摘要:
A device for forming at an ambient atmospheric pressure a gaseous plasma comprising active species for treatment of a treatment region. The device comprises a plasma cell for forming the gaseous plasma for treating the treatment region. The plasma cell comprises an inlet for receiving gas from a source and an outlet for discharging active species generated in the cell. A dielectric substrate made of a polyimide encloses the flow path for gas conveyed from the inlet to the outlet and an electrode is formed on the dielectric substrate for energising gas along the flow path to form the active species. A protective coating or lining is located on an inner surface of the dielectric substrate for resisting reaction of the active species generated in the plasma cell with the material of the dielectric substrate.

Embodiments of the subject invention are directed to methods and apparatus for inducing fluid flow in a wind tunnel using one or more plasma actuators. In an embodiment, a wind tunnel is provided having a flow passage. A pair of electrodes is positioned on at least one surface of the flow passage, and a voltage potential is applied across the pair of electrodes producing a plasma discharge in the flow passage. In an embodiment, the pair of electrodes is positioned on the at least one surface of the flow passage such that when the plasma discharge is produced an electrohydrodynamic (EHD) body force is generated that induces flow of a fluid in the flow passage.

The present invention relates to a plasma generating device, a method of cleaning a panel, and a method of manufacturing a display panel using the same. In the present invention, a pair of dielectric plates 52 and 52′ are detachably installed to a nozzle head 50. To this end, an upper end of the dielectric plate 52 or 52′ is inserted into a seating slit 49 formed in a lower portion of a chamber housing 46, and a lower end of the dielectric plate 52 or 52′ is securely placed on and fixed to a stepped portion 59 formed in a lower end of an electrode cover 58. Further, in order to maintain a gap 53h between the dielectric plates 52 and 52′, spacers 64 are inserted in both ends of the gap 53h. According to the present invention so configured, uniform plasma can be generated since the gap between the dielectric plates can be kept constant. Further, the dielectric plates can be easily exchanged and maintained.
