Abstract: Abstract Disclosed is the fabrication and structure of very small integrated circuit devices of both PNP and NPN types with very high speeds and low power re-quirements.  The structure provides vertical NPN and lateral PNP transistors formed within the same semi-conductor chip.  The base width of the lateral PNP transistor is very narrow (approximately 300 to 400 nanometers).  This narrow dimension is in part ob-tained by using a well defined chemically vapor deposited (CVD) oxide mask instead of conventional lithographic masking.  To eliminate the emitter current injecting into the substrate the P+ emitter and P+ collector of the PNP transistor are bounded by a silicon nitride and silicon dioxide dielectric layer.

Abstract: STACKER CRANE FOR MOVEMENT OF COILS     Abstract Means for lifting and transporting a load such as a heavy metal coil.  Overhead winch means lifts and lowers a load carriage and the load attached thereto, and a powered wheeled trolley moves the load horizontally above a floor.          Attached to the carriage is clamping means, which engages the coil through its center aperture and its periphery.  The clamping means has two jaws, one movable with respect to the other, the movable jaw also having thereon a movable gripping surface that moves on an inclined surface of the movable jaw towards the fixed jaw to ensure a tight wedging engagement of the load.  The jaws and gripping surfaces provide a non-powered, mechanically firm grip on the load once it has been engaged by the jaws.  The coil may be lifted with the jaws when its center aperture is vertically or horizontally dis-posed, and the load may be placed for storage in either position as well.

The leading and trailing edge portions of the airfoil are cast with cubic unit cells having an [001] direction extending substantially parallel to the longitudinal axis of the article in order to promote thermal fatigue resistance.  The central portion of the airfoil has unit cells with a [111] orientation with respect to the longitudinal axis in order to improve the creep strength and Young's modulus of the airfoil.  The leading and trailing edge portions and central portion of the airfoil may be cast with elongated crystals or may be cast with each of the portions formed as a single crystal.  To cast the airfoil containing metal article, a starter element having portions with unit cells oriented in different directions is placed in an open end portion of a mold with the starter element exposed to both a mold cavity and a chill.  Molten metal is poured against the starter element and crystals are nucleated with unit cells having orientations corresponding to the orientations of the unit cells in the portion of the starter element engaged by the molten metal.  The molten metal which is solidified to form the leading and trailing edge portions of an airfoil engages a portion of the starter element in which the unit cell s have [001] orientations with respect to the longitudinal axis of the airfoil.  The molten metal which is solidified to form the central portion or the airfoil engages a portion of the starter element which has unit cells oriented in a [111] direction with respect to the longitudinal axis of the airfoil.

Abstract: ABSTRACT     Food products are processed prior to consumption in a press form having multiple, separate, pre-selected planar food product molds, each having tapered walls, providing easy food product removal.  The food products can have pastry dough ex-teriors and can be filled with selected food fillings held in position and shaped by dough crust exteriors.  Multiple press form food product molds have regular planar shapes disposed multiple in a tray.  One face of each product mold has a cutting-edge knife disposed thereon, conforming to the mold interior shape.          The cutting-edge knife can be disposed at either mold wall taper terminus.  A cooperatively/shaped, one-piece negative pusher plug mold, sized to intercept each one of the multiple food product molds disposed in the tray, is used to cooperatively push each food product out of the molds in the tray simultaneously.          Additional, easily insertable and removable partitions of single and double cross-wise edge-knife units can be disposed in the molds, further dividing the food products.
