摘要： The invention relates to a module (1) in which voltages greater than 1,000 V and currents greater than 100 A are applied via supply lines, with an electrically insulating carrier (2), with a connection means (3) which has a material thickness greater than 0.3 mm and is connected to the carrier (2) via a metallization area (4) which is delimited by a first end (23) and a second end (24), with electronic components (19, 20) which are connected to the connection means (3) as required, and with cooling means (14).
In order that the power is supplied from the outside via the connection means (3) directly to the module and thus the bonding processes that are customary in the prior art are omitted and parasitic inductances on the power supply are avoided, the invention proposes that the connection means (3) protrudes beyond one end (23, 24) of the metallization area (4) at least at one point, is not fixed to the carrier (2) in this area (9) and has contact means (22).

摘要： A component (9) includes a first ceramic substrate (1), a ceramic fin cooler or a ceramic cooler through which liquid flows, having an upper face (1b) and a lower face (1a). A metallization (2) is applied to the upper face (1b), on which metallization a circuit (4) is mounted by its lower face. The circuit (4) of the component (9) is cooled on both sides by elements having high thermal conductivity and at the same time high electrical conductivity and thus the efficiency of the assembly is increased. A ceramic electrical/thermal conduction substrate (6) is attached by its lower face to the upper face of the circuit by a connection, and a second ceramic substrate (8) is arranged on the upper face of the electrical/thermal conduction substrate (6) via a metallization (7). The substrate (8) contains metal-filled thermal-electrical vias (11) and/or cooling channels to guide a coolant.

摘要： The invention relates to a knee endoprosthesis comprising a femoral component (1) which has two condylar surfaces (1a, 1b) for anchoring on the distal femur, comprising a tibial component (2) for anchoring on the proximal tibia, and comprising sliding surfaces between the two components (1, 2). It is proposed according to the invention that the entire femoral component (1), but at least its condylar surfaces (1a, 1b) are made of a solidly sintered ceramic for articulation with the tibial component (2), so that the knee endoprosthesis will have the least possible amount of abrasion with optimal reproduction of the anatomical and kinematic properties of the natural knee joint, in particular through suitable combinations of materials and by reducing the abrasion-generating surfaces. This is achieved by the fact that the tibial component (2) comprises a tibial baseplate (11) made of a solidly sintered ceramic which has a medial spherical bearing shell (7) on the upper face of the baseplate facing the femoral component (1). The medial spherical bearing shell (7) is an integral component of the tibial baseplate (11) and is formed in one piece with it, and the articulation surface of the medial femur condyle (1a) is also designed to be spherical, and together with the medial spherical bearing shell (7), forms a congruent ball joint. Laterally adjacent to the medial spherical bearing shell (7), a bearing shell (8) which enables rotation of the femoral component (1) and is formed by multiple radii in the anterior-posterior direction is arranged non-congruently with the femoral condyle (1b) and is either formed integrally with the tibial baseplate (11) or is an inlay that is movable relative to the tibial baseplate (11).

摘要： A sintered molded article includes a ceramic of α/β-sialon having a grain boundary phase, the grain boundary phase containing at least one hard material formed in situ as an additional phase. A method for the production of the sintered molded article uses at least the following compounds as a starting material: Si3N4, AlN, and, if applicable, Al2O3, at least one oxide of the rare earths, and at least one oxide of the element titanium.

摘要： The invention relates to a carrier tool (1) comprising a clamping element (2) with a clamping element projection (3) and comprising a cutting insert (4) with a clamping recess (5) on the cutting insert surface (13) for machining workpieces. The clamping recess (5) has an annular indentation (9) with a recess base (7), and the indentation (9) transitions from the recess base (7) into the cutting insert surface (13) via an annular surface (8). The indentation (9) surrounds an elevation (10), the tip (11) of which lies above the recess base (7) and below the cutting insert surface (13). The clamping element projection (3) engages into the clamping recess (5) and thus clamps same on the carrier tool (1). In order to allow a pre-centering of the contour of the clamping element projection (3) and the contour of the clamping recess (5) when closing the clamping element (2), the contours of the clamping element projection and the clamping recess thus engaging into each other in a form-fitting and precisely positioned manner, the clamping element projection (3) has an annular contour (12) which surrounds the elevation (10) in the clamped state but does not contact the elevation and rests solely on the annular surface (8).

摘要： The invention relates to a piezoceramic sensor in a housing having a layer (3), preferably a PZT layer, made of a piezoelectric material, on both sides of which there is a respective sensor electrode (2), both sensor electrodes (2) being connected in each case to a pole (5, 6). In order that no potential difference, which would allow for the charge to be dissipated by way of the surface, is formed between the housing and the sensor electrodes (2), it is proposed according to the invention that the layer (3) protrudes beyond the sensor electrode (2) on at least one side of the layer (3), and a protective electrode (1) which encompasses the sensor electrode (2) at an insulating distance (7) is arranged on that part of the layer (3) which protrudes beyond the sensor electrode (2).
