摘要： An ink-jet recording apparatus includes an ink tank in a layered form and having a plurality of ink storage chambers (41-44) storing color inks; a driving circuit (37); a heat transfer plate (50); and a recording head having a plurality of nozzle rows arranged in one direction. The heat transfer plate (50) is in contact with the driving circuit (37) and faces, at a spacing distance, an ink storage chamber (44), among the ink storage chambers (41-44), storing a yellow ink included in the color inks, and formed on the lowest layer (44) of the ink tank. The yellow ink is supplied to a center nozzle row among the nozzle rows. This construction reduces an influence on printing quality due to variation in extent by which the color inks are influenced by the heat from the driving circuit, thereby providing an ink-jet recording apparatus which can realize high-quality printing and made to be compact.

摘要： A process for creating and an apparatus employing shaped orifices in a semiconductor substrate (20). A layer of slow cross-linking material (34) is applied on the semiconductor substrate (20). An orifice image (42) and a fluid-well image (43) is transferred to the layer of slow cross-linking material (34). That portion of the layer of slow cross-linking material (34) where the orifice image (42) is located is then developed along with that portion of the layer of slow cross-linking material (34) where the fluid well image (43) is located to define an orifice opening in the semiconductor substrate (20).

摘要： In the ink jet head unit of the present invention, an ink jet head for emitting ink in a form of droplets from nozzles formed in a nozzle plate (3) and a driving circuit (22) for driving the ink jet head (1) are mounted on the same surface side of the base board (21). A groove section (24) is formed in the surface, extending from the nozzle face of the ink jet head to the driving circuit. In the ink jet head, a temperature measuring section (25) is positioned in the groove section. Furthermore, there is provided a sealing member (26) in the groove section, to prevent the flow of ink emitted from the nozzles, into the driving circuit. The sealing member is partly formed of an elastic body (28). Therefore, it is possible to prevent the temperature change from impairing the ink jet head, consequently realizing ink projection stability.
摘要翻译：在本发明的喷墨头单元中，用于从形成在喷嘴板（3）中的喷嘴和用于驱动喷墨头（1）的驱动电路（22）以液滴形式喷射墨的喷墨头是：安装在基板（21）的相同的表面侧上。在表面上形成有从喷墨头的喷嘴面延伸到驱动电路的槽部（24）。在喷墨头中，温度测量部分（25）位于凹槽部分中。此外，在槽部中设置有密封构件（26），以防止从喷嘴喷射的墨流入驱动电路。密封件部分地由弹性体（28）形成。因此，可以防止温度变化损害喷墨头，从而实现墨水投影的稳定性。
