Abstract: A resistor array including a series of spaced first conductor members, a series of initially substantially non-conductive switches respectively connecting adjacent first conductor members to one another, at least one second conductor member in spaced relation to the first conductor members, and a series of resistors extending from respective first conductive members to the at least one second conductor member.

Abstract: A method and apparatus for assembling an inkjet printhead is disclosed. The apparatus comprises one or more microheater resistors and a material, which can be reflowed by use of the heat generated by the microheater, disposed proximate to the heater resistor. The microheater resistor comprises a heater resistor with an input port and an output port. A first electrical conductor, coupled to the input port of the heater resistor, receives a first voltage and a second electrical conductor, coupled to the output port of the heater resistor, receives a second voltage. A curing effect in the adhesive is produced by heat generated in the heater resistor when electrical current flows through the resistor in response to an application of a first voltage to the first electrical conductor and a second voltage to the second electrical conductor.

Abstract: A carrier frame having an aperture and a nozzle plate disposed on the carrier frame and positioned over the aperture is described. The nozzle plate has at least one nozzle formed between opposing surfaces of the nozzle plate. The carrier frame and the nozzle plate are made from materials having dissimilar thermal expansion coefficients such that the carrier frame has a thermal expansion coefficient that is less than the thermal expansion coefficient of the nozzle plate. The nozzle plate is staked to the carrier frame and then baked so that the nozzle plate shrinks during the baking process thereby becoming taught and under a state of tensile stress. The nozzle is formed in the nozzle plate after the baking process by laser ablation, for example. The nozzle thus formed has a true bore due to the taught nozzle plate and the opposed surfaces of the nozzle plate being parallel to each other.

Abstract: A ticket including a base member, a discolorable member carried by the base member, and a discoloration system carried by the base member. The discoloration system is initially configured such that the discoloration system selectively discolors a first predetermined portion of the discolorable member in response to the application of a first energy pulse without discoloring a second predetermined portion of the discolorable member. The discoloration system is also adapted to be reconfigured by the first energy pulse such that the second predetermined portion of the discolorable member will be discolored in response to the application of a second energy pulse.

Abstract: In one embodiment of the invention, a flexible tape has formed on it conductors for being connected to a printhead substrate. The conductors on the tape are coated with an insulating layer, and exposed ends of the conductors extend from the layer. A headland is formed on a plastic print cartridge for receiving the printhead substrate having the exposed conductors extending from one or more edges of the printhead substrate. An adhesive bead is formed on the headland so that when the printhead is properly positioned on the headland, the adhesive contacts the conductors to encapsulate and insulate one exposed side of the conductors. A second adhesive or encapsulant bead is deposited over the opposite side of the conductors to encapsulate and insulate the remaining exposed regions of the conductors. In this manner, the combined insulating action of the insulating layer and the two insulating adhesive beads prevents the conductors from being shorted together by ink which may flow in the vicinity of the conductors.
