摘要： A pressure sensor 10 using a vibrator 11 as a pressure detection means is disclosed. The vibrator 11 includes a diaphragm valve 12. On both principal planes of the diaphragm valve 12, circular piezoelectric bodies 14a and 14b are formed respectively. On one principal plane of the piezoelectric body 14a, a first circular electrode 18a is formed. On one principal plane of the piezoelectric body 14a, a second hollow circular electrode 18b is formed outside the first electrode 18a. On one principal plane of the piezoelectric body 14b, a third circular electrode 20a is formed opposing to the first electrode 18a. On one principal plane of the piezoelectric body 14b, a fourth hollow circular electrode 20b is formed outside the third electrode 20a, opposing to the second electrode 18b. In the diaphragm valve 12, an inside circular portion 12a interposed between the first electrode 18a and the third electrode 20a and an outside circular portion 12b interposed between the second electrode 18b and the fourth electrode 20b vibrate radially in such a manner that they expand and contract in the reverse directions.

摘要： The vibrating gyroscope includes, for example, a regular triangular prism-shaped vibrating body. The vibrating body is formed with a material which generally generates mechanical vibration such as elinver, ceramics. The piezoelectric elements are respectively formed to the three sidefaces of the vibrating body. An oscillation circuit is connected between the two piezoelectric elements and the other piezoelectric element. Further, two U-shape supporting members made of metal wire are fixed to the ridge-line portions of the vicinity of the nodal points of the vibrating body. The both ends of the two supporting members are fixed to the rectangular-shaped supporting body. The supporting body has a cutting portion piercing through it from its one surface to the other or a groove portion as a suppressing means for suppressing the interference of vibrations between the fixing points of the ends of one supporting member and those of the other supporting member.
