摘要： A signal transmit-receive device of the invention reduces the number of high-speed signal lines required for connecting a transmitting circuit group and a receiving circuit group, and for running a loopback test on a signal transmit-receive device. The loopback test circuit uses an error detecting circuit, a test signal producing circuit, and a wiring for transmitting error information. The error detecting circuit compares a test signal pattern defined in advance by a first communication device and a received signal pattern. The test signal producing circuit produces the test signal pattern based on error information. If an error is detected, the error signal is transmitted to the test signal producing circuit through the wiring. The test signal producing circuit produces a predetermined test signal pattern if the error signal DE has an L level; upon receiving H level, it sends back the predetermined test signal pattern to the first communication device.

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.

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.
