    • A liquid jet recording head includes liquid discharge ports, pressure chambers, and a substrate which has the discharge energy generating element, a liquid chamber for storing a liquid supplied to the pressure chamber, a pair of paths which are separated from the liquid chamber, and a liquid supply port communicating with the liquid chamber. A liquid inlet port communicating with one path of the pair of paths and a liquid outlet port communicating with the other path of the pair of paths are opened on one surface of the substrate. A liquid flow path for discharging the liquid from the liquid chamber to the pressure chamber via the liquid supply port, and a liquid flow path for circulating the liquid from the one path to each pressure chamber via the liquid inlet port, and further from each pressure chamber to the other path via the liquid outlet port are provided.
    • 液体喷射记录头包括液体排出口,压力室和具有排出能量产生元件的基板,用于储存供应到压力室的液体的液体室,与液体室分离的一对路径,以及 与液体室连通的液体供给口。 与一对路径的一个路径连通的液体入口和与该对路径的另一路径连通的液体出口在基板的一个表面上打开。 一种用于经由液体供应口将液体从液体室排出到压力室的液体流路,以及用于使液体从一个路径经由液体入口循环到每个压力室的液体流路,并且进一步从每个压力 提供了经由液体出口连接到另一路径的腔室。

    • Second etching is performed to the bottom through dry etching of a substrate to suppress image degradation even if an opening position of an ejection opening at a substrate end deviates. Provided is an inkjet printing head substrate including: a first surface, a second surface, and a plurality of ink supply openings, wherein the plurality of the heat resistive elements and the plurality of the ink supply openings are arranged in such a manner that each of distances between a heat resistive element closer to an inclined surface of the recessed portion in the inkjet printing head substrate among the plurality of the heat resistive elements and two ink supply openings adjacent to the heat resistive element is longer than each of distances between a heat resistive element closer to the center of the inkjet printing head substrate and two ink supply openings adjacent to the heat resistive element.
    • 即使基板端部的喷射口的打开位置偏离,也可以通过对基板进行干式蚀刻来对底部进行第二蚀刻,以抑制图像劣化。 提供了一种喷墨打印头基板,包括:第一表面,第二表面和多个供墨开口,其中多个加热电阻元件和多个供墨开口以这样的方式布置: 在多个耐热元件中的靠近喷墨打印头基板的凹部的倾斜面的热阻元件与与该耐热元件相邻的两个供墨开口之间的距离比耐热性 靠近喷墨打印头基板的中心的元件和与耐热元件相邻的两个供墨开口。
