Abstract: A high frequency SSB radio transmitter has an envelope amplitude modulator 3 for varying the envelope of an r.f. signal source based on an error signal from envelope detectors 5, 6 detecting the envelope of the input and output waveform. 
     A signal derived from the error signal controls an amplitude modulator 10 in a subsidiary feedback loop to maintain the size of the envelopes detected by detectors 5 and 6 the same, in order that difference amplifier 7 may operate effectively. Rapid discrepancies between the detected envelopes 5 and 6 occurring within an envelope can then be corrected by amplitude modulator 3.

Abstract: A raised and fielded panel and a sheet of decorative material are brought together so that the sheet overlies the raised and fielded side of the panel and at least one of the raised and fielded side of the panel or the obverse face of the sheet of decorative material has a coating of a heat activatable adhesive, with the adhesive properties of the composition being activatable at or above about 80°C. The sheet of decorative material is then pressed against the panel at a temperature of from about 90°C to about 170°C and at a pressure of from about 1 to 6 bars for from about 5 to about 25 seconds. A decorative surface is formed on the raised and fielded side of the panel in which the adhered sheet follows the contours of the panel. The advantage of the method is that it can avoid wrinkling of the sheet of decorative material.

Abstract: A magnetoresistive (MR) sensor is disclosed which comprises a first and a second thin film layer of a magnetic material separated by a thin film layer of a non-magnetic metallic material. The first ferromagnetic layer is magnetically soft. The magnetization direction of the first layer of magnetic material is set substantially perpendicular to the magnetization of the second layer of magnetic material at zero applied field, and the magnetization direction of the second layer of magnetic material is fixed. A current flow is produced through the MR sensor, and the variations in voltage across the MR sensor are sensed due to changes in resistance of the MR sensor produced by rotation of the magnetization in the first layer of magnetic material as a function of the magnetic field being sensed. The variation of the resistance with the angle between the magnetizations of the first and second layers of magnetic material has been defined as the spin valve (SV) effect. It is also shown that, by a suitable direction of the current with respect to the fixed magnetization, the (SV) magnetoresistance can be added constructively to the usual anisotropic magnetoresistance.

Abstract: An intermediate frequency transversal equalizer (92), for use in a QAM demodulator, is described. The tap weights of the equalizer are updated in response to the demodulated signal and to pseudo - error signals, which the demodulator generates. If the locally generated carrier is not synchronised with the incoming signal, only those signals which fall into particular regions of the phase plane are used to update the tap weights. In this way, the equalizer can continue to function correctly even when the demodulator is not synchronised.

Abstract: A technique for forming metal interconnect signal lines provides for planarization of an interlevel dielectric layer. A thin layer of material which can function as an etch stop, such as a metal oxide, is formed over the interlevel dielectric. An alignment process is used to pattern and define openings through the etch stop layer where contacts to underlying conductive regions will be formed. Another insulating layer is formed over the etch stop layer, and patterned to define all interconnect signal lines. When the signal line locations are etched away, the etching process stops on the etch stop layer in regions where the signal lines will be, and continues through to the underlying conductive layer where contacts are needed. A metal refill process can be used to then form interconnects and contacts within the etched holes, followed by an anisotropic etchback to remove any metal which lies on top of the upper insulating layer. This results in interconnect and contacts having upper surfaces which are substantially coplanar with the upper insulating layer in which they are formed.

Abstract: A fully programmable, graphics microprocessor is disclosed which is designed to be embodied in a removable external memory unit for connection with a host information processing system. In an exemplary embodiment, a video game system is described including a host video game system and a pluggable video game cartridge housing the graphics microprocessor. The game cartridge also includes a read-only program memory (ROM) and a random-access memory (RAM). The graphics coprocessor operates in conjunction with a three bus architecture embodied on the game cartridge. The graphics processor using this bus architecture may execute programs from either the program ROM, external RAM or its own internal cache RAM. The fully user programmable graphics coprocessor has an instruction set which is designed to efficiently implement arithmetic operations associated with 3-D graphics and, for example, includes special instructions executed by dedicated hardware for plotting individual pixels in the host video game system's character mapped display which, from the programmer's point of view, creates a "virtual" bit map by permitting the addressing of individual pixels -- even though the host system is character based. The graphics coprocessor interacts with the host coprocessor such that the graphics coprocessor's 16 general registers are accessible to the host processor at all times.

Abstract: A method and apparatus for checkerboard printing by a liquid ink printing apparatus, such as a thermal ink jet printer, includes circuitry 56,58 for reducing video data rate in checkerboard printing by controlling the odd and even vertical print strokes of a reciprocating printhead mounted to a scanning carriage. The amount of bitmapped image data, also known as video data, is reduced by one half or more and prior to being sent to the printhead for printing checkerboard patterns. Reduction of the bitmapped image data is accomplished by a data packer circuit 56 which selects certain bits of the bitmapped image data for printing by the printhead in a checkerboard pattern. At the printhead, the bitmapped image is reconstructed by a data unpacker circuit 58 to cause selective ejection of ink from the appropriate nozzles of the printhead. Two or more passes information are printed to complete printing of the bitmapped image data.
