摘要： An ink jet head is disclosed for use with a drop-on demand type printer, and includes an insulating base, a plurality of elongated barriers projecting upwardly from the base so as to form a plurality of slots between the barriers, a plurality of nozzle holes communicating with the slots, and electrodes formed on the side walls of the elongated barriers. Voltage can be applied to the various barriers through the electrodes in order to cause deflection of the barriers and a corresponding reduction in the cross-sectional area of selected slots, so as to force ink contained in the slots to be jetted through the nozzle holes. In order to provide a uniform ink jet intensity from the outermost slots relative to the inner slots, dummy slots can be formed outwardly of the outermost active slots by providing dummy barriers outwardly of the outermost active barriers. In addition, the nozzle holes are formed in a nozzle plate. The nozzle plate can either be mounted against the ends of the slots, or atop the base. When mounted atop the base, possible breakage of the ends of the barriers is less of a problem. Further, the plurality of barriers can either be mounted to the base by an adhesive, or can be formed integrally with the base. Also, the ink jet head can be formed with two bases, one atop the other, with the barriers of the bases being polarized in opposite directions.
摘要翻译：公开了一种与滴式打印机一起使用的喷墨头，并且包括绝缘基座，从基座向上突出的多个细长障碍物，以在屏障之间形成多个槽，多个喷嘴孔与狭槽连通，以及形成在细长屏障的侧壁上的电极。电压可以通过电极施加到各种屏障上，以便引起屏障的偏转和相应的所选狭缝的横截面积的减小，从而迫使包含在槽中的墨水通过喷嘴孔喷射。为了从最外侧槽相对于内槽提供均匀的喷墨强度，可以通过在最外面的活动屏障外面提供虚拟屏障，在最外面的活动槽的外侧形成虚拟槽。此外，喷嘴孔形成在喷嘴板中。喷嘴板可以安装在狭槽的端部，也可以安装在底座的顶部。当安装在基座顶部时，障碍物端部的可能的破裂就不是问题了。此外，多个屏障可以通过粘合剂安装到基座上，或者可以与基座一体地形成。此外，喷墨头可以形成有两个基座，一个在另一个之上，基座的屏障沿相反的方向极化。

摘要： A grinding machine comprising a tool mounting head which is movable vertically between a pair of guide columns on which guide surfaces are provided for guiding the head. A plurality of workpieces are mounted on corresponding holding jigs which are mounted by means enabling them to be tilted, and measurement means such as X-ray or optical means are provided to sense the orientation of a workpiece being machined, with signals from the measurement means controlling the tilting of the corresponding holding jig. Jigs are mounted on a rotary table rotatably mounted on a workpiece slide which can be traversed below a grinding tool.

摘要： A machine tool elevating and guiding apparatus comprising a tool mounting head which is movable vertically between a pair of guide columns. Guide surfaces on the guide columns are positioned closely adjacent to guided surfaces on the tool mounting head and a flow of pressurized fluid is passed at a fixed pressure between the guide and guided surfaces, such as to eliminate tilting of the tool mounting head. At least one guide surface serves as a reference surface, with a thin film of pressurized lubricating oil being formed between this and an adacent guided surface. The tool mounting head is mounted on an elevating feed screw, with means provided whereby the weight of the head is supported independently of that screw, so that a very high degree of precision in vertical positioning of the tool mounting head is attained.
