摘要： An air-assisted drop-on-demand ink jet head 10 has a single compartment ink chamber 14 and is designed for operation over a wide range of ink drop repetition rates, including extremely high repetition rates, such as twenty kilohertz. The components included in the ink jet head have natural resonance frequencies which are greater than the desired maximum drop generation frequency of the ink jet head. In addition, the natural frequency of each of the components of the ink jet head are sufficiently different from one another to prevent intercoupling. Ink is supplied to the ink chamber 14 via a supply inlet passageway 38 which has a cross-sectional area which is sized large enough to allow the supply of ink to the ink chamber. Yet, this area is small enough so that the natural frequencies of ink in the ink inlet do not significantly alter drop generating pressure pulses in the ink chamber 14.

摘要： An ink jet head 10 has an ink chamber 14 which receives ink from an ink inlet passageway 38. Pressure pulses applied to the ink chamber cause the ejection of ink drops from an ink drop forming orifice 23 and toward printing medium. A purging outlet 41 communicates with the ink chamber through a purging passageway 40. During purging, ink flows in a vortical path through the ink chamber 14 from the ink inlet passageway 38 to the purging outlet passageway 40. This sweeps air bubbles and contaminants from the ink chamber walls and removes them from the ink chamber. Ink pressure within the ink chamber 14 may be elevated to increase the flow of ink during purging. Also, a negative pressure may be applied to the purging outlet during purging. Variable frequency pressure pulses may also be applied to the ink chamber to assist the purging process.
摘要翻译：喷墨头10具有从墨入口通道38接收墨水的墨室14.施加到墨室的压力脉冲导致墨滴从墨滴形成孔23喷射到打印介质。清洗出口41通过清洗通道40与油墨室连通。在清洗过程中，油墨以涡旋路径从油墨入口通道38经过油墨室14流入清洗出口通道40.这样将气泡和污染物从墨水室壁并将其从墨水室中取出。油墨室14内的油墨压力可以升高以增加清洗期间油墨的流动。此外，在净化期间可以将负压施加到清洗出口。也可以将变频压力脉冲施加到墨室以帮助清洗过程。

摘要： Ink jet printing on a liquid medium can be performed using liquid inks having a thermo inversion gelling property. The liquid ink can include a hyperthermogelling component having a gelling temperature. When the liquid ink is jetted on the liquid medium, the liquid ink can gel to form gel dots. The gel dots can resist against liquid dispersion, allowing the formation of a high resolution image on the liquid medium.

摘要： A ferroelectric relaxor ceramic actuator material, such as lead magnesium niobate ("PMN"), has high electromechanical conversion efficiency, exhibits wide operating and manufacturing temperature ranges, does not require permanent polarization, and provides useful mechanical activity with reduced electrical drive voltages. A PMN actuator (66) may be bonded to an actuator diaphragm (64) with a high temperature soldering or brazing process. PMN material also has a diffuse Curie point range in which the dielectric constant (40), "d" coefficient (32), and dielectric loss (42) characteristics all rise to a peak and then fall as the temperature increases. A phase-change ink-jet print head (50) employs a PMN actuator that is compounded with lead titanate ("PT") to increase the temperature (T.sub.M) at which the peak dielectric constant occurs. The print head is operated at a temperature beyond the peak where the PMN:PT actuator "d" coefficient decreases as the temperature increases such that an increase in ink-jet drop ejection velocity caused by reduced ink viscosity is compensated for by a corresponding reduction in mechanical activity. The PMN:PT actuator thereby relaxes the temperature regulation and heat spreading requirements of the phase-change ink-jet print head.
摘要翻译：铁电弛豫陶瓷致动器材料，例如铌酸铅镁（“PMN”）具有高机电转换效率，表现出广泛的工作和制造温度范围，不需要永久极化，并且在降低的电驱动电压下提供有用的机械活动。 PMN致动器（66）可以通过高温焊接或钎焊工艺结合到致动器隔膜（64）。 PMN材料也具有扩散居里点范围，其中介电常数（40），“d”系数（32）和介电损耗（42）特性都全部升高到峰值，然后随温度升高而下降。相变喷墨打印头（50）采用与钛酸铅（“PT”）复合的PMN致动器，以增加出现峰值介电常数的温度（TM）。打印头的工作温度超过PMN：PT执行器“d”系数随着温度升高而降低的峰值温度，从而降低油墨粘度引起的喷墨滴落速度的增加可以通过相应的减小来补偿机械活动。因此，PMN：PT致动器松弛了相变喷墨打印头的温度调节和散热要求。

摘要： An aqueous phase change ink contains a selected concentration of hyperthermogelling component that causes the ink to gel when its temperature is increased to its thermo-inversion point or when the concentration of the hyperthermogelling component is increased by evaporation, or substrate absorption, of water from the ink. The ink may be jetted directly onto a heated and/or absorptive substrate or jetted onto a cooler and/or hydrophobic surface before being transferred to the substrate. The thermo-inversion point is preferably about ambient temperature, and the preferred hyperthermogelling component is a nonionic surfactant, such as an ethylene oxide propylene oxide block copolymer surfactant.
