    • The present invention prevents the clogging of an oil supply hole in a compressor due to foreign substances, such as sludge, and avoids performance degradation caused by leakage of discharged refrigerant. In a compressor that is configured to guide lubricating oil separated from the discharged refrigerant by an oil separator to a radial bearing 10 supporting a drive shaft 8, through a oil supply hole 29, a rotating member 30 that rotates together with the drive shaft 8 is provided adjacent to the radial bearing 10 on the drive shaft 8, and lubricating oil is supplied to the radial bearing 10 via a gap between the external surface of the rotating member 30 and the internal surface of a circular hole 31 that supports the rotating member 30. An oil transport groove 32, which alternately communicates with the outlet of the oil supply hole 29 and the inlet of a discharge hole 33 every time the rotating member 30 rotates once, is provided on the external surface of the rotating member 30, and the lubricating oil flowing in from the oil supply hole 29 is intermittently discharged into a drive chamber 7 via the groove 32 and the discharge hole 33.

    • A multistage piston compressor includes a case and a suction chamber and a discharge chamber provided in the case. A rotary shaft is supported in the case. A valve plate provided in the case includes suction ports and discharge ports. A plurality of bores are provided at predetermined intervals about the axis of the shaft. Pistons are housed in the bores and compress refrigerant by reciprocating in accordance with the rotation of the shaft. An intermediate chamber connects a discharge port with a suction port. The refrigerant is compressed in stages by passing through a plurality of bores via the intermediate chamber. Compression chambers are defined between the pistons and the valve plate. A communication passage is provided for setting the pressures acting on the rear faces of the pistons to an intermediate pressure between the suction pressure and the discharge pressure.

    • The present invention provides a technique for eliminating the effect of the thermal drift and other variances and to improve the observing or manipulating accuracy of a scanning probe microscope or atom manipulator by using the technique to correct the aforementioned change in the relative position of the probe and the sample due to heat or other factors during the observation or manipulation. To obtain an image of the sample surface at the atomic level or perform a certain manipulation on an atom on the sample surface, the present invention can be applied to a probe position control method for controlling the relative position of the probe and the sample while measuring an interaction between the objective atom on the sample surface and the tip of the probe. In the present method, the relative position of the probe and the sample are changed while the probe is oscillated relative to the sample in two directions parallel to the sample surface at frequencies of f1 and f2 (S1a). Meanwhile, a point (or characteristic point) where the frequencies f1 and f2 disappear from the measured value of the interaction working in the direction perpendicular to the sample surface is detected (S1b). Then, the relative movement of the probe and the sample is controlled so that the measurement value thereby detected is maintained (i.e. the characteristic point is tracked; S1c), and the speed of the aforementioned relative movement is determined (S1d). Subsequently, the relative position control is corrected using the detected speed (S2).
