  • Patent number: 8985451
    Abstract: A communication apparatus performing communication in a noncontact manner is provided. The communication apparatus includes a transmission control unit configured to transmit a command; a timeout period checking unit configured to check whether a timeout period during which a response to the command is waited for has elapsed; a retransmission control unit configured to retransmit the command only after the timeout period has elapsed; an error checking unit configured to check whether data received within the timeout period has an error; and a processing unit configured to regard the data received within the timeout period as a correct response to the command if the data does not have an error and perform a process in accordance with the response. If the data received within the timeout period has an error, the retransmission control unit does not retransmit the command and the timeout period checking unit continues to check whether the timeout period has elapsed.

  • Publication number: 20130071741
    Abstract: A negative electrode for a secondary battery according to the present invention has a collector and a negative electrode active material layer formed on a surface of the collector and containing negative electrode active material particles. In the negative electrode active material layer, an insulating material is arranged between the negative electrode active material particles so as not to develop conductivity by a percolation path throughout the negative electrode active material layer. It is possible in this configuration to effectively prevent the occurrence of a short-circuit current due to an internal short circuit and the generation of heat due to such short-circuit current flow in the secondary battery while securing the battery performance of the secondary battery.

  • Publication number: 20120216975
    Abstract: A non-woven mat may be generated using synthetic wood pulp and short glass fibers. The non-woven mat may be made in very thin, light weight configurations for various uses. The synthetic wood pulp may serve as a dispersant to disperse the glass fibers in a mixture prior to using paper making techniques to form the mat. A heat flux may bind the glass fibers by melting the synthetic wood pulp to form a mat. The mat may be calendered. In some embodiments, the mat may have a secondary application of a polymer, such as PVDF or PMMA which may further strengthen the mat.
