摘要： A piezoelectric actuator(6) is disclosed, wherein a superposing pulse is generated just after a command pulse falls to thereby reduce oscillations of displacement in piezoelectric elements(7). In the piezoelectric actuator(6), an exciting pulse having a preselected pulse width is applied across terminals of the piezoelectric elements(7) to cause strains in dimension for the piezoelectric elements(7). A pulse is superposed such that it is superposed at a timing a at which the exciting pulse is turned on, and then the exciting pulse is once turned off for a minute length of time, or an interval between b and b', and turned on again at c. The pulse to be superposed is supplied with a timing less than one-fourth a period of an oscillation of the piezoelectric elements(7). The piezoelectric actuator(6) is effective to prevent the resonance phenomenon and preferably employed for the fuel-injection apparatus.

摘要： Energy (E) is supplied to a capacitive actuator and the actuator voltage (Up) at the actuator is measured. A conclusion on the state of operation of the actuator or an injection valve, for example its defective or correct operation, is drawn from the energy (E) and the comparison between the actuator voltage (Up) and reference values (Bo; Bu). An actuator lift (ds) is also derived from the actuator voltage (Up). The process is based on regularities represented in a diagram by actuator characteristic curves (KL I; KL II).

摘要： The present invention relates to a method and a device for determining the temperature of a piezo-electric element. This method and this device can be used for determining the capacity of a piezo-electric element at a desired temperature as well as for determining the desired temperature of the piezo-electric element on the basis of both the determined capacity and the capacity variability relative to the temperature. This method and this device can therefore be used for easily determining the temperature of the piezo-electric element without influencing the function thereof.

摘要： When activating a capacitive actuator, including for a fuel injection valve, the load of a capacitor loaded in relation to a prescribed voltage is transferred, at least partly, during a given loading period to the actuator; the deviation between the energy transferred to the actuator and the curve established on a trial basis, which represents a set constant energy level for the whole range of temperatures of said actuator, is incrementally corrected during the following activation operations.

摘要： There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the piezoelectric actuator is at first given a voltage of inverse polarity, for generating a displacement in an opposite direction, and then given a voltage of forward polarity, for generating a displacement in the normal functioning direction, thereby actuating the mechanical system. Displacement and acceleration become larger, as the displacement of the actuator takes place from a position in the inverse direction.

摘要： There is disclosed a driving device for piezoelectric actuator, in which a voltage is applied to a piezoelectric actuator to generate a mechanical deformation therein, thus actuating a mechanical system. In an aspect, the electrical insulation state of the piezoelectric actuator is detected, and, if deteriorated, the destruction of insulation is prevented by an alarm generation and/or inhibition of voltage application. In an embodiment, the insulation state is identified from the ambient humidity of the actuator. In another aspect, if the detected humidity is at a high level that may induce destruction of insulation, the piezoelectric actuator is driven with a low voltage, in order to dehumidity by heat generation. Also shutter control devices for camera, utilizing piezoelectric actuator, are disclosed.

摘要： A vibratory feeder for sheets includes sheet conveying members (3,4) for holding and conveying the sheet utilizing travelling waves, a sheet feed detection member (102) for detecting a feed of the sheet, and a drive control circuit (101) for applying an alternating electrical signal to each of electric/mechanical energy conversion elements on the basis of the sheet feed detection information from the sheet feed detection member. The travelling wave is formed in each of the sheet conveying members by applying the alternating electric signal controlled by the drive control circuit to each of the electric/mechanical energy conversion elements, by which a conveying force is applied to the sheet. The drive control circuit feeds the sheet in the following manners on the basis of the sheet feed detection information from the sheet feed detection member. The sheet is fed first at a fixed high speed until it has been fed to a position close to the desired distance. Thereafter, feeding of the sheet is temporarily suspended, and then the sheet is fed stepwise until it reaches the desired position.
