Abstract: A kind of burst address sequence generator (10) is to generate 2 n  pulse trains (n is an integer greater than 1) compatible with INTEL 80486 CPU, including the following: One n-bit binary up counter (11), whose input terminal inputs a signal of one first pulse train address (ZERO#) for initializing and to begin counting, and an increment signal (INC) used to trigger the input. The output terminal has n count signal C(0, ..., n-1) to couple to n corresponding XOR gates (12); one transparent latch (13), whose input terminal inputs n address bit A(m, ..., m+n-1) signals (in other words, 2 n  pulse train burst cycles with size of each transmission data at 2 m  bytes; A₀ ∼ A (M-1)  as the continuous lowest address of this 2 m  bytes); one of the input signals and one latched act signal (ALE), the output is the n latched address signals LA(m, ..., m+n-1), as well as n corresponding XOR gates coupled with the n count signals C(0, ..., n-1) and n latched address signals LA in order to obtain n pulse train address signals SA(m, ..., m+n-1). SA can be directly coupled to a static random access memory (SRAM). This invention also concerns a pulse train burst address sequence generator (20), with a delay reduction function to reduce the delay time of address generation by the above-mentioned pulse train burst address sequence generation.

Abstract: An improvement to the ligase chain reaction (LCR) method of selectively and geometrically ligating nucleic acid probes; before the LCR, a template-dependent controlled reaction increases the population of templates capable of supporting template-dependent ligation in LCR selectively in the presence of target nucleic acid, while substantially avoiding creation of any molecules capable of supporting template-dependent ligation in the absence of target nucleic acid. One way to control the initial reaction is to weight the reaction to create templates corresponding to only one of the two target strands, using e.g. template dependent ligation or polymerization. Another way to control the initial amplification is to create templates corresponding to both strands, but to prevent spurious creation of ligation templates by using a probe concentration low enough to avoid blunt end ligation or by using a method of amplification such as PCR that does not generate spurious ligation templates.

Abstract: The rail welding machine, in particular for the butt welding of railway rails (7a), has electrodes (11a, 11b) which are to be placed over a large area against the rails (7a) and are mounted in an articulated manner on their support (41a, 41b). The construction unit movable for feeding one of the rails (7a) is mounted in a pendulum manner in the feed direction. On account of their mobility, the electrodes (11a, 11b) can be snugly placed without problem over a large area onto the surface of the workpiece to be welded, here the railway rails (7a). This results in an approximately uniform current flow over the contact surface, as a result of which overheated contact points can be avoided. On account of the friction-free mounting, i.e. the pendulous suspension of the construction unit in the welding feed direction, an extremely accurate feed of one rail end and a feed force which can be proportioned exactly are possible during the welding operation. An excellent quality of butt weld can be achieved by the accurate control of the welding current, the feed force and the feed travel. <IMAGE>

Abstract: 5 n7 An automatic chemical analysis is performed, in which a sample to be analyzed is reacted with a reagent to measure a concentration of a specific composition in a mixed reaction solution. An information necessary for an initial operation for a measurement of the concentation is first set, the initial operation for preparation of a measurement process before starting of the measurement is executed in accordance with the set information, an elapsing time required for the measurement process is measured and set, the elapsing time is discriminated as to whether or not the elapsing time is within a preset time, and a content of the initial operation is controlled to be changed in response to a result of the discrimination. The discrimination is carried out in accordance with a present time (Tn), an operation termination time (Te) of each of units constituting the analysis sytem and an operation elapsing time (Ts) preliminarily set to each of the units. When the time (Te - Tn) > the time (Ts), a minimumly necessary initial operation is performed, and when the time (Te - Tn) < the time (Ts), an additional operation in addition to the minimumly necessary initial operation is performed.

Abstract: The present invention relates to a method for butt-welding two ends of tubes (pipes) (1, 2) by the arc-melting, under inert gas, of a filler metal between the end faces of these tubes (pipes), with the aid of a non-consumable electrode, characterised in that facing shoulders (3, 5; 4, 6) are hollowed out beforehand on the end faces of the tubes (pipes) and in that a calibrated ring (7) of longitudinal thickness slightly less than the distance separating the faces of the shoulders perpendicular to the common axis of the tubes (pipes) and of radial width substantially greater than the depth of the shoulders, forming the filler metal, is arranged in the groove formed by these shoulders. Such a method is simpler and quicker to carry out and leads to a weld which is more uniform and of excellent quality, with very small misalignment of the butt-welded tubes (pipes). <IMAGE>

Abstract: A method is provided for distinguishing nonconvex polygons from complex polygons in a computer graphics system. The present invention compares the edges of a polygon for self intersection points. Initially, "base" and "compare" edges are designated and bounding boxes for each of these edges are determined. The bounding boxes are then compared and if they intersect the edges may have points in common, whereas if no intersection occurs, then there are no common points and the edges are incremented and a comparison of other edges occurs. If it is determined that bounding boxes intersect, the intersection point for the edges under consideration is determined. If this intersection point lies within both bounding boxes, then the polygon is complex and the test ends. However, if the intersection point is outside either bounding box, then the edges are incremented and processing continues until all relevant edges have been considered.

Abstract: The present invention is directed to a carrier level balancing circuit in which a color aliasing signal occurred when a cameraman takes a picture of an object of an achromatic (black and white) color can be canceled completely. In a carrier level balancing circuit for a color camera formed of a CCD solid state image pickup device (9) of an all pixel separately read out system, two-channel color signals (Gr/Ye, Cy/Gb) output from the CCD solid state image pickup device (9) are multiplied with independent balance coefficients (a/b, c/d) at every line by multipliers (15), (16) while the balance coefficients (a/b, c/d) are switched in a dot-sequential fashion. Also, values of these balance coefficients (a/b, c/d) are set by a coefficient setting circuit (17) in response to a color temperature information. Thus, the carrier levels can be balanced at all sorts of color temperatures.
