  • Patent number: 9929052
    Abstract: A wafer is processed by transferring a wafer to a holding surface of a chuck table by using a suction pad. The front side of the wafer is held through a protective tape on the holding surface under suction. The suction pad is then removed from the back side of the wafer and the back side of the wafer is ground, thereby thinning the wafer and also dividing the wafer into individual device chips. The wafer is mounted on the holding surface while held by the suction pad. The wafer is sandwiched between the suction pad and the holding surface when the suction force is removed. A suction force is applied to the holding surface to thereby hold the front side of the wafer through the protective tape on the holding surface, and the suction pad is then removed from the back side of the wafer.

  • Patent number: 9912557
    Abstract: A node information detection apparatus identifies the type of an Operating System (OS) operating on a node that is connected via a network. A message transmission unit 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 receives a response message from the node that received the transmission message. An OS type identification unit identifies the type of OS operating on the node on the basis of the contents of the response message received from the node or on the basis of presence or absence of a response message from the node.

  • Patent number: 9800541
    Abstract: Provided is a communication system that includes first and second communication devices operating in conformance with IPv6 requirements, in which the first communication device (100) determines whether an own IP address for communication is utilized or not by monitoring a communication status, generates a response request message requesting a response message to the second communication device when the own IP address is determined to be no longer required, designates the own IP address as a destination of the response message in the response request message, and transmits the response request message to the second communication device (200) during a period when a Neighbor Cache entry related to the own IP address in the second communication device is in STALE state after transition from REACHABLE state.

  • Patent number: 9755833
    Abstract: An identification information management system according to the present invention comprises a plurality of terminals communicable with servers and a site management apparatus which manages site containing the terminals. The terminal has an identification information processing unit which assuming that a one-way hash function is f(x) and a terminal-unique ID is a, generates values x satisfying a conditional equation f(x)=a as identification information. When acquiring multiple items of identification information, the site management apparatus substitutes the identification information as the value x into f(x) and decides whether f(x)=a is satisfied, thereby deciding the terminals.

  • Patent number: 9679022
    Abstract: A node information storage unit stores an entry in which an address and a record type are associated with a host name. An address translating unit translates an address of a record type different from a record type received from a terminal device in the entry into an address of the received record type based on a predetermined rule. An entry searching unit searches the node information storage unit, and specifies an entry corresponding to a host name received from the terminal device. A search result transmitting unit transmits an address included in the specified entry to the terminal device.

  • Patent number: 9528031
    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.
