    摘要: In a production method of a piezoelectric element, an unneeded electric field is prevented from being applied to a piezoelectric thin film layer during the production process, resulting in a high performance piezoelectric element production method. The production method includes a first process for depositing an under electrode layer, a piezoelectric thin film layer and an upper electrode layer successively on a substrate such that the under electrode layer and the upper electrode layer form a short-circuit, a second process, after the first process, for etching including dry etching, the second process commenced while the under electrode layer and the upper electrode layer are short-circuited, a third process, after the second process, for polarizing by applying a voltage across the under electrode layer and the upper electrode layer, a fourth process, after the third process, for individualizing each piezoelectric element.

    摘要: A method for fabricating a piezoelectric element capable of ensuring high piezoelectric characteristics by preventing generation of unnecessary electric field in a piezoelectric thin film layer during the fabrication process. The method for fabricating a piezoelectric element comprises a first step for depositing a lower electrode layer, a piezoelectric thin film layer and an upper electrode layer sequentially on a substrate, a second step for performing etching including dry etching, a third step for performing polarization by applying a voltage between the lower electrode layer and the upper electrode layer, and a fourth step for segmenting into individual piezoelectric elements wherein the lower electrode layer and the upper electrode layer are held in short circuit state at least when dry etching is performed.

    摘要: A second blade-driving mechanism includes second blade-driving first member and second blade-driving second member, only the second blade-driving second member is rotated against elastic force of a blade-driving spring while the second blade-driving first member engages and is locked by a locking member at start of cocking operation of the cocking member to keep a second blade covering an exposure aperture, and the second blade-driving first member is disengaged from locking member at final stage of cocking operation, so the second blade-driving first member can be rotated by elastic force of a second blade-cocking spring and the second blade is made to open the exposure aperture. Staring cocking operation of a focal plane shutter is possible irrespective of the length of time during which imaging information can be transferred from an image sensor to storage via an information-processing circuit.
