  • Publication number: 20110078315
    Abstract: A communication system comprises a NAT device, a terminal device, and a communication control device. The communication control device comprises a first storage unit that stores a NAT address, a first receiving unit that receives a type request signal, a first determination unit that determines whether the NAT address matching a source IP address of the type request signal is stored in the first storage unit, and a first transmitting unit that transmits the type information associated with the NAT address matching the source IP address to the terminal device. The terminal device comprises a second transmitting unit that transmits the type request signal, a second receiving unit that receives the type information, and a communication control unit that performs Peer to Peer communication with another terminal device that is subordinate to another NAT device by performing communication using a method to establish communication based on the received type information.

  • Publication number: 20090317780
    Abstract: The present invention relates to a tooth which is used in a dental arch model with which dental students can experience dental works in the oral cavity and practice treatments. More specifically, the present invention relates to a tooth composition for formation trainings such as abutment tooth formation and cavity preparation. Since conventionally used dental arch models have a grinding sensation different from a natural tooth, dental students having completed formation trainings such as abutment tooth formation and cavity preparation by using these conventional models are frequently puzzled to have different grinding and handling properties upon dental works in the oral cavity in practice. That is, these conventional dental arch models are largely different from a natural tooth in grinding sensation including slipperiness and easiness in grinding.

  • Publication number: 20080278436
    Abstract: A dispersion medium is filled in a display section and is dispersed with charged particles that migrates in accordance with a direction of an electric field. An image forming section applies, upon receiving an image forming request, an electric voltage between a first electrode and a second electrode to generate the electric field in the dispersion medium, thereby performing an image forming operation. A refresh controlling section switches, before the image forming section performs the image forming operation, the direction of the electric field alternately at predetermined timing to uniformly disperse the charged particles in the dispersion medium, thereby performing a refresh operation. An image-formation-elapsed-time measuring section measures a first elapsed time from a previous image forming operation performed by the image forming section until the image forming request.
