Abstract: A wire including a wire body that is made of metal, and a protector that is made of resin, that covers an outer periphery of the wire body, and that is integrally molded with the wire body.

Abstract: The acquisition unit 41B acquires a target image indicating a target object of inspection. The detection unit 42B detects, on the basis of a group of images each of which indicates the target object in a normal state, the target image that indicates the target object that is not in the normal state among the target images that the acquisition unit 41B acquires.

Abstract: An aluminum plate (103) is overlaid on a steel plate (102). A distal end (113) of a button component (101) is pushed in from the obverse surface side of the aluminum plate (103), and the distal end (113) is abutted against the steel plate (102) by applying a first pressure to the button component (101) made of steel without heating. The distal end (113) of the button component (101) and the steel plate (102) are welded by resistance spot welding while applying a second pressure lower than the first pressure to the button component (101).

Abstract: A pipe joint includes a socket, a plug, a retaining unit for preventing the plug from being drawn out from the socket, a seal ring arranged at an inner periphery of the socket and a hold ring arranged at the inner periphery of the socket for preventing the seal ring from being moved. A projected portion is formed at a position of the inner periphery of the socket for attaching the hold ring, and the hold ring includes a notched portion or a recess portion for engaging with the projected portion, and a projected portion projected in a direction of an inserting port of the plug, and the plug includes a ring-like projected portion for engaging with the retaining unit, and a recess portion or a flat portion provided at the ring-like projected portion to engage with the projected portion of the hold ring.
