    • Top and bottom frame supports are spaced apart and secured together by central end posts (20). Downwardly opening grooves along the arcuate edges of the top frame support align with upwardly opening grooves along the arcuate edges of the bottom frame support to form mating tracks into which credit cards (40) are inserted. The credit cards bend into the shape of the grooves and overlap with two cards on each side to form side to form side enclosure surfaces which enclose a storage space (43) between the cards on each side and the top and bottom frame supports for storing money and other valuables. A holder (25) with a key, pen, knife, or other device may be inserted in a notch (37) in the top frame support. Alternately the framed supports may be hinged together at one end to form a hinged clamshell-type container.
    • 顶部和底部框架支撑件间隔开并通过中心端柱(20)固定在一起。 沿着顶部框架支撑件的弓形边缘的向下开口的凹槽沿着底部框架支撑件的弓形边缘与向上开口的凹槽对准,以形成信用卡(40)插入其中的配合轨道。 信用卡弯曲成凹槽的形状并与每一侧上的两个卡片重叠以形成侧面以形成侧部封闭表面,该封闭表面包围每侧上的卡片之间的存储空间(43)和用于存储钱的顶部和底部框架支架 和其他贵重物品。 具有钥匙,笔,刀或其他装置的支架(25)可插入顶架支架中的凹口(37)中。 替代地,框架支撑件可以在一端铰接在一起以形成铰接的蛤壳式容器。

    • An electroacoustic transducer having a tail mass, a head mass and at least two parallelepiped shaped piezoelectric material elements disposed between and attached to the tail mass and the head mass is provided. The tail mass has a body extending between a first end and a second end, the body having a cavity with a cavity wall and the cavity extending from the first end towards the second end. The head mass has a head and an elongated shaft attached to and extending from the head, the shaft having a shaft axis and being located at least partially within the cavity of the tail mass. The at least two parallelepiped shaped piezoelectric material elements are made from a piezoelectric material having a non-zero d 3y shear piezoelectric coefficient where the d 3y coefficient can be d 34 , d 35 or d 36 .
    • 提供了一种电声换能器,其具有尾部质量,头部质量和设置在尾部质量块和头部质量块之间并附着到尾部质量块上的至少两个平行六面体形状的压电材料元件。 尾部质量具有在第一端和第二端之间延伸的主体,主体具有腔体,腔体具有空腔壁,腔体从第一端部朝向第二端部延伸。 头部具有附接到头部并且从头部延伸的头部和细长轴,该轴具有轴线并且至少部分地位于尾部质量块的空腔内。 至少两个平行六面体形状的压电材料元件由具有非零d3y剪切压电系数的压电材料制成,其中d3y系数可以是d34,d35或d36。
