  • Patent number: 7389571
    Abstract: Embodiments of the invention provide a retaining ring attaching device capable of improving assembling efficiency and a data storage device fabricating method. In one embodiment, a C ring attaching device included in a hard disk drive assembling apparatus expands a C ring, puts the expanded C ring on a pivot, and contracts the C ring on the pivot. The C ring attaching device moves chuck arms holding the C ring such that the C ring is moved so that a gap in the C ring moves away from the pivot while the C ring is being contracted.

  • Patent number: 6693757
    Abstract: An apparatus and method for adjusting balance in a disk drive, and a method for assembling a disk drive, enables the modification of dynamic balance reliably and efficiently. The apparatus adjusts balance in a hard disk drive having disks and a spindle which are assembled in a base. The acceleration to be applied from an actuator is made to act on the top end of the spindle through a holder plate in one accelerator, while the acceleration to be applied from an actuator is made to act on the base end of the spindle through the base in another accelerator.

  • Patent number: 5153451
    Abstract: A fail safe level shifter assures that, when an input signal voltage level falls below a given threshold voltage, the output is either a constant high or no signal at all. Additionally, a range of digital high signals having a voltage less than the given threshold voltage may be shifted by the fail safe level shifter. The fail safe level shifter expands the width of an N-MOS channel of conventional level shifters by placing two MOS switches in parallel. The resultant resistance allows the fail safe level shifter to register those high signals which are below the given threshold voltage. One-half of the level shifter has a N-MOS channel about one-half the width of a N-MOS channel in the other half of the level shifter. Therefore, the narrower half is unable to fully activate given the low input signals received. The fail safe level shifter thus assures that the output will be a constant high.
