摘要:
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.

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.
摘要:
A reinforcing element for concrete construction in the form of a set bolt which is formed of a rod-shaped section with a cross-sectional enlargement on the end is provided. Significantly, at least this cross-sectional enlargement is formed of glass-fibre reinforced plastic and has an axial bore in its centre, and that the bore and the area of the rod-shaped section surrounded by it engage with one another in a form-locking manner.

A reinforcing rod made from fiber-reinforced plastic is provided on its peripheral surface with profiling projecting outwardly in the radial direction in the form of ribs extending at least across one part of the periphery. The reinforcing rod has ribs with different geometric and/or material properties.

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.

A two-stage method is proposed for producing a highly transparent anode emitter (2) in a GTO (1). In a first step, an anode emitter (2) is indiffused whose thickness is greater than 0.5 .mu.m and whose doping concentration is greater than 10.sup.17 cm.sup.-3. In a second step, the emitter efficiency of the anode emitter (2) is subsequently reduced to a desired degree by local carrier life setting.
