An image processing apparatus is used for copying an original. The expansion joint construction permits position changes of the building parts with respect to one another. By analyzing the reference to the name resolution server, the name resolution server is capable of dynamically generating a canonical name associated with a domain andor a host name. The system also includes a light source for illuminating the first surface of the plasmonic interferometer, a detector positioned for detecting light transmitted through the aperture, and a sample holder for disposing a sample to be analyzed onto the first surface of the plasmonic interferometer. Such a configuration of a magnet coil is suitable particularly in fuel injection valves which are used in mixture-compressing, spark-ignited internal combustion engines, but also in all other solenoid valves. The valve fixes the position of the positioning device within a tolerance of the position the positioning device was at prior to the loss of the position command.
