摘要： A snap-through thermal actuator for a micro-electromechanical device is provided. The snap-through actuator includes a base element formed with a depression having opposing anchor edges which define a central plane. A deformable element, attached to the base element at the opposing anchor edges, is constructed as a planar lamination including a first layer of a first material having a low coefficient of thermal expansion and a second layer of a second material having a high coefficient of thermal expansion. The deformable element is formed to have a residual shape bowing outward from the central plane in a first direction away from the second layer. The snap-through thermal actuator further includes apparatus adapted to apply a heat pulse to the deformable element which causes a sudden rise in the temperature of the deformable element.

摘要： A continuous inkjet printer in which a continuous ink stream is deflected at the printhead nozzle bore without the need for charged deflection plates or tunnels. The printhead includes a primary ink delivery channel which delivers a primary flow of pressurized ink through an ink staging chamber to the nozzle bore to create an undeflected ink stream from the printhead. A secondary ink delivery channel adjacent to the primary channel is controlled by a thermally actuated valve to selectively create a lateral flow of pressurized ink into the primary flow thereby causing the emitted ink stream to deflect in a direction opposite to the direction from which the secondary ink stream impinges the primary ink stream in the ink staging chamber. A method of fabricating the printhead includes layering of the thermally actuated valve over the secondary ink delivery channel formed in a silicon substrate and creating the ink staging chamber over the delivery channels with sacrificial material which is later removed through the nozzle bore etched into the chamber wall formed over the sacrificial material.

摘要： A continuous color ink jet print head (40) for an electronic printing device is composed of a nozzle (42), pressurized ink sources (46, 48), and a print head surface (50) having channels (61, 62, 64, 66) disposed therein such that each channel (61, 62, 64, 66) is in communication with the nozzle (42). The continuous color ink jet print head (40) also includes a microvalve (52, 56) disposed within each of the channels (61, 62, 64, 66) such that each channel (61, 62, 64, 66) is connected through the microvalve (52, 56) to a pressurized ink source (46, 48), thereby permitting ink from the pressurized ink source (46, 48) to flow through the channel (61, 62, 64, 66) and thereafter be ejected from the nozzle (42) when the pressurized ink source (46, 48) has attained a particular threshold pressure. The microvalve (52, 56) itself is a thermally activated microvalve (52, 56) that permits colored patterns of dots of varying intensities to be ejected from the nozzle (42) onto a receiver at a constant rate, thereby maintaining a static ink printed pixel size. By selectively controlling the length of time the microvalve (52, 56) is actuated, a range of colored inks is permitted to be ejected from the nozzle (42) onto the receiver.
