A refrigerator may include a main body having a storage room, a door configured to open or close the storage room, a sensing lever configured to contact the door while the door is closed, where the sensing lever is movable in one of a first direction and in a second direction that is opposite to the first direction, a sensor configured to sense a movement of the sensing lever in one of the first direction and the second direction, and a controller configured to open the door when the sensor senses the movement of the sensing lever in the first direction, and to maintain the door closed when the sensor senses the movement of the sensing lever in the second direction.

Refrigerator and control method of refrigerator door

A refrigerator and a control method thereof are provided. The refrigerator includes a carbonated water producing apparatus configured to produce carbonated water by supplying water and carbon dioxide gas to a carbonated water tank, a user interface configured to display information of carbonated water concentration, and a control unit configured to control the carbonated water producing apparatus to produce the carbonated water according to the information of carbonated water concentration, wherein the user interface displays a set concentration of the carbonated water and a present concentration of the carbonated water.

Refrigerator and controlling method thereof

A disk mounting hub has a disk-mounting face formed at one end as a truncated conical surface of revolution symmetric about a central axis. A cylindrical inner hub member is coaxial with the hub body outside diameter and the surrounding mounting face. The inner hub member is adapted to receive a planar disk with a central opening. The mounting face is disposed at a hub face angle (&#x3c0;/2+/&#x2212;&#x3a9;) relative to the central axis. Hub face angle &#x3a9; is selected so that a disk clamping force F applied to an inner disk portion surrounding the opening bends a portion of the disk interior to the hub inside diameter to conform with the conical disk-mounting face. This interior bending portion reduces or eliminates the tendency of the outer disk portion to form an excessive conning angle &#x3a6;.

Conning motor hub surface to compensate disk conning angle for balanced head flying height on both sides of a disk in mirror abs hard disk drives

A hard disk hub has a disk-mounting face formed at one end as a truncated conical surface of revolution symmetric about the hub axis. A cylindrical inner hub member is coaxial with the hub body outside diameter and the surrounding mounting face. The inner hub member is adapted to receive a planar disk with a central mounting hole with disk inside diameter fitted around it. The mounting face is disposed at a hub conning angle (&#x3c0;/2+/&#x2212;&#x3a9;) relative to the hub axis. Hub conning angle &#x3a9; is selected so that a disk mounting force F applied to an inner disk portion surrounding the central mounting opening bends a portion of the disk interior to the hub inside diameter to conform contiguous facing relationship with the conical disk-mounting face. This interior bending portion reduces or eliminates the tendency of the outer disk portion to form an excessive conning angle &#x3b8;.

Conning motor hub surface method for hard disk drives

An actuator beam that can be incorporated into an actuator arm assembly of a hard disk drive. The actuator beam may include a dynamic absorber that extends from a distal end of the beam. The dynamic absorber may attenuate any resonant displacement in the actuator beam induced by a shock load that is applied to the hard disk drive.

Dynamic absorber for an actuator arm in a disk drive

A bumper that can be attached to an outer surface of a hard disk drive housing. The bumper may be constructed from a damping material that attenuates a shock load and dampens a resultant vibratory response of a shock event. The bumper may be snapped onto the disk drive housing without using external fasteners.
