Abstract: Method for manufacturing an electrically operable heating body for an inhaler, wherein a semiconductor material is provided so as to be substantially planar, and a plurality of channels are incorporated into the semiconductor material substantially in the direction of the surface normal of the planar semiconductor material, such that a fluid can pass through the semiconductor material in the channels.

Abstract: A cooling system having a closed cooling duct system between a main inlet and a main outlet for cooling medium, and includes at least one cooling duct section. The cooling system includes individual modular elements, each including at least one partial segment. In a connecting region of the individual modular elements, their respective at least one partial segment connect continuously to form the at least one cooling duct section. Adjacent individual modular elements each have, in the connecting region, a complementary element of a common media coupling, in which, in a detached connection between two adjacent individual modular elements, the respective partial segment contained in an individual modular element is sealed in media-tight fashion at least in its connecting region, and in a coupled connection between the adjacent individual modular elements, in the connecting region, a passage for a flow of cooling medium is opened inside the media coupling.

Abstract: A sensor device, particularly for determining the oxygen content in exhaust gases of internal combustion engines, having a sensor element that is surrounded gas-tight by a seal and fixed in a housing. The seal (19) is inserted as a pre-sintered, deformable sealing body (19') into the housing (12), between a ceramic molded body on the side of the measured gas and a ceramic molded body on the connection side (18, 20); the pre-sintered sealing body (19') can be deformed under pressure. The ceramic molded parts (18, 20) and the sealing body (19') have respective axially-extending throughgoing holes (32, 42, 52). The sealing body (19') has formed-on structures that narrow the cross section of the throughgoing hole (42) and are deformed by the sensor element (22) when the sensor element (22) is inserted such that the sensor element (22) is stopped, arrested or fixed in the installed position in the throughgoing hole (42) by the formed-on structures.
