Abstract: A plasma display panel (PDP) is provided. The PDP includes: a first substrate and a second substrate facing each other; a plurality of first barrier ribs on the second substrate defining a plurality of cells between the first substrate and the second substrate; pairs of scan electrodes and sustain electrodes on the first substrate; a plurality of second barrier ribs each dividing a corresponding cell of the cells into a primary discharge space and an auxiliary discharge space; a plurality of address electrodes on the second substrate. A portion of an address electrode among the address electrodes corresponding to the auxiliary discharge space is wider than other portions of the address electrode, thereby providing an improved addressing discharge.

Abstract: Apparatus for and a method of cleaning or processing a wafer anticipates a malfunction of a pump and avoids an abrupt shutting down of the pump during the cleaning or processing of the wafer. The apparatus includes a tank vessel containing a liquid used in the cleaning or processing of the wafer, a pump that pumps the liquid chemical from the vessel, a filter that filters impurities contained in the liquid pumped by the pump, a heater that heats the filtered liquid to a predetermined temperature and supplies the heated liquid back into the tank vessel, and a pump malfunction anticipation unit that operates at the same time as the pump. The pump malfunction anticipation unit calculates the flow rate of the liquid pumped by the pump using a program, and based on the flow rate anticipates when it is time to replace the pump.

Abstract: A user interface providing method and apparatus for a mobile terminal is disclosed. A managing area and a touch action area are set on a touch screen. A desired data file in the managing area is dragged and dropped into the touch action area, thereby playing the data file. The user can play a particular data file through simple drag and drop actions. As a result, the user can use a desired function of the mobile terminal in an intuitive manner.

Abstract: Disclosed is an easy dyeable polyester fiber. Consisting of 60-95 mol % of polyethylene terephthalate and 5-40 mol % of polytrimethylene terephthalate, the polyester fiber of the present invention is prepared through copolymerization or through the ester interchange in such a way that it ranges, in melting point from 230° C. to 250° C., in birefringence from 100 to 190×10−3, and in boil-water shrinkage, from 8 to 25. Using disperse dyes, the polyester fiber can be dyed in deep shades at as low as or lower than 100° C. under atmospheric pressure. Thus, the polyester fiber of the present invention is can be used in mixture with thermal resistance-insufficient fibers such as spandex without causing yellowing therein. Also, it does not allow spots in the dyeing to appear thereon upon after-treatment, and in addition shows good fastness to washing, water, sublimation and friction.
