Abstract: A parallel driving device that drives parallel-connected semiconductor elements includes a control unit and a gate driving circuit. The control unit detects a temperature difference between the semiconductor elements on the basis of detected values by temperature sensors that detect temperatures of the individual semiconductor elements. The control unit generates a control signal for changing the timing at which to turn on a first semiconductor element specified from the semiconductor elements on the basis of the temperature difference. The gate driving circuit generates a first driving signal for driving the semiconductor elements, and generates a second driving signal that is the first driving signal delayed on the basis of the control signal, and applies the second driving signal to the first semiconductor element.

Abstract: The efficiency of development of an application program constructed of a plurality of application windows utilizing GUI controls is improved. By causing a GUI control property defining information selector to select GUI control property defining information defined by a GUI control property defining information definer, the selected GUI control property defining information is reflected upon the property of a GUI control used in an application window editor. When the GUI control property defining information is changed by the GUI control property defining information definer, GUI control information in synchronism with the changed GUI control property defining information is searched from GUI control information used in the application window editor and GUI control property defining information after changing is reflected upon the searched GUI control property information.
