  • Power distribution in a thermal ink jet printhead
    Patent number: 8444255
    Abstract: A thermal inkjet printhead may include a substrate and a resistive layer. A thermal resistor may be formed in the resistive layer. A first metal layer may be between the substrate and a resistive layer having a thickness to form a power bus. A dielectric layer may be between the first metal layer and the resistive layer.
    Type: Grant
    Filed: May 18, 2011
    Date of Patent: May 21, 2013
    Assignee: Hewlett-Packard Development Company, L.P.

  • Fluid ejection device
    Publication number: 20070289132
    Abstract: A fluid ejection device comprises a first heater element and a second heater element spaced a first distance from the first heater element. A first drive transistor is associated with the first heater element and a second drive transistor is associated with the second firing heater element. The second drive transistor is spaced a second distance from the first drive transistor. The second distance is different from the first distance.
