摘要： PURPOSE:To simply detect the landing of a moving investigation member even under a visual field non-acting state, by providing a detection member for detecting the pressure received when the moving investigation member lands regardless of the revolving position of said member to the outer periphery of the moving investigation member. CONSTITUTION:A large number of detection members 8 for detecting the pressure applied to a moving investigation member 2 are arranged to the outer periphery of the moving investigation member 2 in the short axis direction thereof at a predetermined pitch. At the time of such a state that the pressure from the surface 5 of the sea bottom is applied to the moving investigation member 2 even when the moving investigation member 2 is landing on the surface of the sea bottom, the spring 6 of at least one detection member 8 is compressed in the direction shown by an arrow so that a pin 3 is brought into contact with a contact 7 and the opening and closing state of the pin 3 and the contact 7 is indirectly detected by a means composed of a transmission apparatus for transmitting said state to a ship by an electric signal.

摘要： PURPOSE:To obtain a surface flaw detector for wire rods which is free from disconnection even when the detector is of a contact type, does not require any change even when the diameter of a wire rod varies, and has high detecting sensitivity by supporting the detector with a guide roll and detecting the surface flaw of the wire rod while the front ends of detecting elements are brought into contact with the wire rod under a prescribed pressure. CONSTITUTION:A wire rod 1 is moved at a prescribed speed and each piezoelectric element 3 continuously outputs a constant voltage signal V0 from its front end section 30. When the surface flaw of the wire rod l comes into contact with the element 3, the element 3 is deformed and a stress is generated in the element 3 due to the deformation. Since a fluctuating voltage DELTAV is generated based on the stress, the element outputs a voltage signal of V0+DELTAV. The voltage signal is passed through a filter circuit 4 and, after a noise component is blocked by its frequency, only the band of a frequency (f) is outputted to an amplifier circuit 5. The circuit 5 amplifies the signal V0+DELTAV from which the noise component is removed and outputs the amplified signal to a recorder 8 as the surface flaw measured results of a comparator circuit 7 and each element 3.

摘要： PURPOSE:To detect degradation without arranging an electrical induction circuit at a sensor section by providing a vibration applying device, a sound sensor, a reference signal comparator, and a device for producing an abnormal signal. CONSTITUTION:The degradation searching device 10 is constructed such that the driving force of traveling pulleys 11, 11' and a motor 16 is transmitted through a rotary shaft 17, a gear 19, a rotary shaft 17', and a gear 20 thus self running the device 10 back and forth, as shown by an arrow, on n wire 1. Then the wire 1 is hit by means of a hammer 12 to produce vibrating sound which is caught by a sound sensor 22 arranged closely to an auxiliary pulley 11'', and a signal is provided from the sound sensor 22 to a detection unit 24. Upon detection of abnormal signal, the detection unit 24 transmits the abnormal signal through a transmitter/receiver 25 and an antenna 25a to a remote operating unit. Since hitting system is employed, the device is not subjected to induction and degradation of inner layer can be detected reliably.
