  • Brake disc with (Longitudinal Vortex Generator)
    Publication number: 20200132146
    Abstract: A ventilated brake disc comprising a pair of annular members, each having a brake application surface and a back surface, a plurality of connection members that connects said pair of annular members and defines, together with said back surface, ventilation channels for passage of cooling air, and a plurality of longitudinal vortex generators (LVG) disposed along the passage of cooling air that generates vortices with a central axis in the downstream direction of the cooling air.

  • Method of manufacturing a core collimating assembly for DWDM devices
    Patent number: 6633701
    Abstract: A method of manufacturing a collimating assembly includes the following steps: preparing a GRIN lens subassembly; preparing a dual-fiber (DF) pigtail subassembly; fitting the GRIN lens subassembly and the DF pigtail subassembly together; applying epoxy onto a junction zone between the GRIN lens subassembly and the DF pigtail subassembly; and baking the junction zone for curing the epoxy thereof until the epoxy spreading uniformly over the junction zone due to the so-called capillarity phenomenon.
