Abstract: Provided are an abnormality detection system, an abnormality detection device, an abnormality detection method, a computer program, and a chain that enable detecting of an abnormality not only in a chain but also in equipment using the chain while distinguishing the location at which the abnormality occurs. The abnormality detecting system comprises a sensor unit comprising a sensor, to be fixed to a chain that is to be attached to equipment, and transmitting an output from the sensor, a detection section which detects an abnormality of the chain or the equipment based on the output, and a determining section which determines a location of the abnormality in the equipment, based on a position of a part fixed with the sensor unit in the equipment, the position changes in each time point with moving of the chain.

Abstract: An electronic toy has a head, a body and legs. A display that displays the expression of the eyes is provided to the front of the head, and a speaker and a detection switch that detects the pressing of such speaker are provided on the upper face of the head. A sound sensor and light sensors are housed inside a nose. Ears are rotatably provided on both sides of the head, and a lower jaw capable of being opened/closed is provided below the nose. A tail is provided to the rear of the body. A controller housed in the nose controls the posture, outcry, melody, expression of the eyes, etc. from the communication biorhythm and pet biorhythm prepared in accordance with the way a user contacts the toy through sensory input indicated with detection signals from the sound sensors, infrared sensors, feeding indications, light sensors, and the like.

Abstract: A floating toy is provided which can achieve varied and entertaining movements by means of a simple composition. The floating toy comprises: a liquid container section (11, 12) containing liquid therein; a figure (2) of lower specific gravity than the liquid, accommodated inside the liquid container section; magnetic bodies (31, 32) accommodated movably inside the liquid container section; line members (41, 42) extended between the figure and the magnetic bodies; and electromagnetic mechanisms (51, 52) that act on the magnetic bodies. The magnetic bodies and the figure are caused to move against the buoyancy force of the figure, by passing current through the electromagnetic mechanisms, and are caused to return to their original positions by the buoyancy force of the figure, by releasing the passage of current through the electromagnetic mechanisms.
