Title: Litao3 piezoelectric oscillating element
Inventor: FUJIWARA YOSHIAKI
IPC: H03H9/17
Filed: 1982-07-07
Abstract: PURPOSE:To obtain an oscillating element of high quality which increases a product region where a single resonance mode is obtained with a reduced spurious mode, by clearing up the relationship between the oscillating energy shut-in quantity optimum to the normal room temperature and the rotating direction around Y axis of a crystal and then shifting the peak temperature of the frequency temperature characteristics to the corresponding room temperature. CONSTITUTION:A relationship is defined as zeta=theta/8.theta+(0.65+ or -0.1) between the revolving angle theta around Y axis of a single crystal of an X plate and the shut-in quantity of oscillating energy. Curves A-E show the temperature characteristics of various samples of different energy shut-in quantities zeta. A curve F shows the relationship between the energy shut-in quantity Z and the angle theta with which the peak of the temperature characteristic curve is equal to a normal room temperature (23 deg.C). A dotted line G shows the upper limit value (zeta=125) of the shut-in quantity with which an oscillator has a single mode. As shown clearly in the diagram, an approximate equation zeta= theta/8+0.65 is satisfied with the curve F which has the quantity zeta of <=1.25 at room temperature. If the ambient temperature at which an oscillator is used is set at said room temperature + or -5 deg.C, an approximate equation zeta=theta(0.65+ or -0.1)/8 is satisfied for a curve equivalent to the curve F.

Abstract: PROBLEM TO BE SOLVED: To improve capacity and rapid charge/discharge characteristics of a battery by regulating a crystal size to a prescribed range according to anisotropy of a crystal particles of a major composition phase and using it for an electrode in an allay whose composition is expressed by a fomaula and which is composed of two phases or more. SOLUTION: In an alloy having such a composition and a phase, when a major composition phase is a crystal particle without any anisotropy, the mean crystal particle size is set to 5-100μm, when the major composition phase has anisotropy containing a branched structure, the mean value of the crystal size in the direction crossing at right angles with the longitudinal direction is set to 5-100μm. This constitution reduces the major/subsidiary composition phase interface which increases with the lowering and its too lowering of the discharge capacity caused by major composition phase diffusion controlled current by enlargement of the crystal particle size of the major composition phase, and suppressed lowering of the discharge capacity caused by reduction of trap site of hydrogen.  Energy density per volume and weight can be thus enlarged. [In the formula, R is composed of one of B and Co or more, 0<=x<=0.9, 0.7<=a<=1.5, 0.05<=b<=0.6, 0.05<=c<=0.9, and 0.005<=d<=0.3].
