摘要： PURPOSE:To improve the heating efficiency of the captioned device by tilting and moving high-frequency heating coils in follow-up to the core metal whose inclination changes with a receiving roll as a fulcrum at the feeding of the work. CONSTITUTION:At the time of inserting the tubular work onto a core metal 3 from its stem part, a contact body 17 oscillates about an oscillating axis 17a while making contact with the core metal 3 tilting with a receiving roll 11 as a fulcrum. The oscillating angle of this contact body 17 is measured accurately by the inclination detector 21 provided to a stand 16. A tilting table 15 is tilted by the operation of the actuator 23 which is controlled by a detector 21. Namely, it turns out that the tilting table 15 tilts in follow-up to the core meral 3 and therefore the coils to be respectively built in coil containers 18, 19, 20 mounted to the tilting table 15 tilt and move while maintaining always a fixed relative positive with respect to the core metal 3. Hence, the spacing between each coil and core metal 3 may be narrowed down to a minimum required limit with respect to the work, whereby the heating efficiency may be improved.

摘要： PROBLEM TO BE SOLVED: To display and judge the cause of non-operation by distinguishing that the operation is stopped caused by clogging of foreign matters in a guide vane from that the operation is stopped caused by abnormalities of a guide vane switching mechanism itself. SOLUTION: When foreign matters are clogged in a guide vane, a tip metal fitting 11 is positioned and fixed. At this time, when a rod 10 is moved in the opining direction, a detecting spring receiver 53 is slid in the opening direction against a spring 54 and brought into contact with a detecting upper case 51. Simultaneously, a detecting lower case 52 is approached to a flange 21. Therefore, a non-contact detector 56 detects that the gap distance between the case and the flange 21 is decreased, a display 57 continuously displays that the operation is stopped caused by clogging of foreign matters.

SOLUTION: A trapezoidal screw abrasion measuring apparatus, in which the motion of an object is controlled through a trapezoidal screw by driving a servo motor, is providing screw abrasion measuring apparatus 11a, 11b on both the screw shaft 5 side and screw nut 6 side of the trapezoidal screw. These measuring apparatuses 11a, 11b measure the end face of the screw shaft 5 and the position of a dog which is fixed to a trapezoidal screw nut 6 on the trailing end side of the trapezoidal screw. Abrasion is determined, based on the measurements on the trapezoidal screw shaft 5 side and the trapezoidal screw nut 6 side, so that abrasion of the structure of the trapezoidal screw can be detected both, when it is loaded in the opening direction and closing direction of a needle valve. According to the arrangement, abrasion of a trapezoidal screw can be measured easily.

摘要： PURPOSE:To reduce influence on self-enclosing force of a hydraulic turbine guide vane at the time of loss of an electric source and to prevent the hydraulic turbine guide vane from coming not to be closed at the time of loss of the electric source. CONSTITUTION:It is devised to transmit input from the side of a hydraulic turbine guide vane only to an output gear 2 by opening and closing the hydraulic turbine guide vane by way of reciprocally driving a connecting metal fitting 14 by driving of an electric motor by means of connecting the electric motor and the output gear 2 with each other by an electromagnetic clutch 23 at the normal time and by releasing connection of the electric motor and the output gear 2 by the electromagnetic clutch 23 at the time of loss of an electric source by way of interposing the electromagnetic clutch 23 connected as it is magnetized between the electric motor and the output gear 2. Additionally, it is devised to prevent the hydraulic turbine guide vane from coming not to be closed at the time of loss of the electric force by devising the electric motor not to give influence on input from the side of the hydraulic turbine guide vane at the time of loss of the electric source, reducing operating physical force at the time of reverse rotation at the time of loss of the electric source and reducing influence on self-enclosing force of the hydraulic turbine guide vane at the time of using it by way of combining it with a hydraulic turbine furnished with the self-enclosing force of the hydraulic turbine guide vane itself.

摘要： PROBLEM TO BE SOLVED: To provide a labyrinth seal structure of a vertical-shaft rotating machine capable of improving the sealing performance in operation, and preventing the leakage of the lubricant even when the operation/stop are repeated. SOLUTION: A movable blade mechanism 40 and a lubricant returning mechanism are mounted at a rotating labyrinth side. In the movable blade mechanism, a movable blade part 41 is guided to a female screw part 47 by the energizing force of a spring 51 and upwardly moved while rotated to close the lubricant return channel 42 at a channel opening and closing part 44 in the stop of the rotation, and the movable blade part is guided to the female screw part against the energizing force of the spring by the wind pressure acting on a blade part 43 and downwardly moved while rotating to open the lubricant returning channel at the channel opening and closing part in the rotation. In the lubricant returning mechanism, a ball is radially inwardly moved by the energizing force of the spring to close the lubricant returning channel in the stop of the rotation, and the ball is radially outwardly moved against the energizing force of the spring by the centrifugal force acting on the ball to open the lubricant returning channel in the rotation.

摘要： PROBLEM TO BE SOLVED: To decrease conformation and the capacity of an electric servo motor and to reliably stop a water turbine during a loss of a power source. SOLUTION: Through drive of an electric servo motor 5, a movement conversion part 6 is reciprocatively moved and through operation of a deflector operation rod 3 and an oscillating link 2 for a deflector, the deflector is opened and closed and simultaneously, a water receiving container 10 coupled to an oscillation link 4a is elevated through a wire rope 8. Since, during normal operation of a power source, the water receiving container 10 is in an empty state, the operation force of the electric servo motor 5 may be reduced. During a loss of the power source, a motor-driven emergency shutdown valve 14 is opened, water 20 in a hydraulic iron pipe 13 flows in the water receiving container 10 through a piping 12 and the water receiving container 10 filled with water 20 is increased in weight and lowered. Thereby, a wire rope 8 is stretched, the movement conversion part 6 is moved in a closing direction, and the electric servo motor 5 and a deflector are closed.
