Abstract: A frothing device (1) is disclosed which is suited for a beverage machine. The frothing unit has an inlet (11) for a frothing medium (12) and a gas inlet (13) with an opening diameter. Furthermore, the frothing unit comprises a pumping means (14) and a tubing (15) for connecting the aforementioned components to one another. The aforementioned components form a continuous tubing system. In addition, due to the pumping action of the pumping means, a negative pressure difference with respect to the atmospheric pressure is accomplished throughout the whole tubing system.

Abstract: Semiconducting device and method of manufacturing a semiconducting device in which organic thin film transistors (TFTs) and other components are fabricated on a substrate (206), using a hybrid technology of lithographic and printing steps. A lithographically defined resist pattern (211, 311) provides barriers and cavities which serve to guide subsequently printed materials. Different components of the integrated circuitry form separate islands on the substrate (206). The risk of adjacent films cracking and peeling from stress is reduced. The flexibility of the device is increased.
