Title: Portable information terminal device
Inventor: OTAKE HIROYUKI
IPC: H04W92/08
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To realize a portable information terminal device which can simply and efficiently increase memory capacity and also does not hinder portability. SOLUTION: This portable information terminal device 10 can mount a recording medium 23, such as a memory card via an interface 18 for memory extension freely insatiably and extractably, in addition to an internal memory 17 in which data received by a radio transmitting and receiving part 12 is stored. Because the medium 23 is itself a memory, it does not increase weight nor impair portability, in comparison with being connected with another information terminal and sharing the memory. For instance, when the medium 23 side receives data, its internal data is transferred to the memory 17, and subsequently a receiving operation is performed. After the reception, the previously stored data is returned to the medium 23 from the memory 17 within the range of free capacity. Naturally, data overwriting can also be designated.

Title: Path multiplexing system and method, and computer- readable recording medium recorded with program for executing the method
Inventor: YAMAMOTO MASAO
IPC: H04L12/28
Filed: 1999-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable memory environment where dispersion in path selection caused in the case of installing a plurality of routers to a network system in preparation for a system fault due to a machine trouble or a network fault and a path switching time is quickened on the occurrence of fault. SOLUTION: In this path multiplexing system, a plurality of routers 1-3 that conduct dynamic routing employing an RP protocol are installed between the same networks NW1 and NW2. Different path metric values of path information announced to public are set to a plurality of the routers to set the path priority so that a plurality of the routers place priority of the path respectively to each other. Furthermore, on the occurrence of a fault, a router detecting a fault of its own system increases its metric value to decrease the priority of the path and a router detecting a fault of the other systems decreases its metric value to increase the priority of the path so as to switch the priority of each network path M.
