Abstract: A scanning probe microscope provided with a cantilever 21 having a probe 20 facing a sample 12, a measurement unit 24 measuring a physical quantity occurring between the probe and sample, and movement mechanisms 11, 29 changing a positional relationship between the probe and sample to cause a scanning operation and making the probe scan the surface of the sample by the movement mechanism and measure the surface of the sample by the measurement unit.

Abstract: A probe is made by attaching a carbon nanotube 12 to a mounting base end 13, which eliminates the effects of a carbon contamination film, to increase the bonding strength, increase the conductivity of the probe, and strengthen the bonding performance thereof by coating the entire circumference of the nanotube and the base with a coating film, rather than coating just one side. The work of mounting the carbon nanotube and mounting base end are performed under observation by a microscope. Further, the carbon contamination film 14 formed by an electron microscope is stripped off at a stage before bonding by the coating film.

Abstract: This probe control method is applied to the scanning probe microscope having a probe section with a probe pointed at a sample, a detection section for detecting physical quantity between the sample and the probe, a measurement section for measuring the surface of the sample to obtain the surface information on the basis of the physical quantity when scanning the sample surface by the probe, and a movement mechanism with at least two degree of freedom. The probe control method has steps of moving the probe in a scanning direction different from the contact direction while making the probe come into contact with the sample surface, detecting the torsional state of the probe during the movement of the probe, and adjusting either or both of the rate in the scanning direction and the force in the contact direction on the basis of the detected value obtained by the detection step.

Abstract: The probe tip movement control method of the scanning probe microscope is used for a scanning probe microscope provided with a cantilever 21 having a probe tip 20 facing a sample 12. The atomic force occurring between the probe tip and sample is measured when the probe tip scans the surface of the sample. X-, Y-, and Z-fine movement mechanisms 23, 29, and 30 are used to relatively change the positions of the probe tip and sample. It is possible to maintain a high measurement accuracy and enable scan movement of a probe tip on a sample surface by simple control when measuring a part having a gradient in measurement of an uneven shape on a sample surface.

Abstract: An ultrasonic inspection and imaging instrument is characterized by storing reduced image examples (images by means of reduced image display data obtained by scaling down picture display data) of an ultrasonic measurement picture beforehand, together with measurement conditions at the time the measurement picture is obtained prior to a scale-down imaging process. When the measurement is started or the measurement conditions are otherwise changed, the measurement conditions are set as those obtained from the measurement picture prior to the scale-down processing with one of the reduced image examples thus selected as an index while a list of image examples is indicated on a display and read from a memory unit for ultrasonic measuring purposes. When a reduced image example or what is similar to the example desired by an operator is selected, proper measurement conditions are automatically set in the ultrasonic inspection and imaging instrument.

Abstract: An ultrasonic inspection and imaging instrument scans an object under examination, the object having an inspection plane at a predetermined depth, in the direction slanted to the depth (slant scanning), in such a way as to cause rectilinear scanning as viewed from the plane. Measured data on a peak value corresponding to each measurement point obtained from the slant scanning are displayed in the form of a picture on the screen of a display relative to each measurement point. The image displayed on the picturee at that time is most clearly demonstrated, provided an image portion in the vicinity of a test portion corresponding to a test surface is brought into focus in the depth direction.
