Title: Film roll
Inventor: NISHIGAKI YASUO
IPC: B65H18/28
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To restrain the occurrence of creases in a rolled film during storage at a high temperature by forming a film roll to meet the condition that the circumferential length of the central part of a roll formed by winding a film round a take-up core with a width and a length equal to or larger than a specified value is larger than the average value of the circumferential lengths of both end parts of the roll. SOLUTION: A film roll is a roll formed by winding a film round a core with a width of 300 mm or more and with a length of 1000 m or more. When the circumferential length of the central part of the film roll is larger than the average value of the circumferential lengths of both end parts of the roll by 0.5 mm or more, a more remarkable effect can be obtained, and preferably 2.0 mm or more. Accordingly, it is comparatively convenient that the thickness in the cross direction in manufacturing the film is adjusted and in the width of the final film roll, the thickness of both end parts is made smaller than the thickness of the central part. To be concrete, in forming a film by fusion and extrusion through a slit die, the gap of the slit die is adjusted in the cross direction and adjusted so that the thickness of the film satisfies the described relationship at a desired width.

Inventor: MATSUMOTO TAKERU
IPC: F28F11/00
Filed: 1979-12-26
Abstract: PURPOSE: To facilitate the inspection of welded part and the after heat treatment in a pipe plate having a pipe hole which functions as a pipe and is plugged by attaching a plug tube over the pipe hole by means of welding and then attaching a plug to the plug tube by means of butt-welding.  
     CONSTITUTION: The pipe plate 1 is engraved on the upper surface with an annuar groove having a depth of (h) and a width of (e) around the pipe hole so as to form an annular projection having the same thickness t 1  as the plug tube 2 at the upper end of the pipe hole 1'. The lower end of the plug tube 2 is tapered at an angle of θ 1  toward the outer periphery. The projection is also tapered in the upper surface to meet the tapered surface of the plug tube 2. The plug tube 2 and the projection are abutted to each other and welded from the inside of the plug tube 2. The welded part is subjected to an X-ray inspection, and if necessary, an annealing is effected. Then, the plug 3b is welded to the plug tube 2. Thus, the welding operation comprises two steps so that after the first step, an inspection and after heat treatment can be effected. Accordingly, the after heat treatment of the product can be facilitated and the reliability at the welding quality is much improved.
