Contract notice: Copernicus local land monitoring services production of very high resolution land cover/land use datasets reference years 2012 (geographic extension) and 2018 (new) including change layer
In the Layers window, change Layer
1 blending mode to Lighten.
This allows for angular movement of the mandrels relative to each other, which provides the flexibility to change layer
ratios without needing to change extruder position.
Writing, erasing, or reading the small marks imposes a rather tight tolerance on the laser beam being focused onto the phase change layer. The same holds for the accuracy of the focused beam kept on the center of the track on which the amorphous marks are positioned.
Faster crystallization can be achieved through different materials and clever design of the stack of thin films surrounding the phase change layer. Crystallization times of less than 100 nanoseconds, allowing 8X CD-RWs, represent the state of the art, and 10X-12X CD-RW (12-15Mb/s) will be achieved in the laboratory within the next two years; market introduction could begin in 2003.
The unrecorded phase change layer of a WORM disk is in the amorphous state.
The WORM Phase Change layer has no unstable intermediate state, like in the ablaive Tellurium alloy, which, of course, greatly simplifies the Data-Verify pass for drives using the Phase Change technology.
Black Clawson's seven-layer stretch-film line at Quintec uses five extruders and an Ultraflow feedblock from Extrusion Dies Industries with selector spools to change layer
The RT Feedblock can be configured for two to seven layers and used with a Cloeren selector-plug cartridge or "TopHat" device to change layer
Its Ultraflow I-S coex feedblock incorporates interchangeable flow-path inserts that let you change layer
sequences without having to block off flow channels or disassemble the feedblock.
* Wherever the traces change layers
, the air gap separation of the two associated via pads is minimized (not to exceed trace spacing, if feasible).
"Now you can mix, match, and change layers
around," says president Matt Bangert.
