摘要： A drop-on-demand piezo-electric printhead has channel walls defined by piezo-electric material (10) with electrodes (26) along the length thereof. In portions of the channels which are open to an ink supply conduit, the piezo material is locally disabled, e.g. by reducing the width of the electrode or by interposing a material (40) of lower dielectric constant between the electrode and the piezo material. A lower capacitive load results.

摘要： A process for the passivation of the channel walls of an ink jet print head channel of ceramic piezoelectric material and which enables the deposition of a continuous coating on the walls of a deep channel without depolarising the material comprises depositing a coating comprising inorganic material by: (a) providing an ink jet print head component containing said channel and (b) while maintaining the bulk temperature of the actuating component which contains said channel at a temperature of below 200 DEG C and at which not more than 30 % depolarisation of the material occurs during passivation, exposing the surface of the channel walls to be passivated to a homogenised vapour of the coating material, said vapour having undergone multiple scattering during transport thereof from the source of the vapour to said surface. The process may be employed to deposit a plurality of layers which may be of differing composition, and the invention also provides ceramic piezoelectric ink jet print heads the channels walls of which have been coated with particular combinations of layers of differing compositions.

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： 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。

摘要： An ink jet print head with a closest spacing in the vertical matrix direction of p and with a closest spacing in the horizontal matrix direction of q, has parallel ink channels, piezoelectric side walls, nozzles, and a common ink manifold. The channels are arranged in N groups which are successively enabled for droplet ejection and the head is inclined at an angle beta to the vertical matrix direction given by formula (I) where i is a positive integer. This provides an increase in the operating frequency and avoids the need for offsetting the nozzles of one group with respect to another.

摘要： In a method of colour printing using arrays of threshold value for interpolating between grey levels, the threshold values for each of the colours are provided by defining rows of threshold values, with each row having the same repeating sequence but offset. The repeating sequences are different for each colour but the offset is the same for all colours. The arrays best take the form Tij =(i*p -j*q )%(r S).

摘要： A nozzle in a nozzle plate for an inkjet printhead is formed by directing a laser beam at a nozzle plate. Accurate control of the divergence of the beam is achieved by splitting the beam into sub-beams, each sub-beam having divergence with an origin lying apart from the point at which the beam is created by splitting, and thereafter recombining the sub-beams. Greater accuracy in the taper and inlet shape of the manufactured nozzle is thereby obtained.

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.
