Abstract: To provide a tire inner liner formed by using a cylindrical film (10) including a thermoplastic material and obtained by inflation molding, in which a ratio of breaking strength in a tire width direction (14) to breaking strength in a tire circumferential direction (18) of the cylindrical film (10) is from 1.35 to 1.80. A pneumatic tire (1) is obtained by extruding and molding the cylindrical film (10) in which a ratio of breaking strength in an extrusion direction (12) to breaking strength in a direction perpendicular to the extrusion direction (16) is from 1.35 to 1.80 by inflation molding using a thermoplastic material, forming a green tire by placing the obtained cylindrical film (10) on a forming drum so that the extrusion direction (12) becomes the tire width direction (14), and vulcanizing and molding the green tire.

Abstract: The present invention relates to a broadband transmission path modem, a radio terminal device, a program, and a storage medium. An object of the present invention is to provide a radio terminal device with various communication services including access to the Internet etc. via a broadband transmission path at a low cost without remarkably impairing the effects of cost-cutting, downsizing, lightening, and power economization. To this end, a broadband transmission path modem according to the present invention interfaces functions, defined in advance as a specification of a radio access link, of an entity realizing a communication protocol applied to the broadband transmission path and an entity realizing the radio access link, and converts transmission information delivered to realize an added function not defined in the specification.

Abstract: A DSL communication method and apparatus provides mutual communications between a user-site DSL modem and a provider-site router by using an existing two-wire telephone line and an existing DSL communication technology. In the DSL modem, a plurality of virtual channel values are correlated to a PPP connection between the modem and the router. Input IP data is received and the IP data is output according to a priority class defined for a sender IP data contained in the input IP data. An ATM cell is generated in which one of the plurality of virtual channel values corresponding to the sender IP data of the input IP data is assigned to the output IP data. The resulting ATM cell is transmitted from the modem to a DSL circuit connected to the router.

Abstract: An IP datagram transmission technique in an ATM network. A DSU 1 comprises a selecting unit selecting a type of distribution representing distribution of a packet having a transmission source address to either bridging or routing, a bridging processor bridging the packet to generate a packet when bridging is selected, a routing processor routing the packet to generate a packet when routing is selected, and an ATM terminating unit encapsulating the packet to generate an ATM cell, thereby automatically discriminating between bridging and routing. Accordingly, the user can simultaneously connect to a plurality of Internet service providers to receive different service modes.

Abstract: An IP data transmission technique on ATM. A bridge-hub apparatus comprises an input/output unit inputting/outputting a frame including a MAC address by which a terminal connected to a network can be identified, a upper identification data holding unit holding own IP address of the bridge-hub apparatus connected to the network, a lower identification data holding unit holding own MAC address of the bridge-hub apparatus connected to the network, and a lower layer frame processing unit transferring a frame to either own apparatus's side or other terminals' side connected to the network on the basis of own IP address and own MAC address, thereby switching at high speed.
