    摘要： A multistage positive-displacement vacuum pump which is preferably used in the fabrication of semiconductor devices and can be operated from atmospheric pressure. The vacuum pump comprises a pump casing, a pump assembly housed in the pump casing and comprising a pair of pump rotors rotatable in synchronism with each other and arranged in multiple stages, and an intermediate pressure chamber provided between a preceding stage and a subsequent stage in the pump casing. The shaft portions of the pump rotors located between the preceding and subsequent stages are located in the intermediate pressure chamber.

    摘要： A vacuum evacuation device 2 of the invention comprises a vacuum pump 4,5 for exhausting a gas G2 in a process chamber 21 into which a process gas G1 is introduced and in which a process reaction is performed, to form a vacuum in said process chamber 21; and a control means 6 for performing a first control that regulates the rotational speed of said vacuum pump 4,5 such that a pressure condition in said process chamber 21 reaches a pressure condition suitable for said process reaction during said process reaction, wherein said control means 6 calculates a specified rotational speed for said vacuum pump 4,5 based on process information related to said process reaction, and performs a second control that brings said vacuum pump 4,5 to said specified rotational speed before said first control. The vacuum evacuation device 2 is capable of bringing the pressure in a process chamber 21 to the target pressure in a short period without a vacuum pump 4,5 being overloaded, regardless of the process reaction condition.

    摘要： A flowmeter can measure a small flow rate of fluid with high measurement precision, can be made small-sized, can deal with a variety of types of chemicals, and can be produced easily at a low cost. The flowmeter includes: a casing having an enlarged portion and being disposed vertically; and a float enclosed in the enlarged portion of the casing and at least partly having a detection surface. The float is to be pushed up by a fluid flowing from below into the casing and flowing upwardly in the casing. The flowmeter also includes at least one displacement sensor, disposed outside the enlarged portion of the casing, for detecting an axial displacement of the float by magnetizing the detection surface of the float.

    摘要： A rotor has an interior free from invasion of water and is resistant to deformation from applied stresses normally encountered during the operation of a vacuum pump. The rotor comprises a rotor shell formed to conform to an outline of lobes and side-plates for covering transverse ends of the rotor shell. A rotation shaft is secured to the side-plates. A hollow section is formed by the rotor shell and the side-plates which is under a vacuum environment.
