Patent CA-2054118-A1 (CA)
Inventor: SHALLENBERGER FRED T
IPC: B23B51/04
Filed: 1991-10-24
Abstract: A metal cutting drill with two replaceable cutting inserts which are positioned to cut the full circumference of a hole during each one-half revolution of the drill. Each insert is triangular and includes an active cutting edge having a curved corner to enable the insert to cut near the center of the hole. Each insert may be inverted and indexed in order to bring an alternately usable cutting edge into active cutting position. By virtue of the inserts being triangular, the curved corners on the cutting edges of the two inserts may be positioned relatively close together and yet sufficient space is left between the inserts to enable the drill body to be relatively thick and strong.

Title: Endovascular Electrolytically Detachable Guidewire Tip
Inventor: GUGLIELMI GUIDO
IPC: A61B18/00
Filed: 1991-01-03
Abstract: An artery, vein, aneurysm, vascular malformation or arterial fistula is occluded through endovascular electrothrombosis by the endovascular insertion of a platinum guidewire tip (30) into the vascular cavity followed by application of a positive current. The guidewire tip (30) is then separated from the guidewire by electrolytic separation of the tip from the guidewire (10). A portion (26) of the guidewire (10) connected between the tip (30) and the body of the guidewire (10) is comprised of stainless steed and exposed to the bloodstream so that upon continued application of a positive current to the exposed portion, the exposed portion is corroded away at least at one location and the tip (30) is separated from the body of guidewire (10). The guidewire (10) and the microcatheter are thereafter removed leaving the guidewire tip (30) embedded in the thrombus formed within the vascular cavity.

Title: Method of making iron foil by electrodeposition
Inventor: VAN HAASTRECHT GIJSBERTUS C
IPC: C25D1/04
Filed: 1992-02-12
Abstract: ABSTRACT OF THE DISCLOSURE       METHOD OF MAKING IRON FOIL BY ELECTRODEPOSITION          Iron foil is made by deposition of iron in an electrochemical cell having an insoluble anode from an acid electrolyte onto a moving cathode by the reaction:        Fe2+ + 2e- - Fe (foil)        (I), and removing the iron foil so made from the cathode.          In a regenerator iron is dissolved into the electrolyte.  To avoid reduction of the foil by Fe3+ in the electrolyte, hydrogen in the form of hydrogen gas or a gas containing hydrogen is supplied to the anode, the anode being such that the anode reaction:             H2 ? 2H+  + 2e-                 (II) takes place, said reaction (II) predominating at the anode over the reaction: 2Fe2+ ? 2Fe3+  + 2e-            (IV). The dissolution of iron in the regenerator takes place at least partly by the reaction:       Fe + 2H+ ?  Fe2+ + H2      (III).

Les comparateurs d'adresses disposent chacun, à titre d'entrée, d'adresses correspondantes de mise à jour et d'accès de fichier de registres A et B. Les comparateurs d'adresses comparent leurs adresses de mise à jour et d'accès de fichier de registres associées, afin de déterminer si le registre du fichier de registres sélectionné pour être sollicité, est égal au registre du fichier de registres sélectionné pour être mis à jour. Si ces deux adresses s'avèrent égales, il est indiqué que le résultat d'une opération de l'UAL, pendant un cycle N d'instructions, est utilisée comme opérande pour une opération d'UAL pendant un cycle N+1. Lorsque cet état est détecté, la sortie du comparateur d'adresses associé permet à l'entrée de sélection correspondante du multiplexeur de transmettre le résultat de l'UAL directement à l'entrée correspondante de l'UAL, contournant ainsi effectivement le fichier de registres.

Title: Direct thermocompression bonding for thin electronic power chips
Inventor: NEUGEBAUER CONSTANTINE A
IPC: H01L21/603
Filed: 1991-10-24
Abstract: Annealed copper foil (12) is coated with chromium film (16), followed by coating with an appropriate thickness of gold film (14) and is thermocompression bonded to an aluminum metallized substrate (18) on a silicon chip (30) to provide solderable, high current contacts to the chip. The foil is formed into appropriate electrical network-contact patterns (40) and is bonded to the silicon chip only where aluminum metallization exists on the chip. Leaf (wing) portions (46) of the foil extend beyond the bound-aries of the silicon chip for subsequent retroflexing over the foil to provide electrical contact at predesignated locations (49). Ex-ternal contacts to the foil are made by penetrating through a ceramic lid positioned directly above the foil area. Thus, direct ther-mocompression bonding of a principally copper foil to aluminum semiconductor pads can replace current gold detent/pump connections by securing a copper conductor to a silicon chip through an intermetallic AuAl2 link and an aluminum stratum.
