| 20100116463 | SELF-CLEANING DEVICE OF FILTERING NET AND AIR CONDITIONER HAVING IT - A self-cleaning device of a filtering net is disposed in a wall-hanging type air conditioner and includes a filtering net with an upper filtering net and a front filtering net, which is disposed outside a heat exchanger and is used for absorbing dust in the air passing through the heat exchanger. A dust sweeping assembly with a detachable brush is disposed outside the filtering net, and is used for sweeping the dust adhered on the filtering net. A drive device with a drive motor and a transmission mechanism is used for driving the dust sweeping assembly to slide on the filtering net to sweep off the dust. A dust box is used for collecting the dust and is detachably disposed in the air conditioner to clear up the dust in the box. A dust exchanging device is disposed on the left or right side of the filtering net, and is used for transferring the dust swept out by the sweeping assembly into the dust box. The self-cleaning device of a filtering net of an air conditioner can clean up the dust on the filtering net in a short time with good clearance effects, and less noise. The structure of the device has high reliability and durability, and is simple. | 05-13-2010 |

| 20100039576 | LIQUID CRYSTAL DISPLAY - A liquid crystal display with better visibility and transmittance. The liquid crystal display includes a first plate having a first field-generating electrode, disposed in a pixel area on an insulating substrate, comprising a plurality of sub-electrodes which are separated from each other by a predetermined distance and arranged parallel to each other, and a connecting electrode electrically connecting the sub-electrodes. An alignment film that is rubbed in a first direction covers a first field-generating electrode and an alignment film that is rubbed in a second direction covers a second field-generating electrode to achieve a predetermined orientation of the liquid crystals when no field is applied and more uniform rotation of the liquid crystal molecules when a field is applied. | 02-18-2010 |

| 20080296261 | APPARATUS AND METHODS FOR IMPROVING TREATMENT UNIFORMITY IN A PLASMA PROCESS - Apparatus and methods for improving treatment uniformity in a plasma process. The sacrificial body, which is extends about an outer peripheral edge of the workpiece during plasma processing, is composed of a plasma-removable material. The sacrificial body may include multiple sections that are arranged to define a circular geometrical shape. The sacrificial body functions to increase the effective outer diameter of the workpiece, which operates to alleviate detrimental edge effects intrinsic to plasma processing by effectively reducing the etch rate near the outer peripheral edge of the workpiece. | 12-04-2008 |
