Title: Ion bombardment brazing apparatus and method
Inventor: ZHAO PENGSHENG
IPC: C23C14/46
Filed: 1990-06-11
Abstract: ABSTRACT OF THE DISCLOSURE     An apparatus for ion bombardment brazing.  There is a vacuum vessel having a cathode for supporting a workpiece with a joint to be brazed and an anode.  Filler metal is located near the joint for spreading thereinto as in vacuum brazing.  The process involves exposing the workpiece to ion bombardment when the cathode is in glow discharge.  The workpiece is thereby heated and its surface cleaned.  Further heating results in melting of the filler metal and spreading thereof into the joint.  In addition to combining a cleaning step with the brazing step, it has been found that the process has the advantage of not requiring the relatively low pressures required in vacuum brazing and can provide a shorter work cycle.

Title: Multi-fiber alignment package for tilted facet optoelectronic components
Inventor: BOUDREAU ROBERT A
IPC: G02B6/42
Filed: 1990-08-02
Abstract: MULTI-FIBER ALIGNMENT PACKAGE FOR TILTED FACET OPTOELECTRONIC COMPONENTS            ABSTRACT      A method of compensating for the angular coupling of optical fibers to a tilted facet optoelectronic component involves a precise calculation of the coupling angle with respect to the active layer of the component and with respect to the side walls of the package in which the component is to be mounted.  With these angles computed, the tilted facet component is positioned on a carrier at an offset to the perpendicular such that input/output fibers can exit the component package perpendicularly to its sidewalls.  The component is secured to the carrier by a solder having a high melting point such that subsequent soldering of parts to the carrier will not affect the component positioning.  A localized cooling method then allows the sequential alignment and soldering of one optical fiber at a time to the offset tilted facet component, while previously aligned and soldered optical fibers are held fixed.  This method utilizes the mechanical property of a sharp melting point eutectic alloy solder or a pure metal solder for the fiber connections and is effective for multi-fiber optoelectronic packages demanding stability and high precision.  A package design for tilted facet optoelectronic components requiring multi-fiber alignment incorporates this feature of localized cooling internally. The package utilizing localized cooling method internally eliminates the tilted facet-optical fiber alignment problem, while providing standard lead configurations.

Title: Process for the manufacture of a torsional vibration damper
Inventor: ANDRAE RAINER-HORST
IPC: F16F15/124
Filed: 1990-11-07
Abstract: ABSTRACT         A process for the manufacture of a torsional vibration damper includes transforming an annular deformation region of a metal sheet to an inertia ring through cold forging and affixing the inertia ring to a hub ring by means of an intermediate layer of rubber.  The metal sheet is supported during cold forging in a shape preserving manner at a holding region located radially inwardly of the deformation region. The metal sheet is, in the deformation region, subjected to a radially inwardly directed upsetting action of an upsetting tool in such a way that a folding of the deformation region is substantially prevented. The metal sheet is simultaneously rotated around its axis relative to the upsetting tool.  The process provides for the simplified manufacture of torsional vibration dampers having a higher momentum of inertia and a higher efficiency-weight ratio.  Subsequent cutting, forging or molding is substantially obviated.

The fibers may be fabricated to have a small diameter and are thermally stable at high temperatures.  The process is carried out by initially forming fibers from a preceramic polymeric precursor comprising phenyl-containing polyorganosiloxane resins.  The fibers are then infusibilized to render them nonmelting followed by a pyrolysis step in which the fibers are heated to a temperature in excess of 1600°C. in a nonoxidizing atmosphere to form substantially polycrystalline silicon carbide fibers. The substantially polycrystalline silicon carbide fibers which are formed by the process of the present invention have at least 75% crystallinity and have a density of at least about 2.9 gm/cm3.         The polymeric precursor or the fibers contain, or have incorporated therein, at least about 0.2% by weight boron.  This incorporation of boron may be accomplished either prior to or during formation of the fibers or during at least one of the infusibilizing or pyrolyzing steps of the process.

Abstract: A composite brake drum particularly adapted for motor vehicle applications.  The brake drum includes a reinforcement assembly embedded within the cylindrical portion of the drum.          The reinforcement assembly is preferably made from steel wire stock and includes a plurality of circular loops spaced axially within the brake drum cylindrical portion.  Axially extending locator wires  are mechanically  fastened to  the  reinforcing loops and serve to locate the loops.   End portions on the locator wire contact only one of the mold halves forming the mold  cavity  and  enable  the  device  to  be  essentially self-locating without crossing the parting line of the mold.          By not crossing the parting line, the position of the loops is maintained within acceptable tolerance limits from the finished friction surface of the drum.

Abstract: Abstract of the Invention A constrained character entry form for receiving hand printed characters suitable for machine reading with the form including a web for receiving hand printed characters, and printed on the web a countable number of preprinted constellations of at least three minimum sized visible dots arranged in columns and rows with each of the constellations having a height that is equivalent to the spacing between a column of three equally spaced dots to permit characters to be hand printed using substantially straight lines emanating from and terminating at two or more of said dots.  The invention also includes a method for entering hand written characters into an automated character reading system.  Initially a web is provided for receiving hand printed characters with a countable number of preprinted constellations of at least three minimum sized visible dots arranged in columns and rows with each of the constellations having a height that is equivalent to the spacing between a column of three equally spaced dots to permit characters to be hand printed as lines emanating from and terminating at two or more of said dots.  Then a countable number of characters are hand written on the web wherein each of the characters is drawn as a series of lines which start and terminate at selected ones of the dots.  Next, the web is optically scanned to generate an electrical signal corresponding to markings on the web between each pair of adjacent dots within a constellation. Finally the signals are compared against a set of reference signals corresponding to a set of acceptable characters and a determination is made as to the closest matching character to the written character.
