摘要:
The invention concerns a device for air/water extraction by semi-humid electrostatic collection, comprising a chamber (7) containing a discharge electrode (1) for generating an ion flow from an ionized gas accumulation surrounding the discharge electrode (1) and a counter-electrode (2), an inlet (3) for mixing air and aerosol to be extracted which contains liquid or solid particles, a steam supply tube (8) and an outlet (4) for cleansed air. The invention is characterized in that the device enables stream to be introduced through said steam supply tube (8) in the gap between the discharge electrode (1) and the counter-electrode (2) so as to form a steam sheath (10) enclosing the discharge electrode over its entire length, such that the treated air is not steam-saturated.
摘要:
The method for controlling the downstream progress of a liquid in a microfluid component, comprising, for example, a number of microchannels, each having a number of successive reaction or detection zones and a number of passive valves, controls the progress of the liquid in the microchannels by controlling the increase of pressure differential between the upstream and downstream end of the component. The method controls the increase in pressure differential in a discontinuous manner in the form of release pulses (Pd), such as to particularly synchronise the passage through the corresponding passive valves in the microchannels. The pressure difference is reduced to a zero value between two successive release pulses (Pd).

摘要:
A device for vapour-depositing a material on a substrate (112), characterised in that it comprises a housing in which n sources (44, 46) for vaporising the material are provided, and means for directing, during vaporisation, the vapour emitted by said sources to the substrate, said means being formed by walls (59) or screens defining compartments within the housing, each vaporisation source (44, 46) being arranged in one compartment. The device may also contain means for moving the substrate for a more regular deposition.
摘要:
L'invention concerne un dispositif de déplacement d'au moins un petit volume de liquide (5) sous l'effet d'une commande électrique, comprenant un substrat (1) pourvu de premiers moyens électriquement conducteurs (2), le dispositif comprenant également des deuxièmes moyens électriquement conducteurs (3) disposés en vis-à-vis des premiers moyens électriquement conducteurs (2), les premiers moyens électriquement conducteurs et les deuxièmes moyens électriquement conducteurs pouvant être reliés à des moyens d'alimentation électrique pour permettre l'application de forces électrostatiques au petit volume de liquide (5). Les deuxièmes moyens électriquement conducteurs comprennent au moins un fil conducteur (3) disposé parallèlement au substrat et à une distance déterminée du substrat pour permettre le déplacement du petit volume de liquide (5) le long dudit fil conducteur (3) sous l'effet des forces électrostatiques appliquées.
