A recording medium having recorded thereon information of images coded by performing motion compensation is provided to obtain high quality images without error accumulation. The width of the groove on the primary pulley is adjusted by the oil pressure in the primary hydraulic chamber in the primary cylinder, the width of the groove on the secondary pulley is adjusted by the oil pressure in the secondary hydraulic chamber in the secondary cylinder. The CMP processes are carried by using acid slurry having a high polishing selectivity with respect to the nitride layer, so a step difference between the cell region and the peripheral region is removed, thereby simplifying the semiconductor manufacturing process and removing a dishing phenomenon. The method concludes with the step of forming metal silicide regions on the gate electrode structures and on the sourcedrain regions. The invention equally relates to a corresponding communications system, network element and module for a network element. In one embodiment, attachment stresses of an electronic module assembly are isolated from the sense surface by attaching the assembly to a support ring end wall welded to a portion of the first body removed from the sense surface and providing a control gap between the support ring and the sense surface.
