  • Patent number: 11994529
    Abstract: The object of the invention is to avoid a decrease in dispensing accuracy of a sample, a reagent, or the like as a temperature changes. In an automatic analyzer, a dispensing nozzle sucks the sample from a sample container holding the sample and discharges the sample to a reaction container. A syringe pump controls an amount of change in a volume of water. A first pipe connects the dispensing nozzle and the syringe pump. An electromagnetic valve flows or stops the water. A second pipe connects the electromagnetic valve and the syringe pump. A branch pipe branches the water. A third pipe connects the electromagnetic valve and the branch pipe. A case accommodates at least the syringe pump, the first pipe, the electromagnetic valve, the second pipe, the branch pipe, and the third pipe. Further, the third pipe includes a heat exchange unit that performs heat exchange of the water.

  • Publication number: 20240106361
    Abstract: A drive system of an embodiment includes an initial phase command generation unit, a rotor phase detection unit, and a drive control unit. The initial phase command generation unit generates a phase command value corresponding to an initial phase of a rotor before startup of a synchronous motor. The rotor phase detection unit detects a phase of the rotor and outputs the phase. The drive control unit controls the driving of the synchronous motor by using the phase command value. The initial phase command generation unit adjusts the phase command value to approach the phase of the rotor of a detection result by using the detection result of the phase of the rotor detected before the startup by the rotor phase detection unit.
