Abstract:
An ink absorbing body stores an ink injected into an ink tank for an ink-jet with capillary force between fiber. On a surface of said fiber before filling the ink, a surfactant is deposited within a range of 0.002 to 0.2wt% relative to a weight of the ink or in a range of 0.01 to 0.5wt% relative to a weight of the fiber.
Abstract:
An ink jet head includes a plurality of liquid flow paths (31) for ejecting the ink; and a plurality of heat generating resistors (2a,2b) for the respective liquid flow paths, the heat generating resistor being independently drivable; wherein adjacent ones of the heat generating resistors are spaced by not more than 8 microns.

Abstract:
An ink jet head including a base member (100); a first member (1300) having recesses and coupled with the base member to form ink passages using the recesses; a second member (400) integral with the first member (1300) and extending at an angle from an end fo the first member, the second member (400) having ink ejection outlets (41) communicating with the ink passages.
Abstract:
A method for coupling a liquid jet head unit is to couple a liquid jet head unit for recording by discharging liquid to a recording medium with a head installation member capable of installing the head unit through an elastic member. This method comprises the steps of preparing a liquid jet head unit structured integrally with two orifice arrays substantially paralleled and a first supply opening group for supplying liquid to the orifice arrays, and a head installation member provided with a second supply opening group corresponding to the first supply opening group for supplying liquid to the liquid jet head unit, and also, an elastic member having holes corresponding to each of the supply opening groups, providing first and second coupling units for one end side and the other end side of the two orifice arrays for coupling the liquid jet head unit and the head unit installation member, respectively and coupling only one face of the liquid jet head unit and the head unit installation member using the first and second coupling units. With the adoption of this method, it is possible to implement stabilized recording on a recording medium by means of stabilized ink supply, at the same time, preventing any erroneous installation in the coupling mode.
Abstract:
An ink jet cartridge includes a head portion; an ink container portion; an ink passage for supplying ink from the ink container portion to the head portion; ink absorbing material in the ink container; and a filter press-contacted to the ink container; a filter press-contacted to the ink absorbing material adjacent an end of the ink passage, the filter having an area larger than a cross-sectional area of the ink passage.
