摘要： PROBLEM TO BE SOLVED: To provide a liquid circulation device configured such that when the circulation of liquid in a nozzle is started, a change in pressure on the nozzle is restricted.SOLUTION: In the nozzle 11, while ink is held in a meniscus state, a difference pressure in circulation (-2,500 Pa(G)) is caused between the supply side pressure and recovery side pressure in the nozzle 11 during circulation to circulate ink. In this case, while a supply side valve 22 and a recovery side valve 26 are closed, the difference pressure between the supply side pressure and recovery side pressure is made lower than the difference pressure in the circulation (is made to be substantially zero). Then, the supply side valve 22 and recovery side valve 26 are opened. Then, the difference pressure is gradually changed to the difference pressure in the circulation.

摘要： PROBLEM TO BE SOLVED: To absorb the pressure fluctuation of a liquid of a supply channel to suppress the deterioration of transmission pressure to a downstream side of the supply channel in performing the discharge operation of the liquid from a liquid discharge part due to higher pressure than normal droplet discharge.SOLUTION: A damper 100 has elastic films 114A, 114B for forming the wall of the supply channel 30 of an ink L, an upper cover 104 and a lower cover 106 forming air chambers 118A, 118B partitioned by the elastic films 114A, 114B, and gas and liquid separation films 116A, 116B formed on the upper cover 104 and the lower cover 106 to resist pressure fluctuation caused by the fluctuation of the elastic films 114A, 114B. Here, when pressure acting on the ink L fluctuates, application pressure acting on the ink L is absorbed by fluctuating (deforming) the elastic films 114A, 114B. Then, since the fluctuation of the elastic films 114A, 114B is suppressed due to the ventilation resistance of the gas and liquid separation films 116A, 116B, the deterioration of pressure transmission to the downstream side of the supply channel 30 can be suppressed.
摘要翻译：要解决的问题：为了吸收供应通道的液体的压力波动，以抑制由于液体排出部分的液体的排出操作而导致的供给通道的下游侧的传输压力的劣化比正常的液滴放电压力高。解决方案：阻尼器100具有用于形成油墨L的供应通道30的壁的弹性膜114A，114B，形成由弹性膜114A分隔开的空气室118A，118B的上盖104和下盖106， 114B，以及形成在上盖104和下盖106上的气体和液体分离膜116A，116B，以抵抗由弹性膜114A，114B的波动引起的压力波动。这里，当作用在油墨L上的压力波动时，作用在油墨L上的施加压力被弹性膜114A，114B的波动（变形）吸收。而且，由于气体分离膜116A，116B的通风阻力使弹性膜114A，114B的波动受到抑制，所以能够抑制向供给路径30的下游侧的压力传递的劣化。版权所有（C）2012，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To suppress reattaching of ink air-discharged to an air discharge receiving part, to a head surface on which a nozzle part is formed. SOLUTION: Air-discharged ink flows down along the inclination of the air discharge receiving surface 48A of the air discharge receiving part 48. Accordingly, ink is less likely to deposit on the air discharge receiving surface 48A. In addition, since air-discharged ink flows down opposite a moisturizing liquid storage part 50, the ink is prevented from entering the moisturizing liquid storage part 50 and accumulating in this part 50. Thus, air-discharged ink is less likely to deposit on a moisturizing plate 42. Accordingly, even when the moisturizing plate 42 approaches the head surface 25 of each of inkjet recording heads 20Y to 20K, ink is less likely to be attached to the head surface 25.

摘要翻译：要解决的问题：为了抑制向排气接收部排出的油墨重新附着到形成有喷嘴部的头表面。解决方案：空气排出的油墨沿着排气容纳部分48的排气接收表面48A的倾斜度向下流动。因此，油墨不太可能沉积在排气接收表面48A上。此外，由于空气排出的墨水与保湿液体储存部分50相对流动，因此防止墨水进入保湿液体储存部分50并积聚在该部分50中。因此，排出空气的墨水不太可能沉积在因此，即使当保湿板42接近喷墨记录头20Y至20K的头表面25时，墨水也不太可能附着到头表面25.版权所有（C）2010， JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a droplet ejection head excellent in productivity, handling properties, and ejection characteristics, and to provide a droplet ejection apparatus which can form high-definition image information.
SOLUTION: When a nozzle 2a in a droplet ejection head 1 is formed by laser processing, a polymer material composing a nozzle plate 2 comprises a lubricant having an average particle size of 0.01 μm or more and 8% or less of the pore diameter of the nozzle 2a. According to the composition, the lubricant can exhibit its capability of imparting flowability to a polymer material during thermal molding by setting the average particle size of the lubricant to 0.01 μm or more. Further, by setting the average particle size of the lubricant to 8% or less of the pore diameter of the nozzle 2a, it is possible to prevent the lubricant from exposing from the nozzle to cause flash or processing failure when the nozzle is formed by laser processing. As a result, a droplet ejection head excellent in productivity, handling properties, and ejection characteristics can be obtained.
