  • Loading system
    Patent number: 11834283
    Abstract: A loading system includes one or more adjusting mechanisms configured to adjust a position of the container held by the container holder, a controller configured to control operation of the one or more adjusting mechanisms, a transfer mechanism configured to move a loadable object into a holding space of the container with the container held by the container holder to transfer the loadable object to the container, and one or more position detectors. The one or more position detectors are located to detect a relative position of a loadable object when the loadable object is held by the transfer mechanism and is in the holding space.
    Type: Grant
    Filed: October 9, 2019
    Date of Patent: December 5, 2023
    Assignees: Daifuku Co., Ltd., Iwasaki Seisakusho Co., Ltd.

  • Method for decomposing thermoset resin and recovering decomposition product
    Patent number: 8653150
    Abstract: The present invention relates to a method for decomposing, in the presence of subcritical water, a thermosetting resin comprising a polyester moiety and a crosslinking moiety therewith to provide a compound comprising an acid residue derived from the polyester moiety and a residue derived from the crosslinking moiety, and collecting the compound in an efficient yield, specifically, which comprises steps of: (I) decomposing the thermosetting resin in the presence of subcritical water to provide a solid comprising a compound comprising an acid residue derived from the polyester moiety and a residue derived from the crosslinking moiety, (II) subjecting the solid to an organic solvent to dissolve the compound into the organic solvent, wherein the organic solvent has a higher solubility which can dissolve the compound than that of water, and (III) collecting, separating or isolating the compound from the organic solvent.
