摘要： A pump includes two opposing plates having a space there between to define a secondary fluid passage. A first aperture is formed through the first plate and a second aperture is formed in the second plate to define a primary fluid channel extending across the secondary fluid channel. A heater on the second plate moves primary fluid through the primary fluid channel due to the Marangoni type effect. A heater on the first plate causes a meniscus to enlarge to thereby form a drop of fluid ejected out of the primary fluid channel.
摘要翻译：泵包括两个相对的板，其间具有限定第二流体通道的空间。第一孔通过第一板形成，并且第二孔形成在第二板中，以限定延伸穿过次级流体通道的主要流体通道。由于Marangoni型效应，第二板上的加热器使初级流体通过主流体通道移动。第一板上的加热器使得弯液面变大，从而形成从主流体通道排出的一滴液体。

摘要： An ink jet printer is provided having a printhead defining a plurality of orifices for ejecting ink droplets. The printer comprises a source of cleaning fluid, a cleaning member having a surface partially dipped in the cleaning fluid, a first drive mechanism to move the cleaning member surface creating a flow of cleaning fluid on the surface and a second drive mechanism to advance the printhead and the cleaning member surface into a proximate and separate relation with the cleaning member surface wherein at least one of the orifices of the printhead enters the flow of cleaning fluid wherein the print head and the cleaning member surface are separated by gap of between 0.1 mm and 2.54 mm.

摘要： A drop on demand microfluidic ink jet printing system includes an ink flow chamber having a nozzle opening in a wall of the flow chamber through which ink droplets are ejected when ink in the flow chamber is at or above a predetermined positive pressure. An inlet channel opens into the flow chamber to supply thermally-responsive ink to the flow chamber at or above the predetermined pressure. A microfluidic outlet channel communicates the flow chamber with a low pressure ink reservoir such that thermally-responsive ink is normally transported from the flow chamber at a flow velocity sufficient to maintain ink in the flow chamber at a pressure less than the predetermined positive pressure. A valve selectively restricts the flow of the thermally-responsive ink through the microfluidic outlet channel sufficiently to cause an increase in ink pressure in the flow chamber to at least the predetermined positive pressure, the valve including a heater in contact with at least a portion of the associated microfluidic outlet channel, whereby the viscosity of the thermally-responsive ink can selectively be increased by heat from the heater to restrict the flow of the thermally-responsive ink from the flow chamber such that an ink droplet is ejected through the nozzle opening.
摘要翻译：按需微型喷墨打印系统包括墨水流动室，其具有在流动室的壁中的喷嘴开口，当流动室中的墨水处于或高于预定的正压时，通过该喷嘴开口喷射墨滴。入口通道通向流动室，以在预定压力或高于预定压力的情况下向流动室供应热响应性油墨。微流出口通道将流动室与低压储墨器连通，使得热响应性油墨通常以足以将流动室中的墨维持在小于预定正压力的压力的流速从流动室输送。阀选择性地限制热响应性油墨通过微流体出口通道的流动，足以使流动室中的油墨压力增加到至少预定的正压，该阀包括与至少一部分相关联的微流体出口通道，由此热响应性油墨的粘度可以通过来自加热器的热量而选择性地增加，以限制来自流动室的热响应性油墨的流动，使得墨滴通过喷嘴开口喷射。

摘要： Image forming system and system. The method comprises a transducer for pressurizing and depressurizing an ink body so that an ink meniscus alternately extends from the ink body as the ink body is pressurized to form a neck portion thereof and retracts as the ink body is depressurized. An ink droplet separator is is in communication with the neck portion of the meniscus for lowering surface tension of the neck portion of the meniscus. In this regard, the droplet separator lowers the surface tension of the meniscus as the meniscus extends from the ink body. The extended meniscus severs from the ink body to form an ink droplet as the droplet separator lowers the surface tension of the neck portion to a predetermined value and as the ink meniscus retracts during depressurization of the ink body.
