  • Patent number: 9497067
    Abstract: An address determination apparatus that determines a valid address that a communication apparatus designates as the address at which a communication starts for indicating the origin of a transmission includes: a duplicate valid address determination means that selects a tentative address, and by an inquiry on a network, determines the existence of a valid address that duplicates the tentative address in the network; a memory means that stores the tentative address as an uncertain address when it is determined by the duplicate valid address determination means that there is no valid address that duplicates the tentative address in the network; and an address determination means that, when a communication apparatus begins communication that designates the address at which the transmission originates, determines the uncertain address that is stored in the memory means as the valid address designated as the address at which the transmission of the communication apparatus originates.

  • Patent number: 9378245
    Abstract: A node information storage means stores an entry of node information in which at least an address and a record type are associated with a host name. A search target record deciding means decides a record type of an entry of a search target from a received virtual record type based on a search rule that is a rule specifying a record type of a search target according to a virtual record type. An entry searching means searches the node information storage means, and specifies an entry that corresponds to the entry specifying information received from the terminal device and has the record type decided by the search target record deciding means. A search result transmitting means transmits node information included in the entry specified by the entry searching means to the terminal device.

  • Patent number: 9363285
    Abstract: The present invention provides a network connection method which prevents connection by virus-infected communication devices or communication devices intended for unauthorized access to a network, and enables connection to the network in a simple manner. A user of a requestor communication device connects to a main network by inserting a cable of the communication device to a port of a network device. When the requestor communication device is connected one-on-one to a reception box by a check-in network inside the network device, check-in is performed using the reception box. When the reception box determines through check-in processing that the requestor communication device satisfies connection qualifications, the reception box switches the network, to which the requestor communication device will be connected, from the check-in network to the main network. The requestor communication device then makes a transition to actual use of the main network.

  • Publication number: 20160068713
    Abstract: Slurry composition and a method of substrate polishing used in chemical mechanical polishing (CMP). The present invention concerns a slurry composition containing a polishing agent and a water soluble polymer. The slurry composition contains a water soluble polymer that has a solubility parameter in the range of 9.0 to 14.0 and that may contain hetero atoms at a level sufficient to lower the polishing rate near the edges of the polished substrate defined as the region within 1 mm of the outer edge of the polished substrate to a level below the mean polishing rate of the polished substrate. The water soluble polymer may have a mean molecular weight in the range of 200 to about 3,000,000, and the mean molecular weight may be in the range of 200 to 110,000 if hetero atoms are present in the main-chain structure and the SP value is under 9.5.

  • Publication number: 20160020971
    Abstract: A node information detection apparatus (2000) identifies the type of an Operating System (OS) operating on a node (3000) that is connected via a network (4000). A message transmission unit (2020) transmits a transmission message to be responded to through IPv6 protocol stack processing that is executed at a kernel level implemented in at least one or more types of OSs. A message reception unit (2040) receives a response message from the node (3000) that received the transmission message. An OS type identification unit (2060) identifies the type of OS operating on the node (3000) on the basis of the contents of the response message received from the node (3000) or on the basis of presence or absence of a response message from the node (3000).

  • Patent number: 8713673
    Abstract: The present invention provides a qualification screening system which is capable of performing qualification screening on a device under qualification screening using a status of information to be updated that is retained by the device under qualification screening without having to know concrete procedures or methods for updating such information. A qualification screening device estimates the status of information to be updated that is retained by the device under qualification screening from a time at which an information update program that updates the information to be updated, which is independent of update procedures or methods, was activated and update processing was last updated, and compares the information with a time of a scheduled issuance of information to be updated, retained in qualification screening condition information of the qualification screening device itself, to perform qualification screening.
