| 20080274613 | Method for the Protection of Openings in a Component During a Machining Process - The invention relates to a method for the protection of openings in a component, produced from an electrically-conducting material, in particular, from metal or a metal alloy, during a machining process against the ingress of material, whereby the openings are sealed with a filler material before the machining process, which is removed again after the machining process. The machining processes particularly concern coating processes and welding processes. Said method is characterized in that an electrically-conducting filler material is applied, the electrical conductivity of which matches the electrical conductivity of the base material. | 11-06-2008 |
| 20100109488 | Piezoelectric Multilayer Component - A piezoelectric multilayer component has a base body with a stack of piezoceramic layers and electrode layers arranged one on top of the other in an alternating manner. Neighboring layers of the stack are braced against one another such that stresses run perpendicular to the stacking direction. | 05-06-2010 |
| 20100320876 | Piezoelectric Multilayer Component - A piezoelectric multilayer component has a stack of green piezoceramic layers arranged one on top of the other. A first electrode layer is applied onto a piezoceramic layer and contains a first metal. A structured sacrificial layer is applied onto a further piezoceramic layer, adjacent to the first electrode layer in the stacking direction, and contains a higher concentration of the first metal than does the first electrode layer. When the intermediate product is sintered, the first metal diffuses from the structured sacrificial layer to the first electrode layer and in the process leaves cavities which form a weak layer. | 12-23-2010 |
| 20110006644 | Piezoelectric Multilayer Component - A piezoelectric multilayer component includes a stack of piezoceramic layers, which are arranged one on top of the other, and electrode layers. The stack has a first area and a second area. The second area contains a disturbance material, which is used to make the second area less mechanically robust than the first area. | 01-13-2011 |
| 20110101829 | Piezoelectric Multilayer Component - A piezoelectric multilayer component includes a stack of green piezoceramic layers which are arranged one on top of the other. A first electrode layer is applied to a piezoceramic layer and contains a first metal. A second electrode layer is applied to a further piezoceramic layer and is adjacent to the first electrode layer in the stacking direction. The second electrode layer contains a higher concentration of the first metal than does the first electrode layer. | 05-05-2011 |
| 20110298337 | Piezoelectric Multilayer Component having a Disturbance Material and Method of Forming Same - A piezoelectric multilayer component includes a stack of piezoceramic layers, which are arranged one on top of the other, and electrode layers. The stack has a first area and a second area. The second area contains a disturbance material, which is used to make the second area less mechanically robust than the first area. | 12-08-2011 |
