摘要： Where material is to be removed from an element (4) of an inkjet printhead having a surface (6) intended to form part of the external surface of the printhead, at least part of the material being removed by ablation using a high energy beam directed at said surface, a protective layer (10) is applied to be in sealing engagement with the surface. The layer is believed to protect the surface from high energy free radicals liberated during the ablation process.
摘要翻译：如果要从具有旨在形成打印头的外表面的一部分的表面（6）的喷墨打印头的元件（4）去除材料，则至少部分材料通过消融使用高能量光束在所述表面上，施加保护层（10）以与表面密封接合。该层被认为保护表面免受在消融过程中释放的高能量自由基。

摘要： Ink jet printhead (8) components are formed initially by bonding together a grooved base wafer (10) and a suitable cover wafer (12), the area of the bonding wafer assembly being sufficient to provide a 14 x 14 array of components. Using a datum formation, the wafer assembly is divided into strips and linear processing steps are conducted, such as applying nozzle plates (14) and laser ablating nozzles. Each strip can then be divided to form separate printhead components.

摘要： As a step in the manufacture of an ink jet printer, a cover (16) is adhesively bonded to a piezoelectric layer (10) having parallel grooves (20) which will serve as ink channels in the finished printer. Mating surfaces are prepared, excess adhesive is applied and bond pressure exerted until surface extremities of the two surfaces come into contact, producing a bond layer of 2 mu m or less. To ensure that the flow distance of excess adhesive is uniform over the bond plane, grooves (32) are cut at the margin (30) of the piezoelectric layer.

摘要： In droplet deposition apparatus comprising one or more independently actuable ink ejection chambers, electrical signals are applied to reduce variation in the temperature of the droplet fluid between chambers and with variations in droplet ejection input data. Short potential difference pulses, suitable for influencing the temperature of the droplet fluid in a chamber, can be generated by application of longer duration voltages to ink chamber actuation means.

摘要： The selected ink channels of a drop-on-demand ink jet printer are caused to expand and then contract, ejecting ink droplets by the application of unipolar voltages first to selected channels and then to non-selected channels. Further unipolar voltages, delayed in time by 2L/c and scaled by a pressure wave reflection coefficient r of the nozzle, effect prompt cancellation of residual pressure waves so that adjacent channels are ready for actuation with minimum delay.
摘要翻译：使按需喷墨打印机的所选择的墨水通道首先通过单极电压施加到所选择的通道，然后到未选择的通道而膨胀然后收缩，喷射墨滴。进一步的单极性电压延迟2L / c，并通过喷嘴的压力波反射系数r进行放大，可以及时消除残留压力波，从而相邻通道准备好以最小的延迟进行启动。
