Abstract: The present invention relates to an airfoil for a gas turbine, including an improved turbulator arrangement formed on an inner cooling channel of the airfoil. According to preferred embodiments of the invention, in order to ensure a constant angle of the cooling flow inside the channel relative to each turbulator, the angle formed between the turbulator and the vertical axis is advantageously adapted, in the curved area, for every single turbulator. Furthermore, the same principle may be applied to all the cooling channels present within the airfoil.

Abstract: A method for operating a fuel cell system for the provision of electrical power is provided. The fuel cell system is disconnected when control electronics detect a fault. The fault that led to the disconnection is evaluated by the control electronics. An automatic restart of the fuel cell system through the control unit occurs if the evaluation of the fault permits this.

Abstract: The invention relates to a method of manufacturing a semiconductor device (10) with a substrate (11) and a semiconductor body (12) comprising silicon which is provided with at least one semiconductor element (T), wherein an epitaxial semiconductor layer (1) comprising silicon is grown on top of a first semiconductor substrate (14), wherein a splitting region (2) is formed in the epitaxial layer (1), wherein a second substrate (11) is attached by wafer bonding to the first substrate (12) at the side of the epitaxial layer (1) provided with the splitting region (2) while an electrically insulating region (3) is interposed between the epitaxial layer (1) and the second substrate (11), the structure thus formed is split at the location of the splitting region (2) as a result of which the second substrate (11) forms the substrate (11) with on top of the insulating region (3) a part (IA) of the epitaxial layer forming the semiconductor body (12) in which the semiconductor element (T) is formed.

Abstract: A method of welding two work pieces that define a connecting zone between them is described. A friction pin is fed at a starting point into the connecting zone and into opposite regions of the work pieces on both sides of the connecting zone. The friction pin is moved in a welding direction along the connecting zone resulting in the work pieces being welded. The friction pin is led out of the connecting zone after welding the work pieces. The friction pin is fed into a sacrificial element while lifting the friction pin.
