Title: High-density electronic modules, process and product.
Inventor: GO TIONG C
IPC: H05K7/06
Filed: 1987-10-20
Abstract: A high-density electronic module (24) is disclosed, which is suitable for use as a DRAM, SRAM, ROM, logic unit, arithmetic unit, etc. It is formed by stacking integrated-circuit chips (22), each of which carries integrated circuitry. The chips are glued together, with their leads along one edge, so that all the leads of the stack are exposed on an access plane (28). Where heat extraction augmentation is needed, additional interleaved layers are included in the stacks which have high thermal conductivity, and are electrical insulators. These interleaved layers may carry rerouting electrical conductors. Bonding bumps (31 and 34) are formed at appropriate points on the access plane. A supporting substrate (26), formed of light transparent material, such as silicon, is provided with suitable circuitry and bonding bumps (38 and 42) on its face. A layer of insulation is applied to either the access plane or substrate face, preferably the latter. The bonding bumps on the insulation-carrying surface are formed after the insulation has been applied. The substrate face is placed on the access plane of the stack, their bonding bumps are microscopically aligned, and then bonded together under heat and/or pressure. A layer of thermally conductive (but electrically non-conductive) adhesive material is inserted between the substrate and stack. The substrate and stack combination is then placed and wire bonded in a protective container having leads extending therethrough for external connection.

Abstract: Procédé de commande numérique de la vitesse et du courant d'un servomoteur. On applique des valeurs de correction (23, 27) de sorte que le gain d'intégration (22) et le gain proportionnel de boucle (26) de la boucle de commande de courant augmentent en fonction de la vitesse du servomoteur. Etant donné que la boucle de commande de courant augmente en fonction de la vitesse du servomoteur, il ne se produit aucune oscillation dans la boucle de courant lorsque le servomoteur tourne à basse vitesse ou est à l'arrêt. Il est en outre possible d'empêcher une diminution du couple provoquée par la diminution du gain de boucle de courant pendant le fonctionnement à grande vitesse.

Title: Adjustable surgical staple and method of using.
Inventor: RICHARDS WILLIAM D
IPC: A61B17/064
Filed: 1988-10-31
Abstract: An adjustable surgical staple for use in joining together two pieces of human or animal tissue. The staple has a spine and two legs, with the spine being slotted along its length so as to divide the spine into two separate cross members. Bending the cross members towards or away from one another alters the distance between the leg portions of the staple, thereby allowing precise adjustment of the tension of the joinder between the tissues being joined.

Abstract: For the uniform distribution of the matter to be fluidised (fine raw coal) in the mixing zone of a fluidised bed, a swing chute 4 is provided underneath a cellular wheel lock 2, which chute uniformly applies the cell content of a cellular wheel lock at the time to the surface of the mixing space, whereupon mixing of the fluidised bed takes place. The swing chute 4 is steam-heated and mounted on a swivel bearing 6, the chute sheets being arranged in V-form and extending into the vicinity of the surface of the fluidised bed. To enlarge and smooth out the fluidised bed, it is designed in modular construction. The invention also allows similar operation of the individual fluidised bed modules, so that the design throughput of the overall fluidised bed is optimised. <IMAGE>

Abstract: A semiconductor device is formed of a sandwich of first (12) and second (14) layers of semiconductor material forming a heterojunction therebetween and a two dimensional carrier gas (20) in the second layer (14). First (22) and second (24) spaced electrodes are disposed on the surface of the first layer (12) for inducing first and second potential barriers to the flow of charge carriers in the carrier gas (20). Ohmic contacts (32, 34, 36) are deposited in the base region (26) defined between the electrodes (22, 24) and in the emitter (28) and collector (30) regions defined on opposing sides of the electrodes (22, 24). The width (X₁) of the first electrode (22) is formed narrow enough so that the first potential barrier beneath the electrode permits tunnelling of charge carriers into the base region. The width (X₂) of the second electrode (24) is wide enough so that the second potential barrier prevents tunnelling. Electrons tunnelling through the first barrier are hot and ballistically move through the base region (26) to the collector (30).

Abstract: A process for coating at least one surface of a polyimide sheet with copper in the absence of an adhesive, initially comprises hydrophilizing the surfaces of the polyimide with a caustic solution, then contacting said sheet with a catalyst to create surfaces receptive to electroless deposition of nickel or cobalt. After depositing nickel or cobalt coatings which are electrically conductive, microcracks are formed in said coatings, and said polyimide sheet coated with nickel or cobalt containing microcracks is heated to volatalize components in said polyimide sheet. Subsequently copper is deposited on said nickel surface or cobalt surface by electrolytic deposition to form exposed copper coatings on said polyimide sheet. The layers of the resulting laminate are tenaciously bonded, exceeding current standard bond strength requirements for materials to be used in electronic circuitry.

Title: Novel non-reverting shigella live vaccines.
Inventor: STOCKER BRUCE ARNOLD D
IPC: C07K14/255
Filed: 1989-03-02
Abstract: Live vaccines are provided and methods for preparing the live vaccines for protection of a host from a pathogenic microorganism. The vaccines are prepared by introducing at least one modification in a gene involved in at least one, normally at least two, biosynthetic pathways involving the production of products which are unlikely to be found in the disease susceptible host. The modification results in a gene change which cannot be repaired by a single step, e.g. polynucleotide deletions and inversions. Where the aro gene suffers such a change, the resultant auxotrophic mutants require aromatic amino acids, p-aminobenzoic acid and 2,3-dihydroxybenzoic acid or a highly concentrated source of absorbable iron. The auxotrophic mutations have substantially reduced or nonexistent virulence while retaining the desired immunogenicity to initiate the immunogenic response. Various techniques can be employed for providing the desired change.
