Abstract: A first and a second charging circuit each having a diode and a capacitor are connected to a buffer. In the first charging circuit, an overshoot based on a reflected signal generated by an output signal is stored as an electric charge to the capacitor, and in the second charging circuit, an undershoot based on a reflected signal generated by an input signal is charged as an electric charge to the capacitor, whereby the energy of the overshoot and the like is recovered. These charges are collected in the charging circuit, stored in the capacitor, converted into a power supply voltage of an internal power supply by a stabilization circuit, and are supplied as an internal power supply. The reflected energy of the signal generated during signal transmission at the time of data transfer between semiconductor devices is stored, and the stored energy is used in driving the signals.

Abstract: In a battery exchange system for facilitating exchange at appropriate intervals of a chargeable battery with another fully charged chargeable battery for charging, a user device having characteristic identification information reads a serial number from a battery when the battery is installed and transmits to a control device correspondence information in which the identification information and the serial number have been placed in correspondence with each other. A charging device reads the serial number from a battery when charging of the battery has been completed and transmits the serial number to the control device. The control device calculates a scheduled charging time of the battery having the serial number that has been transmitted from the charging device based on the time of reception of the correspondence information that was transmitted from user device and, before the calculated scheduled charging time, carries out notification prompting battery exchange.
