Appl. No.:

10/057201

Inventors:

Kelly Williams - Brentwood CA

Assignee:

Samsung Electronics Co., Ltd.

International Classification:

G11B 554

US Classification:

360256, 3602564, 3602651

Abstract:

A latch for securing an actuator arm of a hard disk drive. The latch has a catch portion that can engage a latch portion of the actuator arm. The latch also has a pusher portion and a crash stop portion that engage the actuator arm during movement into a latched position and prevent the latch from rebounding away from the arm. The pusher and crash stop portions eliminate the need for a separate crash stop in the disk drive. Eliminating the separate crash stop component reduces the complexity and cost for mass producing the disk drive.

US Classification:

360 9701, 360 9702

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.

International Classification:

G11B017/02

US Classification:

360/097010

Abstract:

An external bumper that is attached to the housing of a hard disk drive. The disk drive may include a disk that is attached to a spin motor. The spin motor may be mounted to a base plate. An actuator arm assembly may also be mounted to the base plate and coupled to the disk. The disk is enclosed by a cover that is attached to the base plate. Elastomeric bumpers are attached to the corners of the cover and the base plate. The bumpers absorb shock loads that are applied to the hard disk drive. By way of example, if the disk drive is dropped on an external surface the bumpers will make contact with the surface and absorb the impact load applied to the drive.

International Classification:

F24B 1/18

US Classification:

126512000

Abstract:

A sauna fireplace assembly that includes an outer enclosure, a combustion chamber enclosure, and a housing. The combustion chamber enclosure is positioned within the outer enclosure and defines a combustion chamber wherein heat is generated. The housing is positioned in contact with a panel of the combustion chamber enclosure and is configured to house a plurality of heat retaining members. An opening into the housing is accessible through the outer enclosure for access to the heat retaining members. Heat generated in the combustion chamber is passed to the heat retaining members and then radiated from the heat retaining members into a living space such as a sauna enclosure. A portion of the housing may be exposed within the combustion chamber for improved heat transfer to the heat retaining members.

Assignee:

Hearth & Home Technologies - Lakeville MN

International Classification:

F24B 1/187

US Classification:

126503000

Abstract:

A monitoring and control system for use with a decorative heating appliance such as a fireplace, stove, or fireplace insert. The monitoring and control system includes a sensor module, a computer system, a controller, and a communication system. The sensor module is configured to monitor a burner, gas valve, and ignition system of the heating appliance and generate monitoring signals. The controller is configured to generate fault condition signals based on the monitoring signals. The communication system is configured to communicate the fault condition signals to the computer system, wherein the computer system is located remotely from a living space within which the heating appliance resides. The computer system is configured to generate control signals in response to predetermined fault condition signals and communicate those signals to the controller via the communication system for control of at least one of the burner, gas valve, and ignition system or other functions of the heating appliance.

Tho Pham - Milpitas CA

Assignee:

Samsung Electronics, Inc. - Richfield Park NJ

International Classification:

G11B 1702
F16F 1522

US Classification:

360 9807

Abstract:

A balanced spin motor assembly of a hard disk drive. The spin motor includes a spindle that is mounted to a base plate of the disk drive by a plurality of mounting screws that are attached to mounting holes of the spindle and base plate. At least one recording disk is attached to a hub assembly that rotates relative to the spindle. The hub assembly contains magnets that are coupled to a coil located within the motor. Energizing the coil with a current creates a torque that rotates the hub and spins the disks. The hub assembly has a plurality of equally spaced threaded apertures located at a top portion and a bottom portion of the hub. The spin motor can be balanced by attaching weight screws to the threaded apertures of the hub. Weight screws can be attached to the bottom portion of the hub through the mounting holes of the base plate and the spindle. Accessing the hub through the mounting holes allows the spin motor to be dynamically balanced while attached to the base plate of the drive.

Tho Pham - Milpitas CA

Assignee:

Samsung Electronics, Inc. - Richfield Park NJ

International Classification:

G11B 554

US Classification:

360105

Abstract:

A crash stop is used for an actuator arm of a hard disk drive. The crash stop includes a base portion that is pivotally connected to a post that separates the magnets of a voice coil motor. Extending from the base portion is a tab portion that can be rotated between a first position and a second position. When in the second position the tab limits the movement of the actuator arm so that the sliders of the disk drive cannot move off of the disks. The actuator arm, voice coil motor and crash stop can be installed by initially placing the crash stop in the first position and orienting the actuator arm in an off disk position. The actuator arm and voice coil motor are then mounted to a base plate of the disk drive. The actuator arm is rotated to load the magnetic heads onto the disks of the disk drive. The crash stop is then rotated to the second position and a cover is subsequently attached to the base plate to enclose the assembly.

International Classification:

G11B 554

US Classification:

360105

Abstract:

A latch for an actuator arm of a hard disk drive. The latch includes a damping sleeve that is molded onto a steel plate. The sleeve has a pair of collars located at opposite ends of a neck portion. The neck portion is inserted into a plastic fantail portion of an actuator arm. The steel plate becomes attached to a magnetized member of the drive when the actuator arm is rotated to an unloaded position. The attachment of the plate, latches the position of the actuator arm and prevents the disk drive heads from moving onto the data sectors of the disk. The latch is located on the longitudinal center axis of the actuator arm so that the latch does not create a twisting vibrational mode on the arm. The steel plate is located away from the voice coil magnets of the disk drive so that the latch does not create a biasing force on the arm. The latch can be assembled to the actuator arm by merely pressing the damping sleeve into an aperture of a tab that extends from the fantail of the arm.
