Abstract: A display unit displays a display screen including information on injection molding, and the display screen displays a setting screen portion that displays setting contents of the injection molding and a power screen portion that displays information on power consumption of the injection molding based on the setting contents together.

Abstract: A display unit displays a display screen including information on injection molding, and the display screen displays an actual result information display field that displays actual result information on power consumption measured at a time of performing the injection molding and a comparative information display field that displays comparative information on power consumption of the injection molding to be compared with the actual result information on the power consumption in the same display form as a display form of the actual result information display field together.

Abstract: A display device that guides monitoring items or operations required for protection of functions important for safety when an accident occurs is provided. The display device displays states of functions important for safety in a plant after accident occurrence in order of priority of the functions, and displays a value of a monitoring parameter for determining the state of the function, displays the monitoring parameter in a warning aspect when the value of the monitoring parameter deviates from a normal range, displays operations required for returning of the value of the monitoring parameter to the normal range in descending order of priority, and presents whether or not the operation can be executed.

Abstract: A communication relay system is connected to a line switched mobile communication system adapted to accommodate therein mobile terminals through radio channels and a packet switched mobile communication system adapted to accommodate therein the mobile terminals through radio channels. When a connection request has been made to a portable terminal, the communication relay system judges whether the portable terminal of interest is connected either to the line switched mobile communication system or to the packet switched mobile communication system.
