摘要： An inventive automated heat treatment system has a furnace for heat treating forged engine valves, a carry-in mechanism for transporting the forged valves into the furnace, and a carry-out mechanism for transporting heat treated valves out of the furnace. Each of the carry-in mechanism and the carry-out mechanism has a retention mechanism for retaining valves hung, and a transport mechanism for transporting valves to the furnace as they are hung. The furnace has heating means, groups of paired rails for supporting and moving the valves hung in the furnace, and a stopper for controlling the positions of the valves on the rails. The engine valves are maintained hung with their umbrella-shaped portions supported by the respective mechanisms throughout the automated heat treatment processes. Thus, the heat treatment of engine valves is done in a fewer steps than in a conventional system.

摘要： A biaxially oriented polyester film which is well balanced between sliding properties and transparency and having an enhanced uniformity in thickness is prepared by a process wherein a polyester, predominantly comprised of polyethylene terephthalate, is extruded into a sheet form extrudate; the extrudate is quenched to a temperature of below Tg to obtain a solidified, substantially amorphous film; the film is drawn in the longitudinal direction at a drawing ratio of larger than 2.4 but smaller than 6.5; the film is quenched; and then, the film is drawn in the transverse direction at a drawing ratio of at least 2.5. The drawing in the longitudinal direction is carried out in two steps wherein:(i) in the first drawing step, the substantially amorphous film is drawn in one or more stages at a total drawing zone length (l.sub.1) of at least 50 mm so that the resulting polyester film possesses a birefringence of 1.times.10.sup.-3 to 12.times.10.sup.-3 ;(ii) the drawn film is kept, without being quenched to a temperature of not higher than the Tg, in contact with a roll maintained at 100.degree. to 130.degree. C.; and then,(iii) in the second drawing step, the film is drawn at a drawing ratio of larger than 1.6 but smaller than 2.7 in one stage at a drawing zone length of shorter than l.sub.1 /2.

摘要： A method of efficiently cutting and machining opposite ends of rod members in sequence is provided, which comprises steps of: abutting a grinding wheel (5) against the periphery of a long rod material (10a) placed at a predetermined work position; moving the grinding wheel towards and along the axis of a first portion of the long rod material (10a) in rotation to taper the tail end of the first portion (to be provided as a rod member); and then moving the grinding wheel (5) further towards the axis of the rod material (10a) to cut the first portion off the long rod material and at the same time chamfer the leading end of a second portion of the long rod material in contact with the rear side of the grinding wheel. After removing the first rod member cut off, the sequence of these steps is repeated as needed.
