In a method of fabricating a bellows by bulge forming, an annealing step is carried out during the bulge forming process of the bellows so that the capability of the material to elongate is recovered, and the workability of the bellows is improved in effect. In accordance with turning on of power supply to the system controller, the mechanical driving member is driven until the device enters a main-operation stand-by status, in parallel to start of an OS by the system controller. A site may include one or more groundwater extraction wells. The RS encoder adds the RS parity place holders such that the RS parity place holders are placed after the enhanced data within each interleaved enhanced data packet. The base plate supports and is disposed below the intumescent member for limiting the expansion of the intumescent member toward or into the second working environment.
