    摘要： IN MAKING A DIODE ARRAY TARGET FOR A TELEVISION CAMERA TUBE FROM A SILICON SUBSTRATE, THE FACE OF THE SUBSTRATE IS FLOODED WITH A PHOTORESIST MASKING MATERIAL AND THE SUBSTRATE S THEN SPUN TO FORM A UNIFORM COATING OF THE MATERIAL ON THE FACE. DUE TO THE OVERFLOWING, BREAKING DOWN AND SCATTERING OF THE MATERIAL ON THE SUBSTRATE AND DUE TO LEAKAGE FROM A VACUUM SPINDLE HOLDING THE SUBSTRATE, THE MATERIAL OFTEN CREEPS OVER, OR SPLASHES ON, THE BACKSIDE OF THE SUBSTRATE OPPOSITE THE FACE. THIS RESULTS IN A DECREASE IN THE UNIFORMITY OF THE DIODE ARRAY AND REQUIRES AN ADDITIONAL PROCESSING STEP TO MAKE THE TARGET. TO PREVENT THE MATERIAL FROM CREEPING OVER, OR SPLASHING ON, THE BACKSIDE AND THEREBY REDUCE THE PROCESSING STEPS AND INCREASE THE UNIFORMITY OF THE DIODE ARRAY, A FLUID IS FORCED OUTWARD IN AN ANNULAR PATTERN FROM THE CENTER OF THE SUBSTRATE AND AGAINST THE BACKSIDE AS IT IS SPUN. AN APPARATUS FOR EFFECTING THIS FLOW INCLUDES AN ANNULAR NOZZLE POSITIONED BENEATH THE SUB-

    STRATE AND FORMED BY AN UPPER BEVELED FLANGE AND A COACTING CHAMFERED PORTION OF A PAIR OF TUBULAR MEMBERS.

    摘要： An apparatus is provided for painting or otherwise treating solid articles or parts with a liquid and subsequently removing excess liquid, comprising a container for the articles or parts, a tank for containing the liquid, means for dipping the container and articles to immerse the articles in the liquid, and means for retracting the container from the liquid and spinning the container to remove excess liquid and drying while the container and articles are within the confines of the tank. All functions are accomplished by air-operated or other fluid means and controlled by valves actuated by an air-operated fluidic circuit, and in the complete absence of any electrical circuits, thereby avoiding any danger of explosion by ignition of the liquid which might be caused by an electrical spark.

    摘要： Apparatus for directing a moving web, such as metallic foil, about two 90* turns, including means for simultaneously preventing wrinkles in the web, controlling web tension, and accurately guiding the web. The means for performing these functions are mounted on a pivotable support, which pivots in response to edge guide control means to maintain the desired tracking of the web without creating distortion therein.
