    Abstract: A vibration device includes a cylindrical body including a cavity, a first opening end surface, and a second opening end surface, a light-transmissive cover directly or indirectly bonded to the first opening end surface of the cylindrical body so as to cover the cavity of the cylindrical body, a piezoelectric body directly or indirectly bonded to the cylindrical body, and a buffer layer provided between at least one of the cylindrical body and the piezoelectric body, and the cylindrical body and the light-transmissive cover. The buffer layer includes an inner end portion on an inner side portion in a direction orthogonal or substantially orthogonal to the axial direction and an outer end portion on an outer side portion in a direction orthogonal or substantially orthogonal to the axial direction. A thickness of the inner end portion is larger than a thickness of the outer end portion.

    Abstract: A compact apparatus for atomisation of fluid samples comprises a sonotrode (11), placed so that an ultrasonic wave emitted by the sonotrode is directed through a channel (25) in a separate channel device (21) and reflected by from the interface (26) in a high-low impedance transition zone (Tz), so that a standing wave is formed within the channel. A positive air flow through the channel, driven by a pressure differential at each end of the channel, interacts with the working fluid or slurry being delivered by a fluid delivery device (30) to atomise it. The speed of the air flow and the dispersal, homogeneity, and size of particles in the slurry sample can be controlled by varying the shape of the channel outlet.

    Abstract: A driver circuit for driving, for example, ultrasonic transducers in medical equipment, such as ultrasound scanning equipment. The driver circuit includes first inputs receptive of a pulsed signal, second inputs receptive of an analog signal, an output for applying a pulsed drive signal or an analog drive signal to a load. A pair of output transistors of complementary polarities are positioned with their current paths in series between opposing supply lines with a connection point intermediate between the transistors of the pair of transistors. The connection point between output transistors is coupled to the output of the circuit. The control terminals of the output transistors, which are coupled together, may be coupled to the first inputs with the driver functioning as a pulser, or else coupled to the second inputs with the driver functioning as a linear driver.

    Abstract: The invention provides an ultrasonic nebulizer comprising a circuit unit, a nebulization module, and a frequency sweeping unit. The invention utilizes the technique of maintaining constant electric power in the nebulization module of the ultrasonic nebulizer by automatic compensation of electric power consumption and/or current consumption. Using such a technique, the invention allows a fixed current consumption and electric power consumption of a nebulization module of an ultrasonic nebulizer by auto compensation, thereby improving nebulization performance.

    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 “orange peel” 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.
