Abstract: An improved stereolithography system for generating a three-dimensional object by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, using information defining the object which is specially processed to reduce curl, stress, birdnesting and other distortions, the successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process. Reducing stereolithographic distortion through isolation of stress is described.

Abstract: A method of measuring linewidth loss during the formation of microelectronic circuitry, including the formation of a test pattern constituted by a series of spaced bars on a photographic mask which is to be used to form a predetermined pattern on a substrate material. Either of the bars or the gaps between the bars have the same predetermined width. In the former case the gaps, and in the latter case the bars, have widths which differ incremently stepwise from one to the next. The series of bars are such that the ratio of the widths of one adjacent bar/gap pair is unity. The resultant pattern which is formed on the substrate as a complement of the test pattern is then inspected, and the position where the bar/gap width ratio of the resultant pattern is unity is noted. The linewidth can then be calculated loss from a knowledge of the size of the incremental step and the position of the bar/gap width ratio unity point on the resultant pattern.

Abstract: The functions of two virtual operating systems (e.g. S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system. One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated form 1 to 16 megabytes of contiguous storage from the S/88 main storage. Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques. The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space. The S/88 Operating System is the master over all system hardware and I/O devices. The S/88 processors across the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations. The S/88 and S/370 peer processor pairs to execute their respective Operating Systems in a single system environment without significant rewriting of either operating system. Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: An ohmic heater comprises at least two electrodes 1 contained within a vessel 2 such that the electrodes lie along the length of the vessel 2. The vessel 2 has inlet and outlet ports 4 and 12 in the top and bottom through which a fluid to be heated flows, passing through the vessel 2 along the length of the vessel 2. The electrodes 1 are equally spaced about the axis of the vessel 2 and when in use, are connected to a power supply, such that the total voltage at any point in time at the electrodes is near or at zero. Hence, when in use, a current passes perpendicular to the flow of the fluid, but the electric potential on the axis is near to zero, and hence the leakage current from the ohmic heater is substantially reduced.

Abstract: The ability of viruses to undergo recombination within tandemly arranged homologous sequences can be utilized to generate chimeric genes and proteins. Tandemly arranged homologous sequences will rapidly degenerate in a random fashion to yield a single copy comprised of portions of both original sequences. Therefore, a recombinant virus which contains two related but non-identical genes in tandem array yields a population of recombinant viruses which contain a spectrum of hybrid sequences derived from recombination between the original genes. The viruses, therefore, contain hybrid DNA sequences that encode proteins with new epitopes or different combinations of epitopes. Vaccines are derived which may afford protection against a broad spectrum of antigen types.

These methods allow for the production of plants which thus contain a desired gene, but which are free of vector sequences and/or marker sequences used to transform the plant. The method of transforming such plants calls for transforming the plants with a gene of interest by introduction of the gene on a DNA construct comprising a transposon and foreign ancillary nucleic acids; crossing the transformed plant through self-crossing or with another plant to obtain F1 or more removed generation progeny; and utilizing a means for selecting those progeny that carry the gene of interest and are free of the ancillary nucleic acids. Such progeny may be detected biochemically, by Southern hybridization, through the use of polymerase chain reaction procedures and other methods available in the art.
