    摘要: The invention relates to a method for provision of a drive signal for a switch which controls the current drawn by an inductive energy storage element in a power factor correction circuit in which a control signal which controls the power consumption is available. One drive cycle of the switch comprises: detection of a predetermined storage state of the inductive energy storage element; when the predetermined storage state of the storage element is detected, production of a switching-on level for the drive signal for a regular switched-on duration which is dependent on the control signal or for a maximum switched-on duration which is dependent on an input voltage, when the regular switched-on duration is greater than the maximum switched-on and production of a switching-off level for the drive signal for a switched-off duration until the next detection of the predetermined storage state.

    摘要: A device is proposed for holding an electric motor which has a tubular housing portion enclosing the motor armature and supports which are associated with the motor housing are arranged at the end sides of the housing portion for the arrangement of bearings for the motor shaft. The motor is held in such a way that vibrations are minimized and noise is damped in that at least one resilient damping member is arranged between the inner walls of the holding device and the outer walls of the motor housing facing these inner walls. The damping member is supported at the walls of the holding device and motor housing which face one another.

    摘要: A sensor according to the invention has an amplifier that is capacitively loaded vis-à-vis the ground by a container and by a medium contained therein and that has a capacitive feedback that is dimensioned in such a way that the amplifier only oscillates when the critical filling level has not been reached. According to the invention, the capacitive feedback is influenced by the container in such a way that the capacitive load of the amplifier input caused only by the container is countered. In this manner, it is achieved that the sensor responds only to the capacitance of the medium, largely independently of the magnitude of the container capacitance. A sensor according to the invention is also characterized by such an operating frequency that, on the basis of the conductivity of the medium, it is possible to distinguish between a massive and an apparent filling of the container with the medium simulated by wetting or foam formation, but it largely avoids those problems encountered with sensors having a very high operating frequency of more than 50 MHz.
