A writing implement is provided which is designed to draw lines using capillary action, wherein the width of the line can be freely adjusted while the line is being drawn and it is possible to draw lines of almost the same width at the beginning of the use of the writing implement as at the end of use. A felt-tip penis provided with an ink reservoir, a collector, and a corefor drawing by capillary action the ink that has been dispensed by the collector, dispensing the drawn ink from the tip, and adhering same to a paper surface. Even in repetitive writing, the rate of variability in the width of the lines drawn at the end of use with respect to the width of lines drawn at the beginning of use is 10% or less.

In a network, an inter-network connection unit is connected to perform transmission of data between the network and another network. The inter-network connection unit is furthermore connected to a multiplexer. Between the multiplexer and another multiplexer to which an inter-network unit installed in the other network is connected, data transmission is performed via a multiplex line. The multiplexer changes the communication capacity of a communication line connecting the inter-network connection unit to the multiplexer in accordance with the data transmission quantity between the multiplexer and the inter-network connection unit connected thereto and dynamically changes the communication band assigned to the inter-network connection unit in accordance with the change of the communication capacity.

Method for dynamically assigning communication bands

A multiprocessor information processing system has an additional function to detect a fault occurring in a processor. A counter is provided for each of a plurality of processors for holding an associated fault supervising code. The code stored in the associated counter is periodically updated by the associated processor while the update status of the code is supervised on a cycle longer than the cycle of the updating period. If a fault occurs in one of the processors, the fault supervising code corresponding to that processor will not be updated. Thus, the faulty processor can be detected by periodically supervising the update status of the fault supervising code. The supervising operation can be carried out by software or hardware.
