摘要： PURPOSE:To simplify and miniaturize the constitution of a vibrating gyro. CONSTITUTION:A pair of two vibrating pieces 14, 16 are projected from a base section 12 and provided in a vibrating gyro 10 made of a light alloy such as duralumin. Only piezoelectric elements 20 for exciting the vibrating piece 14 along an X axis are mounted at the root of the vibrating piece 14 on both side faces of the vibrating piece 14. The vibrations of the vibrating piece 14 along the X axis are propagated to the vibrating piece 16, and the vibrating piece 16 is brought previously under the state of vibrations along the X axis. On the other hand, only piezoelectric elements 24 detecting the state of vibrations at a time when the vibrating piece 16 is vibrated along a Y axis are installed at the root of the vibrating piece 16 on the upper and lower surfaces of the vibrating piece 16. When the vibrating piece 16 receives Coriolis force based on rotational angular velocity omega in the periphery of a Z axis and the vibrating piece 16 is vibrated along the Y axis, the state of vibrations along the Y axis is acquired as an electric signal (AC voltage) by the piezoelectric effect of the piezoelectric elements 24.

摘要： PROBLEM TO BE SOLVED: To accurately detect angular velocity by eliminating influence of leaking vibrations. SOLUTION: Vibratory pieces 12-15 are excited to the left and right about the paper surface -(A)-, and when an angular velocity acts on supporting pieces 16, 17 round their axes the angular velocity is sensed from the vibrations (B) of the vibratory pieces 14 and 15 generated by Corioli's force wherein the vibration is of opposite phases to the left and right as directed perpendicularly to the paper surface. The leaking vibrations of the vibratory pieces 12-15 due to excitation are concentrated to the vibration mode of the same phase by resonating the vibration mode where all pieces 12-15 vibrate in the same phase to the excitation. Differential signals to represent the vibrations of the pieces 14 and 15 are taken out to lead to mutually setting off of the electric signals representing the leaking vibrations of the pieces 14 and 15, which should yield large electric signals representing vibrations of the pieces 14 and 15 related to the angular velocity.

摘要： PURPOSE:To obtain an angular sensor which achieves easier production and higher detection sensitivity. CONSTITUTION:A sensor element 10 of the angular velocity sensor is made up of multiple pairs of vibrators 22-27 for excitation differing in length sequentially and fixed in the thickness and width thereof and pairs of vibrators 42-47 for detection and piezo-electric elements 32-37 for excitation are bonded securely on the sides of the vibrators 22-27 for excitation while the piezo-electric elements 52-57 for detection on the sides turned by 90 deg. of the vibrators 42-47 for detection. AC voltage is applied to the piezo-electric elements for excitation of a pair of the vibrators for excitation to be vibrated steadily and when a specified rotational angular velocity is applied, a coriolis force works on the vibrator for detection to generate an electrical signal (AC voltage) by piezo-electric effect of the piezo-electric elements for detection. A combination to generate an electrical signal giving the maximum voltage is selected from the combinations of a pair of the vibrators for excitation to be vibrated and a pair of the vibrators for detection to detect and an excitation circuit and a detection circuit are connected to the vibrators selected. Thereby, a highly sensitive angular velocity sensor can be obtained even if production errors occur in the sensor element 10.

摘要： PROBLEM TO BE SOLVED: To excellently detect angular velocity by increasing amplitude of vibration of the Y axis direction of a vibration piece for detection. SOLUTION: Of first to fourth vibration parts constituted into an H type, the first and second vibration parts are composed of each vibration piece 11 to 13 and each vibration piece 14 to 16 and the third and fourth vibration parts are composed of vibration pieces 17, 18. When angular velocity around a Z axis is added when the vibration pieces 11 to 16 vibrate in an X axis direction, vibration energy of a Y axis direction due to Coriolis force proportional to angular velocity is excellently imparted to the vibration pieces 11 to 16 because the first and second vibration parts are divided into the vibration pieces 11 to 13 and the vibration pieces 14 to 16, respectively. Because vibration energy imparted to the vibration pieces 11 to 16 is transmitted to each of the vibration pieces 17, 18 and total mass of the vibration pieces 17, 18 is smaller than total mass of the first and second vibration parts, the vibration pieces 17, 18 vibrate at amplitude which is large in the Y axis direction.

摘要： PROBLEM TO BE SOLVED: To obtain an angular velocity sensor which eliminates an influence due to a leakage vibration, by which an angular velocity can be detected with good accuracy and by which every resonance frequency can be regulated simply. SOLUTION: Piezoelectric elements 21, 22 for excitation are attached to, and mounted on, outside faces of vibrating pieces 11, 14 in diagonal positions out of four vibrating pieces 11 to 14 which are constituted to be an H-shape, and the vibrating pieces 11 to 14 are excited to the X-axis direction, Piezoelectric elements 23, 24 for vibration detection are attached to, and mounted on, front faces of the vibrating pieces 12, 13 in other diagonal positions, vibrations in the Y-axis direction are detected, and respective vibrations caused by the Coriolis force are detected, respectively. A differential amplifier 43 fetches the difference between electric signals expressing the respective vibrations detected by the piezoelectric elements 23, 24, and the difference is output. Thereby, it is possible to simply regulate that a leakage vibration is generated in a direction identical to the Coriolis force at the vibrating piece on one side out of the vibrating pieces 12, 13 and that a leakage vibration is generated in a direction opposite to the Coriolis force at the vibrating piece on the other side, the leakage vibrations are offset simply, and an angular velocity can be detected with good accuracy.

摘要： PURPOSE:To reduce the manhour and to improve the quality for the circuits of electrodes, etc., which are formed on both sides of a light transmissive substrate of quartz, etc. CONSTITUTION:When the electrodes are formed on both sides of a vibrating gyro made of a quartz crystal substrate, a chromium thin film 102 and a gold thin film 104 are formed by vapor deposition on both sides of each vibrating piece. Then both sides of the vibrating pieces are irradiated by the YAG laser beams through the upper surface side of the vibrating gyro after the beams are focused by a lens. At the same time, the laser focal point (f) is set at the middle points of both sides of both vibrating pieces 86 and 92 respectively. Therefore both films 102 and 104 are fused and evaporated only at the part irradiated by the YAG laser beam on the upper surface side of each vibrating piece and at the beam incident side. Furthermore both films 102 and 104 are also fused and evaporated only at the part where the laser beam is emitted on the lower surface side of each vibrating pieces and at the beam emitting side.

摘要： PURPOSE:To improve the discrimination accuracy for the generation of a crack by discriminating whether a point shown by a natural frequency and an output level of a wave type of its natural frequency is within a prescribed area of a two-dimensional plane consisting of the frequency and the output level or not. CONSTITUTION:A percussion is given to an article to be inspected 1 by a steel ball 3, and its vibration is detected by an electromagnetic pick 5, amplified by an amplifier 7 and outputted to a frequency analyzer 9. The frequency analyzer 9 inputs a vibration waveform, based on a timing signal outputted from a delay device, and analyzes a frequency component of a frequency waveform and its output level. Subsequently, whether a point shown by a natural frequency of the frequency waveform and its output level is in a prescribed closed area which is set at every natural oscillation by a setting device 11, of a two-dimensional plane in which the frequency and the output level are parameters or not is discriminated by a discriminator 10. In such a way, the discrimination accuracy for the generation of a crack can be improved.
