Patent EP-0352975-A2 (EP)
Inventor: JEWELL TATIANA EMELIANOVNA
IPC: G03F7/20
Filed: 1989-07-20
Abstract: A lithography system is disclosed which is capable of doubling the spatial frequency resolution associated with conventional systems. A spatial filter (e.g., 20), positioned to intercept the Fraunhofer diffraction pattern of the mask (e.g., 18) being exposed, is configured to prevent certain orders of the diffraction pattern (in most cases the 0-order and ±2nd, 3rd, ... orders) from reaching the wafer's surface. The remaining orders reaching the wafer surface (in most cases the ± first-order beams) will produce a cos-type interference pattern with a period half of that if the mask grating were imaged without spatial filtering. Therefore, for a system with a given magnification factor m, a mask grating with a period p will be exposed on the wafer surface as a grating with a period of p′=pm/2. Advantageously, the spatial filtering technique of the present invention allows for a variety of different structures (conventional gratings, chirped and phase-shifted gratings, grids, Fresnel zones plates, etc.), as well as structures of different sizes and orientations, to be included on one mask and transferred to the wafer with a single exposure cycle.

Abstract: A control circuit is provided for generating a signal effective for switching the polarity of a driving voltage applied to a matrix display to effect AC driving of the matrix display. The control circuit comprises frequency dividing means (1, 2; 5) which are re-settable by a frame signal effective to initiate line sequential scanning and which are arranged to receive a clock signal effective to control the line sequential scanning. The frequency dividing means divide the frequency of the clock signal to produce a frequent-­polarity-inverting signal. The control circuit further comprises adding means (4) for exclusively logically adding the frequent-polarity-inverting signal to an infrequent-polarity-inverting signal, which undergoes polarity switching according to the timing of the frame signal. The adding means thereby generate an added polarity-inverting signal effective to switch the polarity of the driving voltage.

Abstract: A required visual signal for direct observation is produced from a first source of light (4) in the presence of a second source of light, such as ambient light. Light is transmitted from the first source to a defined surface (10) or defined region distant from the first source (4). A means (10) for modulating light is operated between at least a first mode and a second mode. This operation is synchronised with a varying of the intensity of at least one of the sources of light at or above a given frequency equal to or greater than the critical fusion frequency for the size and luminance of the required visual signal. When the modulating means (10) is in the first mode, this allows the required visual signal to be directly observed on the defined surface or in the defined region. When the modulating means (10) is in the second mode, this allows the effect produced by any light from the second source incident on the defined surface or in the defined region to be reduced.

Abstract: The invention relates to a process and arrangement designed, through braking, to keep constant the speed of a motor-vehicle when travelling on downhill slopes. With the aim of producing simple actuation and deactuation of the constant speedkeeping function, the invention is characterized principally in that the constant speedkeeping function commences upon actuation of a driver-activated brake control (17). In connection with this, the lowest vehicle speed is stored as a target value within the memory of a control unit (1). The actual vehicle speed is then regulated towards the target value through activation of the vehicle brakes (4). Only once an ordinary driver-activated control (19) is activated, is the specified regulation towards the target value suspended.

Abstract: A digital computer includes a main and an auxiliary pipeline processor which are configured to con­currently execute contiguous groups of instructions taken from a single instruction sequence. The in­structions in a sequence may be divided into groups by using either taken-branch instructions or certain instructions which may change the contents of the general purpose registers as group delimiters. Both methods of grouping the instructions use a branch history table to predict the sequence in which the instructions will be executed.

Abstract: A bidirectional optical coupler has a single optical fibre link between two transceivers. Each transceiver includes a holographic optical element (HOE) (14), equivalent to a combination of lenses and a beam splitter; a source of monochromatic radiation (16); and a photodetector responsive to the radiation (18). Within a transceiver in the transmit mode, a divergent beam of radiation from the source is incident upon the HOE, and is diffracted, to form a pattern of interference fringes. Radiation is apparently focussed on the adjacent end of the optical fibre, and is transmitted by the fibre. At the other end of the optical fibre, the transceiver is in the receive mode, and the transmitted radiation is emitted as a divergent beam from the fibre, to be incident upon the HOE. The radiation is diffracted, and forms two angularly separated patterns of interference fringes. Thus, the radiation is apparently focussed upon the photodetector, (and upon the angularly separated, inoperable source).

Abstract: A fluid dispensing apparatus is provided with a controller for modifying a tool speed signal from a robot and to generate a corrected signal to the dispenser nozzle flow controller which compensates for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies. The corrected tool speed signal is generated by computing the ideal flow for the tool speed signaled, comparing the computed flow with actual flow data stored in a memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison. The stored data is acquired by operation in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table. The method of operation corrects non-linear flow phenomena such as the shear-thinning effect.

Abstract: A filter is provided for removing certain noise-induced artifacts from a two-dimensional image of a bore-hole wall, this image being formed by signals from a two-dimensional array 12 of staggered electrodes 30 pulled along the bore-hole wall. The noise artifacts are due to a type of noise which varies as a function of depth of the array 12 but which is substantially the same at all electrodes 30 at any given time. The artifacts appear in the image in the form of a "footprint" of the electrode array, 62 as an unintended result of a depth-adjustment process 60 in which the original frames of samples of the signals at one electrodes 30 of the staggered array 12 all taken essentially at the same time, are later resampled to produce frames of samples each corresponding to the same depth in said bore-hole. The filter 68 makes use of the fact that the configuration of the artifact in the image is known, and that the true signal values do not change much between azimuthally adjacent electrodes 30. The preferred form of the filter 62 produces, and subtracts from each sample, a value of noise n which is a function of the depth of each electrode and which is such as to minimize the minimal discontinuity measure:       
 where M is the measured value of the resampled signals for each (i,j), i is an integer representing electrode depths, j is an integer representing electrode azimuth position an the array, and g(j) is a function expressing the position of each electrode with respect to others on the array along the direction of motion of the array. In the preferred form,       
 where w is an number expressing the width of a mathematical sliding window, where  T ⁻¹ is the inverse of a matrix  T  in a matrix equation expressing the solution of the set of linear simultaneous equations derived by setting equal to zero the partial derivatives with respect to n(k) of the minimal discontinuity measure I, where k = i-g(j), where k₁ and k₂ are the parameters of the matrix  T ⁻¹ and where y is a function of the measured sample values.
