Patent number: 11205610Abstract: The present disclosure relates to components, such as base bodies, for feed-through elements including a metallic base body, at least one through-opening for receiving a functional element in a fixing material, such as an electrically insulating fixing material, and at least one conductor, which is connected electrically conductively to the base body by a soldered connection. The soldered connection includes a metallic solder material that covers a surface region of the base body and thus forms a soldering region on a surface of the base body. The base body has, at least in the soldering region, a microstructuring that includes at least depressions in the surface of the base body. The present disclosure similarly relates to methods for producing such base bodies and to applications thereof.Type: GrantFiled: September 25, 2018Date of Patent: December 21, 2021Assignee: Schott AGInventors: Helmut Hartl, Reinhard Ranftl

Publication number: 20140152977Abstract: A sensor component for an optical flow rate sensor for fluid and/or gaseous media includes at least one component segment and at least one sensor segment. The sensor segment includes at least two inspection windows in the region of a plurality of cutouts in a sensor segment disposed such that it is possible for light to pass through a transverse section of the sensor segment. The sensor segment may include exactly one inspection window in the region of a cutout and a reflective surface, for example a mirrored or polished surface, provided on the side opposite the cutout, such that it is possible for light to pass through the sensor segment twice through a transverse section of the sensor segment. The sensor component includes a receiving component that can be inserted in the one or more cutouts and the sight glass is bonded to the receiving component.Type: ApplicationFiled: November 21, 2013Publication date: June 5, 2014Applicant: SCHOTT AGInventors: Reinhard Ranftl, Helmut Hartl
