An ultrasonic probe of a radial scan type mountable on an ultrasonic observation apparatus, which inputs and outputs M numbers of signals in parallel, comprises the following: N (N>M) numbers of ultrasonic transducers disposed on an outer periphery of a tip, and grouped into plural sensor element groups activated in sequence, each of which has M numbers of ultrasonic transducers; N numbers of first signal lines respectively connected to the N numbers of ultrasonic transducers for transmitting a drive signal for driving the ultrasonic transducers and an echo signal from within a living organism; M numbers of second signal lines connected to the ultrasonic observation apparatus; and a multiplexer disposed between the first signal lines and the second signal lines, which selectively switches M numbers of the first signal lines for respectively connecting to the second signal lines according to the sensor element group to be activated.

There is provided a plasma display apparatus which scans the scan electrodes (Y) with at least one scan type among a plurality of scan types and a driving method thereof. Therefore, it is possible to prevent an excessive displacement current and thus protecting a data driver integrated circuit from electrical damage, by scanning the scan electrodes (Y) with at least one scan type among the plurality of scan types. The plasma display apparatus comprises a plurality of scan electrodes; a plurality of sustain electrodes formed in parallel to the scan electrodes; data electrodes intersecting the scan electrodes and the sustain electrodes; a scan driver scanning scan electrodes with one scan type among a plurality of scan types having different scan orders which scan the plurality of scan electrodes in an address period; a data driver supplying data to the data electrodes corresponding to the one scan type; and a sustain driver supplying a first sustain bios voltage that is less than a second sustain bios voltage supplied to the sustain electrodes in the address period from a setdown period of a reset period before the address period to a period before a first scan pulse is supplied to the scan electrodes.
