A bellows design collapsible polymeric storage tube. The NC machine tool includes deflection detecting means provided on a base within a machining area, and run-out diagnosing means for conducting a diagnosis on the run-out of the spindle by calculating the amount of the run-out of the spindle on the basis of a deflection detected by the deflection detecting means and comparing the calculated run-out amount with a predetermined tolerance. A delay is introduced into the first portion of pulses and the first portion of pulses is directed onto a thin film specimen along a line. The first member is a ribbed member in a first orientation and the second member is a ribbed member, identical to the first ribbed member, attached to the first ribbed member in a second orientation inverted from the first orientation. To make the connection, it is then necessary only to heat the whole junction with an external heat source until the solder in the solder deposits melts and fills the gaps between the inner wall of this section of the sleeve and the outer wall of the waveguide.
