Abstract
A decompression path conductance factor calculation deviceobtains a cavity pressure change characteristic representing a pressure change characteristic of a cavity portionfrom an exhaust speed of a decompression device, a cavity conductance factor, an overflow conductance factor, a decompression path conductance factor, and respective volumes of inside spaces of a cavity portion, an overflow portion, and a decompression path, obtains a decompression path pressure change characteristic representing a pressure change characteristic of the decompression pathfrom the exhaust speed of the decompression device, the volume of the inside space of the decompression path, and the decompression path conductance factor, and obtains the decompression path conductance factor such that a difference between respective approximate curves representing the obtained cavity pressure change characteristic and the obtained decompression path pressure change characteristic becomes a threshold value or less.
