Abstract: An elastic roll includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate, and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.

Abstract: The present invention relates to a plasma electrode including: an electrode main body having a discharge surface on the outer circumference surface thereof, the interior of the electrode main body having a magnet disposed therein for forming a tunnel-shaped magnetic field on the discharge surface; and ground members which face at least a portion of the discharge surface with a gap therebetween and face each other so as to sandwich the electrode main body therebetween. The discharge surface surrounds the outer circumference of the electrode main body, either with or without a gap interposed therebetween.

Abstract: In order to provide an adhesion preventing plate for a vacuum film formation apparatus, the adhesion preventing plate being capable of suppressing the peel-off of an adhered film to an extremely low level regardless of a protection target member, the adhesion preventing plate is arranged so that the area of contact with the protection target member is reduced and a part other than the contact surface is thermally insulated.

Abstract: A web pressure welding method for pressure welding, with respect to a running web, a first belt-shaped annular body which contact surface rotates with running of at least one web, where an area pressure for pressure welding to the web side is applied on the contact surface of the first belt-shaped annular body.

Abstract: The invention aims to provide a magnetron electrode for plasma treatment that is free of significant abnormal electrical discharge and able to perform electrical discharge with long-term stability. A second electrode is provided only at a position outside the inner side surface of the outer magnetic pole of a first electrode or at a position where the magnetic flux density is low.

Abstract: Two rotating members placed to face each other and nipping a web such that only an end of the web provided with conductivity is pressed are provided, at least one of the rotating members serves as a feeding electrode, and these rotating members are rotated about the same velocity to a transportation velocity of the web.

Abstract: A treatment tank is used which has a non-contact type liquid sealing unit capable of controlling liquid leakage in non-contact with a web.
