摘要： PURPOSE:To perform automatic detection of minute defects, foreign matters and the like in the inside and the surface of a metal sheath tube by arranging ultrasonic flaw detecting pieces so that the sum of the flaw detecting ranges of the metal sheath tube with the ultrasonic flaw detecting probes covers the entire circumference of the metal sheath tube. CONSTITUTION:Ultrasonic flaw detecting probes 2 are arranged under the state of the constant incident angle and incident path for the surface of the ultrasonic waves with respect to the surface of an aluminum tube 1. An ultrasonic wave 3, which is emitted from each flaw detecting probes 2, enters into the inside of the tube 1 after the propagation in the water. The ultrasonic wave is reflected from the surface of the flaw detecting piece 2 in halfway, foreign matterns, defects and the like in the surface and the inside of the pipe 1, and the echo waves are generated. The flaw detecting probes 2 repeat the emission of the ultrasonic wave and the reception of the echo waves at a high speed. An ultrasonic flaw detection controller 5 controls the emission of the ultrasonic wave and the reception of the echo waves with the respective flaw detecting probes 2, detects the foreign matterns, the defects and the like in the inside and the surface of the tube 1 and outputs detected signals 6 of the foreign matters, the defects and the like to a controller 31.

摘要： PROBLEM TO BE SOLVED: To detect a height position of gravity before a running device advances onto stairs to enable the safe transportation by calculating a position of gravity in a bottom face of a loading part from outputs output from a plurality of weight detectors provided in the loading part of the running device and measuring a travel amount of the position of gravity when the loading part is inclined to calculate the height position of gravity. SOLUTION: A loading part 5 is provided in a car body frame part 1 through weight detectors 7 (7a to 7d) provided at four corners of a bottom part thereof to calculate where a position of gravity of weight of the loading part is on a bottom face of the loading part based on the results of measurement of each weight detector 7. Moreover, with respect to the position of gravity in a bottom part of the loading part, a height of gravity is calculated by measuring a travel amount of the position of gravity and an angle of inclination when a running device is inclined. When the device runs on stairs, front and rear wheels 3, 4 for running on a flat surface are pulled in by driving lift mechanisms 13, 14, and a crawler running mechanism 2 is brought into contact with the ground to judge whether the device is within a proper scope for safety or not based on the comparison between the calculated value and actual value of the height of gravity in a condition in which the device is inclined.

摘要： PURPOSE:To take out insulating oil from a cylindrical doughnut-shaped cable storage rotary basket which is in a state of vacuum and rotation so as to pre vent generation of defectives by providing a communicating hole between a slit provided around the outer or inner periphery of the cylindrical doughnut- shaped cable storage rotary basket and the basket, and mounting a discharge pump on the bottom portion of the end of a pipe. CONSTITUTION:A cable storage rotary basket 5 stored in an impregnation tank 40 is so constructed as to be rotatable. An outer tube 29 is provided around the overall outer periphery of the rotary basket 5 and a slit 31 is provided between the rotary basket 5 and the outer tube 9. The slit 31 has a communicat ing hole 32 provided through the bottom portion thereof so that insulating oil is allowed to freely flow in from the rotary basket 5. At the bottom portion of the inside of the slit 31 an insulating-oil discharge pump 30 is connected to a pumping pipe 27 and is hung from the lid portion 3 of the impregnation tank through a sealing portion 24. The insulating oil can thus be taken out without any problem from the rotary basket inside the impregnation tank which is in a state of vacuum and rotation, and the work of normally feeding a cable is made possible, preventing generation of defectives.

摘要： PURPOSE:To improve the dimensional accuracy of the spacer which has an alternately S.Z-inverted spiral groove by rotating the spacer or a tension member in synchronism with the rotation of a rotary die. CONSTITUTION:A tension member sending-out device, an extrusion die 4 which extrudes a spacer raw material to the outer periphery of the sent-out tension member 51 and has a projection for forming the groove in the outer periphery of the spacer 52, and a take-up device which takes up the spacer 52 extruded by the die 4. Then when the alternately S.Z-inverted groove is formed by extrusion, the rotary die 4 and tension member 51, rotary die 4 and taken-up spacer 52, or the rotary die 4, tension member 51, and take-up spacer 52 are rotated synchronously. Consequently, the spacer 52 is obtained which has stable size accuracy of inversion pitch and a spiral angle.

摘要： PURPOSE:To enable to perform cooling control of a cooling side precisely, by a method wherein a fun motor performing cooling from the outside of a cylinder is provided and a motor speed is controlled analogically within a specific range by a signal from a PID control temperature adjusting meter. CONSTITUTION:Each PID control temperature adjusting meter 3 sends control output to a motor speed controller 2 corresponding thereto and to a heater power controller 6 corresponding to the same. Each of the motor speed controllers 2 performs PID control of the speed of a fan-driving motor 1 corresponding to the same, and each of the heater power controllers 6 perform PID control of an electric current applied to a heater 7 heating a cylinder 8 corresponding to the same. As the titled controller is so constituted that the outside of the cylinder 8 is cooled by making used of the fan-driving motor 1 to the speed of which PIC analogic control is applied within a range of 0-100%, temperature control accuracy can be improved.
