Abstract: A method of producing a multilayer system comprises depositing a seed layer (4) of copper on an electrically insulating substrate (2). A resist is formed on the copper seed layer (4), and the seed layer is electroplated with copper to produce a desired conductor pattern (8). An air firing dielectric (10) is screen printed over the pattern (8) and the exposed parts of the seed layer (4) are fired in air. The outer skin of the pattern is oxidised as is also the whole of the seed layer other than where it underlies the copper pattern. The oxidised regions of the copper both form a firm bond with the dielectric and inhibit the migration of oxgen into the inner regions of the conductor pattern (8). Also the oxidation of the seed layer renders it non-conductive and therefore obviates the need for its removal. Through holes 12 produced in the dielectric enable electrical connection to the pattern (8).

Abstract: In order to increase the efficiency of radiation sensitive cells, a monolithic stacked device is constructed comprising a plurality of sub-cells adjusted for different bands of radiation. The interconnection between these sub-cells has been a significant technical problem. The invention provides an interconnection which is a thin layer of high ohmic conductance material formed between the sub-cells. Such a layer may tend to form beads which serve as a shorting interconnect while passing a large fraction of the radiation to the lower sub-cells and permitting lattice matching between the sub-cells to be preserved.

Abstract: 57 An optical recording medium, such as a laser disc or card, comprises a substrate supporting a layer of recording material for storing data as a multiplicity of bits, eg in binary code with the presence or otherwise of a thermally formed pit or other positive mark at each target (single bit) position providing a readable recording of the two binary states. the improvement residing in the division of the recording layer into a multiplicity of finite small number of bits of information, eg 1-16 bits but preferably 1 bit, each area being defined by an optically detectable discontinuity around at least part of its periphery. The precise location of each target position can be found by detecting the discontinuity at the edge of each area using tracking optics, and each bit written, read or erased without any degradation of signal being caused by imprecise identification of the target position. To facilitate pit erasure, each recording area may comprise a discrete portion of recording material located totally within a depressed area of the substrate surface.

Abstract: An arrangement in a silkscreen printer for positioning a second pattern (46) deriving from a first pattern (4a) provided on a stencil (4) in relation to material (2) to be printed while using a first memory arranged to store data relating to the desired position of the second pattern in relation to a reference point. The material (2) on to which the second pattern (4b) is to be printed is displaced to a printing position, in which means (5, 5') are arranged to evaluate the true position of the material. In addition means are provided for evaluating the discrepancy which would occur if the second pattern (4b) were to be applied to the material (2) in its present position. Any deviation between the true position and the desired position is evaluated and when a deviation is found to exist a stencil-holding frame (3) and/or a printing table and/or the material is, or are, displaced, or brought in some other way to a position determined by the magnitude and directional sense of the deviation, so that when applying the first pattern (4a) to the material (2) the transfer pattern (4b) is printed on the material in a position in which full or satisfactory compensation has been made for the previously established deviation. The position of the material can be evaluated with the aid of index marks (2') or part of a previously printed pattern. The position of the material (2) and/or its pattern is, or are, evaluated with the aid of one or more optical scanning and sensing means (5, 5'), preferably evaluating the position of index marks. The scanning signals (5a) obtained from the optical scanning and sensing means (5) are fed to a first unit (34) which stores scanning signals for each line in real time. These scanning signals are evaluated by a processor (2) which restructures the signals to a different from, these restructured signals being stored in a second memory (35). A stencil frame (and/or material to be printed) is arranged for displacement by means of three stepping-motors or like devices, and evaluated and calculated displacement values for each of these stepping-motors are applied thereto simultaneously and/or substantially simultaneously.

Abstract: The method according to the invention employs the principle of voltage reduction, a sequence control system ensuring the cyclic variation between differently loaded phases. In an A/D converter needed for the digital indication of the measured value, a first value which is proportional to the mean value of the difference between two rectified, integrated alternating voltages measured at different load currents serves as measured value and a second value proportional to the mean value of the difference between the two rectified integrated load currents serves as reference value. The ratio of the first to the second value is formed by the A/D conversion. <IMAGE>

Abstract: A machine for forming large cylindrical bales of hay has a baling chamber consisting of a frusto-conical crop recei­ving portion (18) and a cylindrical crop discharge portion (22). The portions are arranged end-to-end and are defined by rolls which are driven to roll the crop round on itself into the form of a bale. The bale is compacted in the dis­charge portion by being forced by incoming crop against an abutment plate (52) which is hydraulically controlled. The bale is wrapped with twine from a tying device and severed by a cutter before being released through a gate (30). The whole operation is continuous. 
     In order to produce bales with a desirable density without undue stress to the machine, a control system (58) relieves the hydraulic pressure affording the resistance to bale movement by the abutment plate (52). Sensors (60, 62) de­tect any drive torque of the machine outside a predeter­mined range and any lack of advancement of the bale, and their outputs are fed to a computer (64) controlling a re­lief valve (66) enabling the abutment plate (52) to yield and the growing bale to advance further.

Abstract: This apparatus contains a measuring device and a probe which exhibits at least one detector (Z). This detector supplies electrical pulse rates or an analog signal as a measure of the radiation intensity, a detachable cable link being provided between the measuring device and the probe. This radiation measuring apparatus is intended to reduce the previously known display fluctuations to negligible values whilst maintaining the greatest possible measuring range and the highest possible statistical accuracy and full interchangeability of probes and measuring devices. The proposed solution is that the probe exhibits a digital memory (H1, H2) and a parallel-series converter (PSW2) connected thereto, and that, in the measuring device, a processor is provided which can be connected via the line (SE) of the detachable cable link and the parallel-series converter (PSW2) to the digital memory (H1, H2). In the memory (H1, H2), correction values are digitally stored which were acquired during the calibration of the probe, both with respect to the sensitivity spread of the detector (Z) at a low radiation intensity and with respect to the spread of the saturation losses of the detector (Z) at a high radiation intensity. The processor can be used for correcting the measuring data supplied by the detector, using the stored correction values, in such a manner that when any probe of the same model is used at one and the same measuring device, the measurement error due to detector spreads is negligibly small and that when any measuring device of the same model is combined with one and the same probe, the same measurement value is always indicated. <IMAGE>
