    • A printer head member having ultrafine grooves of high density and high precision. In one or more embodiments of the invention, a flat plate made of ceramics, glass, silicon or the like is bonded and integrated to a partition wall made of a powder of ceramics, glass, silicon or the like, obtained by a molding process. The mold used for obtaining the partition includes ultrafine grooves that conform to the shape of a partition. In another embodiment of the invention, a member for passage having high density and high precision is obtained by a molding process. A flat plate made of ceramics, glass, silicon or the like is bonded and integrated to a partition wall made of a powder of ceramics, glass, silicon or the like, using a molding die having one or more fine grooves for forming one or more partition walls, wherein at least a passage is formed between the partition walls. One or more embodiments of the invention are directed to an ink jet printer head including one or more ink chambers, an ejection port communicating with the ink chambers, and a diaphragm for applying pressure to the ink chambers. The diaphragm is formed of conductive inorganic material, and a piezoelectric element bonded to the diaphragm. A driving electrode is formed on the piezoelectric element. The displacement of a piezoelectric element is favorably transmitted to the diaphragm.
    • 一种具有高密度和高精度的超细槽的打印机头部件。 在本发明的一个或多个实施例中,由陶瓷,玻璃,硅等制成的平板与通过模制工艺获得的由陶瓷,玻璃,硅等制成的分隔壁结合并整合。 用于获得隔板的模具包括符合隔板形状的超细槽。 在本发明的另一个实施例中,通过模制工艺获得具有高密度和高精度的用于通道的构件。 将由陶瓷,玻璃,硅等制成的平板用陶瓷,玻璃,硅等粉末形成的隔壁结合并整合,使用具有一个或多个细槽的成形模,形成一个或多个 分隔壁,其中至少在分隔壁之间形成通道。 本发明的一个或多个实施例涉及一种喷墨打印机头,其包括一个或多个墨室,与墨室连通的喷射口以及用于向墨室施加压力的隔膜。 隔膜由导电无机材料形成,并且压电元件结合到隔膜。 驱动电极形成在压电元件上。 压电元件的位移有利地传递到隔膜。
