Title: Method for enabling high-speed protection switching from working circuit to protection circuit
Inventor: EIJK P VAN
IPC: H04B10/272
Filed: 2002-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a high-speed protection switching method from a working circuit to a protection circuit. SOLUTION: An optical network comprises an optical splitter, connected with (1) a working optical subscriber unit(OSU) of a working circuit, (2) a protection OSU of a protection circuit, and (3) one or more optical network terminal(ONT), where at least one ONT comprises (i) a working line termination(LT) unit of the working circuit connected with the optical splitter via a working optical fiber, and (ii) a protection LT unit of the protection circuit connected with the optical splitter via a protective optical fiber. Protection switching can thereby be made from a working circuit to a protection circuit at high speed. Arrival time of a corresponding downstream cell is measured by both the working unit and the protective LT unit of the ONT, and information concerning the arrival time is transmitted from the ONT to the protective OSU.  A propagation delay time is generated, based on the transmitted information so that the protective OSU is used for communicating with the ONT, when damages to the working circuit is detected and protection switching is executed.

Title: Method for manufacturing aqueous dispersion of fumed silica
Inventor: FUKUDA KEIJI
IPC: B24B37/00
Filed: 2002-03-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing aqueous dispersion of fumed silica which causes less flocculation of silica particles even when continuously energized than a conventional aqueous based dispersion of the fumed silica.  <P>SOLUTION: The fumed silica is added into a liquid having a pH of about 2 to 11 under a shear force to form intermediate aqueous dispersion having a silica concentration of about 20-60 wt.%. The intermediate aqueous dispersion is added into a basic liquid to give a silica concentration of about 1 to 50 wt.% and a pH of about 8 to 12. In the manufacturing method, the fumed silica diffuses little by little into the basic liquid during addition of the silica dispersion thereby causing the silica concentration in the basic liquid (functioning as a receiving parent material) to gradually rise from zero, and therefore the silica particles in the intermediate aqueous dispersion incorporated are quickly moved to an alkaline region where they are provided with a high zeta potential to be in a stable dispersed state thereby attaining enhanced stability against flocculation of the dispersion.  <P>COPYRIGHT: (C)2003,JPO
