Abstract: The electric power loss at the time of charging/discharging storage batteries is reduced. An electric power system control device maintains a balance of power supply and demand of an electric power system by controlling charging/discharging of a storage battery, and includes a frequency detection unit; a frequency prediction unit which predicts the frequency from the frequency calculated by the frequency detection unit and history data of power generation/load supply-demand data. A charging/discharging amount determination unit sets a charging/discharging amount corresponding to a value lower or higher than the frequency of the electric power system predicted by the frequency prediction unit within a range not exceeding a lower or higher limit value of the frequency and determines the charging/discharging amount of the storage battery based on the value. And, a control command unit transmits a control command to the storage battery based on a result of the charging/discharging amount determination unit.

Abstract: According to the present invention, drive voltage pulses are applied between a pair of electrodes by driving a first power source having a specific voltage from a state in which the electrodes are maintained at the potential of a reference power source that is different from the potential of the ground power source, and then returning it to the reference power source. As a result, the gas discharge current or capacitance charging and discharging current accompanying the application of the drive voltage pulses is prevented from flowing to the first power source line. The above-mentioned gas discharge current or capacitance charging and discharging current resulting from the application of the drive voltage pulses flows to the first power source or the reference power source electrically separated from the ground power source, and does not flow to the ground power source line, so no noise is generated on the first power source.

According to one aspect of the invention, replacement decision is performed in order that a second replacement region can be made smaller than a first replacement and that the second replacement is given priority over the first replacement. Therefore, the first replacement can be controlled by a repair address of a small number of bits, thus making it possible to achieve a semiconductor device having a defect repair circuit with small area and high repair efficiency.

Abstract: A wavelength division multiplex communication system comprises a head station (2) and a plurality of terminal stations (1) interconnected by an optical fibre cable (3). The head station (2) transmits continuous wave modulated wavelengths (.lambda..sub.1 -.lambda..sub.k), and a signalling wavelength (.lambda..sub.0) which is used to indicate, in each time slot, which wavelengths in the following time slot are available for transmission. Each terminal station (1) is arranged to receive the signalling wavelength, to determine therefrom whether the next time slot contains any data packets for that terminal station and, if so, to receive the packets. The terminal station (1) is arranged, if it has a data packet to transmit, to determine from the signalling wavelength whether the next time slot already contains data packets for the destination station and, if so, to avoid data collision by not transmitting its own data packet. The terminal station (1) then determines a free wavelength (.lambda..sub.
