An apparatus for plasma treating a substrate comprises a high voltage source of frequency 3kHz to 30kHz connected to at least one needle electrode (11) positioned within a channel (16) inside a dielectric housing (14) having an inlet for process gas and an outlet. The channel (16) has an entry (16a) which forms the said inlet for process gas and an exit (16e) into the dielectric housing arranged so that process gas flows from the inlet through the channel (16) past the electrode (11) to the outlet of the dielectric housing. The apparatus includes means for introducing an atomised surface treatment agent in the dielectric housing, and support means (27, 28) for the substrate (25) adjacent to the outlet of the dielectric housing. The needle electrode (11) extends from the channel entry (16a) to a tip (11t) close to the exit (16e) of the channel and projects outwardly from the channel (16) so that the tip (11t) of the needle electrode is positioned in the dielectric housing close to the exit (16e) of the channel at a distance outside the channel of at least 0.5mm up to 5 times the hydraulic diameter of the channel. The channel (16) has a ratio of length to hydraulic diameter greater than 10:1.

A plasma CVD apparatus according to the present invention is provided with: a vacuum chamber 4; a pair of deposition rollers 2, 2, each of which is disposed in the vacuum chamber 4, and has a substrate W wound thereon, the substrate on which a coating is deposited; and magnetic field generating sections 8, 15, each of which forms a deposition area where the coating is deposited on the substrate W wound on each deposition roller 2 by generating a magnetic field that generates plasma on the surface of each deposition roller 2. The pair of deposition rollers 2, 2 are composed of a first deposition roller 2, and a second deposition roller 2, which is disposed at an interval from the first deposition roller 2 such that the shaft core of the second deposition roller is parallel to that of the first deposition roller 2. The magnetic field generating sections 8, 15 are disposed such that a first deposition area 19, as the deposition area, is formed in a space 3 between the pair of deposition rollers 2, 2, and that a second deposition area 20 is formed in a region adjacent to the surface of the deposition roller 2 and other than the space 3.

A coat forming apparatus 100 includes a droplet supply unit 110 and an active species supply unit 120. The droplet supply unit 110 is adapted to spray or drop a droplet for coat forming toward an object 116. The active species supply unit 120 is adapted to supply an active species to be brought into contact with the droplet moving from the droplet supply unit 110 toward the object 116. The coating is formed on a surface of the object 116 by the droplet that has been brought into contact with the active species.

摘要:
Elastomeric components, such as a shoe outsole, are treated with a plasma application to clean and activate the elastomeric component. The application of plasma is controlled to achieve a sufficient surface composition change to enhance adhesion characteristics while not adversely physically deforming the elastomeric component. The plasma treatment is applied to increase carbonyl functional group concentrations within an altered region of the elastomeric component to within at least a range of 2% - 15% of carbon atomic percentage composition. The cleaning and activation is controlled, in part, by ensuring a defined height offset range is maintained between the elastomeric component and the plasma source by a generated tool path. The elastomeric component may then be adhered, with an adhesive, to another component.

The invention relates to an apparatus (1) for producing a plasma (P), comprising a control circuit (3) which is electrically connected to a piezoelectric transformer in order to excite the piezoelectric transformer (5). The invention further relates to a hand-held device (100) that uses the apparatus (1). The piezoelectric transformer (5) is constructed of several layers (S1, S2,..., SN). The control circuit (3) is implemented on a circuit board (7), and the piezoelectric transformer (5) is held over the circuit board (7) by means of a region (6B) of a first end (6). A high voltage is applied to a second free end (8) of the piezoelectric transformer (5), wherein the plasma (P) is produced at atmospheric pressure.
