    摘要： An improved heater chip for an ink jet print head, the chip including an active heater array and an inactive heater array located adjacent to and extending away from the end of the active heater array. The inactive heater array provides a region adjacent the end of the active heater array that is substantially planar, and also provides a plurality of current paths which reduces energy differences between heater resistors adjacent the end of the active heater array and other heater resistors in the heater array.

    摘要： A micro-fluid ejecting device includes a semiconductor substrate, a plurality of fluid ejection elements formed on the semiconductor substrate, and a plurality of nonvolatile programmable memory devices for storing information related to the operation of the micro-fluid ejecting device. The programmable memory devices, which are at least partially embedded in the semiconductor substrate, each include a source region and a drain region formed in the semiconductor substrate. The source and drain regions have a conductivity type which is opposite the conductivity type of the semiconductor substrate. An insulative layer is formed on the semiconductor substrate over the source region and drain region. A floating gate region is formed on the insulative layer and is spatially disposed between the source region and drain region. The floating gate region is electrically insulated from the source and drain regions by the insulative layer. Electrical contacts are connected to the source region and the drain region. The programmable memory devices collectively provide a high density of memory bits embedded on the substrate for storing information about the micro-fluid ejecting device.

    摘要： Power is provided from one portion of a printer, such as a printer electronics module, to another portion of the printer, such as a printhead. Logic signals produced in a first electronic module of the printer are transmitted to a second electronics module of the printer. A power signal is derived from the logic signals without interfering with the magnitude or duration of logic signals, and the logic power signal is applied to power the second electronic module without having a separate dedicated power line.
