Abstract: An accuracy management method for executing accuracy management by using an accuracy management substance in a measurement device that measures a biological specimen includes: reading management information regarding the accuracy management substance from an information recording medium; selecting a treatment adapted to the read management information; executing the selected treatment; and updating the management information in the information recording medium according to the executed treatment.

Abstract: This eyewear is provided with: a frame; a lens which is supported by the frame, and which includes an optical characteristic varying portion having an optical characteristic which is varied by means of electric control; a communication portion for receiving information from an external terminal; and a control portion for controlling the optical characteristic varying portion on the basis of the information received from the external terminal.

Abstract: A liquid chromatography device includes a column containing a filler, an injection valve capable of introducing a sample into the column and also capable of introducing a liquid mobile phase into the column, and a mobile phase feeder for feeding the liquid mobile phase from a mobile phase container containing the liquid mobile phase to the column via the injection valve. Between the mobile phase container and the injection valve is provided a storage chamber for temporarily storing the liquid mobile phase sent from the mobile phase container. The device further includes a liquid level detection sensor for detecting the liquid level of the liquid mobile phase in the storage chamber. This structure allows the liquid for use in analysis to be used completely without being wasted.

Abstract: The present invention relates to a method of manufacturing an analytical tool, where the method includes a reagent member forming process for preparing a reagent member containing a reagent to react with a specific component contained in sample liquid. The reagent member forming process includes a plurality of applying and drying steps in which material liquid containing a reagent is applied and then the material liquid is dried. The applying and drying steps may be performed with use of material liquid containing the same reagent, for example. The applying and drying steps are performed 2-200 times, for example.
