Title: Process for forming protective film on coated surface of automobile
Inventor: OBARA HIDEKI
IPC: B05B13/04
Filed: 1997-05-28
Abstract: A strippable paint is poured down onto coated surfaces 1, 2 and 3 of an automobile V within regions to be protected, from a plurality of nozzles 10 disposed in parallel in a widthwise direction of the automobile V above the coated surfaces 1, 2 and 3 of the automobile V, while controlling the number of nozzles which are used to discharge the strippable paint, in accordance with the extent of the regions to be protected. Thereafter, the strippable paint is spread over an entirety of the coated surfaces 1, 2 and 3 in the regions to be protected. Thus, the region covered by each of the nozzles can be relatively reduced to efficiently carry out the pouring-down of the strippable paint and to prevent dusts of a coating material from being scattered to a wide range. In addition, the need for a masking step and/or an inspecting/correcting step can be eliminated to reduce the operating steps and further to alleviate the operational load.

Abstract: Une méthode d'imagerie comportant un circuit intégré muni d'un faisceau ionique focalisé est présentée. Selon cette méthode, l'image du circuit intégré est produite à l'aide d'un faisceau ionique focalisé. L'information relative au circuit est ensuite extraite sans traitement. Dans une autre forme, une méthode et un système permettent d'obtenir l'image d'un circuit intégré entier automatiquement sans retirer le circuit intégré du système d'imagerie et nécessitent l'intervention minimale de l'opérateur. La méthode s'appuie sur l'utilisation d'un faisceau ionique focalisé pour produire une image d'une couche exposée d'un circuit intégré puis graver une portion de la couche exposée sur place. Le processus d'imagerie et de gravure est répété jusqu'à l'obtention de la représentation du circuit intégré entier. Un processeur est utilisé pour assembler toutes les couches et produire une topographie tridimensionnelle du circuit intégré. En raison des relations connues entre les couches, la présentation des données en mosaïque est facilitée et la topographie finale est plus fiable que celle produite par les méthodes informatiques courantes.

Title: Magnetohydrodynamic sterilization apparatus and method
Inventor: GREER SEDLEY J
IPC: A61L2/00
Filed: 1997-09-12
Abstract: The object of the invention to use magnetohydrodynamics (MHD) for the specific purpose of destroying populations of microorganisms in materials conducted through a passageway or a static cell. The MHD cell (16) consists of a fluid containment passageway (48) with electrodes (50, 52) positioned between and 90 degrees out of phase to the poles of a magnet (42). A current is sent transversely through the fluid at a right angle to the moving parts other than the fluid itself. The crossed electric and magnet fields induce ion motions that meet or exceed the ion velocities that exist in boiling water. In a flow-through MHD sterilization system (10), the material flows past a flow transducer (12) and a conductivity material conduit regulates the flow as controlled by the system's ability to sterilize effectively. The system computer (20) also instructs the controlled power supply (28) to provide the correct potential across the MHD cell electrodes (50, 52). A static cell MHD  sterilization system (60) is also described where the passageway through the MHD cell (62) is closed on one end.

Patent CA-2269649-A1 (CA)
Inventor: GROVER WAYNE D
IPC: H04L12/56
Filed: 1999-04-22
Abstract: A method of configuring a node in an IP network by creating a set of router table entries which form a set of virtually preconfigured cyclical routes, or p-cycles, within the IP network. This set of p-cycles is virtual in the sense that the only resources which they normally consume are routing table entries. No transmission capacity is required for them, unless/until they are used to carry packets (traffic.) These p-cycles sit idle and unused until a failure takes place. The routers surrounding the failure then use these p-cycles to route packets, which normally would be lost, around the failure. A router having an entry in its router table identifying the p-cycle, together with an associated port, is also disclosed, and also a data packet that may use a p-cycle to get to its destination.

Title: Fault management during emulation-based antivirus scanning
Inventor: NACHENBERG CAREY S
IPC: G06F1/00
Filed: 1998-02-26
Abstract: A computer-implemented appara-tus and method for countering attempts of polymorphic viruses to evade detection by emulation-based scanners. Such attempts try to exploit differences between the real and virtual execution of instructions. The invention includes a fault manager (158) integrated into the CPU emulator (154) of a virus scanner software product. Be-fore each instruction is emulated by the CPU emulator (154), the fault manager (158) examines the opcode of the instruc-tion to determine (310) whether a "fault" is triggered. If a fault is triggered, the fault manager (158) saves (314) a state record on a fault stack (162), then inter-rupts (316) to a corresponding fault han-dler routine (160). The criteria for trig-gering a fault and the corresponding fault handler routine (160) may be obtained from an updatable data file (164).
