摘要： PROBLEM TO BE SOLVED: To provide a reliable piezoelectric stack whose performance cannot deteriorate easily, and to provide a method for manufacturing the piezoelectric stack. SOLUTION: Piezoelectric layers 111, 112 made of PZT and internal electrode layers 121, 122 are alternately laminated. In the crystal grain boundary of the piezoelectric layers 111, 112, a grain boundary fill factor by Pb-based glass is 95% or higher. When manufacturing the piezoelectric stack 1 by alternately laminating the piezoelectric layers 111, 112 made of PZT and the internal electrode layers 121, 122, Pb is more excessively contained than a stoichiometric ratio in PZT, and a non-burned sheet for the piezoelectric layers 111, 112 on which conductive paste for the internal electrode layers 121, 122 is printed is laminated for manufacturing a non-burned laminate. The non-burned laminate is baked in an oxygen atmosphere in which oxygen concentration is 40-100 vol.% so that the crystal boundary fill factor of Pb-based glass to the crystal grain boundary inside the piezoelectric layers 111, 112 becomes 95% or higher.

摘要： PROBLEM TO BE SOLVED: To solve a problem wherein rise of load continues even after pressure rising time t elapses and excessive peak load occurs to give load to a piezo-stack when timing for reaching the pressure rising time t is within 0.5 T±0.1 T, because synthetic resonance period T exists in the piezo-stack and a driving body. SOLUTION: When the pressure rising time from the start of charging to the reach of target charging voltage of the piezo-stack is t and the synthetic resonance period of the piezo-stack and the driving body is T, the pressure rising time t is set to satisfy the relation of 0.6 T≤t. Consequently, it is possible to avoid the inconvenience that the timing for ending charging and pressure rising of the piezo-stack and the timing for making load gradient the maximum value by the synthetic resonance period T are overlapped and make pressure rising gradient just before reaching the pressure rising time t gentle. As a result, peak load and dip load generated in the piezo-stack are suppressed and reliability of the piezo-stack for a long time is improved. COPYRIGHT: (C)2007,JPO&INPIT
摘要翻译：要解决的问题为了解决当压力上升时间t过去并且过度的峰值负载发生时负载的上升继续增加以在达到压力上升时间t的时刻在0.5T内给予压电叠层的负载的问题 ±0.1T，因为合成共振周期T存在于压电堆和驱动体中。解决方案：当从充电开始到压电堆叠的目标充电电压达到的压力上升时间为t，压电堆和驱动体的合成共振周期为T时，上升时间 t设定为满足0.6T≤t的关系。因此，可以避免结合压电堆的充电定时和压力升高的定时以及通过合成共振周期T使负载梯度达到最大值的时刻的不便，并且在达到之前使压力升高梯度压力上升时间t温柔。结果，抑制了在压电堆叠中产生的峰值负载和浸渍负载，并且提高了长时间压电叠层的可靠性。版权所有（C）2007，JPO＆INPIT
