摘要： A vibration-sensing gyro composed of a light alloy such as duralumin includes a base and a first pair of tines projecting parallel to each other from the base. Piezoelectric elements are mounted on the root of the side faces of the first pair of tines to excite the first pair of tines along an X axis. The vibrations of the first pair of tines along the X axis are then propagated to a second pair of tines to vibrate the second pair of tines along the X axis. Piezoelectric elements are mounted on the root of the upper and the lower faces of the second pair of tines to detect vibrations of the second pair of tines along an Y axis. When the second pair of tines receives the Coriolis force based on an angular velocity .omega. around a Z axis and vibrates along the Y axis, the vibrations along the Y axis are detected as electric signals (alternating current voltages) by piezoelectric effects of the piezoelectric elements.

摘要： A vibration-sensing device (10) with high sensitivity includes a torsion bar (16) fixed on both ends thereof to a frame, a tuning fork-shaped vibrating member (12) joined with and supported by the torsion bar (16), and first and second torsion vibrating bodies (14,15) symmetrically projected from the torsion bar (16). The torsion bar (16), the tuning fork-shaped vibrating member (12), and the torsion vibrating bodies (14,15) constitute a torsion vibrating system. The application of an angular velocity to the vibration-sensing device (10) under the condition of plane vibrations of first and second vibrating tines (12a, 12b) of the first tuning fork-shaped vibrating member (12) along an X axis generates Coriolis forces to drive torsion vibration of the first tuning fork-shaped vibrating member (12) round the torsion bar (16), thereby driving torsion vibration corresponding to the angular velocity in the torsion vibrating system. The torsion vibration is amplified by the first and second torsion vibrating bodies (14,15) and detected by torsion vibration-detecting piezoelectric elements (20a,20b) attached to the torsion vibrating bodies (14,15). An angular velocity sensor using the vibration-sensing device, and a method of adjusting the sensitivity of the device are also provided.

摘要： the present invention provides a force transducer having high compression fracture strength and high detection sensitivity, thus satisfying both detection precision and reliability, and also a method of fabricating such a force transducer. The force transducer is so constructed that a compression force is transferred via a pressure transfer block to narrow strain gages, which protrude from the surface of a silicon substrate and provide a small pressure-bearing area. Therefore, large compression strains act on the strain gages and thus the detection sensitivity is increased. When the compression force exceeds a predetermined value, the pressure transfer block comes into contact with the surface of the silicon crystal, thus improving the fracture strength of the strain gages. These narrow, protruding strain gages can be fabricated easily by a single mesa etching process.

摘要： A physical quantity detecting apparatus for detecting a physical quantity of an object of measurement. The position of movement of an object of measurement is divided into a given number of segments in advance. The output of a physical quantity sensor for detecting a physical quantity of the object of measurement is calculated on the basis of a correction operation expression which has an independent coefficient group for each segment so as to correct the offset component and the sensitivity. Thus, a physical quantity such as a transmitted torque is detected with high accuracy at real time without being influenced by the fluctuations of the offset output and the sensitivity depending on the position of rotation. The correction operation may also be performed using the temperature dependence function of the offset signal and the temperature dependence function of the sensitivity, thereby enabling the accurate measurement of the physical quantity without the influence of the temperature change.
