Patent EP-0258560-A2 (EP)
Inventor: LUMELSKY LEON
IPC: G09G5/00
Filed: 1987-06-26
Abstract: A display controller provides multiple different resolutions by selectively enabling different combinations of shift registers (SHRO-SHR7) between the frame buffer and video look-up tables (VLTs). The VLTs are partitioned, with different partitions being programmed identically in accordance with the values of only the number of address bits which will be active from the shift registers at any one time. For example, reading out any of the 512 lines of the frame buffer twice in succession, before incrementing the line counter to access the next line, allows for using one half of the stored bits each time such line is read, to simulate a horizontal resolution having the double number of pixels. Altematively, making two consecutive passes through the buffer and using each time a different half of the stored bits, allows for simulating a vertical resolution comprising the double number of display lines.

Abstract: A semiconductor photodetector is formed of interdigitated, metal-semiconductor-metal electrodes (18) disposed on a surface (30) of semi-insulating semiconductor material (12), gallium arsenide. Radiation such as infra-red or visible light is converted to an electric current flowing between the electrodes (18A, 18B) upon application of a bias voltage (22) between the electrodes. A Schottky barrier at the junction of each electrode surface and the semiconductor surface limits current flow to that produced by photons of sufficient frequency, or energy, to overcome the Schottky barrier. Tunneling of charge carriers of the current under the Schottky barrier, which tunneling results from the entrapment of charge carriers on the semiconductor surface, is inhibited by the production of a doped surface layer (14) upon the foregoing surface (30) between the electrodes (18A, 18B) to repulse the charge carriers and prevent their entrapment at the surface. The doped surface layer (14) is much thinner than an interaction region of the radiation in the semiconductor material (16) and has sufficiently high resistance to permit the photodetector to function efficiently.

Abstract: In an optical instrument, fiber optics are employed to receive light from a linear filament. The fiber optics are arranged into a plurality of light receiving bundle ends distributed around the linear filament and shaped into narrow rectangular slits aligned with the filament. The fibers from each of the receiving ends are equally distributed between two transmitting ends which direct the light through cylindrical lenses to opposite sides of a rotating filter wheel in a paddle wheel configuration. Light beams from the transmitting ends of the fiber optic bundles pass through filters on the filter wheel to additional fiber optic bundles which carry the received light to a probe.

Abstract: A computer method is disclosed for ranking word similarities which is applicable to a variety of dictionary applications such as synonym generation, linguistic analysis, document characterization, etc. The method is based upon transforming an input word string into a key word which is invariant for certain types of errors in the input word, such as the doubling of letters, consonant/vowel transpositions, consonant/consonant transpositions. The specific mapping technique is a morphological mapping which generates keys which will have similarities that can be detected during a subsequent ranking procedure. The mapping is defined such that unique consonants of the input word are listed in their original order followed by the unique vowels for the input words, also in their original order. The keys thus generated will be invariant for consonant/vowel transpositions or doubled letters. The utility of the keys is further improved by arranging the consonants in the keys in alphabetical order followed by arranging the vowels in the keys in alphabetical order. The resultant mapping is insensitive to consonant/consonant transpositions, as well as consonant/vowel transpositions and doubled letters. The method then continues by applying a ranking technique which makes use of a compound measure of similarity for ranking the key words. By first measuring the number of basic operations needed to convert an input-derived key word into a dictionary-derived key word (the higher the number, the less similar are the words) and then secondly measuring the length of identical character segments in each pair of key words being matched (the longer the length, the greater the similarity), there is developed a scoring system for ranking the similarity of an input word to dictionary-derived key words, which ignores misspellings in the input word

Abstract: In a concrete-reinforcing bar (1, 11) provided with composite elements formed by transverse ribs (2, 12), between the tapering terminal ends (4) of the transverse ribs (2, 12) are arranged elevations (5, 14) which are, for example, wart-shaped. These elevations are calculated so that the rib height decreasing at the end (4) of the transverse ribs (2) and the consequently decreasing mass of the transverse ribs (2) are compensated by at least 5%, but preferably more than 10%. These elevations (5, 14) not only improve the bond in the concrete, but also allow a uniform bending of the concrete- reinforcing bar. In a modified embodiment of the invention, the concrete-reinforcing bar (1) possesses, in addition to the transverse ribs (2, 12), rib-like elevations (14) which extend in the longitudinal direction of the bar and which are arranged in longitudinally extending rows. The rib-like elevations (14) extending in the longitudinal direction of the bar are interrupted in its longitudinal direction and terminate at a distance from the transverse ribs (2, 12). <IMAGE>

Abstract: According to a semiconductor device manufacturing method of the invention, a first polycrystalline silicon layer (20) doped with an impurity, a thin oxide film (19), a second polycrystalline silicon layer (22), and a silicon nitride film (23) are sequentially formed, one upon the other. The silicon nitride film (23), the second polycrystal-line silicon layer (22), the thin oxide film (19), and the first polycrystalline silicon layer (20) are then etched, in a self-aligned manner, by means of a photolithography process. A thick oxide film (24) is formed on a side wall portion of the first poly­crystalline silicon layer (20), using the silicon nitride film (23) as a mask, and after the silicon nitride film (23) is removed, a conductive film (25) is formed on the entire surface. Since a film formation process advances without patterning the first polycrys­talline silicon layer (20), the first polycrystalline silicon layer (20) is not damaged by an RIE process and the like. A defect density of the oxide film (20) formed on the first polycrystalline silicon layer (20) can be reduced. Since the thick oxide film (25) is formed on the side wall portion of the first polycrystal­line silicon layer (20), a withstand voltage and reliability of this portion are largely improved.

Abstract: In a monitor circuit, bipolar-to-unipolar (B/U) converters are respectively connected to spare channels to convert bipolar test signals of pseudo-random sequence received therethrough to RZ (return-to-zero) signals and thereafter to NRZ signals. Each B/U converter includes a clock recovery circuit to recover clock pulses from the RZ signal. The original pseudo-random sequence is recovered from successive instants of the NRZ signal of each B/U converter in response to successive clock pulses. Divide-by-M counters are respectively connected to the clock recovery circuits to generate low frequency clock pulses, which drive D flip-flops to convert the bit pattern of each pseudo-random sequence so that the edges of the binary digits in the converted sequence has a sufficient timing margin with respect to a sampling point at which mismatch is detected between the sequences derived from the spare channels. Detected mismatches are counted to indicate the signal quality and usage of the spare channels when the count exceeds a predetermined level during a specified time interval.
