Abstract: An in vivo, decomposable medical implant is provided and comprises a metal material that contains, as a main alloying constituent, tungsten or a metal from the group rhenium, osmium, and molybdenum. The method for decomposing the implant, via corrosion in a bio system, includes the step of changing the pH level of the bio system, at least at the site of the implant, from a corrosion-inhibiting level to a corrosion-promoting level.

Abstract: A process for producing implants made of a bioresorbable metal, particularly magnesium alloys or zinc alloys, in which the material properties of the magnesium or the zinc are changed and the processing and utilization properties are improved by combining process steps for adjusting the properties of the material and subsequent machining. In this way it is possible to produce thin-walled tubular implants, particularly blood vessel support stents, from bioresorbable magnesium or zinc alloys, which are readily deformable without the risk of fracture during implantation.

Abstract: A monolithically integrated circuit for linear image scanning is coupled through clock pulse-supplied transfer gates to a number of readout charge transfer devices and has an overflow drain zone and an overflow gate disposed between the drain zone and the sensors connected to a clock pulse for selectively permitting transfer of charge between the sensors and the drain zone, with the sensors divided into groups representing image lines. The linear image scanning circuit operated by the interlacing method by which partial images are generated by different groups of sensors. The clock pulse controlling the overflow gate restricts the integration times of the various groups of sensors so that during the scanning of the partial images generated thereby, overlapping of the image data of one line of adjacent partial images is eliminated.

Abstract: A color image scanning circuit has a linear image sensor with photodiode sensor elements disposed in two adjacent rows integrated on a semiconductor substrate. The sensor elements are divided into groups with all sensors in each group being covered with one of several different color filters. An overflow gate is provided on the substrate between the rows of sensor elements for each group of sensor elements and are provided with individually variable clock pulse voltages for selectively varying the integration time of each group of sensor elements. By selective dimensioning of the respective integration times, compensation of the varying spectral light-sensitivities of the sensor elements can be accurately and simply achieved for generating balanced output signals for each sensor element group.
