Abstract: An odor generation alarm and a method for informing an unusual situation having a high attention attracting effect and a high degree of safety are provided. An odor generation alarm includes an odorant receptacle, a drive section, a detector and a circuit section which is a controller. The odorant receptacle contains an odorant. A concentration of the odorant in air at which a person can no longer tolerate a strength of smell is lower than a no observed effect concentration of the odorant. The drive section causes the odorant to be emitted from the odorant receptacle. The detector detects occurrence of an unusual situation, and outputs a detection signal. When the detection signal from the detector is inputted, the controller causes the drive section to emit the odorant in accordance with the detection signal.

Abstract: [Problem] To provide a disease diagnostic system capable of diagnosing with high accuracy whether a subject is afflicted with a disease, without inflicting pain on the subject. [Means for Resolution] The disease diagnostic system includes collecting means (5) for collecting a substance (e.g., aspiration, sweat, human waste or urine) emitting an odor (e.g., mouth odor, body odor or underarm odor) and storing the same therein, measuring means (10) for measuring whether an indicated substance indicative of the existence of a disease is contained in the odor-emitting substance stored in the collecting means (5), and control means (20) for processing a signal indicative of a result of measurement by the measuring means (10) to determine whether the subject (2) is being afflicted with a disease.

Abstract: The present invention provides a clothes holding device which is easily assembled (formed) as a clothes holding device (for example, a hanger), which is compact, which has an interior function for use as an interior material. The device includes a plate member having flexibility, wherein the plate member is bent on the symmetrical axis, and clothes are held with a resulting bent portion. When clothes are not held, the clothes holding device of the present invention is assimilated with the surface of a wall, and appears to be a part of a room's interior. When holding clothes, a vertical-directional lower area of the plate member is bent along the horizontal axis, and the bent portion and the remaining portion hold clothes.

Abstract: An object of the present invention is to provide a card hard to counterfeit it by reading information stored thereinside even if an electronic technique is abused, a card reader used to read such a card, and an authentication system using the card and the card reader. Therefore, in the present invention, fragrant materials (fragrant material chips 13) are placed at predetermined locations on a card surface on the side of contact with the card reader (card reader 2), and the surface on which the fragrant materials are placed in such a manner that a predetermined amount of fragrant-material molecules pass therethrough and are released, is covered so as to reach a flat surface.
