20110235276 | POWER CONVERTER MODULE WITH COOLED BUSBAR ARRANGEMENT - A power converter module with a liquid-cooled heat sink, a busbar arrangement having at least two busbars, at least two power semiconductor modules, which are mechanically connected to the liquid-cooled heat sink for thermal conduction and are electrically connected to connections of the power converter module by the busbar arrangement has at least one coolant line forming a single structural unit with the busbar arrangement. The coolant line prevents additional power loss in the laminated busbar. | 09-29-2011 |
20110249402 | POWER CONVERTER MODULE WITH COOLED BUSBAR ARRANGEMENT - A power converter module includes at least two power semiconductor modules, which are mechanically connected to a liquid-cooled heat sink and electrically connected to terminals of the power converter module by a busbar arrangement having at least two busbars. The busbars are insulated from one another by an insulation layer. The insulation layer is composed of two insulating layers, which are materially connected with one another so as to form therebetween a cavity having a predetermined shape and an entrance side and an exit side disposed on least one side face of the insulation layer. A connector is provided on the entrance side and the exit side and fluidly connected to the liquid-cooled heat sink. The rectifier module is thus able to sustain relatively high electrical loads compared to conventional rectifier modules, whilst maintaining a permitted temperature for the insulation layer and the lamination material of the busbar. | 10-13-2011 |

20150122040 | Pressure Measuring Device - A pressure measuring device, comprising: a pressure measuring cell having a measuring membrane, at least one platform and a pressure chamber formed therebetween. An electrical transducer for transducing a deflection of the measuring membrane into a pressure dependent, primary signal; a cylindrical housing having a measuring cell chamber, in which the pressure measuring cell is arranged, and an end face pressure receipt opening in communication with the pressure duct; and an electronic circuit in the housing for operating the electrical transducer, and for processing the primary signal, and for outputting a measurement signal. The cylinder axis of the pressure measuring cell forms with the cylinder axis of the housing an angle, which amounts to not less than 80°, and which is especially preferably a right angle. | 05-07-2015 |

20150135844 | Method for joining ceramic bodies by means of an active hard solder, or braze, assembly having at least two ceramic bodies joined with one another, especially a pressure measuring cell - An assembly, comprising two ceramic bodies, which are connected by means of a joint, which contains an active hard solder, or braze, wherein the active hard solder, or braze, has a continuous core volume, which is spaced from the ceramic bodies, in each case, by at least 1 μm, especially at least 2 μm, and wherein the joint has bounding layers, which border on the ceramic body. The the core volume, which includes at least 50% of the volume of the joint, is free of crystalline phases of size greater than 6 μm, especially greater than 4 μm, preferably greater than 2 μm. | 05-21-2015 |
