A low profile explosion proof by containment enclosure includes a base wall having first and second edge sections that are joined with third and fourth edge sections to define a substantially planar surface. The stabilization part is longitudinally subdivided into a first portion located beside the bodywork part, and a second portion located remote from the bodywork part. A memory cell is selected in a selected subarray of a selected memory block, and a bit line of the selected memory cell is coupled to a corresponding local data line. The carrier fluid may be directed toward the substrate as the resist stripper is being applied thereto or following application of the resist stripper. The cross-sectional area of the lead pass bar helps to produce a substantially continuous threaded rebar product without longitudinal ribs using standard rebar manufacturing tooling and equipment. The link pin exchanging device comprises an actuator for moving the link pin so that the link pin disengages from the link mechanism, and a reaction force receiving member for receiving a reaction force that acts on the actuator, independent from the wall surface of the rotor hub that intersects with the operating direction of the actuator.
