    摘要： A fluid ejection device includes: a fluid chamber; a volume varying unit configured to vary the volume of the fluid chamber; a fluid supplying unit configured to supply fluid to the fluid chamber at a predetermined pressure; and an ejection command switching unit configured to switch a fluid ejection between a pulsed flow ejection which ejects the fluid in a pulsed manner by activating the volume varying unit and varying the volume of the fluid chamber and a continuous flow ejection which ejects the fluid with a fluid supply pressure from the fluid supplying unit higher than that in the case of the pulsed flow ejection in a state in which the volume varying unit is stopped.

    摘要： An inkjet nozzle array includes a plurality of nozzles. Each nozzle includes a chamber having an input aperture adapted to receive ink into the chamber and an output aperture through which ink is ejected from the chamber. Each chamber further includes a window adapted to receive electromagnetic radiation and operable to heat ink in the chamber responsive to the electromagnetic radiation and eject an ink droplet through the output aperture.

    摘要： Micro-fluid ejection devices, such as inkjet printheads, such as those that use a laser to eject fluid. One such micro-fluid ejection device includes a passageway plate defining a fluid chamber filled with fluid and a fluid channel to supply the fluid chamber with fluid, a top plate provided on the passageway plate, a fluid ejection hole formed through the top plate at a position corresponding to the fluid chamber, a condenser lens provided on a bottom surface of the passageway plate at a position corresponding to the fluid chamber, and laser beam irradiator capable of irradiating a laser beam through the condenser lens and into fluid contained in the fluid chamber, wherein the fluid is nucleated by the laser beam such that a vapor bubble forms and displaces a portion of the fluid, thereby ejecting a fluid droplet through the fluid ejection hole. Method of using such devices are also disclosed.

    摘要： An ink ejecting apparatus that rapidly heats a small volume of ink using radiative heating from pulsating laser light radiation (as opposed to surface conductive heating from a thin film electrical resistive heater). The laser light travels through a bubble that has been formed by a previous pulse and is absorbed by the ink (specifically designed to absorb the laser light) in the first few microns of the ink free surface. By radiatively heating the ink at a heating rate above its critical heating limit (for an example, for water at atmospheric pressure, that limit is about 0.25 MW/g), at least substantially, if not all, of the heated portion of the ink is brought to its superheat limit so as to boil instantaneously (i.e., explosively). This heating technique keeps the bubble from completely collapsing between excitations. The result is a bubble oscillating at high frequencies. This new type of bubble formation enables ink jet printers to run at resonance and at very high speeds. In addition, non-water based inks can be reliably used because the ink is no longer heated by conduction.

    摘要翻译： 一种使用来自脉冲激光辐射的辐射加热（与来自薄膜电阻加热器的表面导电加热相反）快速加热少量墨水的喷墨装置。 激光通过已经由先前脉冲形成的气泡并被无油表面的最初几微米的墨水（专门设计成吸收激光）吸收。 通过以高于其临界加热极限的加热速率（例如，对于大气压下的水，该限制为约0.25MW / g）辐射加热墨，至少基本上（如果不是全部）加热部分的墨水 被带到其过热极限，以便瞬间沸腾（即爆炸式）。 这种加热技术保持泡沫在激发之间完全崩溃。 结果是高频振荡的气泡。 这种新型的气泡形成使得喷墨打印机能够以共振和非常高的速度运行。 此外，由于油墨不再被传导加热，因此可以可靠地使用非水基油墨。
