Abstract: Operations of nuclear power plants have been suspended in various locations due to the Great East Japan Earthquake. However, it is not necessarily essential to undertake strict emergency energy saving measures at all times.

Abstract: The conventional demand target display device based on time information differing from the information used by electric power companies and electric power consumers causes a divergence regarding their demand values. Therefore, a demand target display device with a dual-purpose scale, which acquires AC signals based on the AC waveform of AC power from a power supply line, generates time information based on the acquired AC signals, transmits the generated time information via radio waves within a housing, receives the transmitted time information via radio waves within the housing, indicates the time on the dual-purpose scale based on the received information, acquires electrical energy consumption within a segment for a given target demand value including the current time, and indicates the relationship between the acquired electrical energy consumption within a segment recorded and a target demand value set for such segment, is proposed.

Abstract: Conventional technology is based on the prerequisite that an appropriate value has been established in advance as a target value for power consumption, but this does not does not take into consideration the possibility of establishment of an excessively low value. In order to solve the aforementioned problem, an alarm output device is provided, characterized by determining at all times whether or not electric power expected to be consumed within a regular interval of time exceed the set upper limit target value and by outputting an alarm in case that the electric power exceeds the set upper limit target value at approximately the point in time at which a predetermined interval of time commences or by outputting instructions for changing the set upper limit target value within such interval.

Abstract: With conventional timepieces, information about target physical quantities, target achievement, and time has been indicated using separate displays, thereby making it difficult for users to instantly understand whether or not a target has been achieved.
