摘要： PROBLEM TO BE SOLVED: To enhance the convenience of replacing ink tanks while suppressing a manufacturing cost low by a simple designing and manufacturing process without using a plurality of kinds of ink tanks. SOLUTION: A pair of standard ink tanks 201 are set and coupled to both sides of an ink tank coupling member 90, which are mutually fixed by a loop- shaped uniaxially drawn thermal shrinkage film 101, thereby constituting a large capacity ink tank module 205. A black ink is stored in the ink tank module 205, which is mounted to a mounting region 1 of a holder 30. Standard ink tanks 201 in which inks of cyan, magenta and yellow colors are stored respectively are mounted to mounting regions 2-4 of the holder 30 respectively.

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 suppress fluctuation of frictional coefficient of incident to charges by compressing an ink absorber using a press member and inserting them simultaneously into a container having dimensions smaller than those of the absorber and withdrawing the press member from the container while holding it in the container thereby removing charges from the press member. SOLUTION: An absorber 1 is pressed to have dimensions smaller than the internal dimensions of an ink tank container 3 using two pairs of press member 4, 5 and, while keeping the compressed state, the absorber 1 is inserted into the ink tank container 3 along with the press members 4, 5. It is further compressed by a third press member 6 to have a dimension smaller than the internal depth dimension of the ink tank container 3 and, while keeping the pressed state, each press member 4, 5 is withdrawn and the third press member 6 is separated from the absorber 1. Although charges are generated through rubbing of the container 3 and the press members 4, 5 and they stand on the absorber or the press member, they cause no significant problem on the absorber and the container because the absorber is inserted only once.

摘要： PROBLEM TO BE SOLVED: To obtain an ink tank containing an ink absorber in a polyhedral containing case in which the ink containing efficiency is enhanced without lowering the service efficiency of ink. SOLUTION: An ink absorber 120 for holding ink is contained in a case 110 constituting an ink tank. A plurality of ribs 101 are formed on two opposite inner wall faces of the case 110 having the largest area, and spaces becoming ventilation passages 150 for feeding air uniformly into the case 110 are defined by the ribs 101. The ribs 101 formed on one inner wall face of the case 110 are arranged at positions not facing the ribs 101 formed on the other inner wall face. Consequently, the density of the ink absorber is made uniform in the case 110 and the number of the ribs 101 can be decreased.

摘要： PROBLEM TO BE SOLVED: To enhance service efficiency regardless of the type of ink or ink absorber by controlling the distribution state of ink. SOLUTION: After a container 2 is decompressed by means of a vacuum pump 15, an on/off valve 13 is opened and ink is injected from an ink supply means 14. When a specified quantity of ink is injected, the ink is absorbed by an ink absorber 1 and stays in a buffer space 7. When the on/off valve 13 is closed and an opening 5 communicating with the atmosphere is opened, air in the ink absorber 1 expanded through pressure reduction is contracted, the ink in the buffer space 7 is sucked into the ink absorber 1, and the ink in the vicinity of the outer surface of the ink absorber 1 moves inward. A part of the ink absorber 1 touching a shield member 8 is shielded by a shield member 8 and, since the ink does not permeates that part, that part is not wetted with ink. The ink absorber 1 includes a region 11 which absorbed the ink sufficiently, a region 16 holding the ink slightly, and a region 12 unwetted with ink. Interface 9 of the ink is substantially horizontal and ensures a good distribution state of the ink.

摘要： PROBLEM TO BE SOLVED: To supply ink surely and stably from an ink supply opening even when the flow rate of ink is high by ensuring a large opening area of the ink supply opening when it is provided at such a part as the tank width cannot be ensured sufficiently. SOLUTION: A second negative pressure generating member 1 is contained in a substantially rectangular parallelepiped ink containing section 2 and disposed between a first negative pressure generating member 3 and a plane forming an ink supply opening 4. The rectangular parallelepiped second negative pressure generating member 1 has a width equal to the width between the inner wall faces becoming the maximum area plane of the ink containing section 2. The rectangular parallelepiped second negative pressure generating member 1 is surrounded by a guide 5 comprising the two opposite inner wall faces becoming the maximum area plane of the ink containing section 2, and two opposite and parallel inner wall faces provided substantially perpendicularly to the ink supply opening plane while intersecting the two opposite inner wall faces.

摘要： PROBLEM TO BE SOLVED: To provide a liquid container which can be mounted/dismounted without causing any dripping of liquid and exhibiting a high liquid containing efficiency and excellent handling performance. SOLUTION: An ink tank unit 200 comprises an ink container 201 having an inner bag 220 containing ink being fed to a recording head, a joint port 230 for supplying ink to the recording head when the joint pipe thereof is inserted, and a member 255 for absorbing ink adhering to the joint port 230 into a space different from the inner bag 220. The ink reabsorbing member 255 has an ink absorbing region 255a adjacent to the joint port 230, and a region 255b for storing ink absorbed into the ink absorbing region 255a. Capillary force of the ink storage region 255b is higher than that of the ink absorbing region 255a.

摘要： PROBLEM TO BE SOLVED: To provide a fiber material capable of providing the ink supply property compatible with various inks and high speed printing as well as facilitating the ink ejection, and a liquid storing container having the same. SOLUTION: An ink tank 1 is provided with a PP fiber material (the sectioned part in the figure) 2 as a negative pressure generating member with respect to an ink-jet head for recording by ejecting a liquid over the substantially the entirety of the inside such that the liquid to be supplied to the ink-jet head is sustained by the PP fiber material 2 for storage. An atmosphere communication opening 3 is provided on the upper end of a tank housing. Moreover, an entangled PP fiber with the surface processed by a hydrophilic treatment is used as the PP fiber material 2.
