A microwave-excited plasma processing apparatus shows a wide pressure range and a wide applicable electric power range for normal electric discharges as a result of using slits cut through a rectangular waveguide and having a profile that allows the electric field and the magnetic field of microwave to be formed uniformly right below the microwave introducing window below an microwave antenna. The closure components couple the left and right base panels to each other laterally and have left and right ends coupled to the respective base panels. The one piece shuttle mechanism includes a thrust bushing and one or more concentrically formed spring arms that are adapted to provide axial loading in the direction of an electrical connector shell when the basketball adapter assembly is assembled to an electrical connector. The device further includes at least one sensor operably coupled with the body portion. Areas of specific focus in this document include delegation of duties between the internet server and the WebDAV tool, efficient management of a resource’s content-type, support for segregation of a namespace into separate virtual roots, and determinations of whether to invoke certain processing extensions to handle requests for a given HTTP verb. A process for producing such a metal-made seamless pipe is also provided.
