Abstract: A screwdriver includes a body extending longitudinally from a proximal end to a distal end. The distal end includes a distal screw engaging tip. The screwdriver also includes a slot extending through a width of the screw engaging tip and extending proximally a distance into the body. The slot permits opposed portions of the screw engaging tip to spread apart from one another into a locking configuration in which the opposed portions apply a radially outward force against an interior surface of a recess in a head of a screw into which the screw engaging tip has been inserted to releasably lock the screw engaging tip within the recess.

The reinforcement element horizontally traverses the insulation member and is connectable to the external part and the building shell.

The tensile reinforcement elements are formed as multi-part composite elements such that at least in the area of the insulating body they exhibit a central section projecting from the insulating body and at least partially being made from fiber-reinforced synthetic material.

Abstract: A connector element for installation between a building fixture component and a building, including an insulating body for creating a thermal insulation between the building fixture component and the building. The insulating body has a first edge region on the building side and a second edge region on the side of the building fixture component, and includes a force absorption element with a first extension portion arranged on the building side, and a second extension portion arranged on the side of the building fixture component. The force absorption element exerts a resistance force counter to a force emanating from the building fixture component and has a force-path characteristic which defines the resistance force in dependence on a relative movement of the building fixture component relative to the building.

Abstract: An implant comprises a deformable gas tight sack. The sack comprises a first chamber in fluid communication with an obturatable opening, the chamber filled or fillable with a filling material filling the first chamber. The implant is configured such that when one or both of a gas and fluid surrounding the filling material is removed from the first chamber through the opening, a wall of the first chamber forms around and holds the filling material. This causes the implant to transition from a relatively flexible insertion state to a relatively rigid fixation state in which the implant is fixable in the target portions of bone.

Abstract: A new high-temperature solid electrolyte fuel cell comprising an electrolyte layer between two electrode layers is obtainable by a process comprising the steps: (i) applying electrolyte particles in a screen printing paste on an unsintered electrolyte substrate and sintering the thus produced structure, (ii) depositing a nano-porous electrode thin layer by a sol-gel-process or an MOD-process on the structure obtained according to step (i) and thermal treatment of the thus coated structure. The fuel cell optionally has an electrolyte boundary layer on the structured screen printed electrolyte layer which is applied by an MOD process.

Abstract: In a gate turn-off thyristor (GTO) with homogeneous anode, emitter and stop layer, a device which short-circuit the stop layer with the anode is provided in an edge termination region. As a result, in a reverse-biased state, the GTO has a structure of a diode in the edge region and amplification of a reverse current is obviated. With this structure, thermal loading in the edge region is reduced, as the GTO tolerates a higher operating temperature at a predetermined voltage.

In a second step, the emitter efficiency of the anode emitter (2) is subsequently reduced to a desired degree by local carrier life setting.
