  • Publication number: 20230320388
    Abstract: A sterilizing device evenly irradiating an entire surface of a food with electron beam to provide a sterilizing effect based on the electron beam to the entire surface is provided. The sterilizing device includes: an electron-beam irradiator unit 10 configured to irradiate a process-target object (such as a raw egg) 40 with electron beam EB; a placement stage 22 for the process-target object 40; and a slit SL arranged between the process-target object 40 and the electron-beam irradiator unit 10, the slit unit SL includes a plurality of openings, and is arranged to be upper than a high portion of the process-target object 40. In this manner, since the process-target object 40 is irradiated with the electron beam EB through the slit SL, its entire surface can be more evenly irradiated with the electron beam, and a sterilizing effect based on the electron beam can be provided to the entire surface.

  • Patent number: 7675587
    Abstract: The polarizing plate of the invention comprises a norbornene resin film, a polyurethane layer, an adhesive layer and a polarizing film which are laminated in this order. The polarizing plate exhibits excellent adhesion between the optical film and the polarizing film, is excellent also in properties such as heat resistance and chemical resistance, rarely suffers delamination and distortion even if it is used for a long period of time, and has high reliability. The polarizing plate can be obtained by, for example, a process comprising steps of forming a polyurethane layer on a surface of a norbornene resin film and bonding a polarizing film to the polyurethane layer through an adhesive.
