  • Patent number: 6533525
    Abstract: An extendable loading floor for a motor vehicle has a supporting element which is fitted to the loading floor and can be adjusted along an associated supporting rail which extends in the pull-out direction and is connected to the vehicle. The loading floor is adjustable between a retracted position and en extended position. In order to simplify the design of a loading floor of this type, lifting apparatuses are connected to the vehicle and support the loading floor in the vicinity of the loading edge. The lifting apparatuses are designed to carry out a lift. In addition, the supporting rail rises, by a difference in level corresponding to the lift of he lifting apparatus, between a first rail section which faces away from the loading edge and in which the supporting element of the loading floor is supported in its retracted position, and a second rail section which faces the loading edge and in which the supporting element of the loading floor is supported in its extended position.

  • Patent number: 6494663
    Abstract: A method and system for sharing robotic mechanisms between physically remote storage libraries in an automated storage library system includes routing robotic mechanism guide structures between the storage libraries. The guide structures run through robotic mechanism transfer ports located on the sides of the housing enclosures of the storage libraries. A robotic mechanism within an first storage library moves through the transfer port of the enclosure of the first storage library onto the guide structure. The robotic mechanism then moves out of the enclosure of the first storage library along the guide structure towards a second storage library. The robotic mechanism then moves along the guide structure through the transfer port of the enclosure of the second storage library and into the second storage library for performing operations such as accessing media objects within the second storage library.

  • Patent number: 6464444
    Abstract: A chip peeling apparatus has a plurality of protrusions which include first protrusions and second protrusions lower than the first protrusions. A vacuum pump communicates through holes with grooves defined between adjacent ones of the protrusions. A UV sheet is attached to chips, and the chips are supported in the vicinity of their corners by the tops of the first protrusions. When the vacuum pump is actuated, the chips and streets disposed between the chips are lowered, and the chips are curved and supported in abutment against the tops of the second protrusions. Each of the chips is gradually peeled off the UV sheet under a force tending to recover the original shape of the curved sheet. The chip peeling apparatus is effective in preventing the chips from being damaged and positionally deviated when the chips are attracted and carried.

  • Patent number: 6457928
    Abstract: An easily installed inter-row transfer unit is disclosed employing a movable cartridge bin assembly suspended via linkage from a pair of bearing blocks, wherein the resulting bin assembly carriage travels horizontally along a support housing extending between front-to-back arrangements of rows of library systems, to enable expansion of the library systems into very large mass storage systems. The pair of bearing blocks of the bin assembly carriage are spread or closed to respectively raise or lower the bin assembly from or into a respective library system. Thus, vertical as well as horizontal motions of the bearing blocks are controlled by a motor/cable drum drive device secured to the support housing. In a preferred embodiment, a trapdoor mechanism and a cooperating roller support mechanism are used to enable reversing the direction of horizontal translation of the bin assembly carriage with a single motor/cable drum drive device. Various other embodiments and modifications are illustrated.

  • Patent number: 6454508
    Abstract: A workpiece loading interface is included within a workpiece processing system which processes workpieces, typically wafers, in a vacuum. The workpiece loading interface includes two separate chambers. Each chamber may be separately pumped down. Thus, while a first cassette of wafers, from a first chamber is being accessed, a second cassette of wafers may be loaded in the second chamber and the second chamber pumped down. Each chamber is designed to minimize intrusion to a clean room. Thus a door to each chamber has a mechanism which, when opening the door, first moves the door slightly away from an opening in the chamber and then the door is moved down parallel to the chamber. After the door is opened, a cassette of wafers is lowered through the opening in a motion much like a drawbridge. The cassette may be pivoted within the chamber when the position from which wafers are accessed from the cassette differs from the position from which the cassette is lowered out of the chamber.
