    摘要： This bubblejet device has integrated into it a number of heater resistors and a temperature sensor which operate in conjunction with a temperature regulating circuit to heat the chip to its optimum operating temperature within seconds of turn-on, and thereafter maintain that temperature regardless of local temperature variations. The precise temperature regulation of the array improves print quality.

    摘要： An inkjet printhead addressing and firing design which minimizes voltage drop differential occurring on a power bus which supplies power to fire individual ink jets due to current loads needed to fire the individual ink jets. The voltage drop differential can be reduced in part by firing a group of individual jets which are spaced out over the entire length of the array instead of firing a group of adjacent jets. Spacing of the firing jets will insure that less than an entire amount of current needed to fire a group of jets will be needed in the center of the bus. Reducing the amount of current needed to travel the length of the bus reduces the voltage drop differential on the bus caused by current conduction along the bus.

    摘要： A layout of a MOSFET current driver is disclosed which improves the fabrication yield and the current drive capability over that of the prior art while keeping the layout area the same as the prior art. In this design, the gate is laid out to have a lateral serpentine pattern rather than a vertical serpentine pattern to create a larger gate in order to improve the current drive capability. In addition, the contacts for the drain and the contacts for the source are removed from the gate layout area which facilitates condensing the gate layout and increasing the size of the gate. Also, this design has only two metal strips: one for the drain and one for the source of the MOSFET current driver. The two metal strips substantially overlap the serpentine patterned gate. Having only two metal strips reduces the spaces between the metal strips to one space thereby reducing the probability of having a short or a defect and improving the fabrication yield.

    摘要翻译： 公开了MOSFET电流驱动器的布局，其提高了现有技术的制造产量和电流驱动能力，同时保持布局面积与现有技术相同。 在这种设计中，门被布置为具有侧向蛇形图案，而不是垂直的蛇形图案以产生更大的栅极，以便提高电流驱动能力。 此外，用于源极的漏极和触点的触点从栅极布局区域移除，这有利于栅极布局的集中和增加栅极的尺寸。 此外，该设计只有两个金属条：一个用于漏极，一个用于MOSFET电流驱动器的源极。 两个金属条基本上与蛇形图案化的栅极重叠。 只有两个金属条将金属条之间的空间减小到一个空间，从而减少了短或缺陷的可能性并提高了制造成品率。
