Abstract: A game device controls a game in which an action is applied to a movable object. A prediction accepting unit accepts a prediction made by a user on a movement parameter of the movable object when a predetermined operation of making a prediction is performed by the user. A moving unit decides the movement parameter of the movable object. A determination unit determines a result of the prediction made by the user based on movement parameters respectively predicted by the user and decided by the moving unit. A display control unit displays an arrival point area indicating an expected arrival position of the movable object in an active area in which the action can be applied to the movable object, and changes a size of the arrival point area based on a result of determination by the determination unit.

Abstract: A motor-driven compressor includes an electric motor, a drive circuit, a modulation method controller, a temperature measuring section, a high-temperature (HT) stop controller, and a high-temperature (HT) stop temperature setting section. The high-temperature (HT) stop controller stops the electric motor when the temperature measured by the temperature measuring section is higher than or equal to a predetermined high-temperature (HT) stop temperature. When the modulation method is the three-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a three-phase high-temperature (HT) stop temperature. When the modulation method is the two-phase modulation, the HT stop temperature setting section sets the HT stop temperature to a two-phase high-temperature (HT) stop temperature, which is higher than the three-phase HT stop temperature.
