  • Patent number: 11340316
    Abstract: A magnetic sensor is provided with first and second magnetoresistive effect elements that can detect an external magnetic field. The first and second magnetoresistive effect elements are a plurality of layers of multilayer body including free layers where their magnetization directions vary due to the external magnetic field. Shapes of the first and second magnetoresistive effect elements viewed from the upper side in the lamination direction are different from each other. The first magnetoresistive effect element has a shape that can increase a slope of an output of the first magnetoresistive effect element relative to the change of the external magnetic field. The second magnetoresistive effect element has a shape that can decrease a slope of an output of the second magnetoresistive effect element relative to the change of the external magnetic field compared to the slope of the output of the first magnetoresistive effect element.

  • Publication number: 20190039828
    Abstract: A warehousing/shipping-operation support system selects, for a first article in a warehousing/shipping operation, by using acquired positional information of an operator, a sign closer to a position of the operator among signs in the vicinity of a storage location of the article, and the warehousing/shipping-operation support system selects, for a second and following articles, by using the storage-location information of the article whose warehousing/shipping has been completed as the positional information of the operator, a sign closer to the position of the operator among the signs in the vicinity of the storage location of the article.
