  • Patent number: 7706391
    Abstract: In a packet transmission method and device, when a received packet is written in a packet buffer, an address of the packet buffer is stored as a read address for each destination corresponding to a physical port and storing information of the received packet. The read address of a destination designated by the received packet information is read and saved when the received packet is read out of the packet buffer in accordance with a scheduling control. Then, the saved read address is taken out in accordance with an arbitration control and a received packet corresponding to the saved read address is read from the packet buffer.

  • Patent number: 7628841
    Abstract: A process of producing an asymmetric membrane of multicomponent polyimide. The process includes the steps of (1) preparing a multicomponent polyimide blend solution by mixing a polyimide component A having a number-averaged polymerization index NA and a polyimide component B having a number-averaged polymerization index NB, wherein NA and NB satisfies equation 1: 2.35×NA?2.09<NB<450×NA?1.12??1 (2) subjecting the multicomponent polyimide blend solution to further polymerization and imidation reaction, and (3) causing a phase inversion in the resulting multicomponent polyimide blend solution to form an asymmetric membrane. The polyimide component A is raw materials of polyimide A containing a fluorine atom in the chemical structure thereof and/or a polymerization and imidation reaction product of the raw materials.
