| 摘要 |
<p>The invention relates to a method for depositing solids on a surface, by associating at least one nozzle or injector, containing at least one ejection opening, with at least one transducer, such that the activation of the transducer, which is in contact with any of the surfaces of the injector, produces an oscillating and vibratory movement in relation to the surface of the injector containing the ejection opening, in such a way that a powdered or granulated solid material, located inside same, is projected through the lower portion of the nozzle or injector via the opening in the injector and in a direction (z) perpendicular to the plane in which said opening is located, such that the material is deposited on a surface located below the injector.</p> |
