20120102508 | DISK DRIVE INCLUDING A NOISE REDUCTION UNIT AND METHOD OF REDUCING NOISE BY USING THE DISK DRIVE - A disk drive that includes a noise reduction unit, and a method of reducing noise by using the disk drive. The disk drive includes a main chassis; a tray operatively coupled to the main chassis such that the tray is slidable relative to the main chassis, the tray including a disk accommodation portion configured to accommodate a storage medium such that the storage medium is rotatable relative to the disk accommodation portion; and a noise reduction unit configured to reduce a pressure concentration on an end portion of the storage medium as the storage medium rotates to reduce noise. | 04-26-2012 |
20120187510 | METHOD FOR FABRICATING MAGNETIC TUNNEL JUNCTION - A method for fabricating a magnetic tunnel junction element includes forming a magneto resistance layer including a first magnetic layer, an insulation layer and a second magnetic layer on a substrate, forming a magnetic loss area by doping a magnetic loss impurity into a region of the magneto resistance layer to cause a magnetic loss, and etching the magnetic loss area to form a magnetic tunnel junction element. | 07-26-2012 |
20120297402 | COVER FOR AN OPTICAL DISC DRIVE AND OPTICAL DISC DRIVE HAVING THE SAME - A cover for an optical disc drive. The cover includes: a body having a top portion that is configured to cover a disc if the disc is inserted into the optical disc drive, and a pressure structure formed on the body and having an asymmetrical shape. | 11-22-2012 |
20130269396 | WASHING MACHINE HAVING DAMPING APPARATUS - A washing machine having a structure in which a drum can stably rotate. The washing machine includes a cabinet including an outer frame that constitutes an exterior, an inner frame connected to an inner side of the outer frame, and a lower frame coupled to a lower part of the outer frame; a drum rotatably disposed in the inner frame; a base plate coupled to a lower part of the drum; a driving unit coupled to the base plate and driving the drum; and a damping apparatus that connects the base plate and the lower frame so as to absorb vibration occurring while the drum rotates. | 10-17-2013 |
20140033772 | WASHING MACHINE - A washing machine comprising a cabinet including an outer frame defining an appearance and an inner frame at least partially connected to an inner surface of the outer frame and a drum having a cylindrical shape and rotatably disposed in the inner frame. The inner frame includes a water flow disturbing part to disturb water flow generated in a space formed between the drum and the inner frame when the drum is rotated. The water flow disturbing part may have a shape that at least a portion of the inner frame protrudes outwardly along a periphery of the inner frame so that a length of at least one gap between an inner surface of the inner frame and an outer circumferential surface of the drum is different from a length of another gap. Accordingly, the drum may be stably rotated without collision with the frame in a dehydration process. | 02-06-2014 |
20140373672 | BALANCER AND WASHING MACHINE HAVING THE SAME - A balancer of a washing machine having improved balancing performance. The balancer includes a balancer housing having an annular channel therein, at least one mass movably disposed in the channel at least one groove recessed in an inner surface of the balancer housing so as to accommodate the mass, and at least one magnet coupled to an outer surface of the balancer housing to restrict the mass accommodated in the groove when an RPM of the drum is within a specific RPM range. The magnet is configured as a plurality of N poles and S poles which are arranged alternately, and the outermost pole of the magnet among the plural N poles and S poles has a relatively shorter length than another adjacent pole. | 12-25-2014 |
20150013077 | WASHING MACHINE WITH BALANCER AND CONTROL METHOD THEREOF - A washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum and a control method thereof. The washing machine with a balancer to counterbalance unbalanced load produced during rotation of a drum perform a ball distributing cycle of seating masses in a groove in the balancer before rotation of the drum possibly producing unbalance as in the spin-drying cycle begins to efficiently maintain balance of the drum, and a laundry untangling cycle of evenly distributing the laundry in the drum. Accordingly, vibration and noise may be reduced during the spin-drying cycle. In addition, in retrying the spin-drying, the ball distributing cycle is restricted based on the rate of rotation of the motor at the moment at which unbalance is sensed. Thereby, delay in cycle time in retrying the spin-drying cycle may be prevented. | 01-15-2015 |
20150068255 | BALANCER OF WASHING MACHINE - A balancer of a washing machine including a balancer housing mounted to a front surface of a drum and having an annular channel therein, a plurality of masses movably disposed along the channel, at least one magnet coupled to the balancer housing so as to restrict the masses from moving along the channel when a revolution per minute value of the drum is within a specific revolution per minute range, and at least one guide groove which is formed on an inner surface of the balancer housing and guides movement of the plural masses when the drum rotates. | 03-12-2015 |
