20140357821 | LOW-TEMPERATURE-RESISTANT FLUORINE-CONTAINING ELASTOMER AND PREPARATION METHOD THEREFOR - The present invention provides a low-temperature-resistant fluorine-containing elastomer formed through polymerization of the comonomers: 40-80 mol % 1,1-vinylidene fluoride, 2-10 mol % tetrafluoroethylene, 10-30 mol % perfluoro(alkyl vinyl ether), and 1-10 mol % vulcanization monomer. The present invention further provides a preparation method of the fluorine-containing elastomer. In the present invention, on basis of a large number of experiments, the contents of the comonomers of the fluorine-containing elastomer are adjusted, so that the low temperature performance thereof is significantly improved, and the low-temperature retraction temperature TR-10<−40. Moreover, the rate of the volume change of the fluorine-containing elastomer in methanol decreases, and the oil resistance and the solvent resistance are improved, thereby improving the oil resistant performance and solvent resistant performance of the fluorine-containing elastomer. | 12-04-2014 |

20140087373 | Enclosed unit for rapid detection of a target nucleic acid amplification product - The invention relates to a method for rapid detection of a target nucleic acid amplification product while preventing cross-contamination between target nucleic acid amplification products and avoiding false positives, comprising the steps of: a) leaving the reaction tube unopened after the amplification reaction is finished, so as to prevent the target nucleic acid amplification product from leaking out and resulting in contamination; b) placing the unopened reaction tube inside an enclosed unit, making the target nucleic acid amplification product be transferred to a test strip from the reaction tube in a physically enclosed environment; c) performing detection in a visual read-out manner, and determining the result; d) discarding the enclosed unit in a safety place as a whole without opening it after the detection. The invention also relates to a totally enclosed unit for detecting a target nucleic acid amplification product, and still relates to applications of the totally enclosed rapid detection unit in detection of infectious pathogens, food industry, agriculture, livestock husbandry, customs quarantine control, and determination of DNA. | 03-27-2014 |

20160070834 | AUGMENTED SIMULATION METHOD FOR WAVEFORM PROPAGATION IN DELAY CALCULATION - A system and a method are disclosed for performing static timing analysis. Information describing a distorted input waveform is received by a static timing analyzer. A transition time of the distorted input waveform is determined. Based on the determined input transition time a nominal input waveform and a corresponding nominal output waveform are received. An input waveform distortion is computed based on the nominal input waveform and the distorted input waveform. An output waveform distortion is computed based on an augmented circuit and the input waveform distortion. A distorted output waveform is computed based on the nominal output waveform and the output waveform distortion. The waveforms are represented using the distortion values which are smaller than the actual waveform values, thereby allowing for compact representation. A time-shifted version of an uncoupled input waveform is used to perform conservative timing analysis of circuits that accounts for crosstalk in the circuit. | 03-10-2016 |
