摘要： An angular velocity sensor for accurately detecting an angular velocity signal. The angular velocity sensor employs a tuning fork structure wherein first and second U-shaped piezoelectric members (4) and (5) superposed with each other through a detection electrode (6) are polarized in the same direction as the direction of thickness in which their prongs (4a) and (5a) at least on one sidre is superposed, and driving signals having opposite phases are supplied between driving electrodes (7) and (12) and between (8) and (11) disposed on the diagonal lines of the tuning fork prongs. Therefore, the driving signals are cancelled in the proximity of the detection electrode, and the driving signals do not mix in the signal detected by the detection electrode (6). Accordingly, the performance of the angular velocity signal can be improved.

摘要： An angular velocity sensor used for posture control of a moving body or for a navigation system, which is directed to accomplish higher sensitivity, lower offset, lower offset drift, low sensitivity to translational acceleration, and higher impact resistance by a smaller size and a lower cost. The sensor is made of a ceramic piezoelectric material or a quartz material and has four parallel vibration arms (12 to 15 or 112 to 115), support portions (11, 111) for commonly supporting one or both ends of these vibration arms, wherein the joint position with support portions (11 and 111), of the two inside vibration arms and that of the two outside vibration arms may be coincident or different, and the two outside vibration arms (12 and 15 or 112 and 115) of a comb-shaped composite tuning-fork (10 or 110) are used as the driving side tuning fork, while two inside vibration arms (13, 14 or 113, 114) are used as the detection side tuning-fork in such a manner as to correspond to driving and detection, respectively.

摘要： An integral bimorph angular rate sensor is formed by directly bonding two tuning fork members (1,2) in the thickness direction to enhance the detecting sensitivity of the angular velocity sensor. The individual tuning fork members (1,2) are formed from a single crystalline piezoelectric material such as quartz and are bonded in the crystal axis direction as to establish a piezoelectric phenomenon wherein the piezoelectric materials of the bonded tuning fork members have inverse polarities in their width or thickness directions.

摘要： TITLE OF THE INVENTION: Multi-Functional Sensor A multi-functional sensor capable of sensing the humidity and the concentration of reducing gases in the surrounding atmosphere with a single sensing element of p-type metal-oxide ceramic seimconductor is provided. When the ambient temperature is lower than 150.degree.C, the sensor can detect humidity in terms of variations in ion conduction due to the physical absorption of water by the sensing element, but when the ambient temperature or the temperature of the sensing element is at temperatures between 200 and 600.degree.C, the sensor can detect the presence or concentration of reducing gases in the surrounding atmosphere in terms of variations in electron conduction due to the chemical absorption of gases by the sensing element.

摘要： The present invention is related to an angular velocity sensor, and intends to improve the detection characteristic through a precise measuring of an angular velocity signal. For this objective, the invented angular velocity sensor comprises U-shape first and second piezoelectric elements(4),(5) bonded together sandwitching a detection electrode(6), wherein in at least one of the tuning fork arms(4a),(5a) the first and second piezoelectric elements(4),(5) are polarized in a direction of thickness along which the piezoelectric elements are bonded together. Driving electrodes(7),(12) and (8),(11) provided in diagonal arrangement on the tuning fork arm are supplied with driving signals inverse-phased to each other. In such a structure, the driving signals cancell to each other at the vicinity of detection electrode; as a result, the driving signals never mix with a detection signal to be detected by the detection electrode(6). Thus, the capability of detecting an angular velocity signal is improved.
