摘要： PROBLEM TO BE SOLVED: To provide a ultraviolet microscope, with which damage to occur on an observation object because of the irradiation with ultraviolet rays can be reduced when inaging the observation object by using the ultraviolet microscope and to provide a control method therefor. SOLUTION: In the search stage of an observation position, an ND(neutral density) filter 12 is inserted on the optical path of DUV(deep ultraviolet) laser beam, the quantity of that light is reduced to the prescribed quantity of light within an allowable value, and damage on the irradiated surface of a sample caused by the Koehler illumination of DUV laser light is reduced. At such a time, the frame rate of a CCD(charge coupled device) camera 16 is decelerated by a frame rate control part 21, the analog image signal of an image picked up by the CCD camera 16 is amplified by an amplifier circuit 19, and the luminance gradation of the image made into digital signal is shifted to the side of lighter gradation by a gradation shift processing circuit 20. Thus, the brightness and contrast of the picture displayed on a monitor 26 are increased and the reduction of picture quality with the reduction of the quantity of DUV laser beam is complemented.

摘要： PROBLEM TO BE SOLVED: To eliminate positional deviation caused between the first observed image and the second and succeeding observed images by repeatedly moving the angle position of a scanning mirror from a scanning start position to a scanning finish position at the time of laser scanning and stopping the angle position of the scanning mirror at the scanning finish position after finishing the laser scanning. SOLUTION: A computer (scanning control system) controls the driving of a galvano scanner driver (driving device). Then, the galvano scanner mirror is always stopped at the scanning finish position 42 when a scanning control signal is not inputted. When a scanning start instruction is inputted, operation (4) is started. In the operation (4), the galvano scanner mirror at the position 42 is moved to the scanning start position 41 at a stretch. An XY plane to be observed is scanned in operation (5). Thereafter, the scanning control signals for the operation (4) and (5) are repeated till finishing the scanning of the XY plane. When the finish of the scanning is instructed, the galvano scanner mirror is stopped at the position 42 after the operation (5).

摘要： PROBLEM TO BE SOLVED: To extract only a sample substance having arbitrary physical quantity out of sample substances contained in a sample liquid by an arrangement wherein a control means produces a control signal when a detector detects a mass of sample having a physical quantity being set by a physical quantity setting means. SOLUTION: When a mass of sample having an arbitrary physical quantity is extracted from a sample solution containing sample substances, a physical quantity setting section 8 sets the physical quantity of a mass of sample to be extracted. When a detector 7 detects a mass of sample having an arbitrary physical quantity being set at the setting section 8, a control section 9 produces a control signal. Based on the control signal, a solution feeding member 14 in an extraction unit 11 is moved to the position of a specific container, e.g. a container 10-1, among a plurality of containers 10-1,..., 10-n. Consequently, a sample solution containing a mass of sample having a set physical quantity being fed from the member 14 is extracted into a specific container.
