  • Publication number: 20240243933
    Abstract: A management system that manages content data corresponding to a hash value registered in a block of a blockchain. Content data selected by a user from among pieces of content data that are management targets, is provided to a provision destination of the selected content data. Information on the provision destination of the selected content data is registered in a block of the blockchain in association with an identification number for identifying the selected content data. When the management system receives content data that is a target of authenticity determination, an identification number for identifying the content data, and user information of the content data, authenticity of the received content data is determined. In the determination of the authenticity of the received content data, the received user information is compared with the provision destination information registered in the blockchain.

  • Publication number: 20230373807
    Abstract: A YAG sintered body has a predetermined surface where intragranular pores are exposed. On the predetermined surface, arithmetic average roughness Ra satisfies Ra?0.5 ?m, and a ratio between maximum height Rz and maximum valley depth Rv satisfies Rv/Rz?0.7. With this configuration, the predetermined surface of a processed surface is smoothed to have improved plasma resistance and exhibit a particle-suppressing effect.

  • Patent number: 10880955
    Abstract: A ceramic member includes a voltage supply rod capable of reducing a local temperature drop of the ceramic member. The ceramic member comprises a ceramic base, a metal body disposed inside the ceramic base, and a voltage supply rod made of an electrically conductive material and having a far end portion electrically connected to the metal body. The far end portion is located at an end of the voltage supply rod in a longitudinal direction. The voltage supply rod also includes a heat-transfer reducing portion continuous with the far end portion. The heat-transfer reducing portion has thermal conductivity k2 and a cross-sectional area A2 in a cross section taken perpendicularly to the longitudinal direction. The thermal conductivity k2 and the cross-sectional area A2 satisfy a formula k2·A2<k1·A1, where k1 denotes thermal conductivity of the base end portion, and A1 denotes a cross-sectional area of the base end portion.

  • Patent number: 10849221
    Abstract: An electrode embedded member includes a plate-shaped substrate made of a ceramic; an inner electrode embedded in the substrate; a terminal disposed at a position that overlaps the inner electrode in a thickness direction of the substrate and is farther than the inner electrode from the front surface of the substrate; an intermediate insulator embedded in the substrate between the inner electrode and the terminal and that is made of a ceramic; and a connection electrode disposed along an outer surface of the intermediate insulator and that connects the terminal and the inner electrode. When seen in the thickness direction of the substrate, a cutout portion is formed in the connection electrode located at least outside an overlapping region where the terminal and the connection electrode overlap. The substrate and/or the intermediate insulator penetrates the cutout portion, and thereby the substrate and the intermediate insulator are integrated with each other.
