  • Patent number: 11149882
    Abstract: A threaded connection includes a pin including a wedge male thread having a varying-thread-width portion and a box including a wedge female thread having a varying-thread-width portion. The threaded connection is constructed such that, when both stab flanks and load flanks of the male thread of the pin contact the box, the shoulder on the pin is not in contact with the shoulder on the pin, and, with a further rotation in the make-up direction, the shoulder on the pin is capable of contacting the shoulder on the pin before the threads (i.e. male and female threads) yield.

  • Publication number: 20210231240
    Abstract: An object of the present invention is to provide a threaded connection that has high torque and still requires reduced machining time for the thread. A threaded connection (1) connects a pair of pipes. The threaded connection (1) includes a pin (10) and a box (20). The pin (10) has a male thread (11) on its outer diameter. The box (20) has a female thread (21) on its inner diameter, the female thread corresponding to the male thread (11). The box (20) and the pin (10) are made up. The male thread (11) includes a constant-thread-width portion (111) and a varying-thread-width portion (112). The constant-thread-width portion (111) has a constant thread-groove width. The varying-thread-width portion (112) has a thread-groove width equal to or larger than the groove width of the constant-thread-width portion (111) and gradually increasing, going from the constant-thread-width portion (111) toward the tip of the pin (10).

  • Patent number: 9819912
    Abstract: A technique useful for searching which part of a predetermined area a person who has not yet reached a target position in the predetermined area until a scheduled time, is located. A boarding passenger management device and a boarding passenger reception terminal obtain a boarding passenger management number of the person who enters a boarding lobby, a monitoring camera captures an image of the person, monitoring cameras installed in association with multiple division areas capture an image of each of the division areas. The boarding passenger management device identifies the person who has not yet reached the boarding gate even though it is after the scheduled time, and the boarding passenger management device and the face feature quantity search device identify a division area where an image of the person considered to be a not-yet arrived target person is captured.

  • Patent number: 9083554
    Abstract: When an internal terminal (TM1 to TMn) replaced with another terminal due to the breakdown or the model upgrading and the DHCP function allocates a new private address for the MAC address of the terminal after replacement, the newly allocated private address is managed in association with physical ports (PP1 to PPn) in an expansion NAPT table. Then, in this state, when an IP packet is delivered from an external terminal (TM0) on the side of a WAN(2), the transmission destination address of this IP packet is converted to the private address of the internal terminal after conversion in accordance with the expansion NAPT table using the physical ports as a key.

  • Patent number: 8902789
    Abstract: A network management system which can easily rebuild the system even when a switch in the configuration of cars occurs. A monitor apparatus including monitor cameras (1-1˜1-4, . . . ) and recording devices (1-5, . . . ) in each car (21a, 21b, . . . ) is networked. Each intra-car network is constructed as a LAN, a router (1-10 (RT1), . . . ) is connected to the LAN in each car, and an inter-car network is constructed as a WAN. The same apparatus in each car and apparatuses provided at the same positions are connected to a port of the same port number and the same LAN address is allocated to such an apparatus. As for an access from a WAN side, which apparatus is accessed is defined only by a difference in port number. Network information of the car switched car can be set merely by switching the setting of the WAN address of the router, . . . .
