TL;DR: In this article, the authors proposed a plasma treatment device, having a discharge space 20 with pairing electrodes 11, 13 arranged for generating discharge, a voltage impression means 2 impressing voltage between the electrodes 11 and 13, and an action gas supply means 4 supplying action gas consisting of inert gas or a mixture gas of inert and reactive gas to the discharge space, and generating discharge plasma by exciting the action gas supplied to discharge space with the discharge generated by impressing a voltage by the voltage impression, is also provided with a periodic change imparting means 7 for periodically changing at least either

TL;DR: In this article, the problem of reducing the gas temperature of a plasma stream and reducing the power consumption was addressed by using a dielectric barrier discharge to change the air supplied from the air supply part into plasma gas.

TL;DR: In this paper, a plasma torch 11 has an anode 23 and a cathode 25 installed with a spacing in between, and a gas supply part is installed between the anode and the cathode to supply the air as an operating gas.

TL;DR: In this article, a voltage is applied to two first and second electrodes 35 and 36 arranged at the outer periphery of a conveying tube 27 with the conveying path 26 through which carrier gas 25 flows, thereby generating an electric field E1 in the convey path 26.
