  • Patent number: 11478850
    Abstract: A method to produce metallic beryllium spheres with high sphericity in a large quantity efficiently at a low cost is provided herein. The method of continuously producing metal beryllium spheres comprises the steps of: collecting granulated beryllium spheres produced by charging beryllium powder into a rotary kiln; classifying the collected beryllium spheres by particle size with an automatic sieve; and crushing particles of beryllium spheres of non-target diameters and mixing them with the raw material beryllium powder for reuse. The rotary kiln has a core tube the inner surface of which is coated with beryllium oxide by sintering the slurry coating of beryllium hydroxide applied after alkaline silica treatment.

  • Publication number: 20190047772
    Abstract: Provided is a heating pouch that can be heated in hot water and in a microwave. That is, the heating pouch includes a bag sheet provided with an easy peel pressure releasing seal part. In the pressure releasing seal part, one part of a sheet constituting the bag sheet and another part thereof are adhered so as to overlap each other. The pressure releasing seal part peels off when internal pressure rises, to form a degassing passage that communicates between an inside and an outside of the bag sheet. The pressure releasing seal part is provided with an easy peel layer and a skin layer. The skin layer is a resin layer constituting a seal surface that coats at least one of the one part and the other part of the sheet and which adheres to the other part which is not coated. The skin layer has a higher seal strength at 100 degrees centigrade than the easy peel layer.

  • Patent number: 6855356
    Abstract: A packaging body for heat processing a material retained therein is basically formed of a plastic base material having side joining sections, and end sides. The side joining sections and end sides are superposed and connected together to form a bag for filling the material. A sealant layer is deposited on at least one of the end sides to connect the end sides together through the sealant layer to thereby form a vapor communication joining section at the end sides. The sealant layer has a peeling off property from 0 to 1,200 gf/15 mm at 90° C. and a peeling off property of equal to or more than 3 kgf/15 mm at a room temperature. Thus, only when the packaging body is heated more than 90° C., the vapor communication joining section is only opened to release pressure inside the packaging body.
