  • Publication number: 20110167162
    Abstract: The purpose of the present invention is to provide an Internet connection system which is capable of benefiting from the IPv6 by relatively easy means and in which manufacturers of client-side devices can create added values for users. IPv6 packets are transmitted by a tunneling connection between a home network and a server on the Internet. Also terminal devices present in the home network can be uniquely recognized and controlled from outside via the server. Since all communications are performed via the server on the Internet regardless of the carrier and the ISP, the terminal device and all connections to the terminal device can be freely configured and controlled by the owner or the manufacturer of the server on the Internet.

  • Publication number: 20110114232
    Abstract: The present invention aims at providing: a method for manufacturing such a kind of gasket-oriented steel plate excellent in elasticity and formability, in a manner to allow for reduction of a breaking elongation of the steel plate to thereby improve a formability (punchability) thereof while improving a proof stress of the steel plate against a repeated stress from a discharge valve to thereby maintain a higher elasticity of the steel plate; and a gasket able to withstand the repeated stress from the discharge valve. The manufacturing method of a gasket-oriented steel plate of the present invention comprises the steps of: annealing a starting steel material having a composition of: Mn less than 0.5%, Ni less than 2.0%, and Cr less than 12.0%; and subsequently temper rolling the annealed starting steel material at a rolling reduction ratio of 10% or more; and the gasket of the present invention is formed by adopting a gasket-oriented steel plate obtained by the above manufacturing method.

  • Publication number: 20070005879
    Abstract: When update data stored in portable storage media are distributed to update data, the data updatable frequency can be freely restricted at the distribution source of the update data. A data updatable upper limit frequency and an update frequency at which data update is carried out are stored in an update-frequency data storing portion 112 of an external storage medium 103. On the basis of these update-frequency data, it is judged by an update permission judging portion 110 whether there is data update permission in a terminal 102. If there is update permission, the update data is delivered to an update data reading portion 109 in the terminal 102, and the data update is carried out on the basis of the update data by a post-update data restoring portion 107 of the terminal 102, and the post-update data is stored in an in-terminal data storing portion 104. When the data update is carried out, update-frequency data is updated by an update frequency updating portion 111.
