摘要： The nozzle plate of an ink jet print head is made of glass to provide a desirable wetting property for a stable meniscus of the ink column and the front surface of the plate is coated with a non-wetting material such as metal or plastic to prevent ink deposits at the front surface around the orifice. Any ink deposits at such front surface would adversely affect the ejection of ink droplets.
摘要翻译：喷墨打印头的喷嘴板由玻璃制成，以为油墨柱的稳定的弯液面提供理想的润湿性能，并且该板的前表面涂覆有非润湿材料如金属或塑料以防止油墨在孔周围的前表面沉积。在这种前表面处的任何墨水沉积将不利地影响墨滴的喷射。

摘要： Means for supplying ink to a plurality of individually-spaced movable print heads is caused to be moved in a direction therewith but which ink supply means is positioned and directed in a manner perpendicular to the direction of movement of the print heads. An ink container is fixed at a distance from the print heads and a separate flexible ink supply tube, extending substantially in a vertical direction, connects the container with each individual print head. The ink supply tubes are movably swung or pivoted as the print heads are caused to be laterally moved and the swinging or pivoting movement of the supply tubes prevents interruption of the flow of ink to the print heads upon reversal of travel thereof at the ends of the printing lines.
摘要翻译：使得向多个单独间隔的可移动打印头供墨的装置沿着与其相反的方向移动，但是哪个墨供给装置以与打印头的移动方向垂直的方式定位和定向。墨水容器固定在与打印头一定距离处，并且基本上沿垂直方向延伸的单独的柔性墨水供应管将容器与每个单独的打印头连接起来。当打印头被横向移动时，供墨管可移动地摆动或枢转，并且供应管的摆动或枢转运动防止在反向在打印头的端部处的墨水逆向打印头印刷线。

摘要： An ink jet print head has a plurality of nozzles arranged in a vertical line at the printing end and connected by respective ink channels to pressure cavities in a circular arrangement at the ink supply end. The pressure cavities are supplied from an intermediate chamber contained in the print head and formed in a thin elongated shape and positioned generally in a plane parallel with the line of the nozzles. The construction of the print head compensates for acceleration and deceleration forces which are induced in the ink due to movement of the print head in the horizontal direction or perpendicular to the plane of the nozzles.
摘要翻译：喷墨打印头具有多个喷嘴，其在打印端处以垂直线布置，并且通过相应的墨水通道在墨水供应端处以圆形布置的压力腔连接。压力空腔从包含在打印头中的中间室供应并且形成为细长形状并且大致位于与喷嘴线平行的平面中。打印头的结构补偿由于打印头在水平方向上移动或垂直于喷嘴平面而在油墨中引起的加速和减速力。

摘要： An actuator including a solenoid and a "U"-shaped leaf spring. One end of the leaf spring is fixed to one end of the solenoid and the other end (a free end) of the leaf spring is located near the opposite end of the solenoid and is free to be attracted to the opposite end of the solenoid when it is energized. An actuating element is fixed to the free end of the leaf spring and is brought into operative engagement with a record medium when the actuator is actuated. A plurality of the actuators are arranged in a circle in a frame to produce a print head of the wire matrix variety. The actuators can also be used to punch holes in a record medium.

摘要： A mold having a desired print head shape includes a cover in which a plurality of rods or ductile fibers are attached, the cover being positioned with the rods extending into the mold and to the side opposite the cover. A hardenable synthetic material is introduced through a hole in the cover and after hardening of the material to form the print head, the rods are withdrawn from the mold to leave bores or apertures in the print head which serve as passageways for the droplets of ink.
摘要翻译：具有期望的打印头形状的模具包括其中附接有多个杆或延性纤维的盖，所述盖定位成具有延伸到模具中的杆和与盖相对的一侧。可硬化的合成材料通过盖中的孔引入，并且在材料硬化之后形成打印头，杆从模具中取出，以留下打印头中的孔或孔，用作油墨液滴的通道。
