    摘要： A pressurizing chamber 1 is formed as a recess by half etching of a silicon single-crystal substrate 2. A nozzle communicating hole 6 through which the pressurizing chamber 1 is connected to a nozzle opening 5 is formed as a through hole which is smaller in width than the pressurizing chamber 1. The pressurizing chamber 1 is connected to the nozzle opening 5 in the other face via the nozzle communicating hole 6 while reducing the volume of the pressurizing chamber 1 to a degree as small as possible. The silicon single-crystal substrate is used as a member constituting a spacer so that an ink drop of a reduced ink amount suitable for high density printing flies with high positioning accuracy.

    摘要： An ink jet recording head having high printing quality which is achieved independently of ambient temperature changes. An overhang portion (22) is formed on a surface of a frame (20) in such a manner that the overhang portion extends close to an island portion (9) of a resilient plate. A front end (17) of a fixed board (14) is fixed to the overhang portion (22) so that a gap (23) is interposed between a lateral side of the fixed board (14) and the frame (20). The piezoelectric vibration elements (8) are secured to the opposite end of the fixed board and abut against each of the island portions. The thickness (L0) of the overhang portion (22) affects that thermal expansion differential derived from a difference in the materials of the frame (20) and the piezoelectric vibration element. Since the thickness is minimized, the thermal expansion differential between the frame (20) and the piezoelectric vibration element (8) is correspondingly minimized.

    摘要翻译： 具有高的印刷质量的喷墨记录头，其独立于环境温度变化而实现。 在框架（20）的表面上形成伸出部分（22），使得伸出部分靠近弹性板的岛部（9）延伸。 固定板（14）的前端（17）固定在伸出部分（22）上，从而在固定板（14）的横向侧和框架（20）之间插入间隙（23）。 压电振动元件（8）固定在固定板的相对端上，并与每个岛部抵接。 突出部分（22）的厚度（L0）影响由框架（20）和压电振动元件的材料的差异导出的热膨胀差异。 由于厚度最小化，所以框架（20）和压电振动元件（8）之间的热膨胀差异相应地被最小化。

    摘要： There is provided a protection member configured to protect a liquid supply unit air-tightly. A cartridge 100 has an ink supply port 112 formed in a bottom surface 101 and an air hole 128 formed in a top surface 102. A protection member 200 is configured to be attachable to the cartridge 100. The protection member 200 includes a film member 201 configured to seal the air hole 128, and a cap section 220 configured to seal the ink supply port 112. The cap section 220 has a columnar support portion 232 having an upper end surface 235 which the film member 201 is joined with. The columnar support portion 232 is provided in an area opposed to a left side surface 105 of the cartridge 100.
