Abstract: A model for an application program is displayed. The model includes an input interface, an output interface, and a plurality of variables. Addition of a new variable and placement of an annotation on the display unit for the new variable is detected. The annotation identifies the new variable as an individually definable object or an identification key. The identification key identifies an individual situation and the individually definable object copes with the individual situation. A new model with a new input interface and a new output interface is generated based, at least in part, on the annotation identifying the new variable as an individually definable object or an identification key.

Abstract: To provide a driver for driving piezoelectric actuators with drastically reduced drive currents during on/off switch control, thereby reducing the power consumption of an overall device. Each of the plural piezoelectric actuators 1a to 1h is composed of a plate and piezoelectric sheets attached to the opposed surfaces of the plate. A positive feeder line 19 or a negative feeder line 21 is connected to the opposite side of each piezoelectric sheet to the side attached to the plate. The controller 27 on-controls the piezoelectric sheets of each of the piezoelectric actuators 1a to 1h by selectively applying a positive or negative drive voltage thereto. Thereafter, the controller 27 turns off the drive voltage applied to the piezoelectric sheets subjected to on-control and simultaneously with this, turns on a drive voltage to the piezoelectric sheets of any other one the piezoelectric electric actuators 1a to 1h to be driven next.
