20110092120 | ADHESIVE COMPOSITION AND METHOD - An adhesive composition contains a block copolymer hot melt adhesive and a vapor releasing vapor corrosion inhibitor mixed with the block copolymer hot melt adhesive, the vapor corrosion inhibitor being in the form of particles suspended in the adhesive composition, the particles preferably having a maximum dimension of less than about 30 microns. One improvement results from inclusion in the adhesive mixture of a titanium and/or zirconium containing coupling agent, either separately or as part of the VCI particles. Another improvement results from blending the adhesive mixture in a continuous process using for example a twin screw extruder. As a result, the adhesive mixture has better uniformity and superior viscosity properties during use. | 04-21-2011 |
20120015161 | Water Vapor Permeable Shrinkable-Fabric - A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage. | 01-19-2012 |

20100024716 | METHOD AND APPARATUS FOR CONTROLLING DIAMETER OF A SILICON CRYSTAL INGOT IN A GROWTH PROCESS - An improvement to a method and an apparatus for growing a monocrystalline silicon ingot from silicon melt according to the CZ process. The improvement performs defining an error between a target taper of a meniscus and a measured taper, and translating the taper error into a feedback adjustment to a pull-speed of the silicon ingot. The conventional control model for controlling the CZ process relies on linear control (PID) controlling a non-linear system of quadratic relationship defined in the time domain between the diameter and the pull-speed. The present invention transforms the quadratic relationship in the time domain between the diameter and the pull-speed into a simile, linear relationship in the length domain between a meniscus taper of the ingot and the pull-speed. The present invention applies a linear control (modified PID) which operates in the length domain, and controls a system that has a linear relationship between the ingot taper and the pull-speed in the length domain to control the diameter of a growing silicon ingot. | 02-04-2010 |
20100024718 | Procedure for in-situ determination of thermal gradients at the crystal growth front - A method and apparatus for growing a semiconductor crystal include pulling the semiconductor crystal from melt at a pull speed and modulating the pull speed by combining a periodic pull speed with an average speed. The modulation of the pull speed allows in-situ determination of characteristic temperature gradients in the melt and in the crystal during crystal formation. The temperature gradients may be used to control relevant process parameters that affect morphological stability or intrinsic material properties in the finished crystal such as for instance the target pull speed of the crystal or the melt gap, which determines the thermal gradient in the crystal during growth. | 02-04-2010 |
