  • Publication number: 20240163247
    Abstract: An edge control device (10) includes: an acquisition unit (15a) configured to acquire information about switching of an edge router accommodating a user's terminal; an instruction unit (15d) configured to instruct a dynamic host configuration protocol (DHCP) server to induce re-acquisition of an internet protocol (IP) address by the user's terminal on the basis of the information about edge router switching acquired by the acquisition unit (15a); and a receiving unit (15e) configured to receive, from a DHCP server, a notification that induction of IP address reacquisition is completed.

  • Patent number: 11970390
    Abstract: The present disclosure provides a method for producing a microchannel device, which can form a channel that has high hydrophobicity, high solvent resistance as well, and also resistance to heat and damage, on demand with high accuracy, and produces the microchannel device at a low cost, while having high productivity. The method for producing a microchannel device includes: forming a channel pattern from a hydrophobic resin on a porous substrate by an electrophotographic method; melting the channel pattern by heat to allow the channel pattern to permeate into the porous substrate, thereby forming a channel in the inside of the porous substrate.

  • Publication number: 20240097980
    Abstract: A common control unit (141A) acquires a configuration input request to a communication device accommodating a user using a network. An individual control unit (142A) identifies a variable group necessary for a command to execute the configuration input based on request content of the configuration input received by the common control unit (141A) and a type of communication device and transmits the identified variable group to the common control unit (141A). A command execution unit (143A) acquires the variable group identified by the individual control unit (141A) from the common control unit (141A), generates a command based on the acquired variable group, and executes the generated command.

  • Patent number: 7794179
    Abstract: A high-strength steel pipe rockbolt has an expansive rockbolt main body prepared by processing a high-strength steel sheet of 1.8-2.3 mm in thickness with a tensile strength of 490-640 N/mm2 and an elongation of 20% or more into a welded pipe and roll-forming the welded pipe into a shaped pipe having one or more concavities extending along an axial direction. Use of the high-strength steel sheet ensures sufficient strength of the shaped pipe regardless of a decrease in thickness. The thin welded pipe is also advantageous in resistance to cracking caused by accumulation of strains introduced during roll-forming, swaging both ends of the welded pipe and hydraulic expansion. Moreover, expansive deformation of the shaped pipe is initiated by injection of a pressurized fluid at a low pressure, so that the expansive deformation is completed in a short time period with an improved working efficiency.

  • Publication number: 20080107488
    Abstract: A lock bolt of a high strength steel pipe, wherein an expansion type lock bolt body is formed of a deformed pipe manufactured by using, as a raw material, a high tension steel plate having a tensile strength of 490 to 640 N/mm2, an elongation of 20% or more, and a plate thickness of 1.8 to 2.3 mm and having a single or a plurality of recessed parts extending in the axial direction of the deformed pipe. Since the high tension steel plate is used in the lock bolt, sufficient strength can be secured for the lock bolt though the steel plate is thin, and cracking due to stains introduced in a molding process, a both end shrinkage process, and a pressurizing/expanding process can be suppressed. Since an expansion start pressure when a pressurized fluid is press-fitted and inflated is also low, a time in which the expansion/deformation is completed can be shortened and workability can also be improved.
