摘要： PROBLEM TO BE SOLVED: To form a fiber assembly having a low fiber density, uniformity and large thickness. SOLUTION: A heating furnace 10 has a hot air producing unit 11 and a mold unit 20 detachably arranged above the hot air producing unit 11. The mold unit 20 has a top force 22 and a bottom force 21 and a fiber laminate 50 is laid between them. The hot air producing unit 11 blows up hot air for heat-treating the fiber laminate 50 from below. In heat-treating the fiber laminate 50, the fiber laminate 50 is floated from the bottom force 21 and retained in such a degree as not to be pressed down by the top force 22. After the heat treatment, the top force 22 is dropped and the fiber laminate 50 being heated is compressed to a fixed thickness.

摘要： PROBLEM TO BE SOLVED: To obtain a fibrous layered product not having the needless compressive set in a downward direction along the gravitational direction, having a uniform density, excellent in wettability to ink and useful e.g. for a liquid-holding container by controlling the influence of gravitation acting on a layered product made up from a fibrous material in a thermal process. SOLUTION: This fibrous layered product is obtained by controlling in a thermal process the influence of gravitation acting on a layered product made up from a fibrous material such as fibers made of a thermoplastic olefin-based resin and mutually put side by side in nearly the same direction. The process for controlling the influence of gravitation is performed through operation rotating the layered product made up from a fibrous material in which the central axis of the rotational operation intersects the direction of the fiber and also falls at right angles with the gravitational direction. A liquid-holding container preferably is constituted in such a way as to hold the fibrous layered product and to store a liquid used for recording, and a liquid jetting head cartridge equipped with both the above container and a liquid jetting head capable of jetting the liquid stored in the container preferably is manufactured.

摘要： PROBLEM TO BE SOLVED: To obtain a capped liquid holding container in which a cap can be bonded with high watertightness and airtightness to the liquid holding container when a supply port made in the liquid holding container is enclosed while enhancing the operability at the time of unsealing. SOLUTION: A liquid 3 is held in a liquid holding container 1, a port 22 for supplying the liquid 3 to a recording element in an ink jet recorder is made in the container 1 and the supply port 22 is enclosed by a cap 2. A plurality of welding protrusions 6 are formed on the fringe at a tubular part covering the supply port 22 and welded to the container 1 by ultrasonic welding. Since the tubular part of the cap 2 is rigid, the cap 2 scarcely causes creep deformation and a capped liquid holder exhibiting high watertightness and airtightness is realized. Furthermore, operability is enhanced at the time of unsealing the container 1 because the cap 2 is removed therefrom by turning the cap 2 and shearing the welded part 6.

摘要： PROBLEM TO BE SOLVED: To eliminate a difference in an ink supplying characteristic for supplying ink from a tank between ejection sections for identical colors or colors having similar characteristics. SOLUTION: An ink supplying unit after being assembled is so constituted that inks supplied from supplying holes 41Y, 41M, 41C, 41B corresponding to joint sections to be connected to supplying holes of the ink tanks for yellow, magenta, cyan and black are supplied to six ejection sections 4C, 4M, 4Y, 4M, 4C, 5B on a recording head section through an ink supply passage (the portion drawn by dotted line in the figure) formed of the ink supplying section 41 and an ink supply passage forming assembly 42. The ink supply passage from the supply hole 41C corresponding to the joint section of the tank for cyan to the identical two cyan ejection sections 4C is divided into two passages in the way as in the magenta case and the lengths of the passages after divided are equal to each other.

摘要： PROBLEM TO BE SOLVED: To restrain scattering of an ink by sucking and taking in a liquid adhered on the inner surface of a cap of a liquid storage container at the time of opening the same. SOLUTION: At the time of opening a cap 14 from a liquid storage container 10, a part of an ink adheres on the liquid storage container 10 side and the surface of a projection 19 inside the cap 14 due to the surface tension. Thereafter, a spring force of a buffer room 16 member is opened so that the volume of the buffer room 16 is increased. As a result, an ink adhered on the projection 19 surface is sucked from a suction opening 17 provided in the surface center of the projection 19 via a communication path extending from the buffer room 16. The capillary force of the suction opening 17 is reinforced by the suction pressure of the buffer room 16, and the capillary force of a part of the buffer part side is weakened by the suction pressure. Thereby, a meniscus is formed before the buffer room at the time of finishing the ink suction in the vicinity of the suction opening 17 so as to stop the suction operation. In this case, the suction force of the buffer part is maintained.

摘要： PROBLEM TO BE SOLVED: To prevent ink leakage due to air passage between the holding member and a wall surface, or displacement of the holding member by the impact of dropping, or the like, by inserting an ink holding member comprising fibers laminated with the mingling fibers bonded with each other, after being compressed in the direction orthogonal to the maximum area surface of an ink tank case and the fiber direction. SOLUTION: A holding member 3 having a substantially rectangular parallelopiped shape is provided by fusing and bonding mingling laminated fibers with each other by heating. An ink tank case 5 comprises a first storage room 1 for storing a compressed ink holding member 4, and a second storage room for directly storing an ink, wherein a lid 11 is mounted after inserting the holding member 4 applied with compression from the lower end of the first storage room 1 of the half-raw ink tank 5 in the Z direction. The maximum area wall surfaces 6 among three pairs of wall surfaces in the first storage room 1 are substantially perpendicular to the fiber lamination direction Y. Accordingly, since a remarkable elastic deformation is enabled as well as a sufficient repulsion force is generated, the holding member can be closely contacted homogeneously without generating air passage with respect to the wall surfaces 6.
