    Abstract: The present invention is adapted to make light beams emitted from a light source enter a photodetector both when interposing an optical element having known characteristics and when not interposing the optical element, and acquire a first output value and a second output value that are the output values of the photodetector with respect to each of light beams that respectively have predetermined multiple wavenumbers and are included in the incident light beams, and obtain an arithmetic expression for calculating intensity of incident light beams from an output value of the photodetector, using parameters that are a ratio between the first output value and the second output value at each of the predetermined wavenumbers and the wavenumber transmission or reflection characteristic of the optical element.

    Abstract: An analyzer that analyzes a measurement sample on the basis of spectrum data obtained by irradiating the measurement sample with light and includes a total analysis value calculation part that, on the basis of the total analysis value of a reference sample of which the total analysis value of multiple predetermined components are preliminarily obtained, calculates the total analysis value of the multiple components in the measurement sample from the spectrum data of the measurement sample.

    Abstract: In order to prevent leakage, a fluid control apparatus is adapted to include: a valve provided in the flow path through which the fluid flows; a pressure sensor provided upstream of the valve; a flow rate sensor provided downstream of the pressure sensor; a reference pressure determination part that is inputted with a measured flow rate from the flow rate sensor and on the basis of a flow rate-pressure map, determines a reference pressure corresponding to the measured flow rate; a reference flow rate calculation part that calculates a reference flow rate so that the deviation between the reference pressure and a measured pressure measured by the pressure sensor decreases; and a valve control part that controls the opening of the valve so that the deviation between the reference flow rate and the measured flow rate decreases.

    Abstract: The present invention provides an interferometer and the like, that is capable of ensuring the speed stability of the movable mirror while achieving the speed up of the reciprocal movement of the moving mirror and suppressing the increment of the maximum instantaneous thrust force required for the turning back as much as possible. The interferometer includes a moving mirror, a movement mechanism for reciprocating the moving mirror, a movement control part for controlling the movement mechanism and allowing the moving mirror to be reciprocated at a constant speed, and a measurement part for measuring a position of the moving mirror. The movement control part is adapted to receive target position data indicating a target position of the moving mirror, and control the movement mechanism to bring the measurement position of the moving mirror measured by the measurement part close to the target position indicated by the target position data.

    Abstract: The present invention is intended to make it possible to automatically drive a test object without performing pre-learning for a running performance map for each vehicle. There is provided an automatic test object driving device that automatically drives a test vehicle based on a command vehicle speed, and that includes a driving actuator for performing driving operation of the test vehicle, and a driving control unit for controlling the driving actuator. The driving control unit includes a first accelerator map and a second accelerator map each of which indicates a relationship among a vehicle-speed-related value, an acceleration-related value, and an accelerator-depression-amount-related value. The driving control unit uses the first accelerator map to determine an accelerator depression amount corresponding to the command vehicle speed, and uses the second accelerator map to correct the accelerator depression amount by feeding back a vehicle speed and an acceleration of the test vehicle.
