    摘要: A printing apparatus having a printing head that prevents ink, diluent, and a mixed solution thereof from adhering to and spreading about a portion of the printing head around a nozzle. The printing apparatus has an enhanced ability to reproduce a gradation of concentration, thereby making it possible to form a recorded image of high resolution. The printing head has a first nozzle, which discharges a discharge medium, and a second nozzle, which discharges a metering medium. The orifices of the first and second nozzles are adjacent to each other in a nozzle outlet face of the printing head. A groove, a hydrophilic portion, or an insular projection is formed between the first and second nozzles to control the spread of ink, diluent, and a mixed solution thereof around the nozzles. The hydrophilic portion may be made by a non-processed portion of the outlet face of the printing head, and a portion other than the nonprocessed portion may be made a hydrophobic portion. Several variations of the groove, hydrophilic portion, and insular projection are disclosed.

    摘要: A method of manufacturing a printing head which can prevent ink, diluent, and a mixed solution thereof from adhering to and spreading about a portion of the print head around the nozzle is disclosed. The method comprises forming a hydrophobic film on a surface of a nozzle member, forming a first nozzle into which a discharge medium is introduced, and a second nozzle into which a metering medium is introduced, in the nozzle member. The first nozzle has a first orifice on the surface, and the second nozzle has a second orifice also on the surface. The first and second orifices are located so as to ooze the metering medium from the second orifice to the first orifice through the surface. An additional step of removing the hydrophobic film from a portion of the surface between the first and second orifices to define a groove is included.

    摘要: A radial line slot array antenna has a slotted conductor plate in which a plurality of slots are formed and arranged in a spiral. The plurality of slots are arranged in the slotted conductor plate such that the arrangement distance in a radial direction between the slots varies gradually between a first portion determined based on a first frequency and a second portion determined based on a second frequency that is different from the first frequency.
