摘要： PURPOSE:To stabilize the operation of permanent magnets in mounting and demounting onto a wall surface and the shift on the wall surface by installing supporting points for supporting the attraction force generated between the permanent magnets and the wall surface when the permanent magnets of absorbing units are mounted and demounted, into the absorbing units. CONSTITUTION:A wall-surface traveling machine is equipped with a pair of absorbing units 31 and 41 in front and in rear. Said absorbing units 31 and 41 are shifted back and forth by the drive of propulsion mechanisms 38 and 48 by actuators 37 and 47. Said absorbing units 31 and 41 are equipped with permanent magnets 32 and 42 attached onto the wall surface 40, actuators 33 and 43 for mounting and demounting the permanent magnets 32 and 42 onto the wall surface 40, and supporting points 34 and 44 for supporting the attraction force in the case when the permanent magnets 32 and 42 are mounted and demounted. By the installation of the supporting points 33 and 43, the magnetic attraction force generated in the case when the permanent magnets 32 and 42 are mounted and demounted is not transmitted to a body 39 balanced in the closed system surrounded by the frame 41 of the absorbing unit and the wall surface 40.

摘要： PURPOSE:To obtain a controlling communicating device which does not limit the function of a mobile body by restricting a photo transmitter and detector so that bidirectional optical communication is attained at all times between plural satellite stations connected to a console by a cable communication means and mobile bodies. CONSTITUTION:A mobile car 2 used for the inspection in an atomic reactor container is connected with an optical radio system using an optical transmission line 10 among plural satellite stations 5 allocated in a running space and a wired transmission line 6 is connected between the satellite stations 5 and a central station 3 in the console 1. Universal heads 9l, 9s are controlled so that the photo transmitter/detector 7l, 7s for optical radio system are opposed to each other at all times in following to the running of the mobile body 2. The position of the mobile body 2 is calculated from the up/down, left/right turning angle of the transmitter/detector 7l, 7s, and the central station 3 selects sequentially the satellite stations 5 in communication with the mobile station 4 in response to the position of the mobile body 2.

摘要： PURPOSE:To enable an inspection of even a bent pipe of an elbow, etc. by connecting an inspection car and travelling car with a coil spring and by connecting a travelling car and powe car with a flexible shaft. CONSTITUTION:The tip part of an inspection car 27 is brought into contact with the inner wall face of an elbow 45 when the travelling device for inspection of the inside of a pipe travels the pipe inside and arrised at the bent pipe position of an elbow, etc. However, the tip part of the inspection car has a smooth spherical shape and yet the coil spring 26 is flexible, so by pushing the inspection car 27 with the travelling car 22 it is advanced along the wall face of the elbow 45 and the progress of the travelling car is enabled similarly as well. Also a flexible shaft 13 is flexible and by pulling the flexible shaft 13 with the travelling car 22 the power car 7 is passed through a elbow 45. Consequently the travelling device for the pipe inside the inspection can pass through the elbow 45 with the inspection car as a guide without taking a special direction and posture control.

摘要： PURPOSE:To receive a signal with good quality by extracting a horizontal synchronizing signal or a vertical synchronizing signal included in a composite video signal as a standard signal for supervising a reception level and supervising a minimum level in response to a reception sensitivity so as to prevent that a command signal does not reach a mobile body and the mobile body cannot return any more. CONSTITUTION:The composite video signal 300 is extracted from a monitor 7 and transmitted to a synchronizing separator circuit 31. A horizontal synchronizing signal 301 separated by the synchronizing separator circuit 31 is converted into an n-bit digital quantity by an A/D converter 33 and fed to a comparator 34, and when the result is smaller than the level set by a digital switch 35 in advance, an alarm signal 304 is outputted to an error processing section 36.

摘要： PURPOSE:To obtain a drop preventive sensor which is applicable onto an uneven floor, too, by constituting so that a supporting part for supporting a wheel so as to be movable downward vertically, and also the wheel can be moved upward by a radius portion or more. CONSTITUTION:A small wheel 42 is supported by a rotatable bush 43, can move upward and downward, and the bush 43 is always kept horizontally by a spring 44. A motion of a wheel is transmitted to an arm 45, and only when the tip of the arm is in a position of a photoswitch 46, the switch becomes off. Even if a wheel 42 encounters a large projecting part, it can be avoided by its movement in the upper direction and a rotation of the bush 43. Also, only when the wheel 42 falls downward vertically, the tip of the arm 45 closes up an air-gap of the switch 46, the switch is changed over, and danger of a drop of a main wheel is detected beforehand.
