  • 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.

  • Patent number: 11994158
    Abstract: A clearance adjusting member that easily attaches and detaches without risk of falling off a pin is disclosed. A first member and a second member are coupled freely to be rotated in relation to each other by a cylindrical pin. For adjusting an axial clearance between the two members, the clearance adjusting member comprises a shim in a U or C-shape attached to the pin in the axial clearance, and a restricting means for restricting the shim while being freely releasable. A restricted piece protruding radially outward is formed on an outer circumferential edge of the shim. The restricting means includes a pair of restricting pieces spacedly arranged circumferentially on the radially outer side of the pin. When the shim is inserted towards the axial clearance, the restricted piece becomes positioned between the pair of restricting pieces and the shim is attached to the pin.

  • Patent number: 11993912
    Abstract: Provided is a work machine that can suppress decrease in work efficiency while reducing the possibility of contacting a worker or a dump truck, etc. A movement range is set in advance so as to avoid entry of a worker or a dump truck, etc. into the set movement range. The work machine performs stop control with clearance for an obstacle having entered the movement range, but performs stop control with relatively small clearance (minimum clearance) for a movement range. Thus, the work machine can reduce the frequency of stopping a body or a work implement and suppress decrease in work efficiency. Since the work machine controls the body or the work implement to stop with clearance when the worker or the dump truck, etc. enters the movement range of the work machine, the work machine can reduce the possibility of contacting the worker or the dump truck, etc.
