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 a liquid head discharge head. The head has discharge ports, liquid flow paths, bubble generating areas, bubble generating means, liquid supply ports connecting the flow paths with a common liquid supply chamber, and a movable member in the flow paths supported with a minute gap to the supply ports. The area of the movable member surrounded at least by its free end and both sides continued therefrom is larger than the opening area of the supply ports. The method includes the step of setting a period for the movable member to substantially close the opening area during the period from the application of a driving voltage to the bubble generating means to the substantial termination of isotropical growth of the entire bubble by the bubble generating means. Growth of the bubble component in the direction opposite the discharge port can be suppressed, improving liquid refill.

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.
