Abstract: An apparatus for the connection of articles via at least one connection element plasticizable by heat includes a cap, in particular a heatable cap, which is movable toward and away from the connection element and which has a shaft, for the forming of a rivet head at the connection element and having means for the cooling of the cap by means of a cooling fluid, in particular air. A first variant is characterized in that the shaft of the cap has a central cooling fluid supply passage preferably reaching up to and into the cap body and a plurality of respective at least generally radially outwardly directed cooling fluid passages starting from the central cooling fluid supply passage are provided within the cap body. Provision can alternatively be made that the cap is manufactured at least partly from porous, air-permeable material, in particular ceramic material, and the shaft of the cap is provided with a cooling fluid supply bore preferably reaching up to and into the cap body.

Abstract: A microelectronic device is designed such that it includes a region between electrodes having a switchable ohmic resistance wherein the region is made of a substance comprising components Ax, By, and oxygen Oz. The ohmic resistance in the region is reversibly switchable between different states by applying different voltage pulses. The different voltage pulses lead to the respective different states. An appropriate amount of dopant(s) in the substance improves the switching, whereby the microelectronic device becomes controllable and reliable.

Abstract: There is provided a method for fabricating an organic light emitting device. The method includes depositing a first electrode layer on a substrate, depositing an electrically insulating layer on the first electrode layer, depositing a second electrode layer on the insulating layer, depositing an organic layer on the second electrode layer, forming an aperture in the organic layer, depositing a light transmissive electrically conductive layer on the organic layer, and forming an electrical connection between the conductive layer and one of the first and second electrode layers via the aperture.

Abstract: An organic light emitting device has a layer structure comprising: a first electrode layer (20); a second electrode layer (40) parallel to the first electrode layer (20); and, an electrically conductive and light transmissive layer (70) parallel to the second electrode layer. An electrically insulating layer (30) is disposed between the first and second electrode layers. A layer of organic material (50) is disposed between the second electrode layer and the conductive layer. An aperture (60) in the organic layer provides an electrical connection path between the conductive layer and one of the first and second electrode layers.
