Disclosed is a filter device (), particularly a liquid filter, comprising a filter element () that is disposed in a filter housing () and a heater () for heating medium flowing through the filter device (). The inventive filter device () is characterized in that the heater () is designed with at least one heating circuit () that is molded into the filter housing (). Alternatively or additionally, the heater () is designed with at least one heating circuit () which is provided with an electrical contact () in at least one of the final zones thereof, said electrical contact () being riveted to the heating circuit ().

Filter device with a heater

A fuel filter having a filter element for filtering out particles and water from a fuel flowing through the fuel filter and having a water drainage unit for conveying filtered-out water out of the fuel filter, in which the water drainage unit is embodied as a stand-alone unit that may be separated from the filter element as needed. Also a semipermeable membrane that is permeable to water rests flat on a support. Alternatively or in addition, the water drainage unit is provided with a porous element for the evaporation of the separated water. In another embodiment two water-permeable semipermeable and hydrophilic membranes are provided. Finally, the filter element is embodied essentially in the form of a hollow cylinder in which at least part of the water drainage unit may be situated on the interior of the hollow cylinder.

An electroconductive adhesive to which a luminescent heterocyclic compound, especially a benzoxazol, is added. The ratio of the heterocyclic compound in the adhesive, which preferably is a silver-charged, epoxy-resin adhesive, is 0.01% to 0.5% by weight. The adhesive is especially suitable for bonding electrical components to circuit carriers where automated process control is employed.

Radiation&mdash;and/or heat-curable adhesive having high thermal conductivity

A method is described for producing electric modules, where a power module is attached to a fastening part with an adhesive, with the adhesive first being precured in an edge area, and in another step the power module is encased in a gel. In another step, the gel and the adhesive are fully cured together in one step. This method is cost- and time-optimized for producing a compact electric module with power modules that have a high power loss and are exposed to high mechanical stresses.
