A compound semiconductor is placed in a reaction vessel of which the inner gas is subjected to replacement with a low-vapor-pressure gas whose equilibrium vapor pressure at the melting point of the compound semiconductor is 1 atm or lower. The generic service management system comprises a registration scheme; a search-and-execution scheme; and a detection-and-replacement scheme, used for detecting and replacing the invalid service provider, such as a semiconductor equipment manager. A flow through rotor having end plates that facilitate mounting more than one rotor on a common axis with rotationally varied timing and sequence, such that power delivery is smooth. At this point, the UV adhesive looses its adhesion so the dies are held together by the tack tape. In response to at least one servo detection error signal of one of the two servo bands, an edge stress signal is set to the cartridge memory of the magnetic tape cartridge.
