  • Publication number: 20080074836
    Abstract: A bracket assembly for receiving at least one disk drive (40) includes an enclosure (10), a retaining bracket (30), and a connecting structure (312). The retaining bracket includes a pair of sidewalls (31, 32). The retaining bracket is attached to the enclosure at an edge of each sidewall. The connecting structure is defined in a first sidewall (31) of the sidewalls for attaching the first sidewall to the enclosure for altering a fixing relationship between the retaining bracket and the enclosure. The connecting structure is positioned near the disk drive, and away from the edge of the first sidewall. The method of assembling the bracket (30) to the enclosure (10) is also provided.

  • Publication number: 20070202712
    Abstract: An exemplary optical disc drive apparatus includes a guide shaft configured to movably support a pickup head, and an elastically deformable member. The elastically deformable member includes a main body, and a cantilever slanting up from a middle part of a front edge of the main body. The cantilever is broad at a lower portion thereof and narrow at an upper portion thereof, and the cantilever is for resiliently pressing a corresponding end of the guide shaft. The elastically deformable member reduces a stress surface between the cantilever and the guide shaft, and lengthens the life span thereof.

  • Publication number: 20070140836
    Abstract: A blower includes a fan blade assembly. The fan blade assembly includes a cylinder, fan blades, and damping ribs. The fan blades are fixed by an upper ring, a lower outer ring, and a lower inner ring. The cylinder is surrounded by the fan blades and coupled to the lower inner ring. The damping ribs are set between each two adjacent fan blades for enhancing structural integrity of the fan blade assembly thereby acting as a vibration damper of the fan blades when the blower operates at high-speed.
