Abstract: A slave device is provided for a clutch system of a motor vehicle, in particular a clutch slave cylinder, in the form of a concentric slave cylinder. The slave device includes a housing element having, in its interior, a pressure chamber and an annular gap arranged on the outside of the housing element wherein the annular gap is in fluid communication with the pressure chamber. A clutch system for a vehicle includes the slave device, clutch apparatus for connecting an input side to an output side, a transmission housing on the output side, and seals of the slave device lying against the transmission housing in the radial direction for sealing the annular gap.

Abstract: A process for producing a chalcogen-containing compound semiconductor includes providing at least one substrate coated with a precursor for the chalcogen-containing compound semiconductor in a process chamber; heat treating the at least one coated substrate in the process chamber, wherein during a heat treatment, a gas atmosphere comprising at least one gaseous chalcogen compound is provided in the process chamber; removing the gas atmosphere present after the heat treatment of the at least one coated substrate as a waste gas from the process chamber; cooling the waste gas in a gas processor, wherein a plurality of gaseous chalcogen compounds-present in the waste gas after the heat treatment of the at least one coated substrate are separated in time and space from one another from the waste gas by respective conversion into a liquid or solid form. Further provided is a device designed to carry out the process.

Abstract: An electric machine for use within the powertrain of a hybrid or fully electric motor vehicle includes a stator and a rotor, said stator and rotor being received in an engine housing. The engine housing has at least one A-bearing shield and at least one B-bearing shield (6) for supporting the rotor relative to the engine housing, wherein the A-bearing shield and/or the B-bearing shield has/have a multipart design, in particular a two-part design, in each case comprising a respective annular inner shield and an annular outer shield, and the inner shield is arranged radially within the outer shield such that an annular space is formed between the inner shield and the outer shield. A connection shield is at least partly arranged in the annular space so that the inner shield and the outer shield are secured in the radial direction by the connection shield.

Abstract: An electric rotation machine comprises a rotor shaft and a rotor, which is arranged on the rotor shaft, of a rotor position sensor device. The electric rotation machine additionally has a static element, on which a stator of the rotor position sensor device is arranged, and a holding element, which is mechanically fixed to the static element and which blocks the translational degree of freedom of the stator of the rotor position sensor device in a first axial direction, wherein the translational degree of freedom of the stator of the rotor position sensor device is blocked by the static component in the opposite axial direction. By virtue of the electric rotation machine, a method for producing the electric rotation machine and a drive system are provided which allow an inexpensive arrangement of the rotor position sensor device with the smallest possible required installation space and the lowest possible weight.
