摘要： The object of the present invention is to provide a piston ring which is free from occurrence of cracks on the nitrided layer and having enhanced abrasion resistance and fatigue strength, and to provide a process for manufacturing the piston ring. In the invention, a surface of the steel body is subjected to a two-stage nitriding treatment consisting of low-temperature nitriding and high-temperature nitriding. A white layer on the slidable surface along the inner periphery surface of a cylinder is removed, and a white layer on each of the upper and lower surfaces and the corner portions each being adjacent to the slidable surface is removed to have a thickness of not more than 5 .mu.m.

摘要： In a magnetic head, a second leg portion 10b with which a coil is not coupled is connected to a first long side 82 1 (outer-body 8). Since the sectional area (thickness) is made larger in comparison to the conventional technique, thereby the magnetic resistance becomes lower and the read/write efficiency is increased. Since the second leg portion 10b is adapted to be connected to the outer-body 8 and thereby has a great rigidity, even if any shock is applied during assembling or while in use, the second leg portion 10b is prevented from being bent or generating cracks.
