A carrier housing for a turbocharger arrangement to be fastened at an internal combustion engine includes first, second and third fastening flanges for fastening to turbines of a respective one of a high-pressure turbocharger, a first low-pressure turbocharger, and a second low-pressure turbocharger. The cup is secured to a motor faceplate, within a recess formed in the faceplate by interference fit, or by means of a clamp attached to the faceplate. The metallic member is permanently secured to a hidden surface of a tub at a location corresponding to a desired location of the cushion on the exposed surface of the tub. An asynchronous communication server system is connected to the proxies. A periodically doped conduction layer is formed on the active layer. Also disclosed is a passage in the frame.
