Abstract: Procédé de fabrication de trihydrate d'alumine par décomposition en présence d'amorces d'une liqueur sursaturée (1) d'aluminate de sodium issu d'une chaîne du procédé BAYER caractérisé en ce qu'on applique en début de décomposition (A) une action mécanique intense dans la suspension d'aluminate sursaturée (3). L'action mécanique est effectuée en tête de décomposition, par exemple dans le bac d'amorce (A) ou dans un ou plusieurs circuit(s) mettant en recirculation la suspension d'aluminate sursaturée (3) sur le bac d'amorce.  L'action mécanique est effectuée par broyage, par transmission d'ultrasons de haute puissance, par une turbine cisaillante ou encore avec une pompe centrifuge (P) supplémentaire faisant recirculer à fort débit l'aliquote sur un bac auxiliaire. Lorsqu'un bac auxiliaire est employé, on y mélange avantageusement une liqueur d'aluminate sursaturé en alumine avec la suspension à traiter. Le procédé est également applicable aux chaînes de décomposition de type américain.

Title: Human bmp-7 promoter and method for exploring bone-related substance by using the same
Inventor: SUGIURA TAKEYUKI
IPC: A61K48/00
Filed: 1999-04-22
Abstract: The present invention provides a method for exploring low molecular weight compounds which regulate positively or negatively the expression of human BMP-7 with reference to a reporter activity by using 5' upstream region gene containing the human BMP-7 promoter and an animal cell introduced with the vector that has been connected to an appropriate reporter gene. The low molecular weight compounds and their derivatives obtained by the present method have morphogenetic activity or inhibiting activity for bone and cartilage through the expression of the human BMP-7 and are useful as preventive or therapeutic agents for cartilage and bone diseases. Furthermore, the low molecular weight compounds and their derivatives are useful as therapeutic agents for kidney diseases.

Title: Optical coupler for coupling light between one and a plurality of light ports
Inventor: HANSLER RICHARD L
IPC: G02B6/28
Filed: 2000-12-14
Abstract: An optical coupler for coupling light along an axis between a light port on one side of the coupler and a plurality of light ports on another side of the coupler. The coupler comprises a one-side stage with a light port and a many-side stage with a plurality of arms situated about the axis, each having a light port. A midput region separates the one-side and many-side stages and is situated along the axis where the plurality of arms at least initially starts to split from each other in a direction towards the many-side light ports along the axis. Cross sections of each of the respective initial portions of the arms along the direction are arranged about the same distance from the axis. The cross sectional areas of the arms along the axis are larger at a break point region at which the arms fully separate from each other along the axis than at the many-side light ports. At least a pair of the arms each start to split along the direction in a substantially symmetrical manner about the axis.

Title: Method of manufacturing a positive electrode active material of a secondary battery
Inventor: KAWAKAMI SOICHIRO
IPC: H01M10/00
Filed: 1993-11-26
Abstract: A secondary battery exhibiting a long cycle life and comprising a negative electrode active material made of lithium or zinc is provided, the battery at least having a negative electrode made of lithium or zinc serving as the negative electrode active material, an electrolyte (electrolyte solution), a separator, a positive electrode made of a positive electrode active material, a collecting electrode and a battery case, wherein at least the surface of the negative electrode is covered with a film having a structure which allows ions relating to the battery reactions to pass through.      Since growth of dendrite of lithium or zinc at the time of the charge can be prevented, short circuit between the negative electrode and the positive electrode can be prevented. Therefore, the charge/discharge cycle life can significantly be lengthened. As a result, a lithium secondary battery, a nickel-zinc secondary battery, an air-zinc secondary battery, a bromine-zinc secondary battery and a silver oxide-zinc secondary battery of the long cycle life can be manufactured.
Patent CA-2331916-A1 (CA)
Title: Dc power supply
Inventor: KELLY DAVID
IPC: H02M1/00
Filed: 2001-01-22
Abstract: A power supply circuit uses a simplified design for converting AC to DC and powering a flyback transformer.  The switch of the flyback transformer operates at a high frequency and the time of the transformer is controlled to achieve a high power factor. The flyback transformer is fed a rectified AC signal which has not been smoothed in the traditional manner using a bulk hold-up capacitor and in rush limiting resister. Any filtering to smooth the output current or voltage is carried out on the secondary side. In some cases, no smoothing of the output current or voltage is necessary. The time on of the switch is changed if necessary, slowly, relative to the pulsating input signals powering the primary winding. With a fixed  Ton, or slowly varying Ton, a high input power factor can be achieved.
