摘要： The distal end of an insertion section of an endoscope is divided into a plurality of segments each including a pair of SMA coils which are arranged symmetrically with respect to an axis and memorize a close-winding shape. As the SMA coils recovers their memorized shape, the distal end of the insertion section is bent. The SMA coils are restored to the memorized shape when they are conductively heated by means of a current supply circuit. The current supply circuit comprises an input unit for inputting a target value of the bend angle for a leading segment, a sensor for detecting the distance of insertion of the insertion section, a detector circuit for detecting the bend angle of each segment, and means for controlling the amount of current supply so that the bend angle of the SMA coils agrees with a target angle. The inputted angle is set as the target angle for the leading segment, and the detected bend angle of each segment is set as the target angle for each succeeding segment. The set value is renewed each time the insertion distance of the insertion section attains a predetermined distance.

摘要： An endoscope includes a bending member having a shape memory alloy. A pair of heating current supplying wires and a pair of resistance detecting wires are connected at one end to the ends of the shape memory alloy. The other end of the heating current supplying wire is connected to a current supply circuit, and the other end of the resistance detecting wire is connected to a resistance detector. The resistance detector is constituted by a bridge circuit having a branch opened and the shape memory alloy is connected in the opened branch via the resistance detecting wires. A controller controls the current supply circuit according to the detected resistance. The current supply is effected by supplying a current pulse, and the amount of heating current and the bending degree can be controlled by controlling the pulse width of the current pulse. Since no heating current is supplied to the resistance detecting wires, the resistance thereof is not changed even when the shape memory alloy is heated by passing a heating current therethrough. Therefore, it is possible to precisely detect variation in the resistance of only the shape memory alloy member and measure the bending degree of the bending member.
摘要翻译：内窥镜包括具有形状记忆合金的弯曲构件。一对加热电流供应线和一对电阻检测线在一端连接到形状记忆合金的端部。加热电流供给线的另一端与电流供给电路连接，电阻检测线的另一端与电阻检测器连接。电阻检测器由具有分支开口的桥接电路构成，并且形状记忆合金经由电阻检测线连接在开启的分支中。控制器根据检测到的电阻来控制电流供应电路。通过提供电流脉冲来实现电流供应，并且可以通过控制电流脉冲的脉冲宽度来控制加热电流和弯曲程度。由于没有向电阻检测线供应加热电流，所以即使形状记忆合金通过加热电流而被加热，其电阻也不会改变。因此，可以精确地检测形状记忆合金构件的电阻的变化并测量弯曲构件的弯曲度。

摘要： A cavity insert device comprising an insert section capable of being inserted into tracts and cavities, a detection circuit for detecting conditions of components making up the device, such as an observation device formed at the distal end side of the insert section, and a fuzzy inference section for synthetically determining a plurality of information signals outputted from the detection circuit and producing control signals to control the components. The fuzzy inference section employs inference rules which are empirically considered to be desirable, and control is made by the control signals obtained with the fuzzy inference. The device is thus operated in a nearly optimum state.
