摘要： A printing system having an ink tank for storing ink, the ink tank having a housing having an ink feeding port formed through a first surface for feeding ink therethrough, and a second surface opposite the first. An ink absorbing member is accommodated in the housing, is a porous member having a three-dimensional net-shaped structure molded of a composition comprising a condensate of (i) a compound having an amino group and (ii) formaldehyde, and has a first surface facing the ink feeding port. An alleviating member having more resilience than the ink absorbing member is disposed between the ink absorbing member and an ink outflow portion formed through the ink feeding port and alleviates pressure applied by the ink outflow portion against the ink absorbing member. Both the alleviating member and the ink absorbing member are deformed by compression against the ink outflow portion. A compensating member having more resilience than the ink absorbing member is disposed between the ink absorbing member and the ink outflow portion and applies a functional force to the ink absorbing member corresponding to deterioration of properties of the ink absorbing member. Another ink absorbing member having more resilience than the ink absorbing member is disposed between the ink absorbing member and the ink outflow portion.

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。

摘要： An ink tank includes a housing and an ink absorbing member accommodated in the housing. The ink absorbing member is constructed using a water jet cutter. The ink absorbing member is a thermosetting foamed block having a porous three-dimensional divergent circuit network; the foamed block is molded of a condensate comprising a compound having an amino group and a formaldehyde. The foamed block is formed for placement in the housing by actuating the water jet cutter and worked by actuating the water jet cutter to provide slits or holes in the ink absorbing member different from pores of the foamed block.

摘要： An ink absorbing member is inserted in an ink tank housing which at least partly has a transparent portion. Used as this ink absorbing member is one having a reflection density after ink removal which is close to the reflection density of a melamine foam before ink injection. The amount of ink remaining in a cartridge of such a construction can be detected, for example, by a separate line sensor. The results of detection by the line sensor can be displayed by a remaining ink amount indicator provided on a control panel of the printing apparatus.

摘要： An inkjet recording head includes a recording-element substrate having arranged therein multiple sets of nozzles that discharge ink, energy-generating elements that generate energy used for discharging the ink, and supply ports that supply the ink to the nozzles; and a sealant disposed around the recording-element substrate. The supply ports include a first supply port disposed near a first edge of the recording-element substrate and a second supply port disposed near a second edge of the recording-element substrate, the second edge being opposite to the first edge as viewed in the arrangement direction of the multiple sets. As viewed in the arrangement direction, a distance between the second edge and the second supply port is shorter than a distance between the first edge and the first supply port, and a volume of the sealant near the second edge is smaller than a volume of the sealant near the first edge.

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.
