Abstract: In the non-volatile storage unit (341) of the local control unit (34) of each unit (3 to 6) configuring an LC system, periodic inspection information, such as the installation date and the next inspection scheduled date, is stored at an appropriate time. When an analysis is carried out, in the system control unit (2) which controls each unit, a periodic inspection notification processing unit (211) collects periodic inspection information from each unit (3 to 7) upon power on or start up, compares the next inspection scheduled date with the current time by the real-time clock (212), and determines a unit for which a periodic inspection notification is required. If there is a unit that requires a periodic inspection notification, a notification request is sent to the unit, and the local control unit (34) of the unit outputs an indication prompting periodic inspection to the display unit (35). As a result, even if the installation times are different for each unit and even if each unit does not have a real-time clock, it is possible to notify a user when a predetermined age of service has passed from the installation time of a given unit.

Abstract: A data processing apparatus according to one aspect is provided with an inference unit configured to predict at least one objective variable from a plurality of explanatory variables by using a trained model, and a display data generation unit configured to generate data for displaying an inference result by the inference unit. The inference unit is configured to set a first explanatory variable selected from the plurality of explanatory variables as a variation value and set second explanatory variables other than the first explanatory variable as fixed values. The inference unit predicts, by using the trained model, the at least one objective variable when the first explanatory variable is continuously varied within a predetermined variation range. The display data generation unit generates data indicating a variation of the at least one objective variable with respect to a variation of the first explanatory variable.

Abstract: A correspondence relationship between an inspection item and an operator code assigned to each operator of an analysis unit is acquired by a correspondence relationship acquirer. Operation commands assigned to operators to be operated for execution of an inspection of the analysis unit are sequentially transmitted to the analysis unit based on the inspection item and the correspondence relationship. A request command requesting transmission of screen information representing a screen to be displayed in the display panel of the analysis unit is transmitted to the analysis unit. The screen information that has been transmitted by the analysis unit in response to the request command is acquired by a screen information acquirer. The analysis unit behaves based on the operation command assigned to the operated operator and a screen responding to the behavior of the analysis unit is displayed in the display panel of the analysis unit.

Abstract: A stress luminescence measurement method according to one aspect includes the steps of: placing a stress luminescent material on a surface of a sample; irradiating the stress luminescent material with excitation light; acquiring a first captured image by imaging the stress luminescent material during irradiation of the excitation light; applying a load to the sample; acquiring a stress luminescence image by imaging stress luminescence of the stress luminescent material; irradiating the stress luminescent material after removal of the load with the excitation light; acquiring a second captured image during irradiation of the excitation light by imaging the stress luminescent material in a state in which the load has been removed; and storing the first captured image and the second captured image in a memory in association with the stress luminescent image.

Abstract: An analysis system, controller, and data processing device that are capable of avoiding the influence on control in the case where the names of the constituent elements are changed. The analysis system includes a plurality of constituent elements used for analysis; a controller configured to perform control on a basis of data received from the constituent elements; and a data processing device configured to process data received from the controller. The controller receives the control code, the additional code, and the name information from the plurality of constituent elements to generate an ID code on the basis of the control code and the additional code. The data processing device receives the ID code and the name information from the controller, and performs control on the basis of the control code included in the ID code.
