Abstract: A method and a circuit for exciting an ultrasonic generator comprises a control loop which includes the ultrasonic generator itself and a voltage-controlled oscillator. The control loop keeps the active power consumption to a desired value, which is compared in a comparator with the instantaneous active power consumption. One output of a further rectangular oscillator is connected to the control input of the voltage-controlled oscillator. The rectangular oscillator is put into operation if in the control loop there are no control oscillations or only those which are smaller than a predetermined threshold. The output of the rectangular oscillator is connected across one diode to the control input of the voltage-controlled oscillator and across another diode to the controlled input of comparator. The additional signal is applied to the voltage-controlled oscillator, apart from the control signal of the control loop. The cycle of the additional signal is longer than the change time constant at the control input of the voltage-controlled oscillator and the additional signal swing is selected in such a way that the frequency of oscillator passes through a predetermined frequency range.

Abstract: The invention provides a controller (1) for a high-frequency agitation source, the controller comprising signal generation means (3) for generating a drive signal (53) having a variable duty cycle. The drive signal (53) is used to drive the high-frequency agitation source (2). The controller further comprises temperature detecting means (7) for detecting a temperature of the high-frequency agitation source (2). Further, the controller (1) is adapted and arranged to vary the duty cycle of the drive signal (53) in response to the temperature of the high-frequency agitation source (2). By varying the duty cycle of the drive signal (53), the average power supplied to the piezoelectric crystal (2) can be varied whilst still maintaining a fixed amplitude of oscillation. This allows the temperature of a high-frequency agitator, for example a piezoelectric crystal, to be controlled.

Abstract: The present invention relates to an apparatus and process for producing a thin organic film on a substrate using an ultrasonic nozzle to produce a cloud of micro-droplets in a vacuum chamber. The micro-droplets move turbulently within the vacuum chamber, isotropically impacting and adhering to the surface of the substrate. The resulting product has a smooth, continuous, conformal, and uniform organic thin film, when the critical process parameters of micro-droplet size, shot size, vacuum chamber pressure, and timing are well-controlled, and defects such as "orangepeel" effect and webbing are avoided. The apparatus includes an improved ultrasonic nozzle assembly that comprises vacuum sealing and a separate, independent passageway for introducing a directed purging gas.

Abstract: A digital processor of a nebulizer controller controls and monitors drive current (I) applied to an aperture plate. The drive current is detected as a series of discrete values at each of multiple measuring points, each having a particular drive frequency The processor in real time calculates a slope or rate of change of drive current with frequency and additionally determines a minimum value for drive current leading up to the peak value. The processor uses both the value of the minimum drive current during the scan and also the maximum slope value to achieve reliable prediction of end of dose, when the aperture plate becomes dry.
