Abstract: Photomultiplier tubes differ in performance between individual products, and deteriorate over time. To appropriately use a nonlinear calibration curve, it is desirable that changes in signal level be strictly equalized. This invention includes means for, prior to sensitivity adjustment of a photomultiplier tube by application of high voltages, measuring a same sample under a plurality of high-voltage conditions, determining, from linear relationships between logarithms of each high voltage and those of signal levels, an optimal voltage for a measuring operation of predetermined order of execution in the plurality of measuring operations, and recording identification information for identifying each linear relationship; the invention assessing a healthiness level of the photomultiplier tube by assessing the linear relationship.

Abstract: In an information-providing system according to an embodiment of the present invention, when a communication terminal transmits request information for requesting a setting input screen, an information-processing device recognizes character information contained in the request information, and, by referring to history information, identifies location information corresponding to character information similar to the recognized character information. The location information identified by the information-processing device is received by the communication terminal, and this information is reflected on a setting input screen displayed on the communication terminal.

Abstract: A data search device acquires memo data to be used in a search, extracts keywords from the memo data, and then allocates ranks to the keywords. The data search device performs a search for the keywords in multiple databases to identify related data. The databases are ranked similarly to the keywords. When multiple items of related data are identified, the data search device calculates overall ranks based on the ranks of the keywords and the ranks of the databases used in the search of the items of related data, and outputs items of related data having higher ranks.

Abstract: A photomultiplier tube is susceptible to noise at a low concentration and to saturation at a high concentration. It is necessary to make a measurement with an appropriate intensity of light to provide good reproducibility and linearity. Only adjustment of reagent concentration and constituents are not sufficient to apply the photomultiplier tube to a wide range of concentration. When the sensitivity of the photomultiplier tube is to be adjusted by voltage, measurement is performed under the optimum condition by setting a voltage to be applied suitable for measurement according to a concentration range specified for measurement items and adjusting the voltage based on selected items, previous values for the selected items, diagnostic information, etc.

Abstract: An automatic analyzer for qualitatively and quantitatively analyzing biological samples includes mixing means by which magnetic particles that have undergone B/F reactions are stirred before being introduced into a flow cell. Control means are provided for performing control so that during one analytical cycle, a reaction solution containing the magnetic particles that underwent B/F reactions is suctioned in a plurality of operations into the flow cell so that the solution is stirred by the mixing means prior to each of the suctioning operations.

Abstract: An analyzer which collects magnetic particles for immunological analysis includes a magnetic separator adapted to efficiently separate within a short time a reaction product formed by bonding substances such as an object to be measured and the magnetic particles, and a nonmagnetic component other than the reaction product, from a liquid mixture in a vessel of the magnetic separator To perform the separation, a magnet complex having multiple magnets and magnetic materials stacked in alternate form so that magnetic pole pieces on opposed sides of each magnet are homopolar, is disposed outside the vessel that holds a liquid in which the magnetic particles are suspended.
