  • Patent number: 11305320
    Abstract: A method for producing a seamless metal pipe includes the steps of: preparing a billet having a diameter (B); heating the billet; forming, in a center part of a rear end of the heated billet, a hole including four grooves extending in an axial direction of the billet, the grooves each having a groove width (D) satisfying Formula (1), a groove height (H) satisfying Formula (2), and a groove depth (L1) satisfying Formula (3); and subjecting the billet provided with the hole to piercing-rolling from a front end thereof by means of a piercing machine.

  • Publication number: 20180023179
    Abstract: A method for producing a plug includes: a step of preparing a plug base metal having a concave portion along a circumferential direction in an outer peripheral surface; and an arc spraying step of spraying a spraying wire rod material onto the outer peripheral surface of the plug base metal by arc spraying to form films containing Fe and Fe oxides on the outer peripheral surface of the plug base metal. The arc spraying step includes: a separating step of separating the outer peripheral surface of the plug base metal into a plurality of regions along an axial direction; and a step of performing arc spraying separately in each of the regions. In the separating step, a boundary between the regions is set at the concave portion. In this way, peeling of films at a connecting portion is prevented, and the lifetime of the plug can be increased.

  • Patent number: 9842503
    Abstract: An object of the present invention is to provide a technique which can enhance a possibility of giving notice of only a detected object in a dead angle area which is significant for a user. A controller causes a notification unit, in a first vehicle, to give notice of a detected object, which is determined to have an influence on a traveling of the first vehicle in a dead angle point which the first vehicle travels from among the detected object which is not detected by the first vehicle but detected by the second vehicle, as a travel influencing object based on a route information of the first vehicle, a current position information of the first vehicle, and a detected object information of the first vehicle and a second vehicle which are obtained by the information receiver.
