    • An improved ultrasonic mechanical sector scanning transducer assembly is disclosed. An ultrasonic transducer is disposed for movement within a generally tubular housing. A drive element extends longitudinally within the housing and is coupled for transmitting motion to the transducer. Power drive apparatus produces oscillatory rotative movement of the drive element and transducer. A diaphragm seal, comprising a resilient tubular membrane, provides a liquid tight seal between longitudinally displaced interior sections of the housing. The tubular membrane has one relatively narrow end and flares along its length to a wider opposite end. The narrow end is bonded about the drive element. The wider end is affixed about the periphery of the housing. A coaxial cable is coupled to the transducer and extends to the exterior of the housing. The cable is wrapped within a spiral groove extending about the outer surface of a spool or reel mounted for movement in unison with the transducer.
    • 公开了一种改进的超声波机械扇形扫描换能器组件。 设置超声换能器用于在大致管状的壳体内移动。 驱动元件在壳体内纵向延伸并且被联接以将运动传递到换能器。 动力驱动装置产生驱动元件和换能器的振荡旋转运动。 包括弹性管状膜的隔膜密封件在壳体的纵向移位的内部部分之间提供液密密封。 管状膜片具有一个相对较窄的端部,并沿其长度向较宽的相对端延伸。 窄端围绕驱动元件结合。 更宽的端部围绕壳体的周边固定。 同轴电缆耦合到换能器并延伸到壳体的外部。 电缆缠绕在围绕安装成与换能器一致运动的线轴或卷轴的外表面延伸的螺旋槽内。
