  • Patent number: 11217829
    Abstract: A battery pack is provided which includes a battery, a circuit board equipped with load feed lines, bus bars connecting with the battery and the circuit board, first and second switches, and third to sixth switches. The first and second switches are disposed in a housing which is higher in capacity of heat dissipation than the circuit board. The third to sixth switches are disposed on the circuit board. The first and second switches are larger in amount of electrical current flowing therethrough than the third to sixth switches on time average. This enables the size of the battery pack to be reduced without sacrificing the dissipation of heat from the switches.

  • Patent number: 11209405
    Abstract: Before repeating the processing that an LC/MS analysis is performed after diluting a large number of pretreated media samples (S16 to S19), an LC-MS stabilization processing (S11) of supplying a mobile phase to the LC-MS and performing an analysis without a sample according to the same gradient profile as that in a culture medium sample analysis and a standard sample analysis (S13) of supplying a standard sample to the LC-MS and obtaining data for generating a calibration curve are performed. Before the LC-MS stabilization processing and before the standard sample analysis, respectively, a standby time corresponding to a required time of a sample dilution is provided (Steps S10 and S12). With this, the time of the cycle including the LC-MS stabilization processing and the time of the cycle including the standard sample analysis are made to be the same as the time of the cycle of a dilution and an analysis to a culture medium sample.

  • Patent number: 11209404
    Abstract: A data storage section stores LC/MS analysis data for a large number of culture-medium samples acquired with an LC-MS. Based on those data, a quantitative analyzer calculates concentration values of a large number of compounds in each sample and stores the result in an analysis result storage section. A result display processor retrieves analysis results with the same culture name and different sampling date from the analysis result storage section, creates a table in which concentration values are arranged for each compound and for each sampling date, as well as a graph showing a temporal change in the concentration value of one compound, and displays the table and graph on the same window on a display unit. An operator using an operation unit selects a compound on the displayed table. The result display processor creates a graph for the selected compound and renews the graph on the display.

  • Patent number: 11097620
    Abstract: A circuit system for a railroad vehicle according to an embodiment includes a power conversion unit, a first converter, a second converter, a power storage unit, and a control unit. The power conversion unit converts power supplied from an overhead wire into power for driving a motor for running mounted on a railroad vehicle. The first converter converts power supplied from the overhead wire into DC power. The second converter converts power output from the first converter into power for driving a load mounted on the railroad vehicle. The power storage unit is electrically connected to an input side of the second converter. The control unit inputs regenerative power output from the power conversion unit to the first converter and inputs power output from the first converter to the power storage unit in a case where it is determined that the railroad vehicle is being regenerated.

  • Publication number: 20210208945
    Abstract: An information processing apparatus (100) has a ring buffer (113) and a save area (117). A log generation unit (108) generates a log of an application (107) in the ring buffer (113). A resource monitoring unit (109) monitors a current resource-usage amount for the application (107). A rule collation unit (111) determines whether the current resource-usage amount for the application (107) meets a log saving condition that is a condition for saving the log of the application (107). A log saving unit (112) saves, in the save area (117), the log in the ring buffer (113), if the current resource-usage amount for the application (107) is determined by the rule collation unit (111) to meet the log saving condition.
