IPC: G03F7/26

Abstract: The contrast of a photoresist layer (18) used in a lithographic process for a given light (17) source is optimized by determining the nonlinear relationship of the photoresist (18) contrast with regard to the thickness thereof and then placing over a substrate (20) a thickness of photoresist (18) corresponding to a desired value of contrast indicated by the nonlinear relationship (14) of contrast (14) with photoresist thickness. The nonlinear contrast (14) with regard to photoresist (18) thickness function is a damped, sinusoidal like function (14) with the difference between maxima (15) and minima (16) contrast values decreasing as the photoresist thickness increases and with higher absolute maxima (15) values for contrast as photoresist (18) thickness decreases. The amount of light (17) needed to fully expose a given thickness of photoresist (18) also varies with the photoresist (18) thickness in a sinusoidal like manner (24) and a phase difference may exist therebetween and the sinusoidal like contrast versus photoresist thickness function (14).

Abstract: In a data storage device (eg: disk drive ) providing amplitude sampling data detection, the amplitude of an analog read back signal is sampled at data clock intervals. The resulting analog values are converted to digital equivalent values. The digital equivalent values are each compared to an expected digital values that is representative of the data that was originally recorded on the disk, to thereby generate a difference value. The resulting collection of difference values are magnitude segregated, and then stored in a plurality of registers, for later use in providing a histogram that is a measure of the disk drive's read error rate.

Abstract: An iterative method of sequencing jobs in a flexible manufacturing environment where such manufacturing jobs have sequence-dependent set-up times provides for solutions which approximate optimal sequencing while requiring only modest computational resources. Initially, the invention recasts a sequence of manufacturing jobs as a dynamic traveling salesman problem (TSP), in which the system must reconfigure itself and then execute each job in the same way a salesman must visit a sequence of cities, but where the distances between cities change depending upon cities already visited. The first step of the invention reduces the difficult dynamic traveling salesman problem to a static TSP, where distances between each possible job pair are fixed as a monotonic function of parts the two jobs share in common. The second step solves the resulting static traveling salesman problem, by maximizing total distance found by exploiting part commonality between jobs, to obtain a good initial solution to the job sequencing problem. The invention further improves upon the initial solution by selectively perturbing the initial sequence and calculating any changes in the number of part swaps required to reconfigure the manufacturing system. The perturbation and calculations iterate until no improvement is found. The ending sequence should be close to optimal for the job sequence and system. As a final step, a modified "keep part needed soonest" algorithm, accounting for later sequence and overall historical use of parts, optimizes the number of configuration changes for the final sequence. To assure near-optimality for the final sequence, a lower bound calculation provides a limit on how few part changes are possible for the current collection of jobs. The inventive method readily handles job sequencing problems which are difficult or impossible to solve with conventional techniques.

Abstract: The device makes possible easy, quick and completely safe climbimg of all types of vertical supports such as trees, wooden telegraph poles or concrete poles (energy transport), masts, lamp posts and the like. It consists of two identical articulated platforms. Each of the platforms is characterised by: - the assembly of two frames of oval shape, which are closed and hollow. Inside the frame, an elastic cable pulls on a rack, the latter can be locked in working position by a bolt which pivots about a fixed point and locks the system. On the other side of the rack, the belting devices of the support, top and bottom, of each of the platforms are attached. The device makes it possible to be completely independent of the shape of the support and of its variations in diameter in the course of climbing, or in the course of descending, while offering a working platform which remains perfectly horizontal.   The device, which is collapsible, robust and light, is well suited to all trades which have to work in complete safety above the ground, in particular telecommunications and energy transport representatives, pruners and hunters. <IMAGE>
