摘要： An ink dot printer comprising an opposite electrode, a carriage capable of reciprocating along the opposite electrode, a printing head mounted on the carriage, recording electrodes arranged within the printing head so that the tips thereof can be exposed through openings formed in a wall of the printing head opposite the opposite electrode, and a cap supported moveably on either the carriage or the printing head so as to close or open the openings of the printing head. When the ink dot printer is not in printing operation, the cap is closed to cover up the tips of the recording electrodes to prevent the drying of the tips of the recording electrode due to the evaporation of the ink so that the recording electrodes are always in good condition for stable printing operation.

摘要： A method and apparatus for fluid jet printing features a triode structured charge injection system. The ink jet system is not dependent upon the conductivity of the ink fluid to form and target the ink fluid. Two electrodes are in contact with the ink liquid and they are submerged in the fluid. One electrode is an emitter and serves to field emit charge into the liquid in response to a voltage between it and the other electrode. Depending upon the electrical mobility of the ink fluid, the injected charge will be trapped in the liquid. The liquid is then forced from an orifice and can be made to undergo break-up into droplets similar to inductively charged inks. The paper or target upon which the droplets impinge functions as a third electrode, returning the charge and completing the circuit. The ink may also be propelled as a charged column, which column can be directed by an extraneous electrical field for targeting upon the printing paper.
摘要翻译： 用于流体喷射印刷的方法和装置具有三极管结构的电荷注入系统。 喷墨系统不依赖于油墨流体的导电性以形成和对准油墨流体。 两个电极与墨液接触并将它们浸没在流体中。 一个电极是发射极，用于响应于其与另一个电极之间的电压而将电荷发射到液体中。 取决于墨水流体的电迁移率，注入的电荷将被捕获在液体中。 然后将液体从孔口迫使，并且可以使其分解成类似于感应充电的油墨的液滴。 液滴撞击的纸或目标作为第三电极起作用，返回电荷并完成电路。 油墨也可以作为带电柱被推进，该柱可以由外部电场引导以用于打印在打印纸上。

摘要： Ink is supplied into a discharge passageway (46) which tapers inwardly from the inlet (47) to the outlet (48) thereof with insufficient pressure to cause the ink to be ejected from the passageway (46). Inlet and outlet electrodes (49), (51) are provided at the inlet (47) and outlet (48) of the passageway (46) respectively. Another electrode (52) is provided external of the passageway (46). An electric potential is applied between the inlet and outlet electrodes (49), (51) to polarize the ink in the passageway (46). An opposite electric potential is applied to the external electrode (52) to cause the ink to be electrically attracted and discharged from the passageway (46) onto a sheet of paper (53) for printing. The external electrode (52) may be disposed either in front of or behind the sheet (53).
摘要翻译： 墨水被供应到排出通道（46）中，该排出通道（46）从入口（47）到其出口（48）向内渐缩，压力不足以使墨水从通道（46）中排出。 入口和出口电极（49），（51）分别设置在通道（46）的入口（47）和出口（48）处。 另一个电极（52）设置在通道（46）的外部。 在入口和出口电极（49），（51）之间施加电位以使通道（46）中的墨水偏振。 对外部电极（52）施加相反的电位，使墨水被电吸引并从通道（46）排出到用于印刷的纸张（53）上。 外部电极（52）可以设置在片材（53）的前面或后面。

摘要： The electrohydrodynamic print head includes a nozzle layer with a plurality of nozzles. A feed layer is arranged above nozzle layer. It contains feed ducts for feeding ink to the nozzles as well as electrically conducting feed lines for feeding voltages to electrodes at nozzles. The feed layer includes one or more dielectric sublayers, which is/are structured to form the feed ducts and feed lines. Some of the sublayers contain vertical via sections and others contain horizontal interconnect sections. The feed layer is structured for customizing the print head easily.

摘要： An arrayed electrohydrodynamic printhead without the extraction electrodes is provided. A printhead is formed by an ink cartridge, a flow channel plate, a nozzle plate, a control electrode layer. The ink cartridge includes an ink inlet, an ink outlet, an installation hole, a flow channel layer inlet, flow channel layer outlet. The flow channel plate has the functions of guiding the ink to flow into the nozzle plate and increasing the potential difference between the nozzles, and includes a flow channel inlet, a flow channel outlet, a drainage channel, and a microfluidic channel. A body of the nozzle plate includes nozzles and nozzle electrodes. The microfluidic channel forms a voltage division unit between each nozzle, so that the voltage on the triggered nozzle is dispersed in the flow channel without affecting other nozzles, and independent and controllable injection of each nozzle is thereby achieved.

摘要： A device comprising a supply, a first portion, a second portion, and a third portion. The supply is to supply a metallized, non-absorptive media along a travel path, which is electrically connectable to a ground element, the metallized media to carry a first polymer structure. The first portion along the travel path is to receive droplets of ink particles within a dielectric, non-aqueous carrier fluid on the first polymer structure on the media to form an image. The second portion is to apply an adhesion-promoting surface treatment, onto the ink particles and the first polymer structure, comprising UV ozone, plasma, or chemical additive. The third portion is to apply, via heat and pressure, a second polymer structure onto the ink particles and the first polymer structure to produce a media assembly.
