Abstract: Printheads and methods for forming printheads are described herein. In one example, a printhead includes a single resistor window in a conducting layer within the printhead. The printhead also includes a number of resistors formed in a resistor film deposited over the single resistor window. The resistors have two different widths, and each of the two different widths ejects a different droplet size when energized.

Abstract: Printheads and methods for forming printheads are described herein. In one example, a printhead includes a number of drop generators, wherein a pitch between each adjacent drop generator is substantially the same, and the drop generators alternate between a high drop weight (HDW) drop generator and a low drop weight (LDW) drop generator. The printhead also includes a flow channel from an ink source leading into an ejection chamber associated with each drop generator, wherein the flow channel comprises an inflow region proximate to the ink source, wherein an area of the inflow region is adjusted to control the flux of ink into the ejection chamber.

Abstract: An example microfluidic device comprises a substrate having a first surface and a cover layer above the first surface. The cover layer and the first surface form a microfluidic channel and a chamber. The example microfluidic device further comprises a functional port in the cover layer over the chamber and at least one developer port in the cover layer over the microfluidic channel. The developer port is above a portion of the microfluidic channel that is not proximate to the functional port.

Abstract: An improved circuit breaker locking device is provided that is capable of locking any one of a set of push-pull circuit breaker actuators having shaft and top annular flanges of different diameters. The device includes a pair of opposing body sections, each having a proximal and a distal recess arranged in tandem, and an elastic joining member that joins the opposing body sections together. The proximal and distal recesses of the opposing body sections are sized to capture without frictionally gripping the largest diameter cylindrical shaft section and the largest annular flange of the set of actuators when the body sections are joined together around the actuator. The interface between the proximal and distal recesses is sized to interfere with and prevent passage of the smallest annular flange of all of the actuators.

Abstract: A fluid ejection device includes a fluidic layer assembly mounted to a substrate, the fluidic layer assembly having a raised portion formed on a side that faces away from the substrate. A first nozzle is formed through a portion of the fluidic layer assembly other than the raised portion, and a second, larger nozzle is formed through the raised portion. A method of fabricating a fluid ejection device includes applying a first layer of a photoresist material to a substrate and a second layer of a photoresist material to the first layer. A sequence of exposures defines a first region of soluble material in the first layer that becomes the first nozzle and second and third regions of soluble material in the first and second layers, respectively, that jointly become the second nozzle. A region of insoluble material in the second layer becomes the raised portion.
