摘要:
This invention relates to a fiber-made surface fastener comprising joining faces each in which a plurality of fiber-made engaging elements are provided on one surface of each flat base fabric. By specifying a structure and composition yarns of the base fabric of the same surface fastener, the ratio (A/B) of an area A of a range in which sound spectrum of a peeling-off sound Fourier-transformed in a range of 100 Hz to 15000 Hz is 100 Hz to 3000 Hz to an area B of a range in which sound spectrum of a peeling-off sound Fourier-transformed in a range of 100 Hz to 15000 Hz is 3000 Hz to 15000 Hz is 0.4 or more. Consequently, tone of a sound generated when the surface fastener is peeled off and when the surface fastener attached on a product is peeled off is shifted to a low tone side so as to reduce an uncomfortable sound to a lower tone thereby reducing a feeling of discomfort.

A functional device, a manufacturing method thereof, functional system and functional material are provided. A functional device is formed by coupling a first structure formed by local interaction and a second structure formed according to a predetermined global rule via a third structure having an anisotropic configuration. The third structure may be made by stacking two superlattice thin pieces, each split from a one-dimensional superlattice in form of a periodical lamination of conductive layers and dielectric layers, by rotating one from the other by 90 degrees.

A method and a system wherein IC card information can be changed in either of two ways is provided. The information stored in an IC card can be changed independently of the information that a center facility maintains, and then the corresponding IC card information maintained by the center facility is updated to reflect the changes made in the IC card. Alternatively, the IC card information maintained in the center facility is changed, and then the corresponding information in the IC card is updated to reflect those changes.

摘要:
A method and system for managing the overall life cycle of a product from its manufacture to its destruction or recycling. To the product is affixed a storage medium storing a product identifier uniquely identifying the product and information about the parts that are contained in the product. At each site that the product passes through during its life cycle, product life cycle information is recorded in the storage medium affixed to the product. When the product is to be destroyed or recycled, the information stored in the recording medium is used to determine the method for destroying or recycling. The product is then destroyed or recycled according to this method.
