There is provided an exfoliated graphite-resin composite material that has high dispersibility in resins and the like and is easily handled. A thin-walled portion, whose thickness is thinner than a radial direction thickness of the cylindrical tube portion, is formed continuously or intermittently over an entire periphery between an inner peripheral surface of the cylindrical tube portion and an outer peripheral surface of the reel plate in a radial direction of the floor portion. The interconnector is formed of a ceramic composition represented by the composition formula LaO3 in which 0<x<0. This invention finally relates to an interleaving or deinterleaving method which comprises selecting a first number of symbols within a stream of digital data thereby obtaining selected symbols. Furthermore, upon detection of an interruption of the traffic in the first wavelength on the first ring, the access node adds the traffic in a second wavelength of a second optical signal communicated on the second ring. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
