An explosion-proof housing includes at least one metal housing part having at least one of a housing opening or receiving surface, and a support edge bordering said at least one of a housing opening or receiving surface. A cover part covers said at least one of a housing opening or the receiving surface. The cover part includes a peripheral cover edge which is connected to the support edge in an explosion-proof manner such that in the event of an explosion inside the housing, the explosion is prevented from crossing over to an explosive atmosphere surrounding the housing. A plurality of connection points are formed between the support edge and the cover edge. The connection points include interlocking depressions and protrusions. The protrusions are formed by partial melting of the cover edge. The depressions and the protrusions interlock with play in a longitudinal direction of the housing.

There is provided a method for producing a metal-resin composite which includes a resin member and a metal member having a roughened surface in at least a portion of the surface thereof, the resin member being joined so as to be in contact with at least a portion of the roughened surface. The method includes a step of joining the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The method includes making adjustment so that when the roughened surface is measured at arbitrary five points by using a confocal microscope according to ISO 25178, the developed area ratio (Sdr) is 5 or more in terms of number-average value.

An elongate medical device having an axis comprises an inner liner, a jacket radially outward of the liner, a braid comprising metal embedded in the jacket, a sensor, and at least one wire electrically connected to said sensor. The at least one wire is one of: embedded in the jacket and optionally disposed helically around the braid; extending longitudinally within a tube which extends generally parallel to the device axis and wherein the tube is embedded in the jacket; and disposed within a lumen, wherein the lumen extends longitudinally within the jacket.

A method for producing a frame component for a door frame structure of an aircraft. A connecting zone is generated on a first and a second assembly surface of a connecting component in each case by generating a surface texture on the assembly surfaces, wherein the connecting component is formed from a metal material. The assembly surfaces of the connecting component are placed against a door frame member and against an attachment member, wherein the door frame member and the attachment member are each formed from a fiber-reinforced thermoplastics material. Furthermore, the connecting component and the door frame member are welded, and the connecting component and the attachment member are welded. A frame component and a door frame structure are also described.
