A filter for flitrating molten resin of the invention includes: a cylindrical filtering member formed with a large number of projections and recesses; and radially arranged rods in a supporter for supporting the cylindrical filtering member at arc-shaped projected portions, and is constructed such that molten resin material is allowed to pass through the filtering member at arc-shaped recessed portions. In this arrangement, it is possible to enhance the resistance of thermoplastic molten resin filter against filtering pressure as well as to ensure a large filtering area. Further, the filter may be constructed such that the cross-section of the aforementioned cylindrical member is made greater from the upstream side toward the downstream side. By this configuration, the flow rate of molten resin passing through the unit area of the filtering member is made uniform and consequently the collecting capacity of foreign substances is increased.

A shape memory film formed from a shape memory transparent polymer, said shape memory film being capable of remembering a basic shape such as plane configuration and dead folds, taking on a second shape when the basic shape is modified (by changing the plane configuration and adding dead folds, twists, three-dimensional configurations, etc.) at a temperature higher than the glass transition point of the polymer and lower than the molding temperature of the polymer, and having the second shape set when cooled to a temperature lower than the glass transition point while being kept in the second shape; and a method of using said shape memory film by setting the second shape and subsequently heating the film to a temperature higher than the glass transition point, thereby causing the film to restore its basic shape.

A shape memory polymer foam which takes on a deformed shape and an as-molded shaped, said deformed shape being produced when the polymer foam is compressed at a temperature higher than the glass transition point (Tg) of the polymer and then kept compressed at a temperature lower than the Tg until compression sets, said as-molded shape being produced when the compressed polymer foam is heated again to a temperature higher than the Tg until it recovers its original shape.

A steel tube working apparatus is composed of a clamping device consisting of a pair of clamps, a pair of projecting plates, means for actuating the clamps and the projecting plates, a pair of guide bars and a main body frame; a base plate having a pair of guide rollers fitting to the guide bars fixedly secured to its opposite ends; and working means connected to the base plate in a movable and rotatable manner. A cutting device, a beveling device, a welding device, etc. are selectively connected to the base plate as the working means.

An automatic weld line following method for use with an arc welding method of welding a work by feeding a consumable electrode toward the weld line of the work through the tip of a welding torch and by oscillating the welding torch. The average and effective values of a welding current are detected, even if they are different, and fed to a computer so that the distance between the tip and the work is automatically controlled. At the same time, the oscillation angle is controlled to be symmetric at all times with respect to the weld line.
