A parallel monitor circuit (1A) for monitoring one (C1) of serially connected plural capacitors (Cn) receiving a direct recharging current is disclosed. The circuit comprises a bypassing transistor (Q1) for bypassing the capacitor (C1) with the recharging current when the capacitor voltage (VSo1) exceeds a monitor voltage (Vr1) determined by a voltage setting circuit in order to equally recharge the capacitors. A transferring unit transfers a voltage control circuit (VS1) and an internal circuit connected to the voltage control circuit to a standby mode when the voltage control circuit receives a specific combination of voltage codes (RC1).

This invention can make data communications at an optimal transfer rate on the basis of the unarrived data volume on a network between two end terminals. For this purpose, a transmitting terminal (1-1) adds sequence number information to data generated by a data generator (1-11), and transmits the data to a receiving terminal (1-2) via a data transmitter (1-12). Since the receiving terminal (1-2) transmits data including the sequence number in the received data, the transmitting terminal determines that data (buffer capacity) corresponding to the difference between the current sequence number and the received sequence number remain on the network and calculates that volume using a network buffer data volume calculator (1-14) The transmitting terminal determines the transmission rate on the basis of the calculation result, and controls the data transmitter (1-12) to transfer data at that transmission rate.

An information acquiring apparatus acquires, when a travel object such as a traveler travels with transportation, passage time at which the travel object passes through each passage point at a departure/arrival facility, transportation specifying information indicating transportation, situation information indicating a situation and so forth. The travel process prediction apparatus stores the acquired information in an associated manner, and obtains a regression equation representing the relationship between items included in the transportation specifying information or situation information and passage time at a specific passage point, elapsed time while the travel object passes through two specific passage points or a result of comparison between the passage time and boarding completion time. The travel process prediction apparatus calculates a predicted value of future passage time, elapsed time or a result of comparison by substituting the content of the expected transportation specifying information or situation information for the regression equation.
