A packaging bag including a polyester-based multilayer film. The multilayer film includes at least: an innermost layer formed of a biaxially stretched polyethylene terephthalate film; a layer formed of polybutylene terephthalate; and/or a layer formed of a blend of polyethylene terephthalate and polybutylene terephthalate. The biaxially stretched polyethylene terephthalate film has a heat sealing portion that is amorphized or low-crystallized by laser light irradiation. The packaging bag is formed by allowing the innermost layers of the polyester-based multilayer film to be opposed to and superimposed on each other, and heat sealing the heat sealing portions.

A structural body has an inner layer formed of a resin which does not transmit light with a specific wavelength, an outer layer stacked on the inner layer and formed of a resin which transmits the light with the specific wavelength, and a fine periodic structure provided on at least part of a surface of the inner layer facing the outer layer and having a plurality of photodecomposition generated convex and concave portions. The plurality of convex and concave portions of the fine periodic structure is formed alternatively, and horizontally and vertically with substantially equal intervals in between along the surface of the inner layer facing the outer layer.

A defoaming method capable of destroying foams generated when a container is filled with drink, or the like, efficiently at a high speed and destroying foams effectively even in the case of a container having a narrow mouth. Liquid surface () in a container () is irradiated with pulse-like light () and a pulse-like sound wave () is generated from an irradiated point () as a sound source. The pulse-like sound wave thus generated propagates from the sound source as a strong spherical wave to reach a bubble () and to destroy the bubble. It can also destroy a bubble located at a place remote from the optical path quickly, thus destroying bubbles efficiently at a high speed. Alternatively, pulse-like light is condensed at a gas portion above the liquid surface and the bubbles can be destroyed with a shock wave generated by breakdown phenomenon.

Defoaming method

Decoration of a material is enabled with a high degree of recycling properties while satisfying the requirements for putting a structural color into practical use on the industrial scale. Furthermore, whether an object is genuine or not can be verified easily, and reusing by peeling as in the case of a hologram seal is prevented. A cavityhaving a periodic structurecausing optical diffraction is formed in the inside of a substrate, and a periodic structurecausing optical diffraction is formed on part or the whole of the substrate. These cavity interface periodic structureand the substrate surface periodic structurehave a regular arrangement developing a structural color. In addition, by bringing a functional material to be in contact with the substrate surface periodic structure, development of a structural color by the substrate surface periodic structureis suppressed, thereby enabling a structural color developed by the cavity interface periodic structureto be read.

An improved process for treating waste gas from a nuclear power plant to recover radioactive rare gases such as Kr and Xe therefrom. The waste gas is treated with titanium, zirconium or alloys thereof to remove oxygen present in the waste gas.
