  • Patent number: 10422808
    Abstract: A rinse mechanism rinses reaction cuvettes with first and second detergents. An R1 reagent pipetting mechanism 8 rinses the reaction cuvettes that have been rinsed by the rinse mechanism with a special detergent. A counting unit counts and stores in a storage unit a use frequency of each reaction cuvette for a specific reagent item. A determining unit determines whether the counted use frequency exceeds a predetermined threshold N1. A control unit controls the R1 reagent pipetting mechanism such that, in a case where the counted use frequency exceeds the predetermined threshold N1, the reaction cuvettes, which have exceeded the predetermined threshold N1, are soaked with the special detergent only for a period equal to or less than a value derived by multiplying a pipetting cycle time, which indicates a period when a sample is pipetted, by the total number of reaction cuvettes and a predetermined integer.

  • Publication number: 20190243483
    Abstract: A touch panel driving device, for sequentially performing scanning for selecting a pair of adjacent transmission signal lines and a pair of adjacent reception signal lines on a touch panel, includes a reception circuit configured to receive reception signals whose waveforms are changed by a capacitance change caused by an operation from the pair of reception signal lines of the touch panel and generate a detection value for monitoring a touch panel operation. The reception circuit generates the detection value by comparing levels of the reception signals from the reception signal lines while sequentially switching capacitance values of a measurement capacitance unit connected to one of the reception signal lines. The measurement capacitance unit includes capacitance units each forming a certain capacitance value by parallel connection or series connection of capacitors as a capacitance unit forming one capacitance value used for switching the capacitance value of the measurement capacitance unit.

  • Publication number: 20150234375
    Abstract: An axial offset correcting method of a tool coordinate system of a robot also including an inclination offset correction is provided. A first workpiece is grasped by a tool. The operation of a robot arm is controlled by using detecting quantities of a force sensor, thereby starting a fitting of the first workpiece into a second workpiece. A position of an origin of a mechanical interface coordinate system in at least two different states during the fitting operation is obtained, thereby obtaining a position of a central axis of the first workpiece. An inclination offset quantity of the tool coordinate system is calculated based on the position of the central axis of the first workpiece. An inclination offset of the tool coordinate system is corrected based on the calculated inclination offset quantity.
