Embodiments of the invention provide a method of forming a chalcogenide material containing device, and particularly resistance variable memory elements. The clamp assembly includes of a pair of hinged jaws that are opened and closed by a pair of rams attached to the jaws and the frame members that make up the assembly. A nitrogen heterocycles in the membrane interact with acid in the electrolyte to form donor-receptor proton transport network, so as to keep the proton transport performance of the membrane. If no directional event is triggered within the second time period, enable the select event. Therefore, any workpieces can be fixed to the magnetic devices by magnetic attraction. A connector secures the catheter to the distal end of the blade.
