An integrated circuit device is disclosed. The pressure moves a piston and die to compress material to be formed into a part. Therefore, the permanent magnets can be firmly and easily fixed at the mover body. The relation analyzing unit analyzes the relation between the areas extracted by the area relation extracting unit. A pressure relief valve may also include a modified orifice shape to improve stability, to uniformly distribute the effective bandwidth over the valve operating range, and to provide a tunable default mode.
