  • Publication number: 20230390764
    Abstract: The present disclosure provides a microchannel device that has a channel sandwiched between channel walls formed in an inside of a porous substrate, wherein the channel wall contains a thermoplastic resin and a colorant, and wherein an abundance ratio of the colorant is higher in the porous substrate surface area of the channel wall than in an internal area of the channel wall. In the configuration of the present disclosure, since more of the colorant exist on the surface side of the porous substrate in the channel wall, the visibility of the channel is increased, and in addition, since the amount of the colorant in the internal portion of the channel wall is small, the elution of the ions contained in the colorant into the specimen is suppressed, and the measurement accuracy is increased.

  • Patent number: 9396022
    Abstract: A first device starts to transfer memory data related to a virtual machine running on the first device to a second device connected to the first device via a switch device. When an accumulated amount of transferred memory data exceeds a first threshold, the first device stops packet transmission performed by the virtual machine and transmits a prior shut-down notice to the second device. The first device shuts down the virtual machine when the accumulated amount exceeds a second threshold. The second device transmits, upon receiving the prior shut-down notice, a first control message to the switch device and the first device and causes a virtual network interface to start reception of packets destined for the virtual machine. When the memory transfer is completed, the second device starts up the virtual machine to start the packet transmission and outputs packets held in the virtual network interface to the virtual machine.

  • Patent number: 9197585
    Abstract: An apparatus relays a packet transmitted from and to an information processor via plurality of ports. The apparatus stores, in a memory, first information identifying the information processor in association with a port from which the packet is to be transmitted. When a first packet is received via a first port, the apparatus determines whether second information contained in the first packet and identifying a transmission destination of the first packet is stored in the memory. When the second information is stored in the memory, the apparatus transmits the first packet from a second port associated with the second information, and otherwise transmits the first packet from third ports that are sequentially selected, from among the plurality of ports other than the first port, in variable order that is dynamically determined based on a current traffic state of the plurality of ports.

  • Patent number: 9001692
    Abstract: A route calculation apparatus calculates an intra-domain route in a target domain assigned with the route calculation apparatus. The intra-domain route is a part of a route for a target path in a network divided into plural domains. Each of the plural domains includes at least one node device. The target path passes through transit domains out of the plural domains from a source node device included in a source domain to a destination node device included in a destination domain. The route calculation apparatus includes a calculator and a route calculation requester. The calculator calculates the intra-domain route in the target domain. The route calculation requester requests a first route calculation apparatus assigned to the destination domain to calculate an intra-domain route in the destination domain when the target domain is one of the plural domains except the destination domain and except domains adjacent to the destination domain.
