Abstract: According to one embodiment, detection of a foreign object mixed in a container can be efficiently performed. A foreign object detection device includes: a determination unit configured to determine, based on a reading result of a wireless tag obtained by radiating a radio wave for reading the wireless tag for a container housing an article and a data file in which a tag identifier held by a wireless tag attached to a foreign object different from the article is registered, whether the wireless tag attached to the foreign object is read; and a notification unit configured to notify that the foreign object is detected if it is determined that the wireless tag attached to the foreign object is read.

Abstract: A cermet powder for thermal spray coating, which is sprayed on a roll surface of a conveyer roll inside a furnace for heat treating a high tensile strength steel strip thereby to form a coating film, comprises: an alloy powder containing 3 to 8 mass % of Al, 16 to 25 mass % of Cr, 0.1 to 1 mass % of Y, and at least one of Co and Ni as the residual, with respect to the whole amount of the cermet powder; and a ceramic powder containing at least one of 1 to 5 mass % of a boride and 5 to 10 mass % of a carbide, with respect to the whole amount of the cermet powder.

Abstract: An alloy of 3 to 9 weight percent boron with the balance molybdenum for use as a thermal spray coating for articles intended to be exposed to molten zinc.

Abstract: A silicide of a refractory metal such as Cr, Mo, Ta, Nb, W, Zr, Ti and V, preferably CrSi.sub.2 and MoSi.sub.2 are materials that are resistant to attack by molten metals, such as zinc, and which materials can provide coatings for various articles. The method for producing the coated materials is also disclosed.

Abstract: An alloy of 3 to 9 weight percent boron with the balance molybdenum for use as a thermal spray coating for articles intended to be exposed to molten zinc.

Abstract: A package is disclosed which includes an enclosed article, and a thermally shrinkable, synthetic resin film enclosing the article and having opposite, first and second edge portions, the first edge portion being superimposed on and sealed to the second edge portion to form a sealed, overlap portion, the film having perforations arranged in a row in at least one of the first and second edge portions and a coating of a seal-preventive agent provided in part of the overlap portion for weakening the seal in the overlap portion.
