Abstract:
In an ink jet printer head which ejects ink drops from a nozzle (11) formed on the surface of the nozzle plate 1, wherein a metal layer (13) and a sulfur compound layer (14) are formed on the surface of the nozzle. Gold atoms of the metal layer (13) and sulfur atoms of the sulfur compound layer (14) are bonded covalently and form a water repellant thin film. Since ink does not remain on the nozzle surface, problems such as ink drops being pulled by residue ink and the ejection direction of ink drops being bent are eliminated.

PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid droplet jet head, in which a nozzle is formed of a molding material by using a metallic mold excellent in durability, and a high shape reproducibility is obtained, and which is less in the variation of a liquid droplet jet amount. SOLUTION: Instead of a stage for forming a liquid droplet jet head by forming a straight part 221 in the metallic mold 211, a stage for forming the straight part by anisotropic etching is used. Namely, it is unnecessary to form a metallic mold equipped with a thin straight part which requires technique for processing with very high difficulty. Therefore, the nozzle is formed of the molding material by using the metallic mold excellent in durability. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To provide a liquid drop discharging apparatus which can discharge ink of different concentration onto a prescribed substrate. SOLUTION: The substrate conveyed by a belt conveyor BC driven by a driving device 16 based on a signal from a controller 14, for example the substrate on which a segment electrode is formed, is washed in a washing device 4. Onto the substrate conveyed by the belt conveyor BC, a plurality of nozzle rows formed on a nozzle forming face of an discharging device 6 discharge alignment film material having different concentration and different amount for different nozzle rows. Then, temporary drying of the alignment film material applied onto the substrate is performed in a drying device 8 and the substrate is baked in a baking device 10 to form an alignment film. Further, rubbing treatment is applied to the alignment film in a rubbing device 12. COPYRIGHT: (C)2006,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a liquid drop weight measuring instrument for measuring precisely a weight of a liquid drop delivered from a delivery head, and a liquid drop delivering device. SOLUTION: A QCM sensor 106 is constituted of an electrode 110a, an electrode 110b, and a quartz oscillator 110 with the electrode 110a and the electrode 110b on both faces. A measuring part 112 detects, as the first resonance frequency, a resonance frequency of the quartz oscillator 110 before the liquid drop delivered from the delivery head 103 is deposited on the electrode 110b, and detects a resonance frequency of the quartz oscillator 110 after the deposition, as the second resonance frequency. The measuring part 112 measures the weight of a liquid drop deposited to the electrode, based on the first resonance frequency and the second resonance frequency. A control part 101 controls the execution of weight measurement for the liquid drop, so as to execute the weight measurement for the liquid drop when the first resonance frequency is not within the first prescribed range, and to execute the weight measurement for the liquid drop when the first resonance frequency is within the first prescribed range.
