  • Patent number: 8429935
    Abstract: It arranges a bonding material between a pair of base materials having different heat capacities and in which a difference between thermal expansion coefficients thereof is within 10×10?7/° C.; and bonds the pair of the base materials by the bonding material, by irradiating electromagnetic wave to the bonding material to melt and then harden it, wherein a thermal expansion coefficient at part of the bonding material facing one of the pair of the base materials of which the heat capacity is smaller is smaller than a thermal expansion coefficient at part of the bonding material facing the other of the pair of the base materials of which the heat capacity is larger by a difference within 10×10?7/° C., thereby bonding the base materials of which a difference of thermal expansion coefficients is relatively small, as preventing breakage and crack from occurring and further suppressing a degree of warp.

  • Patent number: 8123582
    Abstract: An airtight container manufacturing method includes the steps of exhausting an inside of a container through a through-hole provided in the container, arranging a plate member having, at its periphery, grooves penetrating the plate member in its plate thickness direction, on an outer surface of the exhausted container, so as to close up the through-hole, and providing a sealant on the plate member. In addition, a cover member covers the plate member via the sealant, and the container is sealed by closing the cover member on the plate member. In the sealing step the sealant is deformed and flows from the adjacent grooves to form a continuous shape and fill a space between the cover member and the outer surface of the container and along the periphery of the plate member.
