  • Patent number: 11863374
    Abstract: In a distributed control system, when the determination that an error has occurred is made as a result of comparison of correct connection information retained in a storage unit and connection information of an actually connected control object device or terminal communication device by a comparison unit, a central computation device outputs a display signal of an abnormal part to a display device, and the display device displays the abnormal part on the basis of the display signal. A distributed control system and an automatic analysis device provided with the same, and an automatic analysis system are thereby provided, whereby an erroneous connections or defects can be more easily and reliably detected than in the prior art, even when a plurality of control boards are distributedly arranged in the same device.
    Type: Grant

  • Patent number: 10933834
    Abstract: A vehicle roof structure includes a reinforcement extending in a width direction of a vehicle between two roof side rails on the opposite sides in the width direction. The load transmission member includes a first coupling portion that couples the load transmission member to the reinforcement and a second coupling portion that couples the load transmission member to one of the roof side rails. A load transmission portion is located between the first coupling portion and the second coupling portion when the load transmission member is viewed in the front-to-rear direction. The load transmission portion includes a part extending straight in the width direction. An inflator supporting portion extends from the load transmission portion.
