Abstract: The present invention makes it possible to improve the alignment accuracy of the joint section of an ink cartridge with an ink supply route of an inkjet head. Based on this, the present invention provides an ink cartridge capable of preventing ink leakage with high reliability and constructed inexpensively in a reduced size and particularly suitable for a pit-in system. To attain this, distance (L1) is set to be shorter than distance (L2), where the distance (L1) is the one between a joint section (145) positioned in the proximity of a front surface (1A) of an ink cartridge (1) and an engage reference portion (135) serving as a reference position when the ink cartridge (1) is installed in the inkjet printing apparatus; and the distance (L2) is the one between the front surface (1A) of the ink cartridge (1) and the engage reference portion (135).

Abstract: Provided herein is an aqueous ink, which is excellent in both image density and fixing ability irrespective of the kind of a recording medium even when the volume of an ink droplet is small and has such excellent properties that white stripes are not caused even when high-speed recording is conducted. The aqueous ink comprises at least water, a water-soluble organic solvent, a water-insoluble coloring material, a surfactant and a poor medium for the water-insoluble coloring material and/or a salt. The dynamic surface tension of the aqueous ink at a lifetime of 50 milliseconds determined by a maximum bubble pressure method is higher than 47 mN/m, and the dynamic surface tension at a lifetime of 5,000 milliseconds determined by the maximum bubble pressure method is 38 mN/m or lower.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a liquid jet head which enables a channel configuration of the liquid jet head having a thin film movable member arranged to a liquid channel between a top plate and an element substrate whereby the thin film movable member can be positioned highly accurately to each liquid channel and prevented from being damaged or deformed at a cutting time, and a shape change by a difference of a coefficient of thermal expansion to the element substrate because of a temperature change can be limited to a minimum. SOLUTION: The liquid jet head has the thin film movable member arranged to the liquid channel between the top plate and the element substrate. A latent image of a supporting member 5 for the movable member 10 is formed onto the element substrate 1 by a photolithographic technique, onto which a thin film sheet 6 having a laser processability is attached. The movable member 10 and a flank at the cutting time are formed by laser processing, cut and divided to discrete chips. Thereafter, exposure and removal are carried out, and each of the movable member 10 and its supporting member 5 is arranged highly accurately to a corresponding heating element 2.

Abstract: PROBLEM TO BE SOLVED: To ensure highly accurate temporary positioning at the time of pasting a thin film material to an element board arranged with heating elements by abutting the thin film material against an abutting reference member at a temporary positioning part and then shifting the reference member to a temporary positioning reference position. SOLUTION: When abutting reference members 1a, 1b are previously shifted slightly from the end face of a base 2a, a thin film material P abutting against the abutting reference member 1a, 1b may touch the member 1a, 1b at two points. When the reference member 1a abuts against the base 2a at first, the thin film material P comes into line contact with the member 1a thus ending positioning in the X direction. Subsequently, a part of the material P projecting in the Y direction is pressed against the base 2a by means of the member 1b thus ending positioning in the Y direction. Finally, a microporous medium 3 is deaired and adsorbed thus completing temporary positioning of the thin film material P.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid discharge head and its manufacturing method which enable a channel configuration whereby a thin film movable member can be highly accurately positioned in the liquid discharge head having the thin film member arranged to a liquid channel between a top plate and an element substrate and prevented from being damaged at a cutting time, and thermal conduction from a heating element is not required to be taken into account. SOLUTION: The liquid discharge head has the thin film movable member arranged to the liquid channel between the top plate and the element substrate. A latent image of a supporting member 15 for the movable member 20 is formed by a photolithographic technique onto the top plate 11, on which a thin film sheet 16 having a laser processability is attached. The movable member 20 and a flank at the cutting time are formed by laser processing, cut and divided to discrete chips. Thereafter, exposure and removal are carried out. Since the movable member 20 and the supporting member 15 are formed to the top plate 11 in this manner, thermal conduction from the element substrate where the heating elements are formed becomes negligible, and the movable member 20 can be arranged highly accurately.

Abstract: PROBLEM TO BE SOLVED: To produce a negative pressure-generating member which is simple to manufacture, is superior in productivity and can realize stable supply of ink. SOLUTION: A sliver 43 of two kinds of thermoplastic synthetic fibers of different melting points is produced, which is passed through a pipe-shaped member 71 to align a fiber orientation. The sliver is preheated in a clean oven 44 to a temperature not lower than a lowest melting point and not higher than a highest melting point of the synthetic resins, and then heated again in a hot-air oven 74 to a temperature not lower than the lowest melting point and not higher than the highest melting point of the synthetic resins. The sliver is passed at a constant velocity through a nozzle 46 having a desired throttling diameter, and cut to a desired length.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a print head capable of detecting a position shift of a substrate when the substrate is placed on a jig provided as a reference. SOLUTION: A substrate 1 has an upper face as a first face where a plurality of energy generating elements are provided and a lower face as a second face which is parallel to the upper face. The substrates 1 are arranged on an upper face as a first face of a base plate 3 in a direction of arrow X. Each substrate 1 is grasped by a finger 5 which is movable in a direction of arrow Z and the base plate 3 is movable in directions of arrows X, Y and is rotatable around an axis P. The position and attitude of the substrate 1 is adjusted such that the substrate 1 and upper face of the base plate 3 to which the substrate is contacted are parallel with each other, then they are brought into contact with each other.
