An absorbent article for wearing about the lower torso of a wearer includes a topsheet, a backsheet joined to at least a portion of the topsheet, and an absorbent core disposed between the topsheet and the backsheet. The absorbent core includes a first layer and a second layer, wherein the first layer is disposed in fluid communication with the second layer. The first layer has a first shape and the second layer has a second shape. The first shape is different from the second shape. Each of the first layer and second layer comprise less than about 20 percent airfelt.

A paint film-protecting sheet, which is unwound from a roll for use, and in which occurrence of adhesive transfer at edges thereof is effectively prevented, and a method of manufacturing same are provided. The paint film-protecting sheet is in the form of a roll obtained by winding in a lengthwise direction a pressure-sensitive adhesive sheet formed of a substrate in continuous sheet form and a pressure-sensitive adhesive layer disposed on the substrate. The substrate comprises a resin component made primarily of polyethylene resin or polypropylene resin. The paint film-protecting sheet, after being unwound from the roll, has a percent shrinkage, in the lengthwise direction, of not greater than 1.2% when heated at 80° C. for 1 hour.

A network system includes a switch device and a plurality of communication terminals. The switch device has a plurality of ports. The switch device receives a packet at its one port and transmits the packet from another port corresponding to the packet's destination. The communication terminals are connected to the ports of the switch device respectively to transmit and receive packets. The terminal transmits a connection request including connection destination information to the switch device and performs communication using unused signal lines when a “connection possible” notification is received from the switch device. Upon receiving the connection request, the switch device determines if connection to a port corresponding to the connection destination information is possible. If connection is possible, the switch device transmits a “connection possible” notification to the connection-request-making terminal and connects an unused signal line of the port connected to the terminal to a signal line of the port corresponding to the connection destination.
