摘要： An ink jet head including a main body and a nozzle plate, wherein the main body changes the volume in a pressure chamber by deformation of a laminate piezoelectric device and thus feeds ink filled in the pressure chamber toward the front opening of the pressure chamber. The nozzle plate includes a nozzle hole communicating with the front opening of the pressure chamber and bonded to the front end of the main body with adhesive. The adhesive forms a nozzle seal layer of an arbitrary width in such a manner as to encompass the nozzle hole and the periphery of the front opening of the pressure chamber, an outer periphery hermetic layer of an arbitrary width round the outer periphery of a region in which the main body and the nozzle plate oppose each other, and a reinforcing layer scattered in an intermediate portion between the nozzle seal layer and the outer periphery seal layer.

摘要： An ink-jet head using a bimorph driver is disclosed. The head comprises a compartment (6) communicating with a nozzle (9) for storing ink, and a bimorph driver provided with a piezoelectric element (1) and a diaphragm (2) to apply pressure to the compartment (6). The bimorph driver has three fixed sides and one free side. Since one side of the piezoelectric element of the bimorph driver is open, tensile stress can be released while preventing pressure leakage. Therefore, even a narrow piezoelectric element can produce a displacement and pressure required to spray ink drops, resulting in a high-density multiple-nozzle head.
摘要翻译：公开了一种使用双压电晶片驱动器的喷墨头。头部包括与用于存储墨水的喷嘴（9）连通的隔室（6），以及设置有压电元件（1）和隔膜（2）以向隔室（6）施加压力的双压电晶片驱动器。双压电晶片驱动器有三个固定侧和一个自由端。由于双压电晶片驱动器的压电元件的一侧是开放的，所以可以在防止压力泄漏的同时释放拉伸应力。因此，即使是窄的压电元件也可以产生喷墨滴所需的位移和压力，从而形成高密度的多喷嘴头。

摘要： A printhead for an ink jet printer with an array (14) of ink ejection nozzles (22) formed from MEMS techniques. To protect the delicate nozzle structures, a nozzle guard (80) covers the exterior surface of the array (14). A corresponding array of apertures (84) is formed in the guard (80). To attach the guard (80) to the silicon substrate (16) carrying the nozzles (22), alignment formations (148) configured for engagement with complementary formations on a nozzle guard (86). For precise registration between the nozzles (22) and the respective apertures (86) in the guard (80), the alignment formations (148) may be formed using the same etching and deposition techniques used to form the nozzles (22). To protect the fragile nozzle structures (22) from inadvertent contact with the struts (86) during assembly, the nozzles (22) are reinforced by sacrificial material (152) which subsequently removed by an oxygen plasma etch (154).

摘要： In the particular embodiments described in the specification, a single pass ink jet printer includes a plurality of ink jet modules (54) arranged in adjacent rows extending across the width of the surface of an object which is moved with respect to the printer. The modules (54) are mounted on and joined to a manifold (84) which is mounted in a support frame (82). Ink is supplied to the manifold through an opening (98) in the frame and the manifold distributes the ink to corresponding openings (66) in the ink jet modules where it is directed to arrays of ink pressure chambers and to an outlet which communicates with a corresponding return passage (102) in the manifold leading back to the ink supply. As a result, ink can be circulated continuously through all of the ink jet modules, thereby maintaining pigment in suspension in a pigmented ink. An ink supply is removably connected to the printhead through quick-disconnect couplings and, to prevent contamination of the ink in the printhead, filters are provided in the ink supply and at the inlet to the printhead. A further filter (86), designed to trap only those particles which would block the orifices in the orifice plate, is positioned between the ink jet modules (54) and the orifice plate (90). In one embodiment twelve ink jet modules (54) are arranged to provide approximately 275 dot per inch (108 dot per cm.) resolution across a 5.6 inch (14.2 cm.) image width and in another embodiment forty-eight ink jet modules (54) are arranged to provide 600 dot per inch (236 dot per cm.) resolution across a 10.-1/4 inch (26 cm.) image width.
摘要翻译：在说明书中描述的特定实施例中，单通道喷墨打印机包括布置在相对于相对于打印机移动的物体的表面的宽度上的相邻行中的多个喷墨模块（54）。模块（54）安装在并连接到安装在支撑框架（82）中的歧管（84）上。墨水通过框架中的开口（98）供应到歧管，并且歧管将墨水分配到喷墨模块中的相应的开口（66），在那里它被引导到墨水压力室的阵列，并连接到与歧管中的相应的返回通道（102）导向墨水供应。结果，油墨可以连续地循环通过所有的喷墨模块，从而将颜料悬浮在着色油墨中。墨水供应通过快速断开的联接器可拆卸地连接到打印头，并且为了防止打印头中的墨水被污染，在墨水供应器和打印头的入口处提供过滤器。设计成仅捕获那些阻挡孔板中的孔的颗粒的另外的过滤器（86）位于喷墨模块（54）和孔板（90）之间。在一个实施例中，十二个喷墨模块（54）布置成在5.6英寸（14.2cm）的图像宽度上提供大约每英寸275点（108点/厘米）分辨率，在另一实施例中，四十八个喷墨模块（54 ）被布置成在10-1 / 4英寸（26厘米）的图像宽度上提供600点/英寸（236点/厘米））分辨率。
