PROBLEM TO BE SOLVED: To provide a vacuum pump that can reduce vibrations transmitted to a pump base effectively and easily.SOLUTION: In a vacuum pump, a supporting mechanism 14 for elastically supporting an outer ring 8b of a grease-lubricated bearing 8 comprises supporting members 14A and 14B stacked in an axial direction of a shaft 10. The supporting members 14A and 14B comprise outside annular parts 141 and inside annular parts 142 formed so as to surround an axis J and arranged concentrically. In addition, the extending direction (tangential direction) of linear plate-like spring parts 143a and 143b provided in the supporting member 14A is different by 90° from that of linear plate-like spring parts 143a and 143b provided in the supporting member 14B. Thus, the outer ring 8b easily moves in a radial direction, and vibrations transmitted to the pump base can be reduced.

PROBLEM TO BE SOLVED: To provide a concentration calculation device, a concentration calculation method, and a concentration calculation program which allow calculation of a concentration of a target component in the middle of analysis.SOLUTION: Mass ratios of target components to reference components are stored per target component in a mass ratio storage unit 122. An area value in a graph showing a relation between intensity and time detected by a detector 5 is calculated by an area value calculation processing unit for a reference component identified by an identification processing unit 112. On the basis of the mass ratio stored in the mass ratio storage unit 122 in association with a target component identified by the identification processing unit 112 and the area value calculated by the area value calculation processing unit 113, a concentration of the target component is calculated by a concentration calculation processing unit 114. By using the mass ratio of the target component to the reference component, the concentration of the target component can be calculated even in the middle of analysis when the target component and the reference component are identified.

Abstract:
PROBLEM TO BE SOLVED: To provide a heat transfer mechanism that hardly causes stress in each member during heating or during cooling and hardly causes variation in temperature distribution in a heat sink, and to provide a thermal analysis device including the heat transfer mechanism.SOLUTION: A heat resistance section 52 is formed by forming an opening 51 in a heat transfer section 5 for transferring heat between a heat sink 2 and a cooling source 4 and by partially reducing the cross section. Since the heat resistance section 52 can be formed using a part of the heat transfer section 5, difference in linear expansion coefficient and temperature difference between members is inhibited from causing stress in each member during heating or during cooling. Nonuniformity hardly occurs in a junction state, so that variation in temperature distribution hardly occurs in the heat sink.

Abstract:
PROBLEM TO BE SOLVED: To provide a gas passage switching device, a gas passage switching method, and a gas passage switching program which allow a target component to be accurately separated from a first passage into a second passage.SOLUTION: If a time RT when a preliminarily determined reference component (peak P2) is detected by a detection part is shifted from a reference time associated with the reference component by a prescribed time ΔRT, switching timings T1 and T2 of a switching part for guiding a target component (peak P1) from a first passage into a second passage are shifted in real time. Since the time when the target component will pass a branch part is shifted if the time RT when the reference component is detected is shifted, the switching timings T1 and T2 of the switching part are shifted by times ΔT1 and ΔT2 corresponding to the prescribed time ΔRT, so that the target component can be accurately separated from the first passage into the second passage.

PROBLEM TO BE SOLVED: To provide an analyzer capable of correctly analyzing an error at a low cost.SOLUTION: Error information is stored in an error information storage unit 3 in association with not only a timer value from a timer unit 11 but also updated identification information stored in an identification information storage unit 2. After a power supply switch 4 is changed from an off state to an on state, identification information associated with error information stored last in the error information storage unit 3 is read out and updated in predetermined order, and the updated identification information is stored in the identification information storage unit 2. When an error detection unit 12 detects an error, error information is stored in the error information storage unit 3 in association with a timer value from the timer unit 11 at that time and the updated identification information stored in the identification information storage unit 2. This enables correct error analysis based on the identification information at a low cost.
