Adjacent to an opening portion 10 in an FIMS system is provided an enclosure that encloses the operation space of a door and has a second opening portion 31 opposed to the opening portion 10. A curtain nozzle is provided above the upper edge of the opening portion 10 in the upper portion in the enclosure. A purge gas is supplied from the curtain nozzle along a direction from the upper edge to the lower edge of the opening portion. In addition, a gas outlet through which the purge gas flows from the interior of the enclosure out into the exterior is provided on the wall of the enclosure to which the purge gas flowing in the above described direction is directed, whereby an increase in the partial pressure of oxidizing gases in the interior of the FOUP is prevented.

Methods are disclosed for producing highly doped semiconductor materials. Using the invention, one can achieve doping densities that exceed traditional, established carrier saturation limits without deleterious side effects. Additionally, highly doped semiconductor materials are disclosed, as well as improved electronic and optoelectronic devices / components using said materials. The innovative materials and processes enabled by the invention yield significant performance improvements and / or cost reductions for a wide variety of semiconductor-based microelectronic and optoelectronic devices / systems.Materials are grown in an anion-rich environment, which, in the preferred embodiment, are produced by moderate substrate temperatures during growth in an oxygen-poor environment. The materials exhibit fewer non-radiative recombination centers at higher doping concentrations than prior art materials, and the highly doped state of matter can exhibit a minority carrier lifetime dominated by radiative recombination at higher doping levels and higher majority carrier concentrations than achieved in prior art materials. Important applications enabled by these novel materials include high performance electronic or optoelectronic devices, which can be smaller and faster, yet still capture or emit light efficiently, and high performance electronics, such as transistors, which can be smaller and faster, yet cooler.

A process for producing precooked bacon slices comprising the steps of (a) conveying bacon slices through a spiral oven, (b) indirectly cooking the bacon slices in the spiral oven using a cooking medium which is circulated within the oven at a low rate sufficient to prevent the bacon slices from being displaced on the conveyor, and (c) adding steam to the cooking medium as necessary to at least reduce the percentage or substantially eliminate the presence of air in the cooking medium.

A method to start a steady state process for producing normally gaseous, liquid and solid hydrocarbons comprises providing a synthesis gas and catalytically converting the synthesis gas into normally gaseous, liquid or solid hydrocarbons. The process involves using at least a portion of the gaseous hydrocarbons produced as a recycle stream to which hydrogen is added prior to its reintroduction into the reactors and as the activity of the catalyst converting the synthesis gas proceeds from start-up towards a steady state, the amount of recycle stream is reduced.

The present disclosure relates to a fire extinguishing composition generating fire extinguishing substance through high-temperature decomposition; the fire extinguishing composition includes a fire extinguishing material which can be decomposed to release substance with fire extinguishing properties during the heating process; the content of the fire extinguishing material is at least 80 wt %; a pyrotechnic agent is adopted as a heat source and a power source in a process of fire extinguishing; and the purpose of fire extinguishing is achieved by: igniting the pyrotechnic agent, generating a large quantity of fire substance from the fire extinguishing composition in the use of high temperature produced by burning pyrotechnic agent, and the fire substance sprays out together with the pyrotechnic agent. Compared with the traditional aerosol fire extinguishing systems, the gas fire extinguishing systems and the water type extinguishing systems, the present disclosure provides a more efficient and safer fire extinguishing composition.

A method for forming a carbon nanotube array includes the following steps: providing a smooth substrate (11); depositing a metal catalyst layer (21) on a surface of the substrate; heating the treated substrate to a predetermined temperature in flowing protective gas; and introducing a mixture of carbon source gas and protective gas for 5-30 minutes, thus forming a carbon nanotube array (61) extending from the substrate. When the mixture of carbon source gas and protective gas is introduced, a temperature differential greater than 50° C. between the catalyst and its surrounding environment is created by adjusting a flow rate of the carbon source gas. Further, a partial pressure of the carbon source gas is maintained lower than 20%, by adjusting a ratio of the flow rates of the carbon source gas and the protective gas. The carbon nanotubes formed in the carbon nanotube array are well bundled.
