The production method for producing an article, comprises the step of rotating a rotating member so as to machine a semi-finished product with a machining section included in the rotating member. in the presence of an ionic liquid catalyst to produce the base oil having a kinematic viscosity at 40\xb0 C. A standby adapter handled by the device driver is switched in place of the primary adapter in response to detecting the failure. A drive mechanism coupled to the strand guide actuates movement of the strand guide in a direction transverse to the movement direction of the substrate, thereby causing the elastic strands to be applied to the substrate along the predetermined non-linear path. The electronic component accommodating bores are filled with an insulating layer. A quick release device laterally mounted to an outer periphery of the outer tube.
