A piezoelectric transformer with a body that includes a first functional part and a second functional part is disclosed. The second functional part has inner electrodes, located in the body, which are connected to outer electrodes of this part. The first outer electrode of the first functional part is arranged parallel to the inner electrodes of the second functional part, wherein the minimum distance between the first outer electrode of the first functional part and the respective outer electrodes of the second functional part is selected greater than the distance between the first outer electrode of the first functional part and a terminal inner electrode of the second functional part facing it.
摘要:
A module for electrical components is proposed in which connection surfaces that can be bonded are provided on a multi-layer substrate with integrated wiring; a component chip is bonded on the top that has bond pads on its surface pointing upward and that contacts the substrate by means of bonding wires. Here, the wire guide of the bonding wires is so that they are each bonded with a ball on a connection surface and with the wedge directly on one of the bond pads.

This invention relates to a process for preparing polytrimethylene ether glycols or copolymers thereof by a polycondensation reaction using at least one acid catalyst, wherein the temperature of the reaction is controlled such that the average temperature during the first half of the reaction is higher than the average temperature during the second half of the reaction.
摘要:
This invention relates to a continuous or batch centrifugation solid-liquid separation process comprising simultaneously subjecting the solid-liquid mixture to localized magnetic field gradients and the centrifugation and to improved centrifugation solid-liquid separation processes wherein the improvement comprises simultaneously subjecting the solid-liquid mixture to a homogeneous magnetic field, a magnetic field gradient or both prior to and/or during the centrifugation.
摘要:
The current guided to the piezo actuator and the voltage which is consequently established thereon is used for calculating with the help of a non-linear actuator model, the characteristics of the longitudinal variations (s) and the force (F) exerted by the actuator (F), and variables therefrom or the derived variables (dF/dt) therefrom determine the beginning of the opening (tA) of a servovalve and the duration of injection (D).
摘要:
A method for the purification of recombinant silk proteins from a sample using magnetic affinity separation is described. The recombinant silk protein is expressed with an affinity tag which has a high binding affinity for an affinity ligand immobilized on magnetic particles. In the method, the processes of clarification of the crude silk protein extract, concentration of the product and purification of the product are combined in a single step involving the affinity capture of the spider silk protein onto the magnetic particles directly from the extract. The product yields are improved due to the reduced number of steps in the purification process.
摘要:
A ceramic material includes at least two different components. Each of the components is present in separate phases. Each of the components has a perovskite structure which contains silver in A positions and niobium or tantalum in B positions. A composition of a first component and a composition of a second component has respective permittivities TKεA and TKεB. In the ceramic material, temperature components of the permittivities TKεA and TKεB have different signs within a temperature interval.
摘要:
A method of producing a ceramic object includes producing particles of a type A and a type B. Each particle has a dimension of at least 5 μm and each type of particle includes a ceramic material that is based on a mixture of silver oxide, niobium oxide and tantalum oxide. The method includes producing a particle mixture by mixing the types of particles, producing a green compact by compressing the particle mixture, and sintering the green compact.
