  • Patent number: 6665504
    Abstract: A fusing device of an electrophotographic image forming apparatus includes a tubular internal pipe sealed at its ends to maintain a predetermined internal pressure to accommodate a predetermined amount of a working fluid in its inner space, a heater installed to wrap the internal pipe to generate heat, a power supply unit electrically connected to the heater to supply an external power to the heater, a cylindrical roller installed to wrap the heater, and end caps installed at both ends of the cylindrical roller. Each of the end caps includes a large-diameter portion in which an electrode electrically connected to the power supply unit is to be installed, and a small-diameter portion fittingly fixed to the end of the cylindrical roller by a locking unit. The fusing device has the end caps at both ends of a fusing roller to supply securely electricity from the power supply unit to the heater supplying heat to the fusing roller, thereby providing a maximized durability and operating safety to the fusing roller.

  • Patent number: 6635000
    Abstract: The roller for a running-gear mechanism or for a roller battery in a cableway system has a roller body formed with a central bore in which a bearing is located. The roller is provided with two flanged disks and a virtually non-elastic annular support for a cable of the cableway system between the disks. One or both of the flanged disks is fastened releasably on the roller body in that the outer circumferential surface of the roller body is formed, in the region of the abutting end surface of said roller body, with at least one encircling groove for a spring ring or the like that holds the removable flanged disk on the roller body. A resilient insert is arranged between the support and at least one of the flanged disks.

  • Patent number: 6620084
    Abstract: The invention includes an end cap that can be securely mounted to the end of a ceramic spool. The end cap comprises a locking plate adapted to fit into a groove in the ceramic spool. A plurality of angularly offset holes in the locking plate align with similar holes in the end cap. Screws or pins are placed in the holes and welded in place to prevent backing out or loosening. In use, the locking plate is secured by the pins, the groove and the inside surface of the end cap, the combination of which inhibits misalignment. Thermal cycling does not loosen the end cap, cause eccentric rotation or crack the ceramic spool.

  • Patent number: 6604462
    Abstract: A sleeve for pressing rollers consists of an internal tube made of expandable material whose inside diameter is adapted to the diameter of the roller that is intended to carrying said material and that is connected with an outer dimensionally stable casing tube. To prevent oscillations of the casing tube that would impair good printing, the latter is provided at its terminal areas with carrying discs or bushings that at least have segments whose boreholes are adapted to the diameter of the roller with a snug fit or a pressing fit.

  • Patent number: 6592503
    Abstract: A roll has a continuous tubular roll shell (11) of a composite material and axle journals (12) rotating together with the roll shell and joined to each end of the roll shell. The axle journals are supported on a supporting element (13) surrounding the axle journal (12) by at least two bearing elements (14, 15) located at a distance from each other in the axial direction (X—X) of the roll, which supporting element (13) for its part is supported on the machine frame structures (R). The first bearing element (14, 15) is supported on the supporting element (13) through a bending mechanism (20, 21), which is used for applying to the first bearing element (14, 15) a force affecting in a radial direction in order to deflect the first bearing element (14, 15) in relation to the central axis (X—X) of the unbent roll, whereby the axle journal (12) will bend in relation to a pivot point which is formed at the second bearing element (14, 15) and a bending moment is applied to the roll shell (11).
