Abstract: ABSTRACT       There is provided an electrically controlled information display device having a two-dimensional planar array of display elements in horizontal and vertical rows.  Each such element can be set to a first station which it displays a light emissive area and a light reflective area, and a second state in which these areas are replaced by a corresponding area of low reflectance. The display may thus be viewed either by transmitted or by reflect-ed light.  The light emissive area of each element is a light trans-missive area in an otherwise opaque member, and each display element includes a vane with a highly reflective face constituting the reflective area, and another face of low reflectance. The vane can be pivoted about a hinge axis adjacent to the light transmissive area between a first position in which the vane covers the light transmissive area exposing its low reflectance area to an observer, and a second position in which the vane uncovers the light trans-missive area and exposed its highly reflective face to the observer. me vane is movable by magnet means between its two positions.

Title: Lanyard release/umbilical electrical  connector
Inventor: CARTER DAVID P E
IPC: H01R13/639
Filed: 1980-07-08
Granted: 1982-08-31
Abstract: ABSTRACT OF THE DISCLOSURE         An electrical connector reconstructed in part to permit lanyard quick release in umbilical usage includes a collet and a detent shell.  The collet has a base, a sort of undulating side extending from the base to a flange-lip extending radially inward at the top of the side (when seated on the base), the flange-lip having keyways corresponding to keys on the barrel of the recep-tacle.  The collet is divided into a number of separate arc lengths, desirably at least three.  The coupling ring has pro-visions for attaching a lanyard.  Also an internal sloping end por-tion which can ride over the collet base but not the collet side.          A detent shell fits partially inside the opening in the coupling ring.  This detent shell has keys corresponding to those on the coupling nut and a nose which can slide underneath the collet base and side.  The ring coupling and detent shell are resiliently held together so that a lanyard can pull the coupling ring back over the detent shell.  The collet arc lengths provide rocker action under the cooperative force of the coupling ring internal sloped end and the detent shell nose.  The rocker motion causes the flange-lip diameter to decrease, after the flange-lip is beyond the barrel keys, and frictionally lock the flange-lip and keys, placing the connector in locked/mated condition.  Pull of the lanyard force-fully moves the coupling ring toward the detent shell.  The inter-nal sloped end and conical nose cooperate to open the diameter of the flange-lip; the collet slips over the receptacle keys and the receptacle section and plug section are unlocked.  Continued axial backward movement unmates the two sections, providing the desired quick release, that is, unlock/unmate, action.

Abstract: SILICON ON SAPPHIRE LASER PROCESS                     ABSTRACT A beam of radiant energy such as a laser beam is applied to an epitaxial silicon island on a silicon on sapphire device before formation of overlying layers of oxide and metal.  The energy beam changes the crystal structure of the epitaxial silicon island to increase the mobility of carriers in the silicon island, improving the speed of transistors formed on the silicon island. The energy beam also causes the material in the silicon island edge to reflow, causing a reduction in the slope of the edge face of the silicon island edge, and a smoothing of the surface of the face, resulting in improved aluminum step coverage and elimination of a V-shaped groove in the first insulation layer at the bottom corner edge of the island, thereby increasing processing yield.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of preparing clad steel products is disclosed, which comprises freely fitting a pipe or bar or a pipe and bar into a pipe, cold-drawing the fitted assembly to obtain an intermediate material in which the pipe and bar of the fitted assembly adhere closely to each other, heating the intermediate material and subjecting the heated intermediate material -to hot working for forming the intermediate material into a desired clad steel product such as a clad steel pipe, a clad steel bar or the like.  The confronting faces of the pipe and bar are cleaned prior to the fitting operation, and a metal plating layer or metal foil coating layer is formed on the peripheral face of the pipe or bar located inside for preventing carburization.  The intermediate material obtained by cold drawing is a clad billet or clad bloom.  When a clad bloom is obtained by cold drawing, it is heated and subjected to slabbing to form a clad billet and the formed clad billet is fed to the step of forming a pipe or a linear steel product such as a die steel.  The bonded area of the pipe and the like on the end face of the clad bloom or clad billet may be sealed by welding prior to the heating operation so as to prevent occurrence of oxidation in the interior.
