Abstract: A method of assembling a multilayer laminate interconnection board, particularly boards in which each layer preferably includes copper conductors (16) on polyimide film layers (14), involves adhesively joining individual layers of wired film initially onto an auxiliary pin carrier substrate (20) and then onto a previously laminated layer. After each layer is aligned and adhesively joined to the immediately preceeding layer, holes are formed through the layer. Metal is deposited into the holes for electrically connecting conductors on the top surface of the last layer to a via located on the immediately preceeding layer. The process is repeated for each layer of the multilayer laminate interconnection board until the entire board is completely assembled. Alternatively, layers con­taining preformed and metalized holes at the location of a respective via in a particular layer are aligned and adhesively laminated.

Abstract: A process for the gaseous reduction of iron ore to sponge in a vertical shaft, moving bed reactor wherein a hot gaseous mixture of hydrogen and carbon monoxide generated by the reformation of methane or natural gas, is used to reduce the ore without the need for an external catalytic reformer. A reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions is established with the product sponge iron in the reduction reactor being used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom. High overall process thermal efficiency and operating cost effective­ness is achieved by also establishing a steam and/or hot water loops wherein all process steam requirements are met through the utilization of hot water discharge from the quench cooler and advantageously also the generation of steam by the reclamation of waste heat from spent hot reducing gas leaving the reactor, thereby eliminating the need for importing costly process steam.

Abstract: There is provided an image processing apparatus such as facsimile apparatus or digital copying machine for digitizing image data into two values or multi-values. The apparatus comprises: an input device to input data of a target pixel to be digitized; a calculating circuit to obtain an average density value of a predetermined region; a digitizing circuit such as a binarizing circuit for digitizing or binarizing the target pixel data on the basis of the average density value obtained by the calculating circuit; and a correction circuit to correct a difference which occurs upon digitization by the digitizing circuit. The calculating circuit calculates the average density value mi of the predetermined region when the target pixel data was binarized to 1 and the average density value m 2  of the predetermined region when the target pixel data was binarized to 0 by using a predetermined weighting mask. The digitizing circuit binarizes the target pixel data by using (m 1  + m 2 )/2 as a threshold value. When the difference between the target pixel data and the average density value is within a predetermined value, the difference is corrected, so that an image of excellent gradation can be reproduced. When it is equal to or larger than the predetermined value, the difference is not corrected, so that the resolution of a character portion such as an edge portion can be improved.

Abstract: A digital loop filter translates a multi-bit phase error input into a high resolution control signal utilizable as an advance-retard control for a multi-phase clock generator. The digital filter couples the multi-bit phase error input to the clock generator via a pulse density modulation (PDM) accumulator, providing multi-phase adjustment in a single sample clock cycle based on the overflow or underflow of the PDM accumulator. Variable PDM cycles are used to control loop filter bandwidth, permitting adjustable capture sequences. Thus, real proportional control of the multi-phase clock generator is limited only by the word size of the phase error input.

Abstract: For projecting a photomask (5) pattern on a wafer (10) using a projection optical system (1-4,6) having a short wavelength light source (1) and a high numerical aperture, a method for projection exposure is proposed, by which a focal margin may be improved to achieve stable resolution and improved throughput. It is assumed for example that three-stage sequential light exposure is performed by setting an image plane at three positions, namely at a center focal position which is a mean height position of highs and lows of the water surface step difference and plus and minus focal positions offset a predetermined amount on each side of the center focal position. If light exposure is performed at each of these positions with an exposure light volume equal to one-third of the total exposure light volume, the focus margin becomes smaller than that in the case of the two-stage light exposure. By using a relatively small exposure light volume at the center focal position according to the present invention, the focal margin may be enlarged, although the synthesized light intensity contrast becomes minimum at the center focal position. The same effect may also be achieved by continuous light exposure with the constant exposure light volume using a relatively high speed of movement of the image plane at the center focal position for improving the throughput.

Abstract: An absorbent material to be used as cat litter and which comprises a loose granulated or grainy material with capabilities to collect, bind and possibly decompose the matter to be absorbed. The absorbent material is prepared on the basis of a waste product from flue-gas purification, especially flue-gas desulphurification. The waste product is the result of spray absorption in connection with flue-gas purification from for instance power plants burning fuel with a high sulphur content. As a result, a starting material may be used which is available in large quantities with almost uniform composition. The starting material is thus very inexpensive. 
     A method for the prepartion of the absorbent material where the waste product from the flue-gas purification is firstly granulated and then admixed with water. Subsequently further granulation takes place followed by powdering, or the granulate is subjected to treatment in a Rulator. Finally, the granulate is dried. As a result, the preparation is particularly inexpensive and the quality of the product is uniform.
