Abstract: A device transferring system includes a first substrate support portion on which to mount a first substrate, a second substrate support portion for supporting a second substrate opposed to the first substrate, a swinging unit for regulating the position of the first substrate support portion so that a device on the first substrate makes contact with the second substrate side in parallel to the second substrate, a movable stage for supporting and moving the swinging unit, a sensor unit for sensing the condition where the device on the first substrate has made contact with the second substrate side, the sensor unit being provided between the first substrate support portion and a sensor support portion formed in the swinging unit, and a measuring unit 61 for measuring the position of stop of a motion of the first substrate due to the contact of the first substrate with the second substrate, and for measuring the moving amount of the swinging unit after the approaching motion of the first substrate is stopped.

Abstract: The invention relates to a sheet metal member having an annular peripheral wall and a method of thickening an annular peripheral wall of the member. In the invention, the thickness of the annular peripheral wall is increased to be 2 or more times or 3 or more times that of a base plate. Teeth for a timing toothed belt, a gear, or the like are cut in the annular peripheral wall which is thickened in this way. In the method of thickening an annular peripheral wall of the invention, a base plate integrally having a flange-shaped portion is held between a circular bottom pattern tool and a circular top pattern tool, the flange-shaped portion which is projected outside and the circular top pattern tool is sequentially pressed in a radially inward direction by annular forming faces of circular rollers of plural kinds, thereby thickening the flange-shaped portion, and the flange-shaped portion is then formed into a cylindrical shape which is concentric with the base plate.

Abstract: An annular excess portion is disposed, a spline forming male mold is passed through a boss of a sheet metal-made rotary member in which a root portion of the boss and a peripheral portion are previously displaced, and the boss is set to a stationary mold with being fitted into a boss fitting hole of a rotary member holding mold. Thereafter, the annular excess portion is clamped between a pressing mold and the stationary mold to be deformed into a flat shape, and the root portion of the boss is squeezed into spline forming grooves to be plastically deformed, thereby forming a boss spline. According to the configuration, increase in thickness os a sheet metal blank is avoided, the strength of the boss is ensured, and weight reduction is achieved. The production efficiency can be remarkably improved, and cutting chips are eliminated, so that adverse influence on the working environment can be avoided.

Abstract: The present invention relates to a disc-shaped material made from metal sheet, provided for the manufacture of a pulley or the like. According to the present invention, even if the metal sheet is thin and light weight, a peripheral wall of sufficient strength can be formed, by the following steps: rotating the material held between a pair of dies and pressing an outer periphery of the material by means of a forming roller, in a radially inward direction, thereby thickening axially the outer periphery of the material to be extended to both sides of a non-processed portion, thus forming the peripheral wall.
