摘要： Described herein is a monolithic printhead formed using integrated circuit techniques. Thin film layers, including ink ejection elements, are formed on a top surface of a silicon substrate. The various layers are etched to provide conductive leads to the ink ejection elements. At least one ink feed hole is formed through the thin film layers for each ink ejection chamber. A trench is etched in the bottom surface of the substrate so that ink can flow into the trench and into each ink ejection chamber through the ink feed holes formed in the thin film layers. The trench completely etches away portions of the substrate near the ink feed holes so that the thin film layers form a shelf in the vicinity of the ink feed holes. In one embodiment, the shelf supports the ink ejection elements. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers.

摘要： A monolithic inkjet printhead formed using integrated circuit techniques is described. A silicon substrate has formed on its top surface a thin polysilicon layer in the area in which a trench is to be later formed in the substrate. The edges of the polysilicon layer align with the intended placement of ink feed holes leading into ink ejection chambers. Thin film layers, including a resistive layer, are formed on the top surface of the silicon substrate and over the polysilicon layer. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers. A trench mask is formed on the bottom surface of the substrate. A trench is etched (using, for example, TMAH) through the exposed bottom surface of the substrate and to the polysilicon layer. The etching of the polysilicon layer exposes fast etch planes of the silicon. The TMAH then rapidly etches the silicon substrate along the etch planes, thus aligning the edges of the trench with the polysilicon. A wet etch is then performed using a buffered oxide etch (BOE) solution. The BOE will completely etch through the exposed thin film layers on the topside and underside of the substrate, forming ink feed holes through the thin film layers. The trench is now aligned with the ink feed holes due to the polysilicon layer.

摘要： A printhead used to eject fluid onto a recording medium has an integrated heat-sink which is used to cool the energy dissipation elements used to propel the fluid from the printhead. The printhead is comprised of a semiconductor substrate that has been processed with thin-film layers. On top of the thin-film layers is an orifice layer that has a pattern of orifices. Fluid feed channels, on the side of the printhead opposite the orifice, supply fluid to the pattern of orifices. Within the thin-film layers are energy dissipating elements which are used to transfer energy to the fluid thereby ejecting fluid from the orifice. The fluid is transferred to the orifice opening through fluid feed slots formed in the thin-film layer adjacent to the energy dissipation elements which is exposed in the fluid feed channel. An integrated heat-sink is attached to the energy dissipation elements to remove heat to the semiconductor substrate and the fluid supply in the fluid feed channel.

摘要： A coding scheme for digital audio signals. A method of coding a unary digital audio signal is provided for compressing a set of unary digital audio signal data comprising a succession of absolute amplitude values associated with respective sample periods of the digital audio signal, the absolute amplitude values being integers of positive or zero value, representing the number of speaker elements of a unary digital loudspeaker that are to be active in a sample period. The data is compressed by calculating the numerical difference between adjacent ones of the absolute amplitude values, thereby to convert the succession of absolute amplitude values into a corresponding succession of difference amplitude values. Each difference amplitude values is expressed as a sign bit and a plurality of data bits, representing the change in the number of speaker elements of a unary digital loudspeaker that are to be active in a given sample period relative to the immediately preceding sample period. A corresponding method of decoding the compressed signal is also provided, together with associated encoding and decoding apparatuses.

摘要： A server for a merchant computer system, the server comprising: a file store for storing a range of audio/video products in respective product files; a dialogue unit having a network connection and operable to invite and receive a client selection from among the products via the network connection; a product reader for reading the product files to generate a digital audio/video signal; a digital signal processing unit having an input connectable to receive the digital audio/video signal from the product reader, a processing core operable to apply a defined level of content degradation to the digital audio/video signal, and an output connected to output the degraded digital audio/video signal from the processing core to the network connection. It is therefore possible for a content provider to change the characteristics of an audio or video data stream supplied over a network to a potential purchaser in a controlled and variable manner. The amount of degradation is sufficient to enable a potential purchaser to appreciate the characteristics of the audio or video product, whilst reducing the perceived quality.
