    Abstract: PURPOSE:To provide the titled printer head of which the ink jet direction is stabilized by subjecting the same to water repelling treatment by carbon fluoride having an unsaturated bond in the molecule thereof. CONSTITUTION:A plasma polymerization film comprising carbon fluoride having an unsaturated bond in the molecule thereof is formed to the periphery of the jet orifice 5 of the jet orifice 5 of an ink particle. As carbon fluoride, C2F4, C2F2, C3F6, C4F5 or C4F6 are used and a nozzle surface may be made of glass, ceramics or a metal other than plastics. When a substrate is stainless steel, close adhesiveness is slightly poor as compared with the other substrate. Plasma gas is hardly diffused into the jet orifice with a diameter of about 50mum and the deep part of the jet orifice is not made water repellent and ink injection is not inhibited.

    Abstract: PURPOSE:To obtain a recording head having ink jet orifices whose chemical and mechanical durability is large and whose working precision is high by a construction wherein a water-repellent layer formed of a specific material is provided on a surface on which ink jet ports are formed. CONSTITUTION:The above purpose can be achieved by a construction in which a water-repellent layer formed of an amorphous material containing silicon and carbon in the main is provided on a surface 13 in which ink jet ports are formed in an ink-jetting recording head of an ink jet recording device. A surface layer composed, as the most preferable mode, of amorphous hydrogen and silicon carbide fluoride (a-Si1-xCx:H,F) which are formed by using amorphous silicon carbide as a main component and making preferably fluorine and more preferably hydrogen contained is formed on the surface 13 in which the ink jet ports are formed. The carbon content of the amorphous silicon carbide is 5-50 atom %. An amorphous state defines the state in which no crystalline portion exists in an entire material, or the state in which microcrystalline regions are scattered partly in the material.

    Abstract: PURPOSE:To provide a multinozzle plate for jetting of fluid of excellent corrosion resistance and mechanical strength and also of uniform jetting characteristics, which is obtained by providing a gold membrane on an entire surface of a multinozzle produced by anisotropic photoetching of a silicon single crystal substrate. CONSTITUTION:A multinozzle plate 1, on which a plurality of nozzles 4 are formed by anisotropic photoetching of a silicon single crystal substrate, is immersed into a fluoric acid solution to remove a thin oxide membrane, and after being washed by fresh water, a gold membrane 7 is formed on an entire surface of the nozzle plate 1 by vacuum brazing or spattering. Then, the nozzle plate 1 is put into a vacuum furnace to be heated for approximately 30min at a temperature in the neighborhood of 350 deg.C so that a eutectic alloy of gold and silicon is formed on boundary section between silicon and gold.
