Abstract: A tire containing a tube capable of utilizing a sealant for automatically repairing a damaged portion of a tube pierced with a nail or the like in the radial or the transverse direction and for preventing an air valve, pressure gauge or the like form being blocked with the sealant. Right and left side walls and an outer peripheral wall of the tube contained within the tire are composed of an enclosed bag-like portion. Sealant is sealed in the bag-like portion.

Abstract: The viscosity of a puncture-preventing sealant (7) is set in a range of 25 to 35 dPa·s, and a thixotropy index is set in a range of 6.5 to 11.0, the sealant (7) being filled in a sealant chamber (6) defined to extend along an outer periphery of an air chamber (5) in a tire (T). When the tire (T) is being rotated by traveling of a vehicle, the viscosity of the sealant (7) is reduced by a stirring action provided by a vibration or a centrifugal force of the sealant (7), whereby the sealant (7) can be diffused uniformly in the sealant chamber (6). When the vehicle has been stopped and the stirring action has been extinguished, the viscosity of the sealant (7) is increased, whereby the sealant (7) is maintained in a state in which it has been diffused uniformly in the sealant chamber (6) without flowing downwards in the sealant chamber (6) by gravitation. Therefore, even when the vehicle is travelling at a high speed, the generation of a vibration and a noise can be prevented.

Abstract: A product management system has a database, an owner identification device, a card issuance device, and a checking device. The database correlates and stores therein product and owner information in relation to the owner of the product. The owner identification device wirelessly reads out information from an IC tag, which is fixed to the product and has stored therein product information, and also reads out from the database product information and correlated owner information. The card issuance device issues a card having a storage medium for storing the information. The checking device checks and compares information read out from the card, information read out from the IC tag, and information read out from the database, to thus validating the owner of the product. The product management system prevents a product which has been sold from being illegally used by or dealt with a person other than a valid owner.

Abstract: A mounting structure for a tire pressure sensing system. The tire pressure sensing system includes a pressure sensor placed on a wheel to sense pressure of a tire which is mounted on the wheel. The wheel is a cast wheel for a vehicle including a rim portion where the tire is mounted, a hub portion provided at the center of the rim portion, and spoke portions connecting the rim portion and the hub portion. The pressure sensor is placed in a boundary portion between the rim portion and the spoke portions. Since the pressure sensor is placed in the boundary portion between the rim portion and the spoke portions, a portion protruding into the tire when replacing a tire can be reduced. Consequently, workability for tire replacement can be improved.

Abstract: A commodity management system can manage information on commodities and commodity owners from sale times to disposal times and can identify a new owner in a disposal/recycling procedure. In an IC tag embedded in a motorcycle, management information associating the motorcycle and its owner is stored. A management card for recording the same management information is issued to a purchaser of the motorcycle. When the motorcycle is disposed and recycled, the dealer transmits a request for authentication of the owner to a management server. The management server then allows a disposal/recording procedure only if the management information stored in the IC tag embedded in the motorcycle matches the management information recorded in the management card.

Abstract: In a sealant-containing tire, an outer liner is fastened to an inner surface of a tread of a tire body, and a sealant chamber that is filled with sealant is defined between the outer liner and the inner liner, with an air chamber filled with air also being defined within the inner liner. By making the inner liner of flexible rubber of a 300% modulus of 60 kgf/cm2 or less, not only is a puncture in the inner liner caused by a nail made smaller, but the puncture is rapidly made smaller after withdrawal of the nail so that the flowing out of air from the air chamber is delayed. The flexible inner liner can easily be deformed by the air pressure within the air chamber and the sealant within the sealant chamber is therefore rapidly pushed into a puncture of the tread by the air pressure, thereby effectively repairing the puncture.
