  • Fan noise control apparatus
    Patent number: 7762373
    Abstract: A fan noise control apparatus is provided to facilitate the reduction of noise. According to the preferred embodiments, an acoustically transparent portion is provided to permit noise from one source to pass through to interact and cancel with another noise.
    Type: Grant
    Filed: May 9, 2006
    Date of Patent: July 27, 2010
    Assignee: Sony Corporation
    Inventors: J. Stuart Bolton, Moohyung Lee, Kenichi Seki, Hiroto Ido
  • Micro mirror unit, optical disc drive using same, and method for producing micro mirror unit
    Patent number: 7215630
    Abstract: The hinge (13) should preferably be formed to have a higher resistance than ever against the pivoting of the mirror body (12) to effectively prevent the hinge (13) from being damaged. By adopting a suitable one of a variety of production steps as necessary, the hinge (13) can be formed more finely and with a higher precision and thus the micro mirror unit can be produced more easily in a shorter time. To this end, the hinge (13) is formed from a different material, such as SiNx, from the mirror substrate material from which the frame (11) and mirror body (12) are formed.

  • Micro mirror apparatus and optical memory disk apparatus
    Patent number: 6552991
    Abstract: In a micro mirror apparatus pivoting on a hinge part as its axis, a movable part connected to a stationary part through the hinge part enhances exclusively the flexural rigidity of the hinge part without causing any significant change in the torsional rigidity of the hinge part and thus widens servo band. To this end, on at least a part of the hinge part 14, a protrusion 14b protruding in the direction of its thickness is formed. This greatly increases the flexural rigidity of the hinge part 14 and widens the servo band.
