摘要： A printhead used to eject fluid onto a recording medium has an integrated heat-sink which is used to cool the energy dissipation elements used to propel the fluid from the printhead. The printhead is comprised of a semiconductor substrate that has been processed with thin-film layers. On top of the thin-film layers is an orifice layer that has a pattern of orifices. Fluid feed channels, on the side of the printhead opposite the orifice, supply fluid to the pattern of orifices. Within the thin-film layers are energy dissipating elements which are used to transfer energy to the fluid thereby ejecting fluid from the orifice. The fluid is transferred to the orifice opening through fluid feed slots formed in the thin-film layer adjacent to the energy dissipation elements which is exposed in the fluid feed channel. An integrated heat-sink is attached to the energy dissipation elements to remove heat to the semiconductor substrate and the fluid supply in the fluid feed channel.

摘要： An orificeless thin film printhead for an ink jet pen which comprises a substrate having a plurality of vortex activators thereon, and ink dispensing means located adjacent to the substrate for providing a thin layer of ink of a controlled thickness over the surfaces of the vortex activators. A protective cover is disposed on the surface of the substrate and has one or more slots or other openings therein operative to expose the vortex activators during ink jet printhead operation. When each vortex activator is energized, the energy transferred from the surface of the activator into the liquid film creates a microjet and a shear force therein, followed by the formation of a vortex ring in the ink film. The vortex ring is in turn self-propelled at a relatively low velocity through the ink film to the free liquid surface thereby, producing stress at this surface to allow the high velocity ink at the core of the vortex ring to be efficiently transferred to an adjacent print medium with a high degree of directionality, thereby enhancing resolution and print quality on the printed media. In accordance with the present invention, vortex activators include, but without limitation, heater resistors, piston drivers, and piezoelectric cavities.

摘要： An improved ink flow path between an ink reservoir and ink ejection chambers in an inkjet printhead is disclosed along with a preferred printhead architecture. In the preferred embodiment, a barrier layer containing ink channels and firing chambers is located between a rectangular substrate and a nozzle member containing an array of orifices. The substrate contains two spaced apart arrays of ink ejection elements, and each orifice in the nozzle member is associated with a firing chamber and ink ejection element. The ink channels in the barrier layer have ink entrances generally running along two opposite edges of the substrate so that ink flowing around the edges of the substrate gain access to the ink channels and to the firing chambers. High speed printing capability with a firing frequency up to 12 KHz is accomplished by offsetting neighboring ink ejection elements from each other in each primitive grouping in the linear array, combining short shelf length with damped ink inlet channels, and then firing only one ink ejection element at a time in each primitive grouping thereby minimizing undesirable interference such as fluidic crosstalk between closely adjacent ink firing chambers. High resolution printing capability for at least 600 dots-per-inch by the printhead as a whole is accomplished by densely positioning the ink ejection elements in each linear array of ink ejection elements.

A first circuit on the substrate connects to the firing elements and a second circuit on the cartridge connects to the first circuit for transmitting firing signals to the ink firing elements at a frequency greater than 9 kHz. When operating the print cartridge, the substrate is able to dissipate more heat, since the ink flowing across the back of the substrate and around the edges of the substrate acts to draw heat away from the back of the substrate.

摘要： The use of lumped resistive elements (28) in an ink feed channel (10) between an ink-propelling element, such as a resistor, (12) and an ink supply plenum (14) provides a means of achieving resistive decoupling and meniscus resonance control with a minimum of deleterious side effects and design compromises typical of prior art solutions. A secondary constriction (30) in the ink feed channel is defined by a width W.sub.2 sufficient to provide physical support for the resistive elements while avoiding resistance to ink refill. The printhead further comprises lead-in lobes (38) for assisting in purging any bubbles in the ink. The lobes are disposed between the projections and the plenum chamber and separate one pair of projections from a neighboring pair.
摘要翻译：在油墨推进元件（例如电阻器）（12）和供墨气室（14）之间的供墨通道（10）中使用集总电阻元件（28）提供了实现电阻去耦和弯液面共振的手段控制与现有技术解决方案的典型的最小的有害的副作用和设计折中。供墨通道中的次级收缩（30）由宽度W2限定，足以为电阻元件提供物理支撑，同时避免对油墨再填充的抵抗。打印头还包括用于帮助清除墨水中的任何气泡的引入凸片（38）。凸起布置在突起和增压室之间，并且将一对突起与相邻的对分开。
