Abstract: A damper is provided which can more reliably prevent malfunction and breakdown and which enables efficiently performing repair and inspection operations.

Abstract: Provided is a hinge that can prevent a defect, a failure, or the like with greater certainty, and enables inspection and repair work to be efficiently carried out. A hinge comprises a first wing member that is connected to a first connection object and a second wing member that is connected to a second connection object. The hinge rotatably connects the second connection object to the first connection object. The hinge comprises a sensor that detects a change inside the hinge or in a prescribed external environment change in the external environment detected by the sensor to the outside via a sensor that detects a prescribed component constituting an odor, a gas sensor that detects a prescribed gas, a dust sensor that detects the amount of dust, and a illumination sensor that detects brightness.

Abstract: A method and a device for remote monitoring supervisory information about maintenance of a hinge are provided that are capable of improving efficiency of periodical inspection and maintenance of a hinge and capable of preventing inconvenience and a trouble of the hinge in advance. A hinge 3 rotatably supports an opening and closing member 2 with a fixed member 1 of an instrument or the like. Supervisory information about maintenance of the hinge 3 is detected. The detected supervisory information is transmitted to a maintenance management server 7 via a communication network like the Internet 6. The maintenance management server 7 manages the maintenance of the hinge based on the supervisory information.
