Title: Method and program for increasing efficiency of file transfer
Inventor: DOI TOMONORI
IPC: G06F12/00
Filed: 2001-02-15
Abstract: PROBLEM TO BE SOLVED: To increase the efficiency of a file transfer in such a network environment as is used on a user level. SOLUTION: When a terminal requests the other terminal to transfer a file (S1), before transfer, a file transfer monitoring means at a transfer side determines whether or not a file depression means is installed in a terminal at a transferred side (S2 to S4). When the means determines that the depression means is installed in the transferred side, the file is compressed by a file compression means at the transferred side and transferred to the transferred side (S6 to S8).  When the means determines that the depression means is not installed in the transferred side, the file not compressed is transmitted to the transferred side (B1, 2), whereby, since the possibility of compression of the file at the transfer side can be determined without troubling an end user, the file can be transferred efficiently, and since the education of file transfer system must not be given to the end user by an administrator, loads on both the administrator and the end user can be reduced.

IPC: H04Q3/42
Filed: 2001-02-22
Abstract: PROBLEM TO BE SOLVED: To provide a line terminator that can prevent occurrence of noises due to a difference of current consumption between transmission and reception. SOLUTION: When a N(normal)/R(reverse) control section 105 turns a N/R switch 109 to a reverse state ('H'), the line terminator reaches communication state with a subscriber, when a transmission reception control section 104 brings a reception section 103 to an operating state ('H'), an 'L' output of a NAND circuit 110 turns on a transistor(TR) 111, that causes a current to flow via a variable resistor 112. Furthermore, the reception section 103 uses an AGC(automatic gain controller) switch 114 to select the resistance of the variable resistor 112, so that the difference from the current consumption between the transmission and reception states, depending on the resistance of a line before the communication with the subscriber.  Thus, smoothing of the difference from the current consumption between the transmission and reception states different from each line can prevent the occurrence of noises.
