摘要:
The present invention relates to a device for controlling fluid movements. The device includes a fluid guiding device, and a fluid moving device which includes polymers whose hydrophilic and hydrophobic properties can be selected under the action of an external force. The fluid moving device comprises a plurality of polymer elements whose hydrophilic and hydrophobic properties can be selected. The elements are arranged along the guiding device and at least one actuating unit is used to generate the external force.
摘要:
The present invention relates to a device for moving a fluid which can be used in the ink jet printing art. The device of the present invention includes a mechanism for moving the fluid by using polymers. The polymers have hydrophilic or hydrophobic properties that can be selected under the action of an external stress.
摘要:
The invention relates to an ink reservoir for ink jet printing. This reservoir includes a solid electrolyte pellet inserted in the wall of the reservoir, which conducts O2− ions when subjected to an electric current. The reservoir allows to control the internal atmosphere of the reservoir above the free surface of the ink that it contains.
摘要:
A printing device comprising a polymer element capable of switching from an initial state to a final state when subjected to an event, the initial state and the final state being selected from an hydrophilic state and an hydrophobic state provided that the initial state differs from the second state, wherein said polymer element is impregnated with a print fluid, and a controller adapted to generate the event producing the switch of the polymer element, provided that the event is an optical, a thermal or a chemical event, wherein the controller is adapted to generate the event producing the switch of the polymer element on a localized zone and on a internal zone delimited by the localized zone, in order to form a fluid drop at the surface of the polymer element.
摘要:
The invention relates to a dressing or bandage comprising a dispersion of at least one transition metal in an imogolite or allophane matrix. In particular, it is intended for the manufacture of transparent dressings.
摘要:
The invention relates to a device for moving fluids. The invention device includes an enclosure, a solid electrolyte which can produce oxygen in the enclosure so as to distort a membrane that acts to move a fluid in an enclosure. This device is useful to produce a head for ink jet printing.
