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.

摘要： A vibratory gyroscope including a planar elastic vibrator having vibrator piezoelectric material layers formed on both the front and back sides. The vibrator includes a base portion and three parallel elastic pieces extending from the base portion such that the a center elastic piece is located between two side elastic pieces. Electrode layers are formed over the piezoelectric material layers which cause both the side elastic pieces and the center elastic piece to vibrate in a plane, such that the vibrations of the center elastic piece are 180.degree. out-of-phase with the side elastic pieces. When the thus-vibrated vibrator is rotated, the elastic pieces are vibrated in directions parallel to the plane due to the Coriolis force. These deformations are detected as voltage changes across the piezoelectric material layers, and the voltage changes are used to determinate the angular velocity of the vibrator. The outside edges of the side elastic pieces are offset from an outer edge of the base section to prevent twisting stress, thereby allowing more precise vibration detection.
摘要翻译：一种振动陀螺仪，包括在前后两侧形成有振动压电材料层的平面弹性振动器。振动器包括基部和从基部延伸的三个平行的弹性片，使得中心弹性片位于两个侧面弹性片之间。电极层形成在压电材料层上，使得侧面弹性片和中心弹性片在平面中振动，使得中心弹性片的振动与侧面弹性片180度异相。当如此振动的振动器旋转时，由于科里奥利力，弹性片在与平面平行的方向上振动。这些变形被检测为跨越压电材料层的电压变化，并且使用电压变化来确定振动器的角速度。侧面弹性片的外边缘从基部的外缘偏移以防止扭转应力，从而允许更精确的振动检测。

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
