Read e-book online Dynamic Scenarios in Two-State Quantum Dot Lasers: Excited PDF

André Röhm investigates the dynamic houses of two-state lasing quantum dot lasers, with a spotlight on flooring kingdom quenching. With a unique semi-analytical procedure, varied quenching mechanisms are mentioned in an unified framework and confirmed with numerical simulations. The recognized effects and experimental findings are reproduced and parameter dependencies are systematically studied.

There are no size parts since pitch and acceleration are set electronically instead of with curves or cams. 70m. The filling and sealing machine is designed for the automated packaging of sanitary napkins, panty liners or similar products in polyethylene bags. Because of its independent servo drive, the machine can be connected to any production line on the market and can also be connected as an extension to existing Bikoma models. Featuring a new operation philosophy, the FSP 40/50 packaging machine offers: a freely accessible operation side; a back side with an extendable bag magazine for 4,000 bags and more; production up to two hours without refilling of bags; fully automated bag changing without reduction of speed; and a new patented welding system.

Moplen has already been tested on a Reifenhauser Reicofil 4 line, where results included significantly improved nonwoven softness, high spinning speed, filament and nonwoven tenacity not lower than standard polypropylene, and a broader calendering window. This is enabling converters to achieve processing cost savings compared to standard 800 MFR resins. It also has improved barrier properties such as hydrohead, which can be achieved at much lower processing temperatures with significant cost saving in the melt-blown process compared to standard high fluidity resins.

Side-by-side fibre is mainly used to produce a self-crimping effect based on the different physical or chemical properties of the two components in the same fibre. Side-by-side bicomponent fibres are produced, as the name implies, by simultaneously spinning two fibre components together so that they are joined longitudinally. The two components may differ in chemical composition or differ in some property that provides differential expansion or shrinkage, such as molecular weight or degree of crystallisation.
