  • Publication number: 20050025118
    Abstract: A method and apparatus for improved inter-domain routing convergence, include transmitting reason information associated with a route update or withdraw. An apparatus receiving the reason information associated with the update or withdraw uses the reason information to determine which of its candidate routes are also affected by substantially the same event that triggered the initial route update or withdraw and which of its candidate routes are not affected. For example, a candidate route may be considered to be transient if the apparatus receiving the reason information determines from the received reason information that a candidate route is going to be updated or withdrawn in the near future due. A candidate route considered as a transient route is avoided being advertised as a preferred route.

  • Patent number: 6546530
    Abstract: A method and circuitry for linearly delaying a signal with linear delay steps. In one embodiment, circuitry in an integrated circuit for linearly delaying a signal comprises a plurality of control signals. The circuitry further comprises a fine delay element coupled to at least one of the plurality of control signals where the fine delay element comprises logic circuitry configured to provide fine adjustments to the delay of the signal. The circuitry further comprises at least one course delay element coupled to the fine delay element where the at least one course delay element is coupled to at least one of the plurality of control signals. Furthermore, the at least one course delay element comprises logic circuitry configured to provide course adjustments to the delay of the signal. The circuitry for linearly delaying a signal is configured to provide testability and programmability. The circuitry for linearly delay a signal is configured to provide linear delay steps.

  • Patent number: 6261425
    Abstract: An electroplating machine is disclosed as including an electrode positioning apparatus, an electrolyte delivery apparatus, an apparatus for covering a roller, an apparatus for dissolving copper oxide powder in an electrolyte passing through the apparatus, and an apparatus allowing the variation of the distance between two rollers. The electrode positioning apparatus has a first open end and a second end joined by two sets of connecting members. The electrolyte delivery apparatus includes a pipe connected to a source of electrolyte and a nozzle through which the electrolyte is deliverable to an electrode mounted on the electrode positioning apparatus. The electrode positioning and the electrolyte delivery apparatus are slidably engageable with each other. As to the apparatus allowing the variation of the distance between an upper roller and a lower roller, such includes a primary part attachable to a wall of the electroplating machine, and a second part movable relative to the primary part.

The electrode positioning apparatus has a first open end and a second end joined by two sets of connecting members, in which the connecting members in each set are parallel to one another and equally spaced from the adjacent member. The electrolyte delivery apparatus includes a pipe connected to a source of electrolyte and a nozzle through which the electrolyte is deliverable to an electrode mounted on the electrode positioning apparatus. The covering apparatus is elongate in shape and includes a cavity for accommodating a majority part of the outside surface of a roller.
