Abstract: A photosensitive drum for use in an image forming apparatus has a cylindrical member with a photosensitive layer thereon; a first gear provided at one end of said cylindrical member in an axial direction thereof; and a helical gear as a second gear provided at said one end of said cylindrical member adjacent to and outside of said first gear in the axial direction of said cylindrical member, said helical gear having a diameter larger than a diameter of said first gear. The helical gear meshes with a drive gear provided in a main body of the image forming apparatus to receive the drive force of a motor provided in the main body for rotating said photosensitive drum when said photosensitive drum is used for the image forming apparatus, and said first gear meshes with a gear of the transfer roller provided in the main body to transmit the drive force of said photosensitive drum to the transfer roller. The first gear and said helical gear are integrally formed as a gear portion, said integrally-formed gear portion comprising a through-bore portion having a first portion, and a second portion, said first portion being disposed outside of said second portion in the axial direction of said cylindrical member and having an inner diameter that is smaller than an inner diameter of said second portion, said first portion being fitted on a drum shaft when said photosensitive drum is mounted in the image forming apparatus.      The drive force of the motor acts on a root portion of the shaft which supports one end of the photosensitive drum. Therefore, the inclination of the shaft can be reduced such that, when the photosensitive drum is rotated, it does not vibrate with respect to the shaft, allowing the drum to be smoothly rotated with high accuracy.

Abstract: On receiving a symbol sequence carried by a first-polarization and a second-polarization signal of two orthogonally polarized signals and in order to cancel a cross polarization interference (XPI) component which leaks from the second-polarization signal into the first-polarization signal, a first decision feedback XPI canceller (43) is supplied with a before processed signal derived from the second-polarization signal and with a decided signal which is produced by a decision circuit (22) and which represents the symbol sequence carried by the second-polarization signal with an intersymbol interference component and another XPI component cancelled from the before processed signal.  Another decision feedback XPI canceller (44) is similarly operable.  Preferably, a first decision feedback equalizer (41) is supplied with another before processed signal derived from the first-polarization signal and with another decided signal which is produced by another decision circuit (21) and which represents the symbol sequence carried by the first-polarized signal with another intersymbol interference component and the first-mentioned XPI component cancelled from the last-mentioned before processed signal.  A second decision feedback equalizer (42) is similarly used.          Alternatively, a delay element is used instead of each decision feedback equalizer if the intersymbol interference components are negligible.

Abstract: A  device  for  implanting  endoprostheses  (1)  has basically a tubular outer body (2) and an elongated core element (3) placed inside of this. To operate the device, both the core element (3) and the tubular body (2) are provided with handles (5, 6) at their proximal ends.  In order to produce a form-locking connection between the endoprosthesis  (1)  and the core element  (3),  the core element (3) exhibits a region (10) in which is impressed a relief corresponding to the inner form of the endoprosthesis (1).  As a result of this, there are a great number of form- locking  meshing  sites  between  the  enclosed,  folded endoprosthesis (1) and the core element (3).  A device with this   type of   design   permits   partially   released endoprostheses (1) to be folded back up again by pushing the tubular body (2) forward so that the endoprosthesis (1) may be repositioned.  In addition, sure and reliable operation is achieved by this type of stamping of the core element (3).
