    摘要: A printhead which comprises a body with pressure chambers (13) and nozzles (14), a membrane (17) connected to the body so as to form one wall of the pressure chambers, and an actuator plate (25) comprising an actuator element (31) for each pressure chamber. A support plate (19) between the actuator plate and the membrane includes first portions (21) and second portions (23) with the first portions being movable relative to the second portions in the direction of the thickness of the support plate, a first portion being situated between each actuator element and the corresponding pressure chamber. The actuator plate has active regions (31) and inactive regions (33), the actuator elements being formed by active regions of the actuator plate. Adjacent actuator elements are separated from each other over substantially their whole length by slits (35) in the actuator plate. The actuator plate can be a ceramic multilayer actuator (CMA).

    摘要: The invention concerns a method of producing a surface layer structure by doping a matrix with metal ions. The aim of the invention is to provide a method of this kind in which the depth distribution of the metal ions in the substrate can be regulated, thus optimumizing the doping without incurring any of the disadvantages inherent in the prior art methods. This is achieved by first depositing matrix material on a suitable substrate by laser ablation in an atmosphere of oxygen, thus forming a on surface of the substrate a first layer a matrix material. Dopant is then deposited on the surface of the first layer, followed by more matrix material. The result is a uniform doping of the deposited matrix at a defined depth in the surface layer structure.
