摘要:
There are provided a radiation-proof resin composition that is excellent in mechanical characteristics even after exposure to harsh radiation (with 2.5 MGy), that exhibits a suitable radiation-resistant properties by a small amount of mixed additives, and that can suppress the blooming of the additives, and a radiation-resistant wire/cable. The radiation-resistant resin composition is obtained by adding 0.3 to 1.0 parts by mass of a salicylate-based UV absorber, 0.3 to 5 parts by mass of a benzotriazole-based UV absorber, and 0.3 to 5 parts by mass of a triazine-based UV absorber to 100 parts by mass of a polyolefin-based resin.

摘要:
An image forming device including a photosensitive member, a development device and a thermal treating device is provided to form an image on a sheet of paper. The development device uses pressure rollers to develop the paper under pressure and includes a mechanism for varying the pressure. A movable shutter controls the amount of radiant heat provided by the thermal treatment device. When the power is turned off, the shutter closes to prevent further heating. The image forming device also includes a device for removing gases formed during the image forming process.
摘要:
A positive ion of an isomer is generated in an ion source and introduced into a target chamber filled with a target alkali metal so that it is dissociated into a neutral fragment which is then subjected to charge inversion to generate a negative ion. By measuring the mass spectrum of the negative ion, the isomer can be detected at a higher resolution than has been possible by CID and other conventional mass spectroscopic techniques.
