Abstract: PROBLEM TO BE SOLVED: To solve a problem wherein a conventional traveling vehicle having individually drivable wheels may not make a turn due to insufficient torque when performing a ultra-pivotal brake turning.
SOLUTION: When making a turn of a traveling vehicle 1 having right and left front wheels 3 and rear wheels 4 which are individually drivable, and a manipulator 5 to be developed forward of a vehicle body, the manipulator 5 is developed forward of the vehicle body to shift the center of gravity of the vehicle body forward of the vehicle body, and the right and left front wheels 3, 3 are driven opposite to each other. In this turn control method, the distance from the center of gravity of the vehicle body to the front wheels 3 is reduced to enable the rotation with a low torque, and the resistance at the rear wheels 4 and the friction force with the ground are reduced to enable a smooth ultra-pivotal brake turning even by a driving motor 7 of the relatively small output.

Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic flaw detection device for a welded portion of a pipe capable of using a light weight, inexpensive and small sized device. SOLUTION: An ultrasonic flaw detection device comprises an ultrasonic probe 2 which is inclined at a prescribed angle to a probe that is put into a pipe 1 filled with a liquid and an ultrasonic probe 3 which is inclined at an angle symmetrical with the inclined angle of the ultrasonic probe 2. One ultrasonic probe 2 emits an ultrasonic wave toward a welded part of the pipe 1 and receives the reflection wave from the welded part. The other ultrasonic probe 3 receives the reflection wave from a surface of an inner section of the pipe. Switches 7, 36 that switch the operations of the two ultrasonic probes 2, 3 and a judging means 36 that judges a defect based on the two reception results from the identical welded part by virtue of the switches, are provided.

Abstract: PURPOSE:To make rail fasteners fixed and removed certainly by mechanical means while saving man power and reducing work hours by a method wherein loosening and tightening of bolts can be executed smoothly even in the case where errors exist in placing a boltunscrewing device exactly over the head of a bolt. CONSTITUTION:Bolts are unscrewed with a bolt-unscrewing device 18 while working trucks on the right and the left are moved in the direction opposite to the direction in which a traveling truck moves forward at a fixed speed, and a rail fastener is removed from a sleeper. Errors existing in placing the bolt-unscrewing device 18 over the head of the bolt is offset by a support device 35 and an elastic centering device 42 and at the same time, fitting of a fitting hole 44 to the bolt head is made smoothly by virtue of a skirt 46.

Abstract: PURPOSE:To increase a tracing property at the suction time of a wall face suction unit to an inclined wall face, etc., by inserting a lock piece freely slidably into the hole extended in the 2nd rotation shaft center direction of one part of the members composing a joint. CONSTITUTION:A wall face suction unit 10 is fitted via a universal joint 12' and joint 23 to a free end frame 4, the drooping of the unit centering around the shaft center at the wall face moving time of a robot is prevented by an outer cable 15 and a parallel holding mechanism 17 composed of the outer cable 15 and the inner cable 16 interposed with an elastic telescopic member 27 on the way. Moreover the wall face inclination in the direction that the unit 10 is turned with a shaft center O1 as the center is absorbed by the extension of the member 27 or the deflection of the cable 16 and the rotation around the shaft center O1 of the joint 12' by the deflection of a twist coil spring provided on the joint 12', and the wall face inclination in the direction that the unit 10 is turned centering around a shaft center O3 is absorbed by the shaft center O3 rotation of the joint 23 by retracting the lock piece inside the joint 23 against the elastic body.

Abstract: PURPOSE:To reduce the inductance produced by the coiling of a cable by successively winding the cable around two drums in such a specific manner that the cable is stretched from one drum to the other in parallel with the outside of the space between the drums after the cable is put around the drums in a state where the cable intersects itself in the space between the drums forming the shape of the figure '8'. CONSTITUTION:A cable 1 is successively wound around take-up drums 2 and 3 by repeating such a winding cycle that, after the cable is put around the drums 2 and 3 in a state where the cable 1 intersects itself in the space between the drums 2 and 3 forming the shape of the figure of '8', the cable is stretched from one drum 2 to the other drum 3 in parallel with the outside of the space between the drums 2 and 3 and put around the drum 3. After the drum 3, the cable 1 is obliquely stretched from one side of the drum 3 to the other side of the drum 2 crossing the space between the drums 2 and 3, and then, stretched from the drum 2 to the drum 3 in parallel with the outside of the space. The cable 1 is then obliquely stretched from the other side of the drum 3 to one side of the drum 2 crossing the space. Therefore, the inductance produced by the coiling of the cable 1 around the drums 2 and 3 can be reduced and the limitation to the winding length of cables can be relieved.
