Title: Method of fabricating optical nonlinear thin film waveguide and optical nonlinear thin film waveguide
Inventor: IKUSHIMA AKIRA
IPC: G02F1/355
Filed: 1999-02-23
Abstract: A Ge-added SiO2 thin film (12) is formed on a glass substrate (10), and a metal film (14) is formed thereon (S11 to S13). By etching the metal film (14), a pair of electrodes (14a, 14b) mutually opposed at a predetermined interval is formed (S14). An insulating thin film (16) is formed on the insulating film (12) and the electrodes (14a, 14b) (S15). While applying ultraviolet radiation, a high voltage is applied between the electrodes (14a, 14b) to perform ultraviolet excitement polling to impart an optical nonlinearity to a channel region (18) (S16). By controlling the voltage application to the channel region (18) having the optical nonlinearity, the light transmitted through the channel region (18) is controlled. Thus, an optical nonlinear waveguide for propagating single mode light is formed on a glass substrate.
Patent CA-2323567-A1 (CA)
Inventor: BRENNER LAURENCE D
IPC: A61M25/00
Filed: 1999-04-23
Abstract: L'invention concerne un dispositif d'accès vasculaire pour infuser des liquides chez un patient. Le dispositif comprend une gaine introductrice présentant un ou plusieurs orifices latéraux et pouvant être utilisée avec un cathéter mis en place à travers l'enveloppe, avec un dilatateur mis en place à travers la gaine ou être vide. Le dispositif assure un volume considérable de liquide infusé qui est évacué à travers les orifices latéraux. Lesdits orifices permettent l'infusion d'un liquide, tel qu'un médicament, par son administration à des emplacements spécifiques du patient plutôt que l'infusion de la totalité du liquide par l'extrémité distale du tube de la gaine.
Patent CA-2324478-A1 (CA)
Inventor: VAKHARIA VIKRAM N
IPC: C12N7/01
Filed: 1999-03-31
Abstract: On a mis au point un système permettant de générer un virus de nécrose pancréatique infectieux, non pathogène, vivant (IPNV), un virus d'ARN/ds segmenté, double-brin qui utilisent des produits de transcription synthétiques, dérivés de l'ADN clonée. On a élaboré des clones d'ADNc indépendants, pleine longueur, contenant les régions codante et non codante des segments d'ARN A et B respectivement, de l'IPNV. Un segment A a été modifié pour empêcher l'expression de la protéine NS. Les ARN synthétiques des deux segments ont été produits par transcription in vitro de plasmides linéarisés avec l'ARN-polymérase T7. La transfection de cellules CHSE avec des produits de transcription combinés sens positif des deux segments a généré un virus infectieux. La mise au point d'un système permettant de produire un IPNV privé de protéine NS facilite considérablement les études sur la pathogénèse virale et l'élaboration de vaccins atténués vivants pour IPNV.

Patent CA-2338248-A1 (CA)
Title: Process for the treatment of waste water containing ammonia
Inventor: DIJKMAN HENDRIK
IPC: C02F3/34
Filed: 1999-07-13
Abstract: A process is described for the biological treatment of waste water containing ammonia, wherein the waste water is treated with sludge containing nitrifying bacteria in an aerated reactor, applying a sludge retention time in the reactor which favours nitrite-producing bacteria over nitrate-producing bacteria. The process is characterised by applying a hydraulic retention time in a continuously operated reactor, which is shorter than the sludge retention time as a result of part of the sludge being separated from the reactor effluent and being returned to the reactor. The performance of the nitrification is further improved by applying low oxygen and nitrite concentrations.

IPC: F03B13/10
Filed: 2000-05-26
Abstract: An elongated cylinder is fully submerged, in vertical orientation, just below the mean water level of, e.g., and ocean, and of a length, dependent upon surface waves of preselected wavelength, such that the top of the cylinder experiences relatively large pressure variations in response to over passing waves while the bottom of the cylinder experiences an almost steady pressure substantially independent of the over passing waves. The pressure differential over the length of the cylinder is used for causing relative movements between the cylinder and adjoining water, and such relative movements are used for driving a piston of an energy converter. The cylinder can be hollow and in fixed location for causing water movements through the cylinder, or the cylinder can move through the water relative to a fixed transducer. In one version of the movable cylinder, the transducer is fixedly mounted on a fixed in place float disposed within the movable cylinder. In a second version, the transducer is fixedly mounted beneath the movable cylinder on the ocean floor, and the cylinder is coupled to the transducer.
