摘要： Method of measuring and/or controlling flatness during rolling. The flatness deviation is measured and expressed using orthogonal polynomials. A controlled variable is generated using an Internal Mode Control by comparing the expressed deviation with values of orthogonal polynomials supplied by a model. The comparison provides a control difference to control variables that influence bending, pivoting and axial displacement of the rolls and by multizone cooling.

摘要： The embodiments relate to a piezoelectric component including at least one fully active piezoelectric element comprising electrode layers and piezoelectric layers arranged therebetween. The electrode layers are conveyed to a lateral edge of the piezoelectric element and contacted there. The external electrode is attached in a structured fashion for electrical contacting and/or a structured external electrode is made available: The external electrode essentially includes two components, namely the contacting field and the contacting path. In the event of several piezoelectric elements (piezoelectric actuator in multilayer structure) stacked one above the other, the contacting path functions as a collector electrode, which connects the contacting fields of the piezoelectric elements to one another. The insulation path exists for the electrical insulation of the contacting path from electrode layers which are not to be contacted.

摘要： Piezoelectrical bending converter with at least one monolithic layered composite, includes a piezoelectric-active ceramic layer with a lateral dimension change which may be generated by application of an electrical field and at least one further piezoelectric-active ceramic layer with a further lateral dimension change, different from the lateral dimension change. An electrode layer is arranged between the ceramic layers, for generation of the electric fields. The layered composite preferably comprises several piezoelectric-active layers and electrode layers arranged between the above. The shift is thus obtained as a gradient of the dimension changes in the direction of the stack of the layered composite. The dimension changes for the ceramic layers and the gradient may be adjusted by the generation of the electrical fields. In order to achieve a shift it is necessary not to have a piezoelectric-inactive layer.

摘要： A piezoactuator, includes at least one stacked piezoelement, with at least two electrode layers, arranged one over the other along a stacking direction of the piezoelement, at least one piezoelectric layer, arranged between two of the electrode layers and at least one pre-tensioning device, for introduction of force into a volume of the piezoelectric layer via at least one force introduction surface on the piezoelectric layer, which is arranged on at least one of the surface sections facing the pretensioning device. The force introduction surface is smaller than the surface section of the piezoelectric layer and the volume is a partial volume of the piezoelectric layer. The production of the piezoactuator is achieved by introduction of a force into the partial volume of the piezoelectric layer via the force introduction surface on the piezoelectric layer.

摘要： An additional contacting (30) for a piezoelectric component (10) is formed as a multilayer structure, wherein the piezoelectric component (10) is formed by a stack (16) of alternatingly arranged piezoelectric ceramic layers (11) and electrode layers (12, 13). The additional contacting (30) has a series of connecting elements (31) for connecting a metallization (15) of the electric component (10) to an electrical connecting element (19). In order to minimize mechanical loads during dynamic operation of the piezoelectric component (10), the additional contacting (30) is configured as an individual, structured component (32), especially in the form of a structured foil. Said structured foil (32) advantageously has a current conduction path (33) which is common to the connecting elements (31) and a contacting zone formed in the area of static base plate (17), wherein the additional contacting (30) is connected to the electrical connecting element in the area of said contacting zone.

摘要： A piezo actuator (1) is disclosed that has a contact lug (20, 21) for the electrical contacting of an electrode (14, 15) of an actuator member (11). Due to an expansion and contraction of the actuator member, a mechanical stress occurs in the contact lug that is minimized in that the contact lug has a device for adapting the expanse to a dimension of the expansion and contraction. The device is, for example, a deformation material in the form of a wire weave. The piezo actuator is utilized for the drive of an injection valve in an internal combustion engine.

摘要： The invention relates to a method for the thioetherification of mercaptanes with polyunsaturated hydrocarbons, carried out in a reactor with the addition of hydrogen, using a heterogenic catalyst and in the presence of 1-butene. The aim of the invention is to develop such a method to the extent that the creation of value from the C4 raw material stream is increased. Said aim is achieved in that the hydrogen is added to the reaction in such a manner that the molar ratio of hydrogen to polyunsaturated hydrocarbons is no more than one.

摘要： An apparatus produces electric power from mechanical vibrations at a frequency f. The apparatus provides a piezo element, which is moved by the mechanical vibration, for producing an electric AC voltage, and also an impedance matching device for matching the impedance of the piezo element to an optional rectifier. The apparatus has an electrically connected capacitive energy store and an energy user, which is connected in electrical parallel with the energy store and to which an output voltage is applied. The piezo element has an inductive element electrically connected to it such that an electric parallel resonant circuit is formed by the inductive element and a capacitance. The electric parallel resonant circuit effectively increases an electric output power for the apparatus.

摘要： A piezoelectric component with at least one fully active piezoelement has electrode layers and interposed piezoelectric layers. guided to a lateral edge of the piezoelement and contacted there. An insulating layer applied for electric contacting has an electric through-plating. An electrically conductive gas-phase deposition layer is applied directly to the electrode layer guided up to the lateral surface of the piezoelement by way of deposition from the gas phase in order to improve electric contacting. An external electrode is applied to the gas-phase deposition layer. In the case of several superposed stacked piezoelements (piezoactuator in multi-layer design), the external electrode functions as a collector electrode which connects the electrode layers to each other. The structure enables secure contacting of the electrode layers. A fully active piezoceramic multi-layer actuator with the described contacting may be used in automobile technology for activating fuel-injection valves.
