Abstract: An improved mechanism for the coarse adjustment of a stage especially for a scanning tunneling microscope stage is described. The stage (13) is moved by forces transmitted through rigid wire springs (10, 64, 88) mounted on leaf spring (40, 60, 84) assemblies which transmit the motion from rigidly mounted micrometer adjusting devices (44, 52, 80). The coarse adjustment mechanism of the present invention provides improved performance over coarse adjustment mechanisms presently available for STM applications. The present invention replaces separate sets of leaf springs for X and Y motion with a single set of four wire springs. This simplifies the design and increases the rigidity and stability by reducing the mechanical path length from the solid base to the X-Y-Z stage (13). The screw mechanisms (44, 52, 80) are all directly connected to the rigid base. This is made possible by the additional pairs of wire springs connected from the X and Y screws to the stage. The following advantages are achieved first, since the screw mechanisms do not move with the stage (13), driving mechanisms such as motors and gears can be simply connected; and, second, the rigidity and stability are increased since the stage (13) position is referenced directly to the base through all three screws rather than through intermediate support structures.

Abstract: In a process for forming an asymmetrically structured pair of CMOS field effect transistors having feature refinements matched to the individual idiosyncrasies of p-channel and n-channel transistors, complementary transistors (14,16) are formed using a single photolithographic mask (13) and a fabrication sequence which begins with p-channel transistor source/drain (17) formation. Thereafter, the p-­channel transistor source/drain regions are metalized (19), n-channel transistor lightly doped drain regions are formed, and sidewall dielectric (27) spaced n-­channel transistor source/drain regions are formed using the p-channel metalization as a mask. The p-­channel transistor source/drain metalization (19) suppresses the effects of the relatively greater p-type source/drain resistivity, while the LDD structure of the n-channel transistor reduces performance degradation attributable to hot electron trapping. The structural asymmetry attributable to the process materially offsets performance limitations common to the individual CMOS transistor types.

Abstract: A network is arranged to generate circuits between source node (N S ) and destination nodes (N D ) by means of datagrams which are guided at each node over a path (D) which minimises delay in establishing the circuit. Certain sub-destination nodes (N B  and N C ) are designated as intermediate circuit nodes by the datagram and accordingly a circuit (C) is established. Each circuit node is determined by the preceding circuit node in such a manner as to minimise the hop count to the destination node (N D ). To this end, each node incorporates in its memory (M) a first list (LIST 1) showing the link with the best hop count to each possible destination node and also incorporates a list (LIST 2) of its links with the best transmission delay to the destination node. These lists are updated dynamically by means of routing information packets which are exchanged between neighbouring nodes. However, best hop count and best delay information is not transmitted over those links (L) which are themselves the subject of that information. In this manner "ping-pong" type looping is avoided.

Abstract: An EMI/RFI shielded door assembly for use in controlling the movement of EMI/RFI in a shielded room or enclosure. The assembly has an electrically conductive frame (3) defining a generally rectangular opening. A conductive door stop (12) is formed on the inner surfaces of the top and side members of the frame (3) to form a pocket into which a shielded door (2) may be held when in its closed position. The threshold of the frame is preferably flat. A series of cam or drop hinges (4) are used to mount the door (2) to the frame (3). The hinges (4) cause the door (2) to be raised or lowered to or from the threshold as it is rotated on the hinges from a closed to an open position and vice versa. A low closure force gasket (15),  e.g. , less than 5 pounds per linear inch preferably formed of a conductive elastomer, is used to fill any gap that may exist between the door and the frame. Optionally, a rotatable EMI/RFI shielding means mounted in a hollow of the bottom of the door and comprised of a flap or flipper like blade attached to a rotatable rod can be used to seal the gap between the door and the threshold.

Abstract: Pour effectuer une reconstruction à trois dimensions d'un objet acquis par une série de projections coniques sur un multidétecteur à deux dimensions, on estime l'objet par une fonction échantillonnée. On projette la fonction échantillonnée et on compare les projections de cette fonction échantillonnée aux mesures résultant de l'acquisition sur le multidétecteur 2D. On en déduit une nouvelle estimation de l'objet et on réitère ces opérations jusqu'à ce que la comparaison soit satisfaisante. Pour projeter, on décompose l'objet tridimensionnel échantillonné sur un espace de fonctions de base gaussiennes. On calcule pour chaque élément d'image des images de projection, la contribution des fonctions de base ces contributions étant égale à l'intégrale du produit des fonctions de base par un support d'illumination de cet élément d'image. On montre que le choix d'une fonction gaussienne comme fonction représentative du support permet d'une part de supprimer les artefacts de la reconstruction, et d'autre part, par la simplification des calculs de reconstruction que ce choix entraîne, d'augmenter la vitesse de calcul de cette reconstruction.
