  • Patent number: 8350050
    Abstract: High-quality bis-(1(2)H-tetrazol-5-yl)amine and a method for easily, safely, and inexpensively producing the compound are provided. The method for producing bis-(1(2)H-tetrazol-5-yl)amine includes the steps of heating to 50 to 120° C. a solution mixture in which a necessary amount of an azide salt and a dicyanamide salt in an amount corresponding to 1 to 80 wt % of a necessary amount are added to a solvent, adding an acid in an amount of 1.54 to 2.22 chemical equivalents of the dicyanamide salt in the solution mixture to carry out a reaction at 50 to 120° C., and then adding an acid and a dicyanamide salt solution in which the remaining dicyanamide salt is dissolved in a solvent to promote the reaction. Bis-(1(2)H-tetrazol-5-yl)amine is obtained according to the production method.

  • Patent number: 8352832
    Abstract: An error correction code includes a separate error code portion for each of two or more separate burst erasure durations (or burst error durations). For each burst erasure duration, the code can be employed to recover from the burst erasure with a different delay time. Each error code portion has a particular parameter for burst duration (B) and delay (T), meaning that the code can be used to recover from a burst erasure of duration B with delay T. Each error code portion is based on separating the source symbols into sub-symbols and diagonally interleaving the sub-symbols based on the (B,T) parameters for the error code portion. Accordingly, different burst erasures are recovered from with different delays.

  • Patent number: 8349180
    Abstract: Fluid filter elements and assemblies are used to separate contaminants from a fluid, such as oil or fuel, prior to reaching an engine. Fluid filter assemblies may comprise a housing, a filter element, and a filter head. The filter element may be disposed within the filter housing and enclosed by the filter head. Fluid enters the housing and passes through the filter element. The fluid may then exit the assembly. A connector may be used to connect the filter element to the filter head to ensure proper installation and simplify removal of a fouled filter element. The connector permits removable coupling of the filter element to the filter head and resists unintentional disengagement to securely couple the filter element to the filter head.

  • Patent number: 8346098
    Abstract: A receiving apparatus is provided, which includes: a photoelectric detector (PD), adapted to generate current signals according to optical signals projected on the PD and digitally modulated at a high or low rate; a first switch, adapted to switch to output the high-rate or low-rate current signals; a first transimpedance amplifier (TIA), adapted to amplify the high-rate current signals into high-rate voltage signals; and a second TIA, adapted to amplify the received low-rate current signals into low-rate voltage signals. Therefore, in the present invention, high-rate and low-rate receiving paths are completely separated. This provides signals with good quality and avoids signal deterioration; and switching between the high-rate and low-rate receiving paths simplifies the structure and lowers costs.
