Abstract: A photodetector capable of normal incidence detection over a broad range of long wavelength light signals to efficiently convert infrared light into electrical signals. It is capable of converting long wavelength light signals into electrical signals with direct normal incidence sensitivity without the assistance of light coupling devices or schemes. In the apparatus, stored charged carriers are ejected by photons from quantum dots, then flow over the other barrier and quantum dot layers with the help of an electric field produced with a voltage applied to the device, producing a detectable photovoltage and photocurrent. The photodetector has multiple layers of materials including at least one quantum dot layer between and emitter layer and a collector layer, with a barrier layer between the quantum dot layer and the emitter layer, and another barrier layer between the quantum dot layer and the collector.

Patent CA-2279874-A1 (CA)
Inventor: NIKOLAEVICH POZDNYSHEV GENNADY
IPC: C09K8/58
Filed: 1998-12-21
Abstract: The invention is referred to the oil production industry and in particular to oil production compositions based on hydrocarbon and/or oil solutions of surfactants which possess ultra low interface tension on the oil-water boundary that determines their ability to independently form stable oil in water type emulsions and show certain oil washing properties at the time of injection into the reservoir. Proposed composition for oil production contains a small number of ingredients. It is easy to prepare, forms kinetically and aggregately stable "oil in water" micro emulsion, as a result of slow adsorption the surfactant on the rock has a good oil washing property and the process is economical. The content of regulator-solvent in the developed composition of 15-25% of mass allows not only to effectively dissolve the surfactant initially in the regulator but also provide required colloid dispersion (close to molecular) state of asphaltene-resin components in oil which assists the formation of associates from surfactant molecules and polar oil components and slows down surfactant adsorption i.e. allows to wash a larger oil volume from the pore volume of the reservoir. 2 tables.

Filed: 1998-01-16
Abstract: L'invention concerne un procédé de commande dynamique de la longueur d'un message de "R_DATA" sur un canal d'accès aléatoire (25). Initialement, on établit (65) un ensemble de valeurs de seuil pour le trafic de niveaux de charge en tenant compte de l'utilisation d'un canal (25) d'accès aléatoire (RACH). Une longueur particulière de message de "R_DATA" est ensuite associée à chacune de ces valeurs de seuil. Le canal RACH (25) est surveillé (70) pour aligner la charge de trafic (50) sur le RACH (25). Une fois atteinte (80, 95) une des valeurs de seuil établies, la longueur de message de "R_DATA" est réglée à la valeur associée à ce niveau de seuil (85). Les messages de "R_DATA" sont ensuite émis (90) selon la nouvelle longueur.
Patent CA-2282230-A1 (CA)
Title: Hydraulic raising apparatus with automatic regulated speeds
Inventor: HUNG MICHAEL
IPC: F15B7/04
Filed: 1999-09-15
Abstract: A hydraulic raising apparatus with automatic regulated speeds can automatically adapt its raising speeds for various load conditions. It mainly comprises additional hydraulic circuits, check valves and adjustable relief valves arranged between the piston rod side chamber and the rodless side chamber of hydraulic cylinders and pumps. The arrangement enables hydraulic cylinders and pumps to change their working modes in a hydraulic circuit, depending on loaded conditions, from a piston type to a spool type and vice versa. Hence the hydraulic apparatus can adjust its raising speeds in agreement with loads. When the apparatus bears a light load, it will quickly carry the load to position. On the other hand, when the load is heavy the apparatus will move it at a slower speed and thus need just reduced input energy. Therefore, the apparatus according to the invention can enhance efficiency to the greatest extent.

Patent CA-2290598-A1 (CA)
Inventor: BLACK PETER MCLAREN
IPC: A61K/
Filed: 1998-05-22
Abstract: The present invention relates to the ability of the ganglioside, GM3 to inhibit proliferation and induce apoptosis in proliferating CNS cells. The present invention further demonstrates the ability for GM3 to reduce cell numbers in primary cultures of rapidly proliferating human glial tumors and the 9L rat gliosarcoma cell line. In addition, GM3 is shown to have no effect on quiescent cultures of normal human CNS cells. A single injection of GM3 three days after intracranial implantation of tumor cells in a murine xenograft model system resulted in a significant increase in the symptom-free survival period of host animals. Therefore, GM3 is useful as a chemotherapeutic agent for human high grade gliomas.
