摘要： An inkjet head may comprise an ejection port which ejects ink and an ink flow path which supplies the ink to the ejection port. The inkjet head may also comprise an ejection actuator which supplies ejection energy to the ink in the ink flow path. The ejection energy may cause the ink to be ejected from the ejection port. The inkjet head may also comprise a wall portion. The wall portion may be located at a position farther from the ejection port along the ink flow path with respect to a position at which the ejection energy is supplied. The wall portion may define an inner wall surface of the ink flow path. The wall portion may deform to decrease a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as a temperature of the ink in the ink flow path increases. The wall portion may deform to increase a cross section of the ink flow path in a direction orthogonal to an ink-flow direction as the temperature of the ink in the ink flow path decreases.

摘要翻译： 喷墨头可以包括喷射墨水的喷射口和将墨水供给到喷射口的墨水流路。 喷墨头还可以包括向墨水流动路径中的墨提供喷射能量的喷射致动器。 喷射能量可能导致墨从喷射口喷出。 喷墨头还可以包括壁部分。 相对于供给喷射能量的位置，壁部分可以位于比喷墨口更远离油墨流动路径的位置。 壁部分可以限定油墨流动路径的内壁表面。 当油墨流路中的油墨的温度升高时，壁部分可以变形，从而沿与油墨流动方向正交的方向减小油墨流动通道的横截面。 当墨水流路中的墨水温度降低时，壁部分可以变形以增加与墨水流动方向正交的方向上的墨水流动通道的横截面。

摘要： The object of the invention is to provide a method for cleaning circulation water, which reduces the cost of operation and maintenance as much as possible, without a cumbersome cleaning operation such as by detaching electrode plates from an electrolysis cleaning tank and removing scale from inside the tank, and to provide a device used in this method. Accordingly, the present invention provides a method for cleaning circulation water, comprising the steps of flowing circulation water to be cleaned between electrode plates placed in a face-to-face manner between one another; and applying DC voltage between the electrode plates, allowing one or more metal ions contained in the circulation water to be precipitated onto the negative electrode plates by electrolysis, to clean the circulation water, wherein the electrode plates used are made of titanium plates, and wherein a desired amount of current flows, while an anodized oxide coating formed on the surface of the positive electrode plates is compulsively subject to dielectric breakdown by increasing the voltage applied to the anodized oxide coating. FIG. 1 is a representative drawing.
