Abstract: Ultraviolet radiation process applies to manu­facture semiconductor devices in order to enhance the thermal stability of developed positive the photoresist film on semiconductor wafers. 
     A method of treating positive photoresist materials applied in order to enhance the thermal stability of the positive photoresist film on semiconductor wafer employing heating and ultraviolet irradiation, which meets the demand for improvement in heat-resistance and plasma-resistance of the photoresists image. The initial heating temperature of the photoresist is set to be a little higher than the initial flow temperature, and the temperature of the de­veloped positive photoresist image is raised in propor­tion as the flow temperature of said photoresist image is increased by exposing the photoresist placed in gas of a lower atmospheric pressure to ultraviolet radiation and / or heating.

Abstract: An improved method of inducing a change in the dynamic torque transmission of an electrorheological fluid in response to an electric field at low current comprising the steps of: (a) selecting a nonconductive liquid phase (e.g. high dielectric hydrocarbon oil); (b) dispersing in the nonconductive liquid phase a particulate phase substantially free of adsorbed water (e.g. zeolite): and (c) subjecting the resulting electrorheological fluid to an electric potential in excess of about one kilovolt at a current density of less than about one-third microamp per square inch. Such a method achieves a rate of increase of dynamic transmission of torque per unit voltage, dM/dV, in excess of about 0.034 ft-lbs x 10⁻³/kV and a ratio of dynamic transmission of torque at an electric field strength of at least 2.4 kV to the dynamic transmission of torque at zero field strength, M/Mo, of at leeast about 2.

Abstract: In a display system having a palette 38 for chrominance and/or luminance information, a display buffer 36 for information defining the pixels of a display field, including index values for indexing the palette to select the chrominance and/or luminance of the pixels, a windowing mechanism 68, 46, 58, 60 is provided for associating a different range of index values with each of a plurality of windows and for responding to index values stored at individual pixel positions in the display buffer 36 to determine the visible extent of a given window within the display field. This allows a plurality of windows to be displayed with a minimum of extra logic and without unduly constraining the choice of colours available within those windows. 
     In the described embodiment, windows are defined in a first phase by storing index values from the range of values associated with that window at all pixel positions for that window. Then, in a second phase, the output of a range comparator 46 for comparing index values stored in the display buffer 36 to the range of values associated with a given window is used to control multiplexer means 60 to cause an item of update information destined for a particular pixel position to be stored at that pixel position in the display buffer 36 only if the comparison is positive.

Abstract: A computationally efficient image contrast enhancement technique is disclosed herein. The image contrast enhancement technique of the present invention is adapted to adjust the intensity of an image of a scene, the image being realized from electrical signals generated in response to radiation received from a plurality of regions within a field of view of the scene. The technique of the present invention includes the step of filling a first matrix with digital entries corresponding to each electrical signal, the difference between the maximum and minimum digital entries defining a first dynamic range. The first matrix is sampled to create a set of digital entries having a second dynamic range substantially similar to the first dynamic range. A histogram of the set of digital entries is then constructed. A first transfer function is generated by at least approximating the integral of the histogram, the first transfer function having a value at each of the digital entries. The technique of the present invention further includes the step of generating a second matrix having entries obtained by multiplying each of the entries of the first matrix by the value of the first transfer function at each of the entries. The image of the scene is generated by driving a display with signals derived from the entries of the second matrix.

Abstract: Undesired signals detected by a main antenna (1) are cancelled by corresponding interference cancelling signals. The output of the main antenna is frequency converted to IF region and decomposed into first and second main baseband components. Decision circuits are provided for making a decision on whether each of the first and second main baseband components exceeds each of multiple thresholds and produces multibit codes as well as error signals. Auxiliary antennas (3-1...3-m) respectively detect the undesired signals and feed auxiliary frequency converters (5-1) for translating the frequency of the respective outputs of the auxiliary antennas to the intermediate frequency. Auxiliary quadrature demodulators (7-1) are provided for respectively decomposing the output of each auxiliary frequency converter into first and second auxiliary baseband components. Correlations (8-1,9-1) are detected between the first auxiliary baseband components and the first error signal and between the second auxiliary baseband component and the second error signal. Amplitude and phase controllers (6-1) are responsive to the detected correlations to control the outputs of the auxiliary frequency converters to generate the interference cancelling signals. Variable length delay lines (4-1) are associated respectively with the auxiliary antennas for introducing delays so that both cancelling signals and corresponding interfering components are time-coincident at the summing circuit.

Abstract: A neural network utilizing the threshold characteristics of a semiconductor device as the various memory elements of the network. Each memory element comprises a complementary pair of MOSFETs in which the threshold voltage is adjusted as a function of the input voltage to the element. The network is able to learn by example using a local learning algorithm. The network includes a series of output amplifiers in which the output is provided by the sum of the outputs of a series of learning elements coupled to the amplifier. The output of each learning element is the difference between the input signal to each learning element and an individual learning threshold at each input. The learning is accomplished by charge trapping in the insulator of each individual input MOSFET pair. The thresholds of each transistor automatically adjust to both the input and output voltages to learn the desired state. After input patterns have been learned by the network, the learning function is set to zero so that the thresholds remain constant and the network will come to an equilibrium state under the influence of a test input pattern thereby providing, as an output, the learned pattern most closely resembling the test input pattern.
