Abstract: Abstract:    A three-dimensional semiconductor device is constructed in which MOS transistors are arranged, not only in the direction of the substrate surface, but also in a direction perpendicular thereto.  At least one layer of insulator film and of single-crystal film are stacked alternately and deposited on a surface of a semiconductor substrate.  An impurity-doped region formed in each semiconductor film is used as a gate, source or drain of a MOS transistor.  The arrangement provides a device that has a higher integration density than heretofore available.

Abstract: L'oxyde de niobium pur à > 99% Nb2O5 est obtenu par un procédé d'extraction liquide-liquide directement sur la pulpe de lixiviation d'un concentré de pyrochlore par une solution d'acides concentrés de HF et de H2SO4. La pulpe sortant du réacteur est refroidie à ? 30.degree.C, puis alimentée à un circuit primaire d'extraction qui se compose de deux colonnes à plateaux pulsants. Dans la première colonne, l'extraction du niobium et du tantale s'effectue lorsque la pulpe alimentée à la partie supérieure de la colonne rencontre à contre-courant la phase organique (MIBK) alimentée à la partie inférieure. Dans la deuxième colonne, la phase organique chargée provenant de la première colonne est mise en contact avec de l'eau déminéralisée pour en extraire le niobium et le tantale. La phase aqueuse contenant le niobium et le tantale est traitée dans un circuit secondaire pour séparer le niobium du tantale et en faire la récupération. La pulpe débarrassée de son contenu en niobium et en tantale sédimente au bas de la première colonne. Elle est pompée de façon continue vers un circuit de récupération de HF et H2SO4 et ensuite à un circuit de traitement des effluents. La phase organique après la réextraction est recirculée à la première colonne.

Title: Movable medium containing binary code
Inventor: LORENZO JOHN L
IPC: H03M7/12
Filed: 1983-08-02
Granted: 1987-04-21
Abstract: Abstract of the Disclosure A quasi binary coded decimal (BCD) form is disclosed along with apparatus for using the same.  The value assigned to a combination of binary bits is dependent on the location of the combination on the medium which is encoded.  Use is made of the direction of motion of the medium to determine the position and hence the decimal value of specific combinations of binary bits.  By interpreting certain combinations of bits in two different ways, an additional binary bit of information can be obtained from a given number of bits increasing the obtainable information from conventional BCD codes.

Abstract: ABSTRACT            For cyclically charging the filling tube of a sausage stuffing and closing machine with ready-for-stuffing tubular casing lengths, a tubular casing material flatly wound upon a supply roll is first withdrawn, opened and, in respectively one section length, drawn upon a support.  Thereupon the drawn-on casing section is divided off the material cord and, along with the support, is placed ahead of the charging tube for conveyance thereto while at the same time, a new casing section is drawn onto another support to repeat these working steps in permanent alternation of the two supports.  The invention resides in that each support after being placed ahead of the charging tube along with the casing section drawn thereonto is pushed in the same direction in which the drawing onto the support was performed beforehand, onto the charging tube up to the stopping means, whereupon the support is advanced in the same direction, pulled out of the retained casing section and, finally, removed laterally.  This will save precious time until a new charging operation starts and enhance the degree of efficiency.            A corresponding apparatus for implementing the method is equally suggested.

Abstract: A B S T R A C T           APPARATUS AND PROCESS FOR THE SEPARATION   OF FLUID CRACKING CATALYST PARTICLES       FROM GASEOUS HYDROCARBONS      Catalyst and hydrocarbon vapours are separated in a cyclone zone attached to the discharge of a riser cracking operation. Vortex stabilizing means separating the cyclone zone from a stripping zone allows stripping gas from said stripping zone to be passed upwardly into said cyclone zone countercurrent to the downward flow of catalyst, thereby improving the separation and stripping of gaseous hydrocarbons from separated catalyst. The combined cyclone-stripping zone reduces catalyst hydrocarbon contact time, thereby improving gasoline yield and olefin content, decreasing gas make, and reducing coke deposits.
