  • Yb: and Nd: mode-locked oscillators and fiber systems incorporated in solid-state short pulse laser systems
    Patent number: 8509270
    Abstract: The invention describes classes of robust fiber laser systems usable as pulse sources for Nd: or Yb: based regenerative amplifiers intended for industrial settings. The invention modifies adapts and incorporates several recent advances in FCPA systems to use as the input source for this new class of regenerative amplifier.

  • Panel Fastener
    Publication number: 20080073913
    Abstract: A panel fastener comprises casing 1 and casing 2 in lathing engagement. In casing 1, there is mounted a hook with a hook-shaped head and a ring-shaped tail. In the ring-shaped tail, there is mounted an eccentric cam which is interlocked with the inner wall of the hook by a spring tab. The hook is rotary and built into casing 1 with the inner hexagon eccentric shaft. Correspondingly, there is a fixed axis mounted in the casing 2. It features that the said eccentric cam and its eccentric shaft are both made of steel material and that the eccentric shaft is inserted into the connecting hole of the eccentric cam and welded with it together. In that way, the whole structure is suitable for application on panel fasteners with a solid cam, reliable performance, greater locking force and longer service life.
