Abstract: The present invention relates to a system for separating and recycling a perfluorinated or perfluor compound, and more particularly, to a system for separating and recycling a perfluorinated compound, which is developed to prevent damage of separation membranes and degradation of the separation efficiency of through the application of a constant pressure to respective separation membranes when the perfluoro compound passes through a plurality of separation membranes in a process of effectively separating, removing and recycling the perfluoro compound including sulfur hexafluoride primarily generated in a semiconductor manufacturing process.

Abstract: A scanning probe microscope has a cantilever with a probe facing a sample and a measurement section for measuring a physical quantity occurring between the probe and the sample when the probe scans a surface of the sample, holding the physical quantity constant to measure the surface of the sample. The above microscope further has a probe tilt mechanism, an optical microscope etc. for detecting a position of the probe when the probe is tilted, and a control section for setting the probe in a first tilt posture and second tilt posture, measuring a surface of the sample by the measurement section at each tilt posture, detecting the position of the probe at least at the second tilt posture by the optical microscope etc., and making a measurement location at the second tilt posture match with a measurement location at the first tilt posture for measurement.

Abstract: This scanning probe microscope is provided with a cantilever with a probe tip facing a sample, a Z fine movement section for changing a distance between the sample and the probe tip, a XY scanning control section for providing relative displacement toward a sample surface between the sample and the probe tip, a displacement detecting means for detecting displacement arising in the cantilever, and a Z direction control section. In the configuration, when generating deformation in the cantilever due to a physical amount between the probe tip and the sample, the displacement detecting means detects the displacement of the cantilever, and the displacement of the cantilever is controlled to be a predetermined constant value. The scanning probe microscope further has a two frequency signals generating section for providing signals used to cause the probe tip to be moved in height direction by two frequencies to the Z fine movement section.

Abstract: An ultrasonic inspection apparatus obtains information on the interface of a sample as digital waveform data for any “unit measurement range” and is provided with at least two data memories and controlled by a scan state monitoring signal showing the scan state of a unit measurement range belonging to a first group or a unit measurement range belonging to a second group. A comparator-register/memory-control-circuit outputs the scan state monitoring signal to the two data memories. The operating states of the two data memories being controlled by the scan state monitoring signal to alternate between writing of digital waveform data and readout of digital waveform data.
