摘要： According to the invention, there is provided a stepping motor comprising a laminate type torsion actuator having a pair of cylindrical outer peripheries to be torsionally displaced relative to each other, a cylindrical fixed member surrounding said laminate type torsion actuator with certain space therebetween, first longitudinally vibrating elements placed between said fixed member and one of the cylindrical outer peripheries of said laminate type torsion actuator for selectively connecting or separating the fixed member and the torsion actuator through its elongation or contraction, second longitudinally vibrating elements placed between said fixed member and the other cylindrical peripheries of said torsion actuator with certain space therebetween for selectively connecting or separating the fixed member and the torsion actuator through its elongation or contraction with a phase inverse to that of the first elements. Such a stepping motor allows fine control of its rotary speed and position and large torque.

摘要： A clamp-on ultrasonic flowmeter has a pair of ultrasonic transmitting-receiving devices which are placed on a pipe in which a liquid flows. Each device is composed of a composite of a ultrasonic transducer and a ultrasonic propagating element which propagates ultrasonic wave transmitted by the transducer predominantly in the direction perpendicular to a plane of the transducer (which is arranged at an acute angle from the center line of the pipe), and a ultrasonic propagating layer placed between the ultrasonic propagating element and the pipe. The ultrasonic propagating layer has a viscosity of 0.5×10−3 to 3×10 Pa.sec at 25° C. and a rate of sonic propagation in terms of V1 at 25° C. satisfying the condition of 0.5

摘要： A vibratory gyroscope including an elongated vibrator having a central (neutral) axis (Y-axis), a drive unit for deforming the first direction such that the vibrator vibrates in a first (X) direction, an added mass attached to the vibrator at a position offset from the central axis in a second (Z) direction, and a detector formed on the vibrator. Rotation of the vibratory gyroscope about the second (Z) direction during vibration in the second direction causes Coriolis force to acting on the added mass in a direction parallel to the central axis. Because the added mass is offset from the central axis, a resulting vibration in the second (Z) direction is produced, which is detected by the detector. With this arrangement, the central axis of the vibrator is placed in parallel with the surface of rotation of the rotating system. Thus, rotations about two or three axes in each direction can be detected in such a manner that noise generation is prevented.
