A surgical instrument and related methods are described. The surgical instrument includes a first jaw including a first structural jaw element and a first sealplate fixed to the first structural jaw element and a second jaw including a second structural jaw element and a second sealplate fixed to the second structural jaw element. The second structural jaw element is moveably coupled to the first structural jaw element to facilitate pinching tissue between the first and second sealplates. The first and second sealplates are configured to facilitate sealing tissue pinched therebetween. The first jaw further includes a metallized tie layer between the first sealplate and the first structural jaw element, wherein the first sealplate is fixed to the first structural jaw element via a metal to metal joint between the first sealplate and the metallized tie layer.

Shielding coatings are applied to polymer substrates for selective metallization of the substrates. The shielding coatings include a primer component and a hydrophobic top coat. The primer is first applied to the polymer substrate followed by application of the top coat component. The shielding coating is then selectively etched to form an outline of a desired current pattern. A catalyst is applied to the patterned polymer substrate followed by electroless metal plating in the etched portions. The portions of the polymer substrate which contain the shielding coating inhibit electroless metal plating. The primers contain five-membered heterocyclic nitrogen compounds and the top coat contains hydrophobic alky organic compounds.

A metal plating apparatus for plating metal with zinc is provided with a rotating device and a plurality of stirring devices. The rotating device has a driving assembly and a rotating assembly. The driving assembly has a driving gear. The rotating assembly is connected with and controlled by the driving assembly. The rotating assembly has a sustaining pillar. A rotating seat is mounted on the sustaining pillar and engaged with the driving gear. The stirring devices is mounted on the rotating seat radially and spaced from each other. The metal plating apparatus improves productivity through an automatic process which shifts locations of the stirring devices by the rotating device and plates metal with a cooperation of peripheral supporting apparatus, and improves working efficiency through decreasing occupied space and the number of operating personnel.

The present invention pertains to a multilayer tubular article, to processes for the manufacture of said multilayer tubular article and to uses of said multilayer tubular article in upstream applications for conveying hydrocarbons from a well to a floating off-shore unit via a bottom platform.

A web transport system for transporting a web of media along a web transport path in an in-track direction, including a liquid application system for applying a liquid to at least one surface of the web of media. An air skive is positioned along the web transport path downstream of the liquid application system, wherein the air skive directs one or more streams of air onto the web of media thereby removing at least some of the liquid that is being carried along with the web of media. A vapor source adds a vapor into the one or more streams of air provided by the air skive before the one or more streams of air are directed onto the web of media.

A coating agent for forming an oxide film; a method for producing an oxide film; and a method for producing a metal-plated structure, where the stability of the coating agent can be enhanced, and an oxide film which can be plated and has high adhesion to a substrate can be easily formed. The coating agent for forming an oxide film is a liquid coating agent, essentially contains titanium atoms, and optionally contains silicon atoms and copper atoms, wherein the ratio of the sum of the titanium atoms and copper atoms to the silicon atoms is 1:0-3:2. The method for producing an oxide film includes applying the coating agent to a substrate and heating to form an oxide film. The method for producing a metal-plated structure includes: a metal-film-forming step for forming a metal film on the oxide film; and a baking step for baking the metal film.

According to an embodiment of the present invention, a method for producing a duplicate of a nano-pattern texture of a surface of an object through electroforming using an imprint mold comprises selecting the object having the nano-pattern texture, disposing the selected object and pretreating a surface of the object by washing, drying and then forming a nano-thin film thereto to block transfer of impurities, metallizing a surface of the plastic mold through, e.g., vapor deposition, spraying, and wet silver mirror reaction, and performing a first electroforming of the surface of the plastic mold, and repeating to thus manufacture a plurality of metal module master molds.

A viscous liquid feed nozzle has a nozzle body having a thin and long hole with a front end serving as a feed port. The nozzle is used with a viscous liquid feed unit to feed a viscous liquid such as a viscous adhesive from the feed port. The nozzle has a lubricative plated layer at least on the inside and outside of the feed port. The lubricative plated layer is formed by electroless plating by immersing the nozzle in a plating tank containing a lubricative plating solution. A base end of the nozzle body may have a wide port. In this case, the lubricative plated layer is formed by immersing the nozzle body in the plating tank containing the lubricative plating solution so that the lubricative plating solution enters the wide port and by applying pressure or gravity to the lubricative plating solution in the wide port to pass the lubricative plating solution through the thin and long hole of the nozzle body and discharge the same from the feed port. The viscous liquid feed nozzle with the lubricative plated layer is capable of stably feeding a very small quantity of a viscous liquid.
