Abstract: Die vorliegende Erfindung ermöglicht, dass ein geeigneter Tintenfüllzustand eines Tintenbehälters durch Einstellen von Tinteneinfüllbedingungen erreicht werden kann, die Verhindern von Tintenleckage bei Entsiegeln eines Tintenzufuhrdurchlasses berücksichtigen. Ein Tintenbehälter (10) beinhaltet eine im Tintenbehälter (10) gebildete erste Speicherkammer (30) zum Speichern eines Tintenabsorbers (32), sowie eine auch im Tintenbehälter (10) gebildete zweite Speicherkammer (36) zum im Wesentlichen Bilden eines geschlossenen Raums bis auf einen mit der ersten Speicherkammer (30) kommunizierenden Verbindungsabschnitt (52). Nachdem der Druck im Tintenbehälter (10) durch einen Atmosphärenverbindungsdurchlass (12) auf einen Zieldruck reduziert worden ist, wird der Tintenbehälter (10) durch einen Tintenzufuhrdurchlass (14A) mit einer mit dem Zieldruck assoziierten Zielfüllmenge an Tinte im Inneren befüllt.

Abstract: The present invention enables a suitable ink filling state of an ink tank to be achieved by setting ink filling conditions taking prevention of ink leakage during unsealing of an ink supply port into account. An ink tank includes a first storage chamber formed in the ink tank to store an ink absorber, and a second storage chamber also formed in the ink tank to substantially form a closed space except for a communication section communicating with the first storage chamber. After the pressure in the ink tank is reduced to a target pressure through an atmospheric communicating port, the ink tank is internally filled, through an ink supply port, with a target filling amount of ink associated with the target pressure.

Abstract: The ink filling apparatus enables a suitable ink filling state of an ink tank to be achieved by setting ink filling conditions taking prevention of ink leakage during unsealing of an ink supply port into account. An ink tank 10 includes a first storage chamber (30, Fig.1) formed in the ink tank 10 to store an ink absorber (32, Fig.1) , and a second storage chamber (36, Fig.1) also formed in the ink tank 10 to substantially form a closed space except for a communication section (52, Fig.1) communicating with the first storage chamber (30, Fig.1). After the pressure in the ink tank 10 is reduced to a target pressure through an atmospheric communicating port (12,), the ink tank 10 is internally filled, through an ink supply port (14A, Fig.1), with a target filling amount of ink associated with the target pressure.

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.
