  • Patent number: 10786778
    Abstract: A power supply control device of a nitrogen gas generator includes: a pipe having a nitrogen gas inlet for receiving input of nitrogen gas from a nitrogen gas generator that compresses air by a compressor to separate the nitrogen gas from the air, and a nitrogen gas outlet for outputting, to outside, the nitrogen gas received by the nitrogen gas inlet; a pressure gauge that measures pressure inside the pipe; a flowmeter that measures a flow rate of the nitrogen gas flowing inside the pipe; and a control unit that controls supply of power to the compressor and shut-off of the supply of the power in accordance with a measurement result of at least one of the pressure gauge and the flowmeter.
    Type: Grant

  • Patent number: 9702850
    Abstract: To provide an electrophoresis method and an electrophoresis device which can reduce difficulty in operation while implementing sufficient staining. An electrophoresis device includes a temperature gradient tank, a dispenser, a holder storage cabinet, a photographing unit, a PCR device, a chip rack, a chip disposal box, a DC power unit, a control unit, an arm, and a liquid feeder. A holder and a cassette removably attached to the holder are put on the temperature gradient tank. The control unit controls a carrying device, the arm, the liquid feeder, the temperature gradient tank, an excitation light source and a camera in the photographing unit, and the DC power unit. The control unit prestores a program for executing the control operation in its internal memory.
