Abstract: Accurate control of the tension of a wire electrode in a wirecut electrical discharge machine is achieved by eliminating a direct-current component from a speed difference signal between a braking section and a recovery section of the machine. The direct-current component of the speed signal which is eliminated is associated with the stretching of the wire electrode while under tension. As a result, the tension can be maintained constant dynamically as well as statically, thereby improving machining accuracy.

Abstract: In a helical scanning X-ray CT apparatus, views at an m-th slice position are obtained by interpolating 360° views in a range next to the slice position in a forward direction in which the slice position number increases and 360° views in a range next to the slice position in the backward direction, and m-th tomographic image is reconstructed based on the interpolated views at the m-th slice position. An m-th backward image (mBI) is reconstructed based on the 360° views in the range next to the m-th slice position in the backward direction without interpolation and an m-th forward image (mFI) is reconstructed based on the 360° views in the range next to the m-th slice position in the forward direction without interpolation. An (m+1)BI is obtained by BP [CONV (a - b)] on the mBI and (m+1)FI is obtained by BP [CONV (c - a)] on the mFI. Here, BP: back projection, CONV: convolution, a: a view at the m-th slice position, b: a view which is separated from "a" by 360°, and c: a view which is separated from "a" by 360°. An (m+1)th image is obtained as follows: 
 
       (m+1)I = mI + DW × {(m+1)FI - (m+1)BI}           
 
    where DW is an inclination of the coefficients of the interpolation (primary interpolation).

Abstract: The invention relates to the treatment of residues, such as grate ash, boiler ash and flydust from a waste incineration plant. It is known to collect the residues and to melt them in a melting furnace. In this case, however, metals and metal compounds remain in the slag produced, so that the re-utilisability of the latter is restricted. The invention is intended to improve the re-utilisability of the slag. A melt enriched in metals is additionally tapped from the melting furnace. A completely glassy slag which can be used, for example, in road construction is thus formed from the remainder of the melt. <IMAGE>

Abstract: A method of driving a ferroelectric liquid crystal spatial light modulator at high speed is provided. An optical pattern recognition system is also provided which is capable of recognizing or identifying two-dimensional image information in real time by using this method. 
     The driving method includes a means for driving the optically addressed type ferroelectric liquid crystal spatial light modulator without a light reflection separation layer; a means for modulating the intensities of the writing light and the reading light emitted from a laser diode and from a liquid crystal light shutter which uses a ferroelectric liquid crystal as the light modulating medium; and a means for synchronizing the spatial light modulator driving means with the means for modulating the intensities of the writing and reading light. The driving method is characterized in that it tops emitting the reading light while the write voltage is applied to the spatial light modulator. The optical pattern recognition system is a joint transform light correlator which performs the following operations: simultaneously Fourier-transforming by using coherent light at least one reference image including specified marks and at least one input image to be entered; displaying the Fourier-transformed image on the optically addressed type spatial light modulator; and Fourier-transforming the displayed Fourier-transformed image again to produce correlation peaks that correspond to the two-dimensional correlation coefficients between the reference image and the input image. The means for generating the coherent light is the laser diode, and the means for performing the Fourier transform two times is one and the same Fourier transform lens.

Abstract: During a drilling operation, the vibrational energy produced by a drill bit cutting through the earth excites a drillstring and the energy near the top of the drillstring is measured by a transducer. A reflection coefficient series is derived from the transducer output such that each reflection coefficient corresponds to a drillstring impedance discontinuity. One of the reflection coefficients is identified with a predetermined point of the drillstring and energy travel time in the drillstring is determined from the position of the one reflection coefficient in the series to the position in the series of a further coefficient.

Abstract: An integrated circuit memory is disclosed which has its primary memory array arranged into blocks and which has redundant columns, each of which can replace a column in any one of the blocks. The redundant columns are selected by way of a redundant column decoder associated with each column, each of which includes a set of address fuses into which an address is programmed, responsive to which its associated redundant column is to be selected. A plurality of redundant sense amplifiers are each associated with selected redundant columns, and are each controlled to begin the sense operation prior to propagation of the address signal through the redundant column decoders and summing circuitry. In the event that the received memory address does not match any of the programmed values in the redundant column decoders associated with a redundant sense amplifier, the sense operation is terminated. In this way, the sense operation is not delayed by the additional delay required for redundant decoding and propagation of the redundant address signals, and thus the access time penalty for accessing a redundant memory cell is much reduced or eliminated. The coupling of each redundant sense amplifier is controlled by a redundant multiplexer associated with each of the input/output terminals. Each redundant multiplexer receives the redundant column select signals from each associated redundant column decoder, and includes fuses which indicate if its input/output terminal is to be placed in communication with its associated sense amplifier upon selection of a redundant column.
