Abstract: The invention relates to a sealing composition which comprises a crosslinkable fluoroelastomer, a crosslinking agent for this elastomer and a reinforcing polyimide resin powder; and seals such as O-rings, made by molding the composition into a prescribed shape and crosslinking the molded article. According to the invention, seals free from metals and sulfur can be made from a fluoroelastomer suitable for the production unit for semiconductor devices without a scatter of physical properties within one seal or among seals, and the obtained seals are lowered in the compression set determined ate the same hardness level to cause little permanent set by compression in use, thus having a prolonged service life.

Abstract: The present invention is a method and an apparatus for imaging a liquid-filling container in which a light emitting unit is provided for emitting and irradiating light onto the container and a light receiving unit is provided for receiving the light transmitted through the container. The object of the present invention is to provide such a method and an apparatus for imaging a liquid-filling container. This method and apparatus assures reliable detection of the surface of liquid filled in a container or of foreign substance mixed in the liquid or present in the container or the container material not only when the container is transparent, but also when the container is a colored container of a dark color such as black, dark green or dark brown or the container has a frosted surface of when the liquid filled in the container has a dark color.

Abstract: The present invention relates to a method and an apparatus for imaging a liquid-filling container in which a plurality of imaging devices each comprising a light emitting unit and a light receiving unit are provided. Light from each light emitting unit is irradiated onto a liquid-filling container and this light transmitted through the container is received by each light receiving unit. The object of the present invention is to provide such method and an apparatus for imaging a liquid-filling container. This method or apparatus allows for simultaneous and highly reliable imaging of two or more kinds of condition of the container. For accomplishing this object, according to the present invention, wavelengths of the lights emitted by the respective light emitting units and received by the respective light receiving units of the imaging devices for imaging the liquid-filling containers are different from each other.

Abstract: In an imaging method including the steps of irradiating light from light emitting means (4) to a target object to be imaged (S) such as a cardboard box, including an identifier marking (3) at a second portion (d2) thereof printed on a first portion (d1) constituting an ornamental design (2) printed on a cardboard box side face (1A) and then receiving the reflected light therefrom by light receiving means (5) so as to image the object (S), the first portion (d1) and the second portion (d2) are provided with different reflection factors for the near-infrared range light from each other. The light emitted from the light emitting means (4) includes a near-infrared range light component and the light receiving means (5) receives the near-infrared range light component for the imaging. With these, even when the marking is printed on a background having a dark color, the marking can be detected accurately and reliably as being distinct from the background.

Abstract: Radioactive stents used in angioplasty on sclerotic coronary arteries without the risk of restenosis can be produced by ion injecting 133Xe into the surfaces of stents as a nuclide that has a shorter half-life and emits a smaller maximum energy of &bgr;-rays than 32p Uniform ion injection is accomplished using an apparatus capable of uniform irradiation of the stents with 133Xe ion beams. The source of 133Xe is a nuclear fission product generated from 235U in the fuel rods in nuclear reactor.

Abstract: Sealing members, such as rolling bearing seal and oil seal, which are not only satisfactory in the fundamental properties required of them, such as sealing performance, heat resistance, mechanical strength and oil resistance, but also excellent in creep and PAG resistances. The member has an elastic part and is made by molding a modified nitrile rubber comprising a butadiene-acrylonitrile-acrylate copolymer and containing an organic peroxide as a vulcanizer, a metal oxide as a vulcanization aid, and a basic silicate as a reinforcing filler.
