Title: Single crystal sic and a method of producing the same
Inventor: TANINO KICHIYA
IPC: C30B29/36
Filed: 1998-11-06
Abstract: The single crystal SiC according to the invention is produced in the following manner. Two complexes M in each of which a polycrystalline film 2 of .beta.-SiC (or .alpha.-SiC) is grown on the surface of a single crystal .alpha.-SiC substrate 1 by thermochemical  deposition,  and  the  surface  2a  of  the polycrystalline film 2 is ground so that the smoothness has surface roughness of 200 angstroms RMS or smaller, preferably 100 to 50 angstroms RMS are subjected to a heat treatment under a state where the complexes are closely fixed to each other via their ground surfaces 2a', at a high temperature of 2,000°C or higher and in an atmosphere of a saturated SiC vapor pressure, whereby the polycrystalline films 2 of the complexes M are recrystallized to grow a single crystal which is integrated with the single crystal .alpha.-SiC substrates 1.          Large-size single crystal SiC in which impurities, micropipe defects,  and the like do not remain,  and which has high quality can be produced with high productivity.

Title: Procedes et systemes pour installer un grand nombre de points de test sur des cartes de circuits imprimes
Inventor: GALE ALAN ANDREW
IPC: G11C29/48
Filed: 1997-05-02
Abstract: L'invention a trait à un procédé de fabrication d'une carte de circuits imprimés (PCB) pour PCMCIA (Personal Computer Memory Common Interface Architecture). Le procédé consiste à fabriquer un PCB ayant une zone PCMCIA et une zone auxiliaire. La zone PCMCIA dispose de multiples emplacements aménagés à recevoir des composants électroniques. La zone auxiliaire est configurée pour accueillir de multiples points de test. Le procédé consiste également à équiper la zone PCMCIA de composants électroniques. Des tests sont ensuite effectués dans la zone PCMCIA en établissant un contact électrique avec au moins quelques uns des multiples points de test dans ladite zone auxiliaire. Si les tests ne produisent pas des résultats satisfaisants, des diagnostics sont posés et des réparations effectués. Si les tests produisent des résultats satisfaisants, la zone auxiliaire est séparée de la zone PCMCIA et on obtient une PCB pour PCMCIA équipée et testée.
Patent CA-2254028-A1 (CA)
Title: Hybrid electric vehicle with traction motor drive allocated between battery and auxiliary source depending upon battery charge state
Inventor: GREWE TIMOTHY M
IPC: B60L50/15
Filed: 1998-11-12
Abstract: An electric vehicle is controlled to conform its operation to that of a conventional internal-combustion-engine powered vehicle. In some embodiments, the charging of the batteries by the auxiliary source of electricity and from dynamic braking is ramped in magnitude when the batteries lie in a state of charge between partial charge and full charge, with the magnitude of the charging being related to the relative state of charge of the battery. The deficiency between traction motor demand and the energy available from the auxiliary electrical source is provided from the batteries in an amount which depends upon the state of the batteries, so that the full amount of the deficiency is provided when the batteries are near full charge, and little or no energy is provided by the batteries when they are near a discharged condition. At charge states of the batteries between near-full-charge and near-full-discharge, the batteries supply an amount of energy which depends monotonically upon the charge state. Charging of the batteries from the auxiliary source is reduced during dynamic braking when the batteries are near full charge. Control of the amount of energy returned during dynamic braking may be performed by control of the transducing efficiency of the traction motor operated as a generator.

Patent CA-2256483-A1 (CA)
Title: Lipide kinase p13
Inventor: VANHASEBROECK BART
IPC: A61K48/00
Filed: 1997-05-30
Abstract: L'invention concerne une nouvelle kinase lipidique appartenant à la famille des kinases P13. Les kinases P13 catalysent l'addition de phosphate à l'inositol produisant un monophosphate, un diphosphate et un triphosphate d'inositol. Les phosphates d'inositol ont une incidence dans la régulation de cascades de signalement intracellulaires qui entraîne des modifications d'expression génique, lesquelles, entre autres effets, peuvent causer un remodelage de la cytosquelette et une modification de la motilité cellulaire. Plus particulièerment, l'invention concerne une nouvelle kinase humaine de la famille P13, la kinase p110 delta , qui interagit avec la kinase p85, a une large spécificité phosphoinositidique et est sensible aux mêmes inhibiteurs que la kinase p110 delta  de la famille P13. Toutefois, à la différence des kinases P13. Toutefois, à la différence des kinases P13 précédemment identifiées qui ont un mode d'expression ubiquiste, la kinase p110 delta  s'exprime sélectivement dans les leucocytes. Qui plus est, la kinase p110 delta  révèle une expression étendue dans la plupart des mélanomes attestés, et peut donc jouer un rôle crucial dans la régulation de la faculté métastatique révélée par des mélanomes. L'identification d'agents qui augmentent ou réduisent l'activité de la kinase p110 delta  peut ainsi empêcher la métastase cancéreuse.

Patent CA-2262595-A1 (CA)
Inventor: GRUBER PETER
IPC: A61K9/36
Filed: 1997-08-14
Abstract: An easy to swallow pharmaceutical composition consists of one or several coated particles with a core which contains an active substance and a coat with one or several layers. The coating layer(s) contain at least one hydratable, pharmaceutically acceptable polymer which in contact with saliva or water forms a coherent, mouldable, viscous mass with a slippery surface which does not adhere to the mucous membranes of the mouth and which prevents the active substance-containing particles from leaving the mass and releasing the active substance in the mouth cavity. The coating layer or the outermost coating layer contains an effective amount of at least one salivation promoting agent. The formation of a mouldable, slippery mass and the taste-masking properties of the coating make the composition suitable in particular for administering highly dosed or bad tasting active substances, and can preferably be swallowed even without any liquid.

Patent CA-2273321-A1 (CA)
Inventor: SPRULES RODNEY K
IPC: C10L5/44
Filed: 1999-05-28
Abstract: A solid burnable fuel composition which contains a major proportion of spent dried coffee grounds is described. The fuel composition includes at least 50% dried spent coffee grounds and a combustible wax which are mixed together and compressed into a suitable shape for combustion. The fuel composition may further include a small amount, 10% or less, of a coking agent useful to control burn rate and to prevent cracking of compressed fuel during combustion. Small amounts of cellulosic material may also be incorporated to improve the structural properties of the composition. Due to its superior heat and flame production, dried spent coffee grounds are an excellent fuel source for processed fuel products such as fire-logs and fuel pellets. The advantage is a hotter, cleaner burn which produces less soot and smoke, releases fewer harmful pollutants and provides a brighter flame over a longer period of time.
