摘要： PURPOSE:To achieve a higher performance of the distance amplitude compensation by selecting sound velocity with parallel setting devices to performing sensitivity slopes corresponding thereto after starting and stopping positions are set for a distance amplitude compensation circuit. CONSTITUTION:Setting device 5-1-5-n are operated in the mm. unit with a switch for setting the positions of starting and stopping a distance amplitude compensator to select clock A signal 2, B signal 3 and C signal 4 in counters 6-1 and 6- 2 with the selection of sound velocity and then, input the signals to a multitriggering circuit 7. A sensitivity curve is outputted by turning ON or OFF slope generation circuits 8-1-8-n according to a trigger signal of the circuit 7 and after converted into analog with a D/A converter 9, it is amplified and outputted (a) with an amplifier 10. With such an arrangement of a circuit, the selection of sound velocity can be done for various object to be inspected broad or deep in the inspection range and intermediately changeable in the material quality thereby enabling compensation of distance amplitude in the mm. unit of distance range and ultimately providing an echo of the same height.
摘要翻译：目的：为了实现距离幅度补偿的更高性能，通过使用并行设置装置选择声速来执行在启动和停止位置之后对应的灵敏度斜率用于距离幅度补偿电路。规定：设备5-1-5-n以mm为单位。单元具有用于设置启动和停止距离幅度补偿器的位置的开关，以选择声速来选择计数器6-1和6-2中的时钟A信号2，B信号3和C信号4，然后输入信号到多重触发电路7.通过根据电路7的触发信号接通或关闭斜坡发生电路8-1-8-n并在用D / A转换器9转换成模拟之后输出灵敏度曲线用放大器10放大并输出（a）。利用这种电路的布置，可以在检查范围内对要检查的各种被检查的各种物体进行宽度或深度的声速选择，并且可以在材料质量中间进行变化，从而使得能够距离振幅的补偿在mm。距离范围单位，最终提供相同高度的回声。

摘要： PURPOSE:To make positioning of an inspecting device easy under water by pushing a submergence inspecting device onto the inner face of a container with a thrust of a propeller and running it on the inner face of a container. CONSTITUTION:An inspecting container 22 is positioned at the bottom of a cavity pit 23 and the periphery is surrounded by a concrete wall body 24. A submergence inspecting device 21 stops a cable 29 at specified winding-down position by a lifting winch 27. Then the submergence inspection device is moved to a desired direction with propellers 42 and 43 and pushed onto the inner face of the container 22 by a thrust of propellers. In this condition, a total direction wheel 48 is driven to travel on the inner face of the container 22. Thereafter the driving of the wheel 48 is stopped at a desired position (an optional position within a mobile range of a manipulater mechanism 46) and by driving the manipulater mechanism 46, a flaw detection is performed by placing a probe 47 at the predetermined detecting object position of the container 22.
