Abstract: A fan includes a housing, an impeller and a motor. The impeller includes a hub, a ring and a plurality of flat blades. The ring surrounds the hub without substantial contact therewith and is connected to the hub by at least one connecting arm. The flat blades are disposed on the ring and the active surface of each flat blade has an imaginary extending lines which is which is tangent to a rim of the hub.

Abstract: This invention relates to method(s) of fabricating electrodes of an external electrode fluorescence lamp (EEFL) for use in thin film transistor-liquid crystal display (TFT-LCD) applications. Also disclosed is a structure with electrodes for external electrode fluorescence lamps used in TFT-LCD backlight units.

Abstract: The invention relates to an oil-leak proof bearing system, and the system includes a bearing, an oil-leak proof cover and a rotor shaft. The center portion of the oil-leak proof cover defines a through hole, and the inner wall defining the through hole is provided with at least one first guiding groove thereon extended obliquely downward from the upper edge of the inner side face to force oil dispersed by the rotor shaft to flow back into the bearing system. The bottom surface of the oil-leak proof cover, contacting the bearing, is provided with second guiding grooves extending radially approximately from the center thereof. The capillarity of the second guiding grooves guides the oil dispersed by the rotor shaft to flow radially. The design of the first and second guiding grooves prevents the bearing system from leakage of lubricating oil, and provides a closed oil loop for operation.
