    摘要: A composite data detector having first and second data detectors. The second detector of the invention starts in a known state and only runs as long as is necessary before being switched off and handing control back over to the smaller detector. Therefore, the composite data detector of the invention consumes less power than the known composite data detector and estimates bits with higher accuracy.

    摘要: A system and method for acquisition signal error estimation is provided which uses one or more past values of the sequence to determine the nearest ideal sample value without comparing the received sample value to the potential sample values. According to one embodiment, the nearest ideal sample value is selected based on the received sample value and values of three consecutive samples. According to another embodiment, the nearest ideal sample value is selected based on the received sample value and a value of an immediately preceding sample. According yet to another embodiment, the nearest ideal sample value is selected based on the received sample value and a value of a previous sample. The acquisition signal error estimator maybe used in conjunction with gain, DC offset, or magneto-resistive asymmetry control loops in a sampled amplitude read channel.

    摘要: Magnetic separators are used for treating silicon-containing materials from chlorosilane reactors to remove magnetically influenced components in the silicon-containing materials. The removal of such impurities allows for enhanced reactivity of the silicon-containing materials in processes wherein the silicon-containing materials are raw materials for the production of silicon based compounds, such as, for example, basic alkylhalosilanes such as dimethyldichlorosilane, methyldichlorosilane, and other chlorosilanes such as trichlorosilane, which chlorosilanes are useful in the preparation of valuable silicon-containing products.

    摘要: A process for the production of monosilanes from the high-boiling residue resulting from the reaction of hydrogen chloride with silicon metalloid in a process typically referred to as the "direct process." The process comprises contacting a high-boiling residue resulting from the reaction of hydrogen chloride and silicon metalloid, with hydrogen gas in the presence of a catalytic amount of aluminum trichloride effective in promoting conversion of the high-boiling residue to monosilanes. The present process results in conversion of the high-boiling residue to monosilanes. At least a portion of the aluminum trichloride catalyst required for conduct of the process may be formed in situ during conduct of the direct process and isolation of the high-boiling residue.
