    摘要: A diaphragm structure includes a ceramic substrate having at least one window portion and a thin diaphragm laminated onto the ceramic substrate so as to cover the window portion, wherein only a part of an interface between the ceramic substrate and the thin diaphragm is joined to form a joint of the diaphragm. A diaphragm structure is free from instability caused by a breakage or deformation of a partition wall between window portions upon punching or laminating even if a diaphragm structure employs a design in which dimensions of a diaphragm portion is maintained and simultaneously a distance between diaphragm portions is made narrow to restrain a surface area excluding a diaphragm portion of a diaphragm structure or a design in which a plurality of diaphragm portion having various configurations and dimensions are disposed.

    摘要: A piezoelectric/electrostrictive device is provided in which a connection plate whose one end in the longitudinal direction is held by two diaphragms and whose other end is held by two other diaphragms is spanned between bottoms of faced concave portions formed on a substrate, and piezoelectric elements are arranged on at least a part of at least one-side plane surface of each of the diaphragms, and the diaphragms are connected with the sides of the concave portions in at least the direction for the diaphragms to hold the connection plate, and a fixing plate is connected to the connection plate so that the longitudinal direction of the fixing plate becomes parallel with the direction for the diaphragms to hold the connection plate. A displacement of the fixing plate generated by applying a voltage to the piezoelectric element is utilized or an electromotive force of the piezoelectric element based on a displacement of the fixing plate is utilized. The piezoelectric/electrostrictive device is preferably used as a positioning- or angle-adjustment mechanism of an optical unit or precision unit, a vibrator or resonator for communication or motive power, an oscillator, a discriminator, an ultrasonic sensor, or an acceleration sensor because the device is able to convert electric energy into mechanical energy such as a mechanical displacement, force, or vibration and vice versa.

    摘要: A vibration gyro sensor is constructed as follows. Namely, a detecting piezoelectric/electrostrictive element 12, which detects displacement generated in a direction perpendicular to a direction of vibration of a vibrator 2 when the vibrator is rotated, is provided on a detecting section. The detecting section is constructed by an integrated fired product made of ceramics together with the vibrator 2 and a support base 4. The detecting section is constructed by a first plate-shaped section 6 which is more thin-walled than the vibrator 2 and which has its principal surface extending in the direction of vibration. The piezoelectric/electrostrictive element 12 is formed in an integrated manner on the first plate-shaped section 6 in accordance with a film formation method. Further, a thin-walled second plate-shaped section 8, which is provided for decreasing rigidity in the direction of vibration and facilitating the vibration for the vibrator 2, is formed in an integrated manner so that its principal surface extends in the direction perpendicular to the direction of vibration. Accordingly, it is possible to obtain the vibration gyro sensor made of ceramics having excellent sensitivity, in which the characteristics of the vibrator are scarcely affected by an ambient magnetic field, processing or machining can be easily performed, and the electric characteristics can be advantageously adjusted.
