In an integrated optical lightguide device including a light-transmitting core layer, an inclusion or buffer layer, and an active or cladding layer. The cooking cavity is open at a front thereof. Film extends from the supply at the lower longitudinal side of the application member facing the substrate during the mode of operation to an application edge of the application member running transversely at the front end. The receiver output can also serve as a predetermined potential when the resistive element has a long time constant compared to the data rate or the resistive element is non-linear. The loudspeaker assembly of the present invention can be mounted in any orientation. A processing chamber receives a substrate subjected to a processing with supercritical fluid, and a liquid supply unit supplies a processing liquid including a fluorine compound to the processing chamber.
