  • Patent number: 7327978
    Abstract: A fusing member is formed from an evacuable inner tube with a cylindrical wall. The evacuable inner tube is inserted into an outer tube and the inner tube is pressurized to expand the inner tube such that the wall is in contact with the outer tube. An amount of a working fluid is then sealed within the inner tube at a below atmospheric pressure.
    Type: Grant

  • Patent number: 7304258
    Abstract: A system for transporting and selectively sorting particles includes a first wall and a traveling wave grid extending along the first wall. The system includes a second wall having a passage extending therethrough and a gate operatively associated with the passage. A controller is adapted to output a multi-phase electrical signal. The controller is in communication with the traveling wave grid and the gate. A method of using the system is also provided.

  • Patent number: 7113717
    Abstract: A fuser system of a xerographic device, including a fuser member and a pressure member in which the pressure member is made to exert pressure upon the fuser member so as to form a nip having a nip width between the fuser member and the pressure member, wherein the nip width is set to within a specification nip width range, a drive system for driving said fuser member relative to said pressure roll; a sensor for monitoring the torque of said drive system; a processor in communication with the sensor that receives torque data from the sensor, wherein the processor determines a current nip pressure uniformity from the torque data and compares the current nip pressure uniformity to the specification nip pressure uniformity range, and a nip pressure adjustment device in communication with the processor, which adjusts the current nip pressure uniformity to be within the specification nip pressure uniformity range.
