摘要： A droplet generator is provided that is particularly adapted for generating micro droplets of ink on demand in an inkjet printhead having a plurality of nozzles. The droplet generator includes a droplet separator formed from the combination of a droplet assistor and a droplet initiator. The droplet assistor is coupled to ink in each of the nozzles and functions to lower the amount of energy necessary for an ink droplet to form and separate from an ink meniscus extending across the nozzle outlet. The droplet assistor may be, for example, a heater or surfactant supply mechanism for lowering the surface tension of the ink meniscus. Alternatively, the droplet assistor may be a mechanical oscillator such as a piezoelectric transducer that generates oscillations in the ink sufficient to periodically form convex ink meniscus across the nozzle outlets, but insufficient to cause ink droplets to separate from the outlets. The droplet initiator cooperates with the droplet assistor and selectively causes an ink droplet to form and separate from the ink meniscus. The droplet initiator may be, for example, a thermally-actuated paddle. The droplet separator increases the speed and accuracy of ink micro droplets expelled from the printhead nozzles.

摘要： A liquid drop emitter, such as an ink jet device, for emitting a series of liquid drops at high frequency is disclosed. The drop emitter comprises a liquid-filled chamber having a nozzle, a thermo-mechanical actuator for applying pressure to liquid at the nozzle, means for heating the thermo-mechanical actuator in response to electrical pulses, and a controller for determining the parameters of the electrical pulses. The method of operating comprises determining a nominal electrical pulse having a nominal energy E0, a nominal pulse duration TP0, which causes the emission of at least one drop at a sustained period of repetition TC. The method of operating further determines a steady state electrical pulse having energy E0, a steady state pulse duration TPss, which, when applied to the electroresistive means does not cause the emission or weeping of the liquid from the nozzle. The method applies to the means for heating, during every period of time TC, a nominal electrical pulse to emit at least one drop, or a steady state electrical pulse, so that an average power PAVE, where PAVE=E0/TC, is applied to the liquid drop emitter in order to maintain a steady state thermal condition.

摘要： A method for manufacturing a mechanical grating device is presented. The device consists of a plurality of parallel-suspended ribbons that are deformed using, for example, an electrostatic force to actuate alternate ribbons. Actuation is a deformation of the ribbon resulting from an applied voltage to affect the height of the ribbons above a substrate. The method for manufacturing a mechanical gating device comprises the steps of: providing a spacer layer on top of a protective layer which covers a substrate; etching a channel entirely through the spacer layer; depositing a sacrificial layer at least as thick as the spacer layer; rendering the deposited sacrificial layer optically coplanar by chemical mechanical polishing; providing a tensile ribbon layer completely covering the area of the channel; providing a conductive layer patterned in the form of a grating; transferring the conductive layer pattern to the ribbon layer and etching entirely through the ribbon layer; and removing entirely the sacrificial layer from the channel.

摘要： A continuous liquid ejection system includes a substrate defining a liquid chamber. An orifice plate, affixed to the substrate, includes a MEMS transducing member. The MEMS transducing member includes a first portion anchored to the substrate and a second portion extending over and free to move relative to the liquid chamber. A compliant membrane, positioned in contact with the MEMS transducing member, includes an orifice and a first portion covering the MEMS transducing member and a second portion anchored to the substrate. A liquid supply provides a liquid to the liquid chamber under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane. The MEMS transducing member is selectively actuated to cause a portion of the compliant membrane to be displaced relative to the liquid chamber to cause a drop of liquid to break off from the liquid jet.
