摘要： A method for manufacturing a liquid discharge head comprises the steps of providing a head main body having liquid flow paths, and an aperture surface having flow path openings communicated with the flow paths; providing a discharge port plate having extrusions each on the circumference of an inside opening communicated with each of the discharge ports, being on the inner face on the side opposite to the discharge port surface provided with discharge ports for discharging liquid, and a base having a substantially flat surface. For this method, the discharge port plate is arranged in a state of these surfaces formed integrally to be in contact; bonding the aperture surface and the inner face to fit the extrusions into the flow path openings by pressing the head main body and the base in the direction of the head main body and the base approaching each other with the discharge port plate between them; and separating the base from other members. With the method of manufacture thus structure, the liquid discharge head presents an excellent discharge efficiency by the provision of the extrusions that enter the flow paths from the orifice plate. It also becomes possible to manufacture a highly reliable liquid discharge head by a simpler manufacturing apparatus in a shorter period of time at lower costs.

摘要： A liquid discharging method for discharging liquid, which uses the pressure exerted at the time of creating each of bubbles in liquid in a bubble generating area, is arranged to provide two bubble generating areas for generating bubbles in such a manner as to enable these areas to face each other at least partly, hence discharging liquid by means for the pressure thus exerted in the bubble generating areas. In this way, it becomes possible to increase the amount of liquid discharged, as well as to enhance the durability of the movable members, while stabilizing the discharge of liquid from each of the discharge openings.

摘要： A length of a melamine foamed block to be accommodated in an ink tank housing as measured in the longitudinal direction is dimensioned to be larger than a length of the ink tank housing as measured in the longitudinal direction. Thus, while the foamed block is accommodated in the ink tank housing, it is compressed in the direction orienting toward an ink feeding port from which ink is fed to a printing head, i.e., in the ink feeding direction. Consequently, the ink retaining force induced by the capillary force is not intensified in the compressing direction of the melamine foamed block, resulting in an ink feeding capability of the printing head being improved. On the contrary, the ink retaining force effective at a right angle relative to the compressing direction of the melamine foamed block is intensified.

摘要翻译： 沿长度方向测量的容纳在墨罐壳体中的三聚氰胺泡沫块的长度的尺寸设定为大于沿纵向测量的墨罐壳体的长度。 因此，当发泡块被容纳在墨盒壳体中时，它被朝着朝向从墨水供给到打印头，即在供墨方向上的供墨口的方向上被压缩。 因此，毛细管力引起的墨水保持力在三聚氰胺泡沫块的压缩方向上没有增强，导致打印头的供墨能力得到改善。 相反，加强了相对于三聚氰胺发泡块的压缩方向成直角有效的油墨保持力。
