A low-level function which enforces logical partitioning establishes a set of virtual indicator lights for certain physical components, the virtual indicator lights being only data in memory, a separate set of virtual indicator lights corresponding to each respective partition. These pellets have mechanical properties that are substantially equivalent to non-conductive pellets of a thermoplastic resin containing same loading of long glass and provide conductivity that is substantially equivalent to articles obtained by blending two kinds of pellets, one pellet having a conductive filler and the other pellet one containing long glass fibers. The base material is processed by relatively moving the long chamber and a base material holding mechanism holding the base material inside the annular chamber in a direction perpendicular to the longitudinal direction of the plasma jetting port.
