Abstract: A connector device and method of use thereof provide positioning and hermetic sealing of electrical contacts in protective housings. The housings protect wires which connect the speed sensor of a turbine engine to a display. The connector supports the electrical contacts in an electrical insulator. The connector includes a malleable flange which is adapted to be hermetically sealed between two housings which protect wires connected to the speed sensor in the turbine engine. The flange is hermetically sealed between a tongue on one housing and a groove in the other housing. The sealing flange extends radially from the central axis of the connector and is compressed by the tongue of a releasable housing into the groove of a permanent housing to form a hermetic seal. The flange supports the electrical insulator which holds electrically conducting inner contacts in position to be slideably mounted into outer contacts which are supported by the connector housing.

Abstract: A measuring probe for a measuring head to detect the oxygen activity of metal melts has a reference substance of known oxygen activity, which upon submersion into the metal melt is separated from the metal melt by means of a refractory solid electrolyte that conducts electrons reliably and conducts primarily oxygen at higher temperatures and which permits the measurement of the electromotive force between the reference substance and a bath contact which makes contact with the metal melt. The surface of the solid electrolyte is subjected to a surface cleaning treatment, primarily by means of etching.

Abstract: A method of fabricating a self-aligned zener diode provides for N.sup.+ and P.sup.+ regions having the large dopant concentrations necessary for compatibility with shallow junction silicon gate CMOS devices. A contact region is provided on the substrate, doped with N-type dopant ions, and etched to cover a portion of the region in which a zener diode is to be formed. A P.sup.+ region is implanted using the doped contact region as a mask. Then, N-type dopant ions are diffused from the contact region to the underlying substrate, thereby providing self-aligned P.sup.+ and N.sup.+ regions having a well defined P-N junction.

Abstract: An integrated capacitor having an oxide layer of less than 500 .ANG. as a dielectric or insulator. A method of fabricating a capacitor including the steps of forming an oxide layer on a substrate, forming through the oxide layer a first capacitor plate in the substrate, and forming a second capacitor plate on the oxide layer. The method also includes the step of restructuring the oxide layer after the step of forming the first capacitor plate. Since the first capacitor plate is formed through the oxide layer the oxide layer can be grown on an undoped or lightly doped substrate; thus, the effects of the doping level on the growth rate of the oxide layer are eliminated and oxide layers having a uniform thickness of less than 500 .ANG. can consistently be provided.

Abstract: What is proposed is an apparatus for a shielded terminal connector that eliminates EMI leakage from coaxial cables in which a resilient bushing of a conductive material is inserted between exposed shield portions of the coaxial cable and the interior surface of a backshell housing, the latter being compressed onto a connector housing for the cable and the resilient bushing itself so that the bushing is gripped tightly by the backshell housing and thus completely fills the space between the exposed shield portions of the cable and the surrounding interior surface of the backshell housing.

Abstract: Certain 2-deoxystreptamine aminoglycoside antibiotics, substituted on the 1-amino group by an alkyl group bearing one or more hydroxy groups, are useful antibacterial agents. The 2-deoxystreptamine aminoglycoside compounds which are substituted in this manner include the kanamycins, the gentamicins, tobramycin, ribostamycin, the neomycins, and 6'-N-alkyl derivatives thereof.

Abstract: An improved wet caustic process of the Bayer method for the extraction of alumina from bauxite containing amounts of both goethite and a monohydrated alumina wherein lime is added only after the bauxite slurry has been heated to a digestion temperature of at least 200.degree.C.
