摘要: An apparatus for a thermal actuator for a micromechanical device, especially a liquid drop emitter such as an ink jet printhead, is disclosed. The disclosed thermal actuator comprises a base element and a cantilevered element including a thermo-mechanical bending portion extending from the base element and a free end portion residing in a first position. The thermo-mechanical bending portion has a base end width, wb, adjacent the base element and a free end width, wf, adjacent the free end portion wherein the base end width is substantially greater than the free end width. The thermal actuator further comprises apparatus adapted to apply a heat pulse directly to the thermo-mechanical bending portion causing the deflection of the free end portion of the cantilevered element to a second position. The width of the thermo-mechanical bending portion may reduce substantially monotonically as a function of the distance away from the base element or in at least one step reduction. The apparatus adapted to apply a heat pulse may comprise a thin film resistor. Alternatively, the thermo-mechanical bending portion may comprise a layer of electrically resistive material having a heater resistor formed therein to which is applied an electrical pulse to cause rapid deflection of the free end portion and ejection of a liquid drop.

摘要: A process including: jetting at least one ink from a color ink set onto a substrate to form a first pixel; and jetting a heliosing ink onto the first pixel to form a heliosed pixel, wherein the first pixel is substantially free of resolution diminution in the heliosed pixel. The process can also be accomplished in the reverse jetting order, that is, jetting a heliosing ink onto a substrate to form a patent or latent heliosed first pixel; and jetting at least one ink from a color ink set over the heliosed first pixel to form a heliosed color pixel, wherein the resolution in the heliosed pixel is substantially the same as the resolution in the absence of the heliosing ink. The heliosing ink formulations can include, for example, one or more of: an obscurant, a bleachant, or a penetrant. The processes of the present invention can be used to create heliographic images.

摘要: A magnetically actuated ink jet printing device for use in an ink jet printer ejects ink droplets by deforming a diaphragm with the force generated on an electrode in a magnetic field when an electric current pulse is applied thereto. In one embodiment, the diaphragm of the device is provided by anisotropically etching a silicon substrate with an etch stop which provides a thin membrane of silicon material for use as the diaphragm. An electrode having an input and output terminal is patterned over the diaphragm and a sacrificial layer is deposited over the silicon substrate surface containing the diaphragm. The sacrificial layer is patterned to subsequently provide the ink ejection chamber over the diaphragm. A patternable layer is deposited over the silicon substrate surface including the sacrificial layer and patterned to provide the nozzles and expose the electrode terminals. The sacrificial layer is removed and an ink supply is connected to the space previously occupied by the sacrificial layer. Magnetic field generating means having a predetermined magnetic field strength are placed adjacent the device, and electric current applied to the electrode terminals in a predetermined direction relative to the magnetic field produces a force necessary to deform the diaphragm and eject an ink droplet from the nozzles of the printing device.

摘要: An energy efficient thermoremanent magnetic imaging method and apparatus comprising a moving magnetic recording medium which is passed through a nip formed by a thermal printhead and a pressure roller, so that the magnetizable surface of the recording medium is in pressure contact with the heating elements of the thermal printhead. The recording medium is pre-magnetized prior to entry in the nip and passed through a magnetic field of lower strength and opposite polarity at the nip. Small areas or pixels of the pre-magnetized recording medium are heated by the thermal printhead in image configuration and allowed to cool in the presence of the magnetic field at the nip. The magnetic poles of the imagewise pixels are switched, forming fringe fields between the pixels and pre-magnetized background areas. The pixels with the switched magnetic poles are spaced from each other to prevent the fringe fields from forming around the periphery of clusters of pixels and collapsing in between some or all of the pixels making up the cluster.
