  • Patent number: 12023729
    Abstract: The present invention discloses a directional solidification method for a superalloy single crystal blade based on solid-liquid interface steady control. The method establishes effective criteria for withdrawal speed adjustment, i.e. the related position between a macro solid-liquid interface and a thermal baffle, the range between the dendrite tips at the solid-liquid interface, and the difference between the advance speed of the macro solid-liquid interface and the withdrawal speed. With these criteria, the advance of the solid-liquid interface during directional solidification is simulated and a withdrawal speed curve v(t) for the solid-liquid interface steady advancement was obtained. And then, the single crystal blade was prepared.

  • Patent number: 8902887
    Abstract: This invention provides a load-balancing structure for packet switches and its constructing method. In this method, the structure based on self-routing concentrators is divided into two stages, that is, a first stage and a second stage fabric. A virtual output group queue (VOGQ) is appended to each input group port of the first stage fabric, and a reordering buffer (RB) is configured behind each output group port of the second stage fabric. Packets stored in the VOGQ are combined into data blocks with preset length, which is divided into data slices of fixed size, finally each data slice is added an address tag and is delivered to the first stage fabric for self-routing. Once reaching the RB, data slices are recombined into data blocks. This invention solves the packet out-of-sequence problem in the load-balancing Birkhoff-von Neumann switching structure and improves the end-to-end throughput.
