  • Publication number: 20220128532
    Abstract: An object is to accurately detect peaks of various compositions, even in a case of unseparated peaks in which peaks of a plurality of compositions are superimposed. A computer acquires waveform data D1 having a peak P1 in a composition A measured by a data analysis device (S10). Next, the computer acquires waveform data D2 having a peak P2 in a composition B measured by the data analysis device (S20). Next, waveform data D12 including unseparated peaks by superimposing the waveform data D1 including the acquired peak P1 and the waveform data D2 including the acquired peak P2 (S30) is generated. Next, the generated waveform data D12 of the unseparated peaks is input as learning data, and the waveform data D1 and D2 corresponding to the waveform data D12 are input as training data in Step S40. Next, machine learning is performed using the waveform data D12, D1, and D2, and a learned model for estimating an accurate separation method of unseparated peaks is constructed based on the trained result (S50).

  • Patent number: 10444207
    Abstract: An analyzer control system 20 for monitoring and controlling an analyzer 20 includes: a plurality of sensors for detecting the condition of each component of the analyzer; a potential problem inference section 23 for receiving detection results obtained with all or part of the sensors and for inferring whether or not the analyzer is in a potentially problematic condition; and a potential problem display section 32 for showing, on a display screen, information on the potentially problematic condition. The “potentially problematic condition” is neither a condition in which the analysis data being collected by the analyzer are unusable, nor a condition which requires deactivation of the analyzer; it is a condition in which the analyzing operation may be continued for the time being, although the analyzer is likely to soon fall into the aforementioned situations if the operation is further continued. The already collected data can be properly used.

  • Patent number: 8104330
    Abstract: In order to obtain a temperature gradient elution method which is rapid and accurate, a mobile phase (1) is supplied through two mobile-phase flow channels (2a) and (2b), mixed together, and introduced into the column (15) while the column (15) is made adiabatic. In this operation, the temperature of the mobile phase in one mobile-phase flow channel, i.e., the channel (2a), is regulated to a constant temperature higher than the upper limit of the target temperature range to be obtained in the column (15), while the temperature of the mobile phase in the other mobile-phase flow channel, i.e., the channel (2b), is regulated to a constant temperature lower than the lower limit of the target temperature range in the column (15). By controlling the flow rates in the two mobile-phase flow channels (2a) and (2b), the proportion in which these mobile-phase portions are mixed is changed with time to thereby change the temperature of the mobile phase in the column (15) with time.

  • Patent number: 6615252
    Abstract: Prior to sending to a requesting client device a requested multimedia application which comprises a plurality of kinds of materials and a scenario which defines a role of each material, the server converts an input (or original) format of a certain kind of materials of the requested application into a format with which the requesting client device can deal and converts format-dependent data of the scenario accordingly. This enables every consuming device to consume any of the multimedia applications stored in the server regardless of the material format with which the consuming device can deal with respective to a certain kind of materials. Four schemes different in conversion timing of the materials and the scenario are disclosed. The original format of the materials may be limited to a master data format, eg., the DV format if the certain kind of materials are moving picture materials.

  • Patent number: 6332003
    Abstract: A moving image composing system for displaying reduced and encoded images at arbitrary positions on a multi-image raster. The moving image composing system comprises a moving image reducing unit for reducing a moving image inputted, a moving image encoding unit for encoding the reduced moving image to produce an encoded moving image, an accumulating unit for storing and accumulating the encoded image, and a moving image composing unit for combining more-than-one encoded moving images accumulated to produce a multi-image combined moving image. The moving image encoding unit performs the encoding processing to facilitate the change of positional information the reduced moving image has, in consideration with the case that the change of the position information occurs due to the disposition of the reduced moving image at its combination.
