  • Publication number: 20190030980
    Abstract: A terminal sealed portion is formed on an end portion of a hollow rod made of steel. An enclosed space is formed on an inner side of the hollow rod. At an end of the enclosed space, a terminal gap is formed. A volatile powdered rust inhibitor is supplied in the enclosed space. As the volatile powdered rust inhibitor is vaporized, the enclosed space is turned into a rust-inhibiting atmosphere. As the vaporized component of the volatile powdered rust inhibitor is adsorbed to an inner surface of the enclosed space, an inner surface rust-inhibiting film is formed. The vaporized component also enters inside the terminal gap, and forms a terminal rust-inhibiting film.

  • Patent number: 8297092
    Abstract: The reflection portion of the reflection member is moved along the inner surface in the hole of the pipe from the entrance opening of the hole of the pipe to the exit opening of the hole thereof. In this case, the reflection portion is guided by the guide portion provided at both sides of the reflection portion. The shots, which are projected toward the inner surface in the hole of the pipe, reach the reflection portion through the holes of the guide portion of the entrance side, and they are reflected toward the inner surface in the hole of the pipe. Since the shots can be reflected toward the inner surface inside in the hole of the pipe, the tendency that shots may be moved toward the inner surface outside in the hole of the curved portion can be small.
