20130118212 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a main body defining an outer appearance, a tub disposed within the main body, a main drum rotatably mounted in the tub, a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum, an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft that is rotatable outside the stator, and an inner rotor connected to the outer shaft that is rotatable inside the stator, wherein the driving motor independently drives the main drum and the sub drum. | 05-16-2013 |
20130118213 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. Stator slots, which are fixedly-installed as a coil are wound on stator teeth. The outer rotor and the inner rotor include rotor teeth, a permanent magnet and a bushing, spaced from an inner circumference of the stator and rotates centering around a rotor shaft by magnetic force. The rotor teeth includes a teeth extension portion extending from a side end of an outer circumference of the rotor teeth in a circumferential direction, a cut recess cut in a concaved manner from the outer circumference of the rotor teeth toward the center of the rotor shaft, and an insertion recess cut in a concaved manner in a radial direction from an inner circumference of the rotor teeth. | 05-16-2013 |
20130118214 | WASHING MACHINE TO PRODUCE THREE-DIMENSIONAL MOTION - A washing machine includes a main body defining an outer appearance, a tub disposed within the main body, a main drum rotatably mounted in the tub, and a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum. The washing machine includes an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft and rotatable outside the stator, and an inner rotor connected to the outer shaft and rotatable inside the stator. The washing machine also includes a spring washer inserted into a connection part of the outer shaft and the inner rotor that attenuates vibrations of the outer shaft to prevent noise and to prevent separation of the outer shaft due to the vibrations. | 05-16-2013 |
20130266067 | METHOD AND DEVICE FOR ENCODING/DECODING IMAGE BY INTER PREDICTION USING RANDOM BLOCK - A video encoding apparatus, a video decoding apparatus and method of encoding and decoding one or more images using various shapes of blocks. The video encoding apparatus is configured to determine a partition form, among candidate partition forms, for partitioning a current block into one or more partition blocks; generate one or more predicted blocks by performing a motion compensation with a scale factor applied to the one or more partition blocks; generate a residual block by subtracting the predicted blocks from the corresponding one or more partition blocks; generate at least one transform block by transforming the residual block; generate at least one quantized transform block by quantizing the at least one transform block; and encode the at least one quantized transform block, information on the determined partition form, and the scale factor into a bitstream. | 10-10-2013 |
20130315302 | METHOD AND APPARATUS FOR CODING/DECODING IMAGE - The present disclosure provides an apparatus for encoding a video including: a prediction unit to generate a predicted block of a current block; a subtraction unit to generate a residual block by subtracting the predicted block from the current block; a transformer to transform the residual block into a frequency transform block by performing different transform methods on different transform units; a quantization unit to quantize the frequency transform block to generate a quantized frequency transform block; and a bitstream generator to encode the quantized frequency transform block into a bitstream. | 11-28-2013 |
20140366283 | Washing Machine to Produce Three-Dimensional Motion - A washing machine includes a main body defining an outer appearance, a tub disposed within the main body, a main drum rotatably mounted in the tub, a sub drum mounted in the main drum to be relatively rotatable with respect to the main drum, an outer shaft for rotating the main drum, an inner shaft for rotating the sub drum, being disposed inside the outer shaft, and a driving motor having a stator, an outer rotor connected to the inner shaft that is rotatable outside the stator, and an inner rotor connected to the outer shaft that is rotatable inside the stator, wherein the driving motor independently drives the main drum and the sub drum. | 12-18-2014 |
20150020554 | LAUNDRY TREATING APPARATUS - A laundry treating apparatus may include a tub, a drum, a driving system including a bearing housing and a driving motor for rotating a rotation shaft of the drum, supporting devices extending between a lower surface of the cabinet and the bearing housing, and a plurality of dampers installed between the supporting devices and the lower surface of the cabinet. The plurality of dampers may include first dampers extending inward from a front portion of the supporting devices toward the lower surface of the cabinet, and second dampers extending downward from the supporting devices toward the rear side of the cabinet. This arrangement may prevent vibration generated during rotation of the drum from being transferred to the tub, and thus an additional component for reducing vibration of the tub may not be required. Thus, the laundry treating apparatus may have a larger capacity within a fixed size of cabinet. | 01-22-2015 |
