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

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method of a laminated dielectric element wherein the faultiness of its delamination, its crack, and its deformation, etc. are scarcely generated, and the laminated dielectric element of a high quality can be manufactured.
SOLUTION: The manufacturing method manufactures a laminated dielectric element 1 wherein dielectric ceramic layers 12 containing lead in their compositions and base-metal electrode layers 13 made of a base metal are laminated alternately. The manufacturing method performs an electrode printing process, a compressive bonding process, a degreasing process, and a baking process. In the electrode printing process, a paste material for the base-metal electrode is applied to each ceramic green sheet made of each ceramic material molded in the form of a sheet. In the compressive bonding process, the ceramic green sheets are so laminated mutually and are so bonded compressively to each other as to create a laminate. In the degreasing process, the laminate is heated in a heating furnace under the flow-through of the atmospheric gas containing a water vapor and inert gases. In the baking process, the laminate is baked. Also, in the degreasing process, the metal ions are fed for promoting the decompositions of organic matters.
