摘要： PROBLEM TO BE SOLVED: To easily post-fit the device to the existing door by pivotably supporting an oscillating arm on a shaft support part provided on a connecting member of a door side surface, and providing a clearance shielding member on a lower void of a door through a support hole at the tip. SOLUTION: The side surface of a door 1 is provided with a connecting member 2 formed by a net plate. A holding member 11 is pivotably supported on the back of the connecting member 2 taking a shaft bearing part 10 as a falcrum. An oscillating arm 5 is integrally installed with the terminal part 3 screwed on the holding member 11. A shielding member 6 is fitted to the tip 4 of the oscillating arm 5. Thus, the connecting member 2, the holding member 11, the oscillating arm 5 and the shielding member 6 are integrated with the door 1 to be oscillated in the horizontal direction. The oscillating arm 5 has the terminal part 3 projected to the side of the door 1 by a torsion spring in the return state, and the tip 4 is raised. When the door 1 is closed, the terminal part 3 of the oscillating arm 5 is pressed to the vertical frame, the tip part 4 is lowered, and the shielding member 6 reaches the floor surface to block up the clearance. When the door 1 is opened, it is returned by the spring of the torsion spring.

摘要： PROBLEM TO BE SOLVED: To facilitate formation molding or the like to enhance workability by pushing a thermoplastic synthetic resin pipe into an intermediate cylinder so as to cover a middle cylinder and sending steam from many holes provided on the surfaces of the intermediate cylinder and the middle cylinder to remove the bending habit of the pipe or to form a curved surface. SOLUTION: A safety valve and a water supply port are provided on the upper surface of a steam generation tank and a hot water level meter is further provided to the side surface while a drain pipe is provided to the bottom surface thereof and, by providing a heat generator to the bottom part of this steam generation tank, steam is generated. A thermoplastic synthetic resin pipe 6 to be shaped is pushed in an intermediate cylinder 2 so as to cover a middle cylinder 1 and steam is introduced into a conduit 4 from the steam generation tank. The steam introduced into the space formed by the middle cylinder 1, the intermediate cylinder 2 and an outer cylinder 3 is ejected from many holes 5 provided to the surfaces of the middle cylinder 1 and the intermediate cylinder 2 to heat and soften the thermoplastic synthetic resin pipe 6. The pipe is cooled after the bending habit thereof is removed.

摘要： PROBLEM TO BE SOLVED: To use a simple lifter even in an unstable arranging place or an installing place such as a work site by driving a suspending medium to raise and lower a lifter, and turning the lifter by a turning device. SOLUTION: A column 3 for a lifter is erected on and fixed to an erected member 1 arranged at a work site by using plural support bodies 2. A lifter 4 is arranged on the column 3 for a lifter through a moving frame member so as to be raised and lowered and freely turned, and the lifter 4 is raised and lowered by winding or rewinding a suspending medium by driving a driving device 9. In a condition where the lifter 4 is stopped at a prescribed position of the erected member 1 and the column 3 for a lifter, the lifter 4 is turned in the horizontal direction by actuating a turning device 8, and is stopped by using a stopper or the like. Therefore, an article placed on the lifter 4 is carried in the erected member 1 in a prescribed position by using an ascent-descent and turning of the lifter 4.
