    摘要: A turn-off feedback unit (23OFF) of a semiconductor device driving unit generates a feedback voltage as part of a voltage of a drive signal for establishing electrical continuity or disconnection in a bus according to a temporal variation of a collector current of a first semiconductor device (11U) when the first semiconductor device (11U) is turned off from on. A turn-on feedback unit (23ON) generates the feedback voltage according to a commutation current flowing through a free wheeling diode (12D) connected to a second semiconductor device (11D) when the first semiconductor device (11U) is turned on from off.

    摘要: To implement a piezoelectric actuator which can actuate a large object, such as an imaging element, in a predetermined direction at high power without involvement of rotational displacement; which can ensure a large amount of actuation; which is suitable for miniaturization and weight reduction; and which is advantageous in terms of mechanical durability and manufacturing cost.A piezoelectric actuator having a well-balanced mechanical structure is obtained by means of stacking a plurality of cross units, in each of which a pair of bimorph piezoelectric elements (21a and 21b, 21c and 21d) are crossed in the form of the letter X, into two layers (an even number of layers), and fixing the thus-stacked cross units. An imaging element 11 is stably supported by means of two movable ends (C-1, C-2) provided at the extremity of the piezoelectric actuator.
