摘要： In a sample height regulating method, an area including the observation point on the sample is scan-irradiated with a first charged particle beam to obtain a first secondary electron image including the observation point. An area including the observation point on the sample is then scan-irradiated with a second charged particle beam to obtain a second secondary electron image including the observation point. Thereafter, based on magnifications of the first secondary electron image and the second secondary electron image and a distance between the observation point in the first secondary electron image and the observation point in the second secondary electron image, a height of the sample required for focusing the first charged particle beam and the second charged particle beam on the observation point is calculated. A sample stage supporting the sample is then displaced so as to position the sample at the calculated sample height.

摘要： Techniques for specifying an observing or working position of a sample are provided. Digitized data of a sample is obtained and stored in a 1st storage device. A 1st display area displays an image of a portion containing a desired observing or working position of the digitized data stored in the 1st storage device. A 1st position that is indicated by a pointing device on the 1st display area is stored in a 2nd storage device. The sample is moved to an observing or working position for observation, and an observation image of the sample is stored in the 3rd storage device. A 2nd display area displays the observation image of the sample stored in the 3rd storage device. A position indicated on the 2nd display area and corresponding to the 1st position stored in the 2nd storage device is stored in a 4th storage device. A conversion function for converting a coordinate system of the 1st display area and the 2nd display area is calculated using the 1st position stored in the 2nd storage means and the position stored in the 4th storage device. A position indicated in one of the 1st and 2nd display areas and corresponding to another position indicated in the other of the 1st and 2nd display areas is calculated in accordance with the calculated conversion function.

摘要： A cross-section processing and observation method includes: forming a cross section in a sample by a focused ion beam through etching processing; obtaining a cross-section observation image through cross-section observation by the focused ion beam; and forming a new cross section by performing etching processing in a region including the cross section and obtaining a cross-section observation image of the new cross section. A surface observation image of a region including a mark on the sample and the cross section is obtained. A position of the mark is recognized in the surface observation image and etching processing is performed on the cross section by setting, in reference to the position of the mark, a focused ion beam irradiation region in which to form the new cross section. Cross-section processing and observation is thus enabled continuously and efficiently using a focused ion beam apparatus having no SEM apparatus.

摘要： A seal useful in sealing slide out rooms used in recreational vehicles. The seal may be used singularly or in pairs to straddle a wall through which the opening is located. A bulb is attached to the base in a cantilevered manner over the base. The bulb has an outer arcuate portion that is integrally joined to opposing sidewall portions. The sidewall portions extend into an inner wall that defines an enclosed space within the bulb portion. The bulb portion may also have a protrusion that can touch the base. A wiper extends from the base substantially co-linearly to the base and opposite the offsetting member. A locating leg extending from the base is movable between a first position and a second position. The first position has the locating leg perpendicular to the base and the second position places the locating leg parallel to the base.
