Abstract: PROBLEM TO BE SOLVED: To prevent liquid being fed into a liquid ejection head from thickening due to temperature drop in a method for sustaining liquid ejection performance of a liquid ejector for ejecting liquid supplied from a liquid container into the liquid ejection head from a liquid ejection nozzle.
SOLUTION: In the method for sustaining liquid ejection performance by preventing ink 16 supplied from an ink tank 1 from thickening in a print head 10 for ejecting the ink 16 from an ink ejection nozzle formed in the nozzle surface, the ink 16 is heated indirectly by means of heaters 4 and 4 provided on the outside of the ink tank 1 when the temperature of the ink 16 contained in the ink tank 1 lowers below a specified level. Since the ink 16 contained in the ink tank 1 for supplying ink into a print head 3 is prevented from thickening due to temperature drop, ink ejection performance can be sustained.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid jet head, a liquid jet device, and a degassing control device whereby a gas is discharged by a liquid naturally flowing out by virtue of hydraulic head difference between a liquid supply section and a head site to carry out degassing, thereby reducing the liquid jet head in size and in cost.
SOLUTION: This liquid jet device comprises a head section 2 for ejecting a liquid, the liquid supply section 3 for supplying the liquid to the head section 2, an opening/closing means 4 which is provided to a liquid supply path 22 coupling the head section 2 with the liquid supply section 3 in order to open or close the liquid supply path 22. An outlet 19 of the liquid from the liquid supply section 3 is positioned higher than the head section 2, and then the gas reserved in the head section 2 due to the hydraulic head difference between the both portions is discharged therefrom. As a result, it is possible to reduce the liquid jet head having the degassing function in size and in cost by obviating the need of a suction pump.

SOLUTION: The ink supply unit comprises an ink containing section 30, an ink chamber 40 coupled with the ink containing section 30, and a valve 50 arranged to move such that an opening/closing member 52 opens an opening area 51 as the pressure in the ink chamber 40 lowers due to decrease in the quantity of ink in the ink chamber 40. The ink containing section 30 comprises an air introduction pipe 32 extending from an outer air communication hole 32a into the ink containing section 30 and taking air corresponding, in volume, to the quantity of ink decreased in the ink containing section 30 from the hole 32a into the ink containing section 30 when the quantity of ink in the ink containing section 30 decreased, and a buffer section 32b capable of storing ink. The lower surface X1 between the lower end P1 and the side end P2 of the outer surface at the buffer section 32b is inclining upward from the central side of the buffer section 32b toward the outside.

Abstract: PROBLEM TO BE SOLVED: To prevent ink from leaking even at an inclination time or when a pressure or temperature change is brought about while making an ink storage amount large and the structure simple. SOLUTION: There are provided an ink storage part 20, an ink chamber 51 coupled to the ink storage part 20 so that ink in the ink storage part 20 can flow down, and a valve 52 for opening/closing between the ink storage part 20 and the ink chamber 51. The valve 52 is excited to shut between the ink storage part 20 and the ink chamber 51 and opens between the ink storage part 20 and the ink chamber 51 by a pressure decrease in the ink chamber 51 generated when the ink is supplied from the ink chamber 51. The ink storage part 20 is provided with an outdoor air communication hole 32a which communicates with the outdoor air, and an air introduction pipe 32 which extends to the inside of the ink storage part 20 and takes in the air from the outdoor air communication hole 32a when the quantity of ink of the ink storage part 20 reduces. A buffer part 32b for temporarily storing the ink is provided to a part of the air introduction pipe 32.
