| 20100125267 | Plasma Gun for Bio/Medical Treatment - There is disclosed a plasma gun for bio/medical treatment using atmospheric plasma. The disclosed plasma gun comprises a housing having an elongate chamber provided therein, the chamber having an end at which a nozzle for spraying plasma is positioned; a gas supply unit for supplying a reaction gas to the chamber; and a plasma discharge unit formed with an elongate cavity communicating with the nozzle, the plasma discharge unit including first and second electrodes and a dielectric or insulating barrier material for plasma ignition in the elongate cavity. | 05-20-2010 |
| 20090200267 | INJECTION TYPE PLASMA TREATMENT APPARATUS AND METHOD - The present invention relates to an injection type plasma treatment apparatus. An object of the present invention is to provide an injection type plasma treatment apparatus capable of treating work pieces with a variety of areas, sizes and shapes without damages due to micro arc streamer by using a method of injecting plasma, which is generated through dielectric barrier discharge (DBD) under the normal pressure condition, toward the work pieces. | 08-13-2009 |
| 20080308121 | Portable Die Cleaning Apparatus and Method Thereof - A portable die cleaning apparatus and method are provided The apparatus is capable of performing a plasma cleaning process for a surface of a die using plasma discharge generated in a reaction chamber that is defined on the die, without separating the die. The portable die cleaning apparatus includes a frame with an open lower face to define a reaction chamber facing the surface of the die between the surface of the die and the frame itself when the frame is seated on the die and an active electrode that is placed at a position opposite to the die in a state where the die is electrically grounded, and receives electric power from an external power supply to generate plasma in the reaction chamber. | 12-18-2008 |
