The mounting device is obtainable by incising a plurality of arc-shaped eyelet blanks while leaving two connection sections per eyelet blank into the surface of the base plate and production of the mounting eyelets by bending the eyelet blanks out of the base plate around a bending edge in the area of the connection sections. At least part of the eyelet blanks are arranged as groups of eyelet blanks with the latter being nested to each other. Preferably, the groups of eyelet blanks are arranged rotated relative to each other.

Said conjugate is also useful for therapy, e.g., for chemotherapy or intranuclear Gadolinium Neutron Capture Therapy (GNCT).

Abstract: A method for copy retouching digital image data which contains a periodic pattern, includes calculating a distance vector D1 from the initially defined starting positions of a read mark and a write mark. The image data are then copied from the image points located under the read mark to the image points located under the write mark. In order to avoid a possible offset of the copied pattern area with respect to the surrounding pattern, a corrected distance vector D2 is calculated in such a way that the read mark and the write mark have the same phase position in relation to the periodic pattern. The method is particularly suitable for copy retouching of screened color separation data.

Abstract: A diode network having at least one diode which during operation is located in the path of an HF signal, a predetermined diode voltage being applied to the diode to adjust its operating point, is characterised in that a control device is provided to maintain the diode voltage constant. With the invention it is advantageous that, due to the measurement of the DC voltage acting on the diode itself and influencing the operating point, it is not necessary to provide a low-resistance coupling between a voltage source and the diode, with respect to direct current.

Abstract: A circuit to reduce the temperature-dependence of a predistorter diode in a predistorter for an external optical modulator characterized in that a predistorter diode (D1, D2) is connected in series with an ohmic resistance (Rv) and the series circuit is fed from a power supply in operation, whereby the voltage V1 of the power supply and the ohmic resistance are selected such that when the temperature of the predistorter changes the curvature of the temperature-dependent current-voltage curve for the predistorter diode hardly varies at the respective operating point. One advantage of the invention is the very simply type of compensation that it allows.

This object is achieved by an optical receiver (5) which in particular is characterized in that the two ends of two optical fibers (8, 9; 12, 13; 16, 17), which serve to transmit optical signals, are arranged directly in front of the active surface (7; 11; 15) of the photo-diode (6; 10; 14) of the optical receiver (5) such that the photo-diode (6; 10; 14) can directly receive optical signals from the two optical fibers (8, 9; 12, 13;, 16, 17). This has the advantage that no additional losses occur and neither are additional components required. Furthermore the production costs are minimized and the reception quality is optimized.

Abstract: A method of stabilizing the working point of a predistorter diode of a predistorter for an optical modulator as protection from temperature fluctuations, whereby the predistorter diode is supplied with a temperature-dependent voltage in order to adjust the working point, is characterized by the fact that a reference diode is thermally coupled with the predistorter diode so that the reference diode is supplied with a constant current, whereby it is not supplied with a signal distorted by the predistorter, and the predistorter diode is supplied with a voltage which is proportional to the reference diode. One advantage of the invention is that it is possible to achieve good temperature stability in an easy manner.
