摘要:
Gas distribution units of fluidized bed reactors are configured to direct thermally decomposable compounds to the center portion of the reactor and away from the reactor wall to prevent deposition of material on the reactor wall and process for producing polycrystalline silicon product in a reactor that reduce the amount of silicon which deposits on the reactor wall.

摘要:
Processes for producing polycrystalline silicon by thermal decomposition of trichlorosilane are disclosed. The processes generally involve thermal decomposition of trichlorosilane in a fluidized bed reactor operated at reaction conditions that result in a high rate of productivity relative to conventional production processes.
摘要:
A system and method for slicing an ingot into wafers using the wire saw process. A slurry collection system collects and supplies slurry to a slurry handling system for controlling temperatures and/or flow rates of the slurry thereby providing slurry output at a controlled temperature and/or a controlled flow rate to slicing system for cutting the ingot, which may be preheated.
摘要:
The present invention relates to a computer-implemented method, system and computer readable medium for providing context-based listing services. The method comprises registering at least one first service provider with an second service provider wherein registering comprises that the first service provider provides the information via a communication network to the second service provider and it validates the information. Validating comprises identify the location of the first service provider and/or request to at least one predefined user located nearby the location of the first service provider. At least one user requests the second service provider for the information via the communication network. At least one user retrieves the information and provides ranking to category of services so as to update the information in the second service provider.
摘要:
A method, a system, and a computer program product code for generating a series of still images from an input video file are provided. The series of still images may include, but are not limited to, a comic strip and a storyboard. The method includes extracting audio and visual frames from the video file. Thereafter, basic units of the video file are identified. The basic units are exposition (beginning), conflict (middle), and resolution (end). Thereafter, key frames are extracted from the basic units based on at least one of audio frames, visual frames, and a combination of the visual frames and the audio frames. Then, the extracted key frames are manipulated to output a series of still images. Subsequently, narration in the form of audio or text is attached to the still images to generate at least one of comic strips and storyboards.
