摘要： A piezoelectric linear motor for providing enhanced displacement using a dome-shaped piezoelectric ceramic is provided. The piezoelectric linear motor includes a dome-shaped piezoelectric ceramic (100) processed such that different electrodes are formed on opposite surfaces of the piezoelectric ceramic. A vibration shaft (200) is fixed to a first surface of the piezoelectric ceramic so that the vibration shaft moves in conjunction with displacement of the piezoelectric ceramic. A movable element (300) is linearly driven through friction with the vibration shaft while coming into contact with the vibration shaft. The movable element moves in a movement direction of the vibration shaft if the inertial force of the movable element is less than the frictional force between the movable element and the vibration shaft when the vibration shaft moves. According to the present invention, the piezoelectric ceramic is formed in a dome shape, so that movement displacement is enhanced.

摘要： A circuit arrangement for operating a linear exhaust-gas probe has a measuring cell for measuring a gas concentration by determining a measuring-cell voltage, in addition to a pump cell for pumping gas. A comparator circuit compares the measuring-cell voltage with a target voltage and provides a corresponding analog deviation signal. A pump current source provides the pump current is controlled by the deviation signal using a control circuit for the approximation of the measuring cell voltage to the target voltage. In order to reliably limit the pump voltage with no significant detrimental effect on the operation, the circuit also comprises: a second comparator circuit for comparing the pump voltage with a predefined threshold voltage and for providing a corresponding binary switching signal; and a counter coupling path between the output of the pump current source and the control circuit, the path being enabled when the threshold voltage is exceeded.

摘要： A piezoelectric actuator is proposed, having a plurality of piezoelectric elements that are stacked on top of each other. Piezoelectric layers between each of which an inner electrode having a polarity alternating within the layer structure is provided. Outer electrodes are present at two opposing lateral surfaces, through which the inner electrodes are supplied with an electric charge. From each outer electrode at least one conductive fuse bar is directed to these inner electrodes, preferably in the inactive region, for contacting each of these inner electrodes that are associated with the polarity. The fuse bar forms an electric resistance cross-section to the respective inner electrode with the respective contact surface. In case of high current flow, the respective fuse bar blows, thus forming a fusible cut-out.
