摘要： A channel unit has an ink ejection surface that includes nozzles, another surface, a common ink chamber, pressure chambers, and individual ink channels each fluidly connecting the common ink chamber with one nozzle via a corresponding pressure chamber. An actuator unit is fixed to the another surface. The actuator unit is deformable to selectively change the volumes of the plurality of pressure chambers. A reservoir unit has a first surface fixed to the another surface, a second surface extending in parallel with the ink ejection surface, and an ink reservoir. The actuator unit is interposed between the channel unit and the reservoir unit. A base plate has a flat planar surface. A fixing portion fixes the base plate to the reservoir unit at at least one position, allowing the flat planar surface of the base plate to be in close contact with the second surface of the reservoir unit.

摘要： An image recording apparatus includes liquid ejection heads, wipers, and a movement means. The liquid ejection heads respectively have ejection faces, and are arranged in such a manner that the ejection faces form two rows extending in one direction and in addition two of the ejection faces included in different rows do not overlap each other along a direction perpendicular to the one direction. The liquid ejection heads are divided into one or more head groups each including two of the liquid ejection heads corresponding to the different rows. The movement means moves two of the wipers associated with two liquid ejection heads belonging to each head group, from inner end portions of the ejection faces in opposite directions along the perpendicular direction while keeping the two wipers in contact with the ejection faces.

摘要： When all metal plates for forming a passage unit of an ink jet head are bonded together by metal bonding, a top metal plate will warp, and an actuator unit cannot be fitted in a uniform manner to this warped top metal plate, and if the actuator units are not fitted in a uniform manner to the top metal plate, a uniform amount of ink cannot be discharged from nozzles of the ink jet head. To deal with this, metal diffusion bonding of the metal plates is performed without the top metal plate being included therein, and the top metal plate is then caused to adhere by means of adhesive. There is thus no warping of the top metal plate, and consequently the actuator units can be fitted in a uniform manner to the top metal plate.

摘要翻译： 当用于形成喷墨头的通道单元的所有金属板通过金属接合粘合在一起时，顶部金属板将翘曲，并且致动器单元不能以均匀的方式安装到该翘曲的顶部金属板上，并且如果致动器 单元不能以均匀的方式安装到顶部金属板上，因此不能从喷墨头的喷嘴排出均匀的墨水量。 为了处理这种情况，金属板的金属扩散接合是在不包含顶部金属板的情况下进行的，然后通过粘合剂使顶部金属板粘合。 因此，顶部金属板没有翘曲，因此致动器单元可以均匀地装配到顶部金属板。

摘要： An ink-jet head comprises a passage unit with an ink passage formed therein and a branching passage unit, and is constructed by laminating the passage unit and the branching passage unit with each other. The ink passage extends from a common ink chamber for supplying ink to a pressure chamber toward a nozzle. The branching passage unit includes an ink branching passage for branching ink from an ink introduction port to ink outlet ports. The outlet ports leads out ink into the passage unit. Inlet ports for introducing ink into the common ink chamber are formed on a surface of the passage unit. Ink outlet ports in the branching passage unit are disposed so as to face the inlet ports. Filters for removing foreign matters mixed in ink are formed in the ink branching passage within the branching passage unit.

摘要： A stencil stamp assembly having a comparatively small size, high ink holding capacity, excellent stamping durability and is capable of stamping images having a high print quality. The stencil stamp includes a handgrip and a stencil stamp assembly. The stencil stamp assembly includes an ink bearing member covered with a thermal stencil sheet. The thermal stencil sheet has a plurality of pores on holes arranged in a pattern. During a stamping action, ink from the ink bearing member is forced through the pores in the stencil sheet and onto a recording sheet to form a stamped image on the recording sheet. The ink bearing member has at least two layers having different densities. The less dense layer is in contact with the thermal stencil sheet. The least dense layer provides a large ink storage capacity. The more dense layer has a higher ink holding capacity, which reduces the potential for ink leakage. The more dense layer is also more firm, which reduces creasing and distortion of the stencil sheet both during stamping and during formation of the pore pattern in the stencil sheet.

摘要翻译： 具有比较小尺寸，高油墨保持能力，优异的冲压耐久性并且能够冲压具有高打印质量的图像的模版印模组件。 模板印模包括手柄和模板印模组件。 模版印模组件包括用热模板覆盖的油墨承载部件。 热模板具有以图案排列的孔上的多个孔。 在冲压动作期间，来自墨水支承构件的墨水被迫通过蜡纸中的孔和记录纸，以在记录纸上形成冲压图像。 油墨承载构件具有至少两层具有不同密度的层。 较不致密的层与热蜡纸接触。 最低密度的层提供了大的墨水存储容量。 更稠密的层具有较高的油墨保持能力，这降低了油墨泄漏的可能性。 更致密的层也更坚固，这在冲压期间和在模板中的孔图案的形成期间减少了蜡纸的折痕和变形。
