Abstract: An electromagnetic relay, in particular a motor vehicle relay, contains a magnet yoke, a relay coil, a hinged armature which is pivotable about an axis of rotation and on which a moving contact, as working or switchover contact, is retained relative to at least one fixed contact. A piezo actuator is provided, which keeps the working or switchover contact closed when the relay coil is de-energized as a result of the actuation of the piezo actuator.

Abstract: The invention relates to a force module (20) for generating forces in a highly dynamic manner by assembling a plurality of piezo actuators (1) for connecting to a voltage source. To enable the force module (20) to generate forces in the range of a few 100 kN in a highly dynamic and spatially resolved manner, according to the invention it is proposed that the force module (20) consists of at least two sub-modules (21), each having at least two piezo actuators (1) and their electrical contacting elements, and a controlling and protection module (16) for the piezo actuators (1) in the sub-modules (21), wherein all electric contacting elements of the sub-modules (21) are fed into the controlling and protection module (16).

Abstract: Electronic short-circuiting between the anode and cathode in Li ion accumulators or batteries, an electronic separate of anode must be present with minimum electronic conductivity. To this end, in general a separating layer in the form of porous films, non-woven fabrics or nets made of polypropylene or similar polymers and containing Li ion-conducting salts and ceramic particles is used. Disadvantages of the known separating layers are the low thermal resistance and thereby embodiments with a high energy content, expensive manufacturing processes and complex interaction of the chemical substances used in the separating layers.

Abstract: A method for preparing ceramic green compacts for ceramic assemblies, especially ceramic multilayer assemblies. First, a dispersing agent solution is prepared by homogenizing a dispersing agent in a solvent mixture. Then, a binder solution is prepared by homogenizing a solvent mixture, a binder made of acrylatemethacrylate polymer and a softener. After preparing a first dispersion by homogenizing a ceramic powder and the dispersing agent solution and subsequent deagglomerization, a second dispersion is prepared by homogenizing the first dispersion and the binder solution, and subsequently removing air and highly volatile solvent components from the second dispersion.

Abstract: Co-fired multilayer piezoelectric ceramic materials with base metal electrodes based on copper, copper alloy, are found as an effective approach to manufacture low cost multilayer piezoelectrics. The method of the invention is performed at low firing temperature and without the oxidation of base metal or reduction of ceramic components. A variety of ceramic materials may be used and copper is the preferred base metal in the multi-layer piezoelectric devices of the invention. This copper has additional protection against oxidation with a small inorganic coating on the surface. With such protection, the binder and other organics can also be efficiently removed and produce superior performance in the piezoelectric structured devices.
