    摘要： An ink jet head comprises a plurality of discharge pressure generating elements serving as the discharge pressure source for discharging an ink droplet, an orifice plate having a plurality of ink discharge ports corresponding to the respective discharge pressure generating elements formed therefor, an ink supply port for supplying ink and a nozzle wall forming an ink flow path communicating the ink discharge ports with the ink supply port. The orifice plate and the nozzle wall are formed by resin material, and also, a thin metallic film is formed on the outer surface of the orifice plate. If desired, a water-repellent film is formed further on the surface of the thin metallic film. With the metallic film formed on the surface of the orifice plate, the moisture in ink is effectively prevented from being evaporated. Further, with the provision of the metallic film, it becomes possible to perform the eutectoid plating for the formation of the water-repellent film. With the head thus structured, it becomes possible to stably obtain excellent print quality.

    摘要翻译： 喷墨头包括用作排出墨滴的排出压力源的多个排出压力产生元件，具有与其形成的各个排出压力产生元件对应的多个排墨口的孔板，用于 供给墨水和形成将墨水排出口与供墨口连通的油墨流路的喷嘴壁。 孔板和喷嘴壁由树脂材料形成，并且在孔板的外表面上形成薄金属膜。 如果需要，在薄金属膜的表面上进一步形成防水膜。 通过在孔板的表面上形成金属膜，有效地防止油墨中的水分蒸发。 此外，通过设置金属膜，可以进行用于形成防水膜的共析电镀。 通过这样构造的头部，可以稳定地获得优异的打印质量。

    摘要： A liquid ejection method includes a step of preparing a liquid ejection head including an electrothermal transducer element for generating thermal energy contributable to ejection of liquid, an ejection outlet for ejecting the liquid, the ejection outlet being provided at a position opposed to the electrothermal transducer element, and a liquid flow path in fluid communication with the ejection outlet to supply the liquid to the ejection outlet and having the electrothermal transducer element on its bottom side; and a step of applying the thermal energy to the liquid to cause the liquid to undergo a change of state and thus to create a bubble. The liquid is ejected through the ejection outlet by the pressure of the bubble. The bubble is first in communication with ambience during reduction of the volume of the bubble after the bubble reaches a maximum volume.
