An object of the present invention is to provide a method for manufacturing a multi-stage compression type rotary compressor which can avoid the replacement of parts to be used as much as possible to reduce costs and also which enables easily setting an appropriate displacement volume ratio while preventing the compressor from being increased in size. The moving disc is moveable in response to a pressure in the pressure chamber to cause contact between a moveable contact and a fixed contact. In integrated circuit fabrication, a wafer is subjected to wafer fabrication processes to produce a number of individual layers on a semiconductor substrate. A retention mechanism engages the septum and maintains the distal segment of the guide catheter extending into the one of the first heart chamber and the second heart chamber . The other operation, the push operation or the pull operation, is performed with a current output from the current mirror circuit. Both ends of the fusible body 5 are mechanically connected to the end faces 8.
