Abstract: An electro-optical system that implements the self-tiling process of finding proper Iterated Function Systems for modeling natural objects. The system can operate in two different modes, a real-time interactive mode and an automated mode. The purpose of the system is to speed up the process of finding a proper IFS for a given object to be modeled. The system makes use of optical processing, including optical means for rotating, magnifying/demagnifying and translating an input image. Optical beamsplitters are used to combine transformed images to produce a tiled output image. In one embodi­ment, an automated controller evaluates the goodness of the match between the tiled image and the input image and generates control signals which cause adjustment of the settings of the optical means. The process is repeated automatically until the match is sufficiently good. The invention can also be operated in a manual, man-in-the­loop mode.

Abstract: A planetary transmission consisting of a gearing to superimpose a number of revolutions, in which the number of revolutions imposed is applied to the internal gear of the planetary transmission with the aid of a control gearing, is intended to allow economical manufacture and take up a small amount of space. For this purpose, the control gearing 2 is designed as a Wolfrom gearing, in which a driven sun gear 9 meshes in at least two planet gears 10 revolving around the sun gear 9 and guided in at least one fixed first internal gear 11, 12, and in which the planet gears 10 simultaneously also engage in a rotatable second internal gear 13 arranged coaxially with the fixed first internal gear 11, 12 and having a lower number of teeth than the first internal gear 11, 12, and in which furthermore the second internal gear 13 drives the internal gear 14 of the main planetary transmission. The planet gears 10 of the control gearing 2 run, in particular, without a carrier, i.e. they are centred solely by the sun pinion 9 and the fixed internal gear 11, 12. The fixed internal gear 11, 12 is divided into two axially spaced parts, which can be integrated into the housing of the main planetary transmission. The rotatable internal gear 13 of the control gearing 2 is arranged axially between the fixed internal gears 11, 12. <IMAGE>

Abstract: This invention relates to an improved process of blow molding, and to improved compositions useful for blow molding, wherein articles are blow molded from compositions formed from thermoplastic polymeric material, a fluorinated olefinic polymer or copolymer and, optionally, an elastomeric impact modifier. The presence of the fluorinated olefinic polymer or copolymer in the blow molding composition increases the melt strength of the thermoplastic polymeric material. This makes the thermoplastic polymeric material more useful for blow molding because a parison of greater size and weight can be formed from the polymeric material because of its increased melt strength.

Abstract: In automatic focusing apparatus of a video camera, any of the entire area, the central area and the midmost area of a picture is selected as an in-focus target area, so that an automatic focusing operation is performed in accordance with a focus evaluating value of the in-focus target area. When the entire area of the picture is selected as the in-focus target area, a focus evaluating value of the central area of the picture is simultaneously evaluated. When the automatic focusing operation starts, the entire area of the picture is selected as the in-focus target area, and if the focus evaluating value of the central area becomes higher than a predetermined value, the in-focus target area is switched to the central area of the picture. When the midmost area of the picture is manually set as the in-focus target area, the midmost area is selected with priority as the in-focus target area.

Abstract: For the underground replacement of damaged sewage pipes of inaccessible diameter and into which house connection pipes lead, a method making it possible to work completely underground is described. In a first working step (a), each house connection pipe (2) is first cut off through one or more radial separating lines from the old sewage pipe (1) by means of a separating device which can travel in the old sewage pipe (1) and be inserted through the mouth opening. Subsequently, in a process step (B), a boring device which breaks open the old sewage pipe (1), followed by pipe sections forming the new sewage pipe are prepressed from a pressure shaft through the old sewage pipe. When the old sewage pipe (1) has been replaced over the intended length by the new sewage pipe, according to a further process step (c) a sealing compound which joins the sewage pipe to the house connection pipes (2) and hardens approximately in the shape of a tube is introduced, by means of a shaping and pouring device which can travel in the sewage pipe, through lateral connection openings. <IMAGE>

Abstract: The present invention permits the testing of the sewing characteristics of various types of sewing threads under conditions which simulate the normal conditions encountered when performing various fabric seaming operations in the conventional manner. The testing of the sewing characteristics of the sewing threads is carried out in an economical manner by using narrow test strip fabric (F1,F2) so that the test results can be ascertained in a short period of time. The method and apparatus of the present invention permits various types of sewing threads to be subjected to the identical and repeatable conditions so that an accurate comparison of the sewing characteristics can be made. The sewing thread test can be carried out on relatively inexpensive narrow test fabric strips (F1,F2) which are fed to and past the stitching needle of the sewing machine (32) in various angular paths of travel relative to the needle and at preselected variable speed rates.

Abstract: A method for applying photoresist to a top surface (22, 24) of a semiconductor wafer (10) for defining an electronic circuit pattern. The wafer is placed on a horizontal turntable and a liquid solvent is dispensed onto the wafer's top surface. Spinning the wafer distributes a film (30) of the solvent to a substantially uniform thickness over the entire top surface. Liquid photoresist is dispensed onto the top surface of the wafer over the solvent film, preferably while the wafer is spinning, to distribute the photoresist in a layer (36) over the entire top surface of the water. Discharge of photoresist is controlled so that the top surface of the wafer remains entirely wetted by the solvent film during distribution of the liquid photoresist. The solvent has a lower viscosity than that of the liquid photoresist and the solvent film thickness is sufficient to enable the photoresist to fully cover any bare silicon, high density or undercut circuit features, generally in a range of 500 to 10,000 Angstroms and preferably 1,000 to 5,000 Angstroms.

Abstract: The surface of a barrier layer (5) interposed between a silicon substrate (1) and aluminum wiring (7) connected thereto is oxidized by heat treatment at 350 to 450°C in an atmosphere having substantially the same composition as that of air or immersion in an oxidising chemical to form an oxide film (6) on the surface, and the wiring layer (7) is then formed thereon. The presence of the oxide film (6) inhibits interdiffusion between the silicon substrate (1) and the aluminum wiring (7) and reaction between the aluminum wiring (7) and the barrier layer (5). Since this oxide film is formed by oxidation at the atmospheric pressure, the oxide film is not excessively oxidised even if it is exposed in air at a relatively high temperature of about 300°C. The oxide film having a thickness and properties which produce the tunnel effect can be formed with good reproducibility.
