摘要： An ultrasonic motor drive device capable of prolong the service life of an ultrasonic motor by preventing the motor from being unstably operated when the motor is driven at a lower speed of at least two speeds. When the ultrasonic motor (3) is driven at a rather low speed in normal driving, the motor can be prevented from being unstably operated by its driving at a rather low speed by driving the motor at a rather high speed for each specified interval. Thus, the service life of the ultrasonic motor can be increased.

摘要： In an ultrasonic probe including an element part 1 for transmitting and receiving ultrasonic waves, a relay cable 2 connected to the element part 1 and an oscillation mechanism part for oscillating the element part, a cross section of the relay cable 2, which is taken perpendicularly to a rotation axis 3 of the oscillation that is provided to the element part 1 by the oscillation mechanism part, has at least two arc-shaped parts smoothly connected each other, more specifically, S-shape arc-shaped parts or reversed S-shaped parts. In addition, the relay cable 2 is drawn from the surface of the element part 1 facing the rotation axis 3. In this manner, the stress applied to the relay cable 2 during the oscillation of the element part 1 can be dispersed, thereby improving durability of the relay cable 2.

摘要： Herein disclosed is an ultrasonic probe comprising a housing, a driven shaft rotatably supported by the housing, a transducer supported by the driven shaft to be swingable on one side of the driven shaft and operative to transduce an electric signal to and from an ultrasound, a drive shaft rotatably supported by the housing spaced apart from and in parallel relationship with the driven shaft in the predetermined direction; a drive motor supported on the housing and drivably connected to the drive shaft; and a drive belt passed on the driven shaft and the drive shaft to transmit the rotation from the drive motor to the transducer. The transducer has the ultrasound emitted therefrom and reflected thereto through the housing in a predetermined direction. The ultrasonic probe thus constructed makes it possible to reduce the rotation radius of the transducer independently of the size of the electric motor by spacing the rotation axes of the drive motor and the transducer in order to provide an ultrasonic probe smaller in size. The rotation of the drive motor transferred into the rotational motion of the transducer without causing a backlash prevents the accuracy of the ultrasonic probe from deteriorating.

摘要： An ultrasonic probe is provided which may be employed in medical applications to radiate an ultrasonic wave for inspecting the interior of a patient's body noninvasively. The ultrasonic probe includes a scan mechanism which consists of a rotating mechanism and a swinging mechanism. The rotating mechanism is designed to rotate a cylindrical holder having installed thereon a piezoelectric element which emits an ultrasonic wave and receives the echo. The swinging mechanism is designed to swing a rotary base which supports the rotating mechanism to swing the cylindrical holder about an axis of rotation extending perpendicular to that of the piezoelectric element.
