The object of the present invention is to provide a fiber sheet having good fire resistant property, an expanded synthetic resin sheet having good fire resistant property and a molded article thereof, and a fire resistant acoustic material for cars, which uses the molded article. To attain the object, in the present invention, fire retardant capsules are adhered to the fiber sheet or the expanded synthetic resin sheet to provide a porous fire resistant sheet. When the fire retardant capsules are exposed to a high temperature, the synthetic film covering the fire retardant may break, exposing fire retardant, and giving fiber sheet or expanded synthetic resin sheet self extinguishing property. A molded article of the porous fire resistant sheet also has a good fire resistant property, and does not inhibit the ventilation property of the fiber sheet and the synthetic resin sheet, making said molded article useful as a fire resistant acoustic material for cars or buildings.
摘要:
An image coding apparatus is provided which satisfies various levels of demands on image distribution, both from image providers and from users. The image coding apparatus includes a coding block which codes predetermined image data. A separation unit separates the coded image data into basic data for reproducing contents of the coded image data as a visible image, and complementary data for complementing the basic data, so that the two pieces of data are distributed on different occasions. An adding unit adds information for independent copyright control to at least either one of the basic data and the complementary data.

A system includes servers accessing storage through a storage area network. The storage has a plurality of ports which may differ in data transfer speed, and memory resources connected to these ports. Data transmission between a port and a server is monitored. If the amount of data transfer exceeds prescribed limits, then a different port is selected, and that port is used for further communications.
