    Abstract: PROBLEM TO BE SOLVED: To provide a reciprocating device for a moving body which can reciprocate it at a high speed without practically decelerating after turning back even if a reciprocating range is short in the reciprocating device using a thrust generating mechanism such as a linear motor mechanism. SOLUTION: A reciprocating device reciprocates a moving body 2 by arranging a linear motor mechanism 1 in parallel to a reciprocating passage 11 of the moving body 2. A stroke means 4 is arranged in a turning-back part of the reciprocating passage 11, and stroke object parts 2c composed of an elastic material are arranged on both side surfaces of the moving body 2, and a speed detecting sensor 3 of the moving body 2 is arranged on this side of the turning- back part. A control part 5 is arranged to perform an operation on the stroke timing by the stroke means 4 from entering speed of the moving body 2 detected by the sensor 3 and an apparent distance by adding a deformation quantity of the stroke object parts 2c to a distance up to the turning-back part from the sensor 3.

The non-vibration roller 6a, 6b keep and fix the opened width of the fiber bundle 2 opened by the vibration rollers 5a, 5b. The contact lengths of the vibration rollers 5a, 5b and the fiber bundle are compared and the contact length of the non-vibration rollers 6a, 6b and the fiber bundle 2 is set to 2-10 times and, as concrete length, the contact length is pref. 100mm or more.

    Abstract: PROBLEM TO BE SOLVED: To obtain a uniform and good bonded state in a laminated surface, in laminating first and second base material through a laminating material, by together using pressure due to substantially uniform surface pressure and pressure due to high surface pressure in a peripheral edge part. SOLUTION: When the operation switch 16 of a pressure laminating machine 1 is operated after a laminated product 8 is set on a receiving stand 9, air- pressure PA is supplied to the upper part of a cylinder 4 and the top plate 4 fixed to a rod 4' falls and a uniform pressure fixed form material 11 or a frame material 13 approaches the upper surface of the first base material 5 of the laminated product 8. Next moment, the peripheral edge part of the laminated product 8 is held to surface pressure higher than that of other part by a frame material 13 and lamination advances. A part other than the peripheral edge part is elastically deformed on the upper surface of the base material 5 in such a form that the fixed form material 11 conforms to the wall thickness change of a second base material and uniformly pressed in a state slightly lower than the peripheral edge part in surface pressure and lamination advances.

    Abstract: PROBLEM TO BE SOLVED: To make it possible to maintain the uniform thickness of a formed coating film by placing a member to be coated on a stage surface and sucking the peripheral parts of this member to be coated by suction holes included in the suction hole arrays corresponding thereto. SOLUTION: A glass substrate A on the stage 6 is sucked by the suction holes 74 of the suction hole arrays R up to its outer periphery edges in the formation of the coating film on the glass substrate A and, therefore, the floating of the outer periphery parts of the glass substrate A from the top of the stage does not arise. Since the suction surface 76 of the stage 6 is smooth, the glass substrate A is sucked and held in the stage that the entire surface of its rear surface is held in well tight contact with the suction surface 76 of the stage 6. Then, the clearance between the discharge port of a slit die and the glass substrate A is made uniform in forming the coating film on the glass substrate A. Consequently, the film thickness of the coating film is made uniform.
