Abstract: The present invention provides a monitoring method for infectious diseases. The monitoring method includes: obtaining disease information from a plurality of medical facilities 131, 132, 133, and 134; determining the disease occurrence status for each medical facility based on the disease information and a first criterion related to the disease occurrence status at the medical facility; and generating first area alarm information related to the infectious disease status in a first zone based on the disease occurrence status in the medical facilities associated with the first zone divided by a first area division, and a second criterion related to the disease occurrence status in the first zone.

Abstract: A method for decontaminating the nickel-based alloy includes oxidization of an oxide film accumulating radioactive nuclides with a first oxidizing agent to elute nickel into a solvent and thus to transform into a low-nickel film (S13 to S15). Elution amounts of Nickel, Chromium, and iron in the solvent are measured in the step S15 of the first oxidation step. Based on the elution amount, a second oxidizing agent is selected in the step S16. With the second oxidizing agent, the low-nickel film is oxidized to elute Chromium and thus to transform into an iron-concentrated film (S17 to S19). The iron-concentrated film is reduced with a reducing agent after the second oxidizing step including the steps of S13 to S19 to be dissolved and thus to be removed (S22).

Abstract: An electromagnetic clutch includes a first rotation transmission portion, annular field core, rotation stop member, second rotation transmission portion, armature, and spring member. The annular field core is supported by the first rotation transmission portion via a first bearing. The first bearing is housed in a hollow portion of the field core and fitted on an inner circumferential surface of the field core. The rotation stop member includes a flat portion which is fixed to an end of the field core on a side opposite to the armature. The flat portion is formed integrally with a retaining piece which projects toward the hollow portion of the field core and faces the first bearing when viewed from the axial direction of the field core.
