摘要： A piezoelectric power generator that includes a support body, a piezoelectric element, and a bias compressive stress applying member. The piezoelectric element is placed on the support body. The piezoelectric element has a piezoelectric plate that is polarized in the thickness direction, and first and second electrodes that are each provided on a surface of the piezoelectric plate. The bias compressive stress applying member is supported on the side above the piezoelectric element by the support body. The bias compressive stress applying member applies to the piezoelectric element a bias compressive stress acting in the thickness direction of the piezoelectric plate, so that the magnitude of a compressive stress in the piezoelectric plate changes with a change in externally applied stress.

摘要： A vibrator includes a vibrating body having a substantially quadrangular prism shape and including four side surfaces extending in the longitudinal direction of the vibrating body. A common electrode is formed on substantially an entire surface of one of the side surfaces of the vibrating body. Split electrodes extend in the longitudinal direction on another side surface opposite to the side surface on which the common electrode is formed, and are spaced from each other in the width direction of the side surface on which the split electrodes are formed. In the vibrating body, a first polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the split electrodes. A second polarized section is polarized in a direction from the side surfaces of the vibrating body that do not have an electrode disposed thereon, toward the common electrode. Thus, the vibrator does not include a joint layer, and is polarized in opposite directions in the thickness direction.

摘要： A method of detecting an angular velocity including generating a differential signal from a vibrator, the differential signal having a Coriolis force proportional to angular velocity if the vibrator is rotated; generating a timing signal based on the differential signal; and applying the differential signal to a voltage-time converter which, based on the timing signal, converts the differential signal to a pulse train having a duty cycle proportional to the angular velocity. The method is implemented in an angular velocity detector, such as a gyroscope.

摘要： The vibrator includes a columnar vibrating body consisting of a piezoelectric material. The vibrating body is formed into a polygonal or cylindrical column and, when necessary, a through hole is formed axially thereof. Furthermore, the vibrating body is polarized. On side faces of the vibrating body, at least three external electrodes are formed. Also, when the through hole is to be formed, an internal electrode is formed on its inner circumferential surface. By applying the driving signal to these electrodes, the vibrating body bends and vibrates. And, when the rotational angular velocity is applied to the vibrating body about its axis, a coriolis force is produced responsive thereto. By this coriolis force, the vibrating direction of the vibrating body changes, and a voltage is produced between the two external electrodes. By measuring the voltage, the rotational angular velocity applied to the vibrator can be measured.

A header passage for a lubricant is formed along a core of the spline shaft and oil passages are further formed in the spline shaft in such a manner as to pierce therethrough radially from the header passage. At least one of the outward spline teeth of the spline shaft is provided at the top thereof with a groove crossing transversely the outer spline tooth so as to have the open end of the oil passage disposed in the groove.

摘要： A piezoelectric fan includes a tuning-fork type vibrator having two sides. A first piezoelectric element is formed on each of the two sides of the vibrator. Further, an exciting electrode is formed on each of these first piezoelectric elements. Also, a feedback electrode is formed on one of the first piezoelectric elements an electrically insulated from the exciting electrode. Furthermore, a blade is attached to the tip of each of the two sides of the vibrator. Then, this piezoelectric fan is driven in a self-exciting fashion by feeding an output from the feedback electrode to the exciting electrode. Also, in this piezoelectric fan, a vibrational node is formed at nearly the middle point of the vibrator at free vibration.
