Abstract: Transparent electrical conductors comprising regions of high transparency and regions of lower transparency, but higher conductivity. This allows electrical connection through the conductor, while retaining its transparency for such applications as hand-held device display screens or transparent antennas, for example.

Abstract: This invention relates to improvements in or relating to ceramic piezoelectric ink jet print heads of the kind having an ink channel for connection to an ink ejection nozzle and to a reservoir for the ink, and a piezoelectric wall actuator which forms part of the channel and is displaceable in response to a voltage pulse thereby generating a pulse in liquid ink in the channel due to a change of pressure therein which causes ejection of a liquid droplet from the channel. Such print heads are referred to hereafter as piezoelectric ceramic ink jet print heads.

Abstract: The method of forming a pattern on a substrate is described which includes first applying a film of thermo plastic material under pressure to a substrate. Energy is then supplied to dissipate heat at the surface of the film facing the substrate thereby to bond the film to the substrate. Next, areas of the film are selectively dry etched to form a predetermined pattern on the substrate and this is followed by depositing on the substrate in the areas where the film has been dry etched, a layer of patterning material. Finally, dry removal from the substrate is effected of the film remaining thereon. There is also described the application of this method to the manufacture of an array, drop-on-demand ink jet printer.
