Abstract: When a mobile terminal obtains a container upon movement of a display range, a processor increases points in a storage unit. When the mobile terminal opens a container obtained by movement of the display range or as a present from another mobile terminal, the processor opens the container at predetermined success percentages, and writes an item obtained from the opened container in the storage unit. When the mobile terminal presents a container without opening it, the processor transmits screen data indicating a present to the other mobile terminal. The processor converts an item in the storage unit into points to increase the points in the storage unit based on an operation of the user of the mobile terminal.

Abstract: A gas-insulated apparatus is equipped with multiple sensors for sensing a partial discharge signal caused by a foreign substance, and a frequency analyzing section for analyzing the frequency of the sensed partial discharge signal. A defect type judging section estimates the defect type of the foreign substance from the signal obtained through the frequency analysis or from the voltage phase distribution of partial discharge synchronized with the frequency of the voltage applied to the gas-insulated apparatus, and a location determining section estimates the defect location and signal intensity from the multiple partial discharge signals. A defect size calculating section estimates the defect size for each defect type from the signal intensity and field distribution at the defect location. Dielectric breakdown risk evaluation is performed based on the defect size and type, and the insulation failure risk is diagnosed from the partial discharge.
