  • Patent number: 8449004
    Abstract: A cylindrical lock includes a retractor mounted between inner and outer operational devices and operably connected to a latch. The retractor includes an upper surface having an upper recess. The retractor further includes a lower surface having a lower recess. Two upper compartments are defined in two sidewalls of the upper recess and extend to two lateral surfaces of the retractor, forming two upper tongues. Two lower compartments are defined in two sidewalls of the lower recess and extend to the lateral surfaces of the retractor, forming two lower tongues. First and second rollers are rotatably received in the upper and lower recesses, respectively. A size of an opening of each of the upper and lower compartments is reduced by pressing a distal end of each upper tongue downward and by pressing a distal end of each lower tongue upward, retaining the first and second rollers in place.

    Abstract: A cylindrical lock includes a retractor (131) mounted between inner and outer operational devices (10, 12) and operably connected to a latch (779). The outer operational device (12) includes an outer chassis (305), an outer lining (353) mounted around the outer chassis (305), and an outer spindle (379) received in the outer chassis (305). The outer spindle (379) includes an inner end (391) received in a pivot hole (375) of the outer lining (353). A restraining protrusion (397) is formed on an outer periphery of the outer spindle (379) and abuts an abutment face (376) of the outer lining (353), avoiding movement of the outer spindle (379) away from the outer chassis (305) in a longitudinal direction while allowing pivotal movement of the outer spindle (379) in a correct position.

  • Patent number: 8199439
    Abstract: This application discloses a hard disk drive comprising a landing ramp mounted to a disk base including a slider limiter for at least one slider in the hard disk drive to limit movement of the sliders during a non-operational shock event while parked on the loading ramp. Each of the slider limiters includes a clearance zone configured so that when the slider contacts the slider limiter during the non-operational event, the read-write head remains out of contact with the slider limiter. The clearance zone may include a recess and/or a cutout. The clearance zone may include a recess and/or a cutout. The recess may take any shape, for example the recess may be a polygon and/or curved in cross section. The polygon may have at least two sides. The clearance zone may further include a radial bulge to further protect the read-write head during non-operational shock events.

  • Patent number: 8189287
    Abstract: A disk hard disk drive that includes a spindle motor and an actuator arm coupled to a base plate. A plurality of disks are coupled to the spindle motor and a plurality of heads are coupled to the actuator arm and the disks. The drive also includes a cover attached to the base plate. The cover and base plate enclose a hard disk area that has a horizontal center line. The hard disk area includes a volume of air above the horizontal center line that is equal to a volume of air below the horizontal center line. The air space within the hard disk area is equal and symmetrical in a vertical direction. Such an arrangement reduces track mis-registration when servo is copied from a disk surface to the other surfaces of the disks in the drive.

  • Patent number: 7715179
    Abstract: A power supply includes a casing mounted in a computer housing, a power module disposed in the casing, and an electrical socket and a switch module embedded in an exposed side wall of the casing. The switch module includes an operating unit mounted movably in a mounting seat, and operable so as to move among a first position adjacent to the side wall, where two terminal units coupled respectively to the electrical socket and the power module disconnect electrically from each other such that the switch module is in an OFF mode, a second position distal from the side wall, and a third position between the first and second positions, where a conducting member contacts electrically the terminal units such that the switch module is in an ON mode. When the switch module is switched from the ON mode to the OFF mode, the operating unit is moved from the third position to the first position via the second position.
