.

  • Publication number: 20140099804
    Abstract: A connector is mountable on a circuit board and mateable with a mating connector along a mating direction. The connector comprises a contact, a housing, an enclosing portion and a coupling portion. The housing holds the contact. The enclosing portion encloses an outer circumference of the housing in a plane perpendicular to the mating direction. The coupling portion directly or indirectly couples the enclosing portion with the housing so as to allow the enclosing portion to move along the mating direction relative to the housing.
