Abstract: A printed image is produced at least one printed image location using a printing machine with at least one illuminating device that produces at least one printed image at a number of printed image locations. These respective printed images belong to the same page of a printed product to be produced by the printing machine. This page of the printed product exists in the form of a file containing image data before it is produced as the printed image. That file contains image data of all of the printed images of the page of the printed product. A raster image processor is aligned with each printed image location and converts only image data of the printed images of the page of the printed product into raster data, with that printed image being assigned to a respective printed image position. A network is provided for use in the electronic communication of at least image data. Each raster image processor is connected to this network by an interface which receives data.

Abstract: A laser and electroabsorption modulator (EAM) are monolithically integrated through an etched facet process. Epitaxial layers on a wafer include a first layer for a laser structure and a second layer for an EAM structure. Strong optical coupling between the laser and the EAM is realized by using two 45-degree turning mirrors to route light vertically from the laser waveguide to the EAM waveguide. A directional angled etch process is used to form the two angled facets.

Abstract: A reception coil maintaining element for an MR-imaging system includes two phase-controlled multi-element arrays of an RF multi-channel surface reception coil. Both of these phase-controlled, multi-element arrays have a reception surface including a center having a longitudinal axis that crosses that center. Each of these multi-element arrays is arranged on an arm which can pivot about a common pivotable axis. A vertical first plane is parallel to this pivotable axis. A vertical left plane extends along the longitudinal axis of the center of the left reception surface of the left multi-element array. A vertical right plane extends along a longitudinal axis of the center of the right reception surface of the right multi-element array. Both of these vertical left and right planes have approximately the same spacing with respect to the vertical first plane of the pivotable axis where the reception coil maintaining element in accordance with the present invention is in its operational state.

Abstract: A register in a printing machine is controlled and adjusted by providing at least one printing unit provided with at least two printing groups in the printing machine. Each printing group comprises a cylinder pair consisting of at least a forme cylinder and a transfer cylinder. The forme cylinder of the first printing group is phase shifted at a first amount for the register adjustment in a circumferential direction. The transfer cylinder of the first printing group is phase shifted in a second amount in the circumferential direction. The amount of the phase shift of the forme cylinder is different from the amount of phase shift of the transfer cylinder. The two amounts of the phase shifts are not equal to zero.

Abstract: A printing unit has at least one press unit having a plate cylinder with at least one printing plate that can be mounted on the plate cylinder and which carries a printing image. The plate cylinder has at least one cylinder channel in which ends of the printing plate can be fixed or positioned.
