Abstract:
The present invention relates to reactor tubes packed with a catalyst system employed to deliberately bias process gas flow toward the hot tube segment and away from the cold segment in order to reduce the circumferential tube temperature variation.
Abstract:
Methods of ONO integration into MOS flow are provided. In one embodiment, the method comprises: (i) forming a pad dielectric layer above a MOS device region of a substrate; and (ii) forming a patterned dielectric stack above a non-volatile device region of the substrate, the patterned dielectric stack comprising a tunnel layer, a charge-trapping layer, and a sacrificial top layer, the charge-trapping layer comprising multiple layers including a first nitride layer formed on the tunnel layer and a second nitride layer, wherein the first nitride layer is oxygen rich relative to the second nitride layer. Other embodiments are also described.
Abstract:
A tubular reactor and method for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.
Abstract:
Disclosed is a regenerator, a regeneration process, and a liquid polymer mixture for periodic cooling, storing, and heating of atmospheric gas. The regenerator, the regeneration process, and the liquid polymer mixture involve a liquid polymer that remains in contact with a thermally conductive solid material during a first operational period and a second operational period of a regeneration process.
Abstract:
A tubular reactor for producing a product mixture in a tubular reactor where the tubular reactor comprises an internal catalytic insert with cup-shaped structures having orifices for forming fluid jets for impinging the fluid on the tube wall. Jet impingement is used to improve heat transfer between the fluid in the tube and the tube wall in a non-adiabatic reactor. The tubular reactor and method may be used for endothermic reactions such as steam methane reforming and for exothermic reactions such as methanation.
Abstract:
The present invention relates to a liquid crystal display of a time divisional color display, which includes a plurality of pixels having liquid crystal capacitors, respectively, and light is not supplied to some pixels and light supplied to other pixels. Preferably, data voltages are applied to the pixels to which light is not supplied and data voltages are not applied to the pixel to which light is supplied. Accordingly, since a liquid crystal panel assembly is divided into several areas to be scanned sequentially and a light source of a light source unit corresponding to the area being scanned is maintained in light-off state, it is possible to secure enough data scan time as well as to increase light-on-time of the light sources. With this, time to charge electric charges of the liquid crystal capacitors is increased to improve image quality, and, according as light-on time of the light sources is increased, clearness of the image quality is also increased.
Abstract:
A polyester microfiber velveteen coral weft blanket, adopting polyester filament or polyester and nylon multi-filament of 0.58 dtex or smaller specification as row stock, 110˜167 dtex polyester FDY (fully drawn yarn) or DTY (draw texturized yarn) as ground thread, said polyester filament or polyester and nylon multi-filament takes up 40˜80% of the component, said 110˜167 dtex polyester FDY (fully drawn yarn) or DTY (draw texturized yarn) takes up 60˜20%, said percentages are mass percents; the production processes are: raw stock preparation, weave on the circular slitting weft knitting machine, heat setting, dyeing or printing, finishing, napping, wrong side shearing, heat setting, finished blanket, inspection and packing, the pile has unique style reaching that of the submarine coral, providing the product with thermal property, lightness, soft handle that can sufficiently meet the requirements of the market, and the techniques are reasonable, effective and suitable for the production of blankets.

Abstract:
Embodiments disclosed relate to wafer level burn-in of integrated circuits on a semiconductor wafer. One embodiment disclosed performs monitored burn-in on sample wafers from a manufactured lot of wafers and determines a burn-in time for the lot from results of the monitored burn-in. The burn-in on remaining wafers from the lot is then performed for the burn-in time that was determined. Another embodiment disclosed performs burn-in on wafers from a manufactured lot of wafers while monitoring in real-time the burn-in for a subset of wafers in the lot. Using fallout data from the real-time monitoring, a determination is made as to whether the burn-in time is sufficient. If the burn-in time is determined to be sufficient, then the burn-in of the lot is stopped.
