  • Patent number: 10307848
    Abstract: An electrical discharge machining electrode wire includes a core including a copper or a copper alloy, and a covering layer covering a periphery of the core and including a zinc. The covering layer includes an inner layer including a ?-phase of copper-zinc based alloy and covering the periphery of the core, and an outer layer including an ?-phase of copper-zinc based alloy and covering a periphery of the inner layer. An x-ray diffraction intensity of (0001) of the ?-phase is more than twice an x-ray diffraction intensity of (332) of the ?-phase.

  • Patent number: 10201318
    Abstract: In a test for supporting diagnosis of periodontal disease, a test method, whose measurement result has reproducibility and can be an objective index, is achieved and the loss of a tooth is predicted by use of the obtained objective index. A periodontal disease diagnosis supporting device supports diagnosis of periodontal disease by use of a captured three-dimensional image of a tooth part. The device includes a tooth root adhesion degree measuring part for measuring a degree of adhesion between a tooth root and alveolar bone by use of the image. The device further includes a periodontal disease diagnosis supporting part for supporting diagnosis of periodontal disease by use of a measurement result of the measuring part.
