An approach processing part (104) determines a speed reduction position on the basis of the first information and the second information. The approach processing part (104) controls a displacement mechanism so that an approach speed changes from high speed to low speed at the speed reduction position.
Provided is a technology for identifying the type of a correction according to the state of the surface of a sample, an image of which has been generated on the basis of the measurement using a scanning probe microscope An image processing method according to the present invention comprises a step (SA1) for generating a corrected image by performing a first correction on a target image. The first correction includes extracting, from the target image, a plurality of pixels on a straight line along a prescribed direction on a prescribed plane and correcting the height of the target image on the basis of the luminance of each of the pixels extracted. The image processing method further comprises: a step (SA3) for generating a histogram of the pixel values in the corrected image; and a step (SA4) for using the histogram to determine whether or not a second correction, which is different from the first correction, is necessary on the target image.
An ultraviolet ray emitter includes an inner tube, an outer tube arranged around the inner tube, the outer tube defining between the outer tube and the inner tube, a discharge space where discharge gas is sealed, a pair of electrodes that causes discharge in the discharge space, and an auxiliary light source that assists excitation of discharge gas by emitting light to discharge gas from the outside of the outer tube. The outer tube is less likely to allow passage therethrough of ultraviolet light generated by excitation of discharge gas than the inner tube but allows passage therethrough of light having a wavelength emitted from the auxiliary light source.
A sampling needle (21) is inserted into a sample container (12) by a needle-driving mechanism (23) to collect a sample liquid from the sample container. A depth information acquirer (52) acquires insertion depth information, i.e., a piece of information concerning an insertion depth of the sampling needle into the sample container. A needle-rinsing length setter (54) sets a needle-rinsing length which is an insertion length of the sampling needle into a rinse storage tank (30) having an open top, based on the insertion depth information. A controller (51) controls the needle-driving mechanism so that a portion of the sampling needle extending from the tip of the sampling needle over the needle-rinsing length is inserted into the rinse storage tank. The needle-rinsing length setter is configured to set a shorter needle-rinsing length for a smaller insertion depth of the sampling needle into the sample container, to shorten the needle-cleaning time.
An analysis system includes a gripper arm for conveying a sample container, and a controller for controlling the gripper arm. The gripper arm includes a first gripper and a second gripper for holding the sample container by pinching the sample container, a drive mechanism that changes a size of a gripping space between the first gripper and the second gripper, and a photoelectric sensor for emitting light to the gripping space to detect the light from the gripping space. The controller determines the presence or absence of the sample container in the gripping space based on the presence or absence of a detection signal of the photoelectric sensor.

In the present invention, when a cap is being attached to a container, an operation unit grips the cap while contacting the top surface of the cap, on which a threaded portion is formed, and brings the gripped cap into contact with the container. A buffer unit absorbs pressing force applied from the cap to the operation unit. A control unit executes, in order: a control for causing a rotation-driving unit to rotate in a first direction, thereby fastening the cap gripped by the operation unit onto the container; a control for causing the rotation-driving unit to rotate in a second direction, thereby loosening the cap gripped by the operation unit from the container; and a control in which the rotation-driving unit is rotated in the first direction, as a result of which the cap gripped by the operation unit is fastened onto the container.

The present invention comprises: a reference value searching step for searching for a reference value R from among N measurement values; a selection step for selecting M measurement values by excluding, from the estimation target, N-M measurement values, as outliers, in descending order of deviation from the reference value R, among the N measurement values, on the basis of the reference value R searched for in the reference value searching step; and an estimation value calculation step for setting an average value of the M measurement values selected in the selection step as an estimation value of a true value. The reference value searching step includes a loop repeating from a state n=N until n=1, a process for determining the median or average value of the n measurement values, excluding one measurement value with the largest deviation from the median value or the average value among the n measurement values, and setting n-1 measurement values as candidates for the reference value R, and after the loop ends, one last remaining measurement value as the candidate is set as the reference value R.
