Publication number: 20140343648Abstract: One aspect relates to a contacting arrangement for use in a housing of a medically implantable apparatus. Said contacting arrangement includes an electrical feedthrough device that includes at least one electrically insulating main feedthrough member and at least one electrical conducting element. The conducting element is designed to establish at least one electrically conducting connection between an interior of the housing and an exterior through the main feedthrough member. The conducting element is hermetically sealed with respect to the main feedthrough member. The at least one conducting element comprises at least one cermet. The contacting arrangement further includes an electrical filter structure which is arranged on a face of the feedthrough device. Furthermore, said filter structure is connected to the conducting element by means of at least one electrical surface connection.Type: ApplicationFiled: November 13, 2012Publication date: November 20, 2014Inventors: Heiko Specht, Andreas Reisinger, Goran Pavlovic, Christina Modes, Frieder Gora, Frederik Roth

Patent number: 7030050Abstract: The invention relates to a glass ceramic mass containing at least one oxide ceramic containing barium, titanium and at least one rare earth metal Rek; and at least one glass material containing at least one oxide with boron, at least one oxide with silicon and at least one oxide with at least one bivalent metal Me2+. The glass ceramic mass is characterised in that the glass material contains at least one oxide with bismuth, especially bismuth trioxide. The oxide ceramic is especially a microwave ceramic of formula BaRek2Ti4O12, Rek being neodymium or samarium. The composition of the oxide ceramic remains essentially constant during the sintering of the glass ceramic, enabling the material properties of the glass ceramic mass, such as permittivity (20–80), quality (800–5000) and Tkf (±20 ppm/K) to be specifically predetermined. The glass ceramic mass is characterised by a densification temperature of under 910° C.Type: GrantFiled: August 31, 2001Date of Patent: April 18, 2006Assignees: Bundesanstalt fur Materialforschung und - prufung, W. C. Heraeus GmbH & Co. KGInventors: Oliver Dernovsek, Markus Eberstein, Ulrich Fritz, Marion Gemeinert, Christina Modes, Gabriele Preu, Wolfgang Arno Schiller, Wolfram Wersing

Publication number: 20040014584Abstract: The invention relates to a glass ceramic mass, comprising at least one oxide ceramic, containing barium, titanium and at least one rare earth metal Rek and at least one glass material, containing at least one oxide with boron and at least one oxide of a rare earth metal Reg. The glass material further contains either an oxide of a tetravalent metal Me4+, or at least one oxide of a pentavalent metal Me5+. A compression of the glass ceramic mass occurs above all by viscous flow. A low vitrification temperature can thus be achieved. Crystallisation products are produced during and/or after the compression. The rare earth oxide and the crystallisation products can be used to pre-determine each of a dielectric material property of the glass ceramic mass in a wide range such as permittivity (15-80), Q (350-5000) and Tf value (±20 ppm/K). The glass ceramic mass is characterised by a vitrification temperature of below 850° C.Type: ApplicationFiled: August 5, 2003Publication date: January 22, 2004Inventors: Oliver Dernovsek, Markus Eberstein, Wolfgang Guther, Christina Modes, Gabriele Preu, Wolfgang Arno Schiller, Barbel Schulz, Wolfram Wersing

Publication number: 20020175076Abstract: A laminated assembly having a first layer, a second layer, and at least one sintered insulating film for electrical insulation of the first layer from the second layer. The first layer is one of a first solid electrolyte layer that conducts oxygen ions and a first electrically conducting layer. The second layer is one of a second solid electrolyte layer that conducts oxygen ions and a second electrically conducting layer. The insulating film is formed on a substrate using a paste or a suspension produced from at least one of a ceramic powder and a glass powder. One of the first layer and the second layer serves at least partly as the substrate. The sintered insulting film has a thickness ≦10 &mgr;m, and the powder is a nanoscale powder with a BET specific surface >50 m2/g and a maximum particle size of 100 nm.Type: ApplicationFiled: April 24, 2002Publication date: November 28, 2002Inventors: Frieder Gora, Stefan Malkmus, Christina Modes, Annette Kipka
