    摘要： A plastic tube extruded from an extruder is conveyed through a plasma treatment apparatus. The plasma treatment apparatus is equipped with a tubular electrode body having a high-voltage side electrode and a grounded-side electrode disposed on a tubular insulator and a high frequency electric power source connected to the electrodes. When the plastic tube is conveyed through the electrode body with one end of the tube open to the atmosphere, a mixture of a glow discharge-stabilizing gas and a treating gas is fed into the other end of the tube and an alternating-current high-voltage is applied to generate a plasma region at a pressure near to atmospheric pressure in which the tube is treated with a glow discharge plasma. This method allows an interior and/or exterior surface of a plastic tube designed to convey a medical fluid to be continuously treated by a glow discharge plasma at atmospheric pressure to form an anti-thrombotic and blood-compatible film on the surface treated. The resulting surface-treated medical material can be produced at a comparatively low cost and maintains its original bulk material properties.

    摘要： A plasma reaction method is conducted at atmospheric pressure and is used to treat a surface of a substrate with a reactive plasma. The reaction method involves introducing a mixture of helium and a reactant (monomer) gas into a reaction vessel having upper and lower electrodes. In a preferred embodiment the upper electrode is provided with grooves for diffusing the plasma uniformly over the surface of the electrode. The helium and reactant gas mixture is excited at atmospheric pressure to produce a stable glow discharge plasma which reacts with the surface of the substrate. The preferred gas mixture has helium present at greater than 90% and uses ethylene or tetrafluoromethane as a reactant component.

    摘要： Generation and stabilization of glow plasma by discharge under atmospheric pressure are monitored by detection of the number of electric current pulses per one-half cycle of an alternating voltage applied to a discharge device. Alternately, or in addition, a Lissajous figure is generated showing a correlation between the applied alternating voltage and a current flow in the discharge device, and a discharge state is discriminated according to the Lissajous figure. Accurate, quick and simple monitoring of atmospheric pressure glow discharge plasma and the control thereof are thus made possible.

    摘要： A surface treatment process for improving surface properties of a timber as to wetness by exposing the timber to a plasma mixture of an inert gas and a reactive gas at a near atmospheric pressure. Prior to being exposed to the plasma mixture, the timber is treated to reduce a moisture content below a fiber saturation point of the timber so as to eliminate free moisture from the fibers of the timber which would otherwise lead to unstable plasma and therefore detract an uniform improvement over substantially the entire surface expected at the subsequent exposure to the plasma mixture. Thus, the plasma treatment can be effected in the absence of the free moisture to obtain a desired surface improvement uniformly across the surface of the timber, which gives an enhanced practicability of improving the surface properties of the timber, in addition to that the plasma mixture is generated at near the atmospheric pressures readily available without requiring substantial vacuum generating equipments.
