  • Patent number: 10354903
    Abstract: Provided is a load port capable of loading and unloading a substrate by a transfer robot in a state where a purge gas atmosphere is maintained inside a substrate storage space. After the lid of the substrate storage container is opened, an opening portion of the substrate storage container is closed by a frame sealing a peripheral edge of the opening portion of the substrate storage container and a shutter portion where a plurality of shielding plates are disposed in a vertical direction at a third position which is further moved forward from a release position. The shutter portion can locally move all or a portion of the shielding plates to form a narrow opening portion (third opening portion), and transferring of the substrate in the state where an atmosphere of the substrate storage space is replaced is performed through the narrow opening portion (third opening portion).

  • Patent number: 9437466
    Abstract: Provided is a wafer stocker that can prevent the inflow of an external atmosphere, maintain a wafer storage space at a desired atmosphere with a relatively small amount of gas, and prevent dust from being attached to a wafer surface. A shutter portion, including multiple shield plates having the same height as an interval between shelf plates disposed in a storage container, is disposed with a slight space from a body portion, and by supplying clean gas into the storage container, a clean atmosphere of a higher pressure than an external environment is maintained, and a shutter portion is opened and closed by moving up and down the shield plate independently from the shelf plate that supports a wafer.

  • Publication number: 20060216137
    Abstract: The present invention relates to a transporting apparatus and a transporting control method for thin plates, the apparatus for transporting the thin plates such as liquid crystal display panels and glass plates into a processing chamber, comprising a rather large robot (14) having rotating arms (16) for transporting large-sized thin plates. The transporting apparatus and a thin plate transporting system can stably raise the plates up to the heights of approximately 2 m and can transporting the plates with the deflected amount of the extended rotating arms (16) compensated. A horizontal support table (13) liftably cantilevered on two upright support members (12) is provided in the apparatus, and the transporting robot (14) with the rotating arms (16) is placed on the horizontal support table (13). Also, the deflected amount of the extended rotating arms is compensated by raising the height of the horizontal support table (13) based on the deflected amount.

  • Patent number: 6652212
    Abstract: A cylinder of the invention can precisely send out a piston rod 3 into four different positions and comprises: a spring receiving member 14 placed coaxially with piston rod 3 in a piston room (I-II) of a cylinder tube 2 so that the movement of spring receiving member 14 is limited by one end of the piston room; a first spring member 15 to separate the spring receiving member from the piston; a stopper 8 formed on piston rod 3 to limit spring receiving member 14 from moving in the opposite direction to piston 4, a hollow 9 formed on the periphery of piston rod 3 at farther position from piston 4 than stopper 8; and a stop pin 11 installed in the cylinder tube to be pressed in the direction of hollow 9 by a second spring member 12 to engage with hollow 9, wherein the movable length of piston rod 9 while stop pin 11 is engaged with hollow 9 is larger than movable distance of spring receiving member 14 from the piston. A load port and a production system of this invention are constructed using the cylinder.
