  • Patent number: 8344332
    Abstract: At a conveying path 10 for continuously carrying a sheet material 1, an electron beam irradiation means 20 is arranged in opposition to at least one surface of the sheet material 1, and at least one surface of the sheet material 1 is sterilized using such an electron beam. The conveying path 10 takes shape of a hollow box surrounding the sheet material, and has an electron beam irradiation area 11 at a part of this area, while keeping a reduced-pressure state ranging from 10 to 80,000 Pa using a pressure reduction means 16. Further, the electron beam irradiation area 11 where the electron beam irradiation means 20 is arranged at least one sub area 12 at each of adjacent hollow box-shaped conveying path 10 at carry-in side and carry-out side of the sheet material, providing the pressure reduction means 16 for depressurizing the sub area 12.

  • Patent number: 8227776
    Abstract: The electron beam irradiating apparatus with the monitoring device has an electron beam irradiating means for irradiating materials in an irradiation chamber. The monitoring device has a photographing means for imaging a lights emitted by irradiating an electron beam to the materials; a storage means that stores state of electron beam irradiation in advance; and a calculating means that processes an image, which is captured by the photographing means, to decide a state of electron beam irradiation. The storage means has stored at least three state of electron beam irradiation and also has stored image luminance associated with those states of electron beam irradiation. The calculating means loads the image, which is captured by the photographing means, to compare the loaded image with the image luminance stored in the storage means, thereby deciding a state of electron beam irradiation.

  • Patent number: 8222614
    Abstract: The apparatus has a rotating body 11 in an irradiation processing chamber 10. Outside the rotating body 11, plural retaining mechanisms 2 are installed at regular interval to retain open-mouthed containers. Above the conveying path, an electron beam generating means 40 is arranged. The rotating body 11 has a rotary shaft 12 that penetrates into the electron beam generating means 40. On the rotary shaft 12, a grid plate 45 of an electron beam source 41 of the electron beam generating means 40 is rotatively installed. On the grid plate 45, plural emission holes 46 are provided at the same interval as that of the retaining mechanisms 2 on the rotating body 11. In an predetermined irradiation area, the emission holes 46 and a irradiation windows 43 on the irradiation processing chamber 10 and the retaining mechanism 2 for holding the container are aligned approximately on the same axes.
