The invention resides in a hydraulic cylinder (23) for a hydraulic drawing cushion (20) of a drawing press (10). The hydraulic cylinder (23) includes a first operating chamber (47), a second operating chamber (48), and a third operating chamber (53). An annular piston (45) with a first piston surface area (49) and a second piston surface area (50) separates the first operating chamber (47) from the second operating chamber (48). The first and the second piston surfaces (49, 50) have the same size. A front surface of the piston rod (33) forms a third piston surface (54) which is larger than the first and second piston surfaces. The third piston surface (54) delimits the third operating chamber (53) of the hydraulic cylinder (23). The first and the second operating chambers (47, 48) are provided for controlling the position and/or the movement of the piston rod (33). The third operating chamber (53) serves to control the metal sheet clamping force of the drawing press via the piston rod (33).

In the turbine housing for an exhaust gas turbocharger of a drive assembly at least one spiral channel, which can be coupled to an exhaust gas line of the drive assembly is provided A receiving chamber for a turbine wheel to which exhaust gas can be supplied is disposed upstream of the at least one spiral channel. The turbine wheel is disposed in the turbine housing so as to be rotatable about a rotational axis. A guide baffle is arranged fixed to the turbine housing in a transition region between the at least one spiral channel, the guide baffle being connected to the turbine housing by a metal-to-metal joint whereby the guide baffle is connected to the turbine housing in a particular tight manner.

摘要:
The present invention provides an airframe structure of an aircraft or spacecraft, with: a hollow body section which can be subjected to an internal pressure; a membrane arrangement which has at least one single-part, multi-curved membrane component for sealing off the internal pressure from an external pressure which acts on the hollow body section and differs from the internal pressure; and a joining structure for a pressure tight joining of the membrane arrangement to a region of the hollow body section; wherein the membrane arrangement forms a receiving well which is accessible from outside the hollow body section, extends at least partially into the hollow body section and is for receiving a component of the aircraft or spacecraft.
摘要:
A method of forming a field effect transistor comprising a gate formed on an insulating layer, the gate having, in a zone in contact with the insulating layer, a semiconducting central zone and lateral zones in the length of the gate, the method comprising forming a gate comprising a portion of insulating layer, a portion of semiconducting layer formed over the insulating layer, and a portion of mask layer formed over the semiconducting layer; performing an etching of the portion of the mask layer such that only a portion in the centre of the gate remains; and reacting the semiconducting gate with a metal deposited over the gate.
