    摘要: There is provided a thermal head having protective layers comprising a lower protective layer, an intermediate layer and a carbon-based protective layer which is composed of a plurality of sub-layers, wherein the carbon-based protective layer has stress values that become sequentially higher from one of the sub-layers located undermost toward another of the sub-layers located uppermost. The protective layers have significantly reduced corrosion and wear and is protected from cracking and peeling, whereupon the thermal head obtained can have sufficient durability and reliability to ensure that thermal recording of high-quality images is consistently performed over an extended period of operation.

    摘要: A method of cooling a steel pipe which can effectively suppress quenching-induced bending which occurs when quenching a thin-walled steel pipe with a wall thickness/outer diameter ratio of at most 0.07 without decreasing the manufacturing efficiency of the steel pipe comprises cooling the inner surface of the steel pipe by spraying cooling water into the interior of a horizontally-disposed steel pipe 2 while rotating the pipe in its circumferential direction, and the outer surface is cooled by producing a downward flow of cooling water streams 5a and 5b in a planar shape from above onto the outer surface along the axial direction of the steel pipe 2. Cooling of the inner surface is started at least 7 seconds before cooling of the outer surface. Cooling of the outer surface is carried out by producing downward flow in a planar shape of cooling water 5a and 5b at two locations 4a and 4b at approximately equal distances from the uppermost portion of the steel pipe 2, and the flow rate of cooling water 5a which flows down at a location on the upstream side in the rotational direction of the steel pipe 2 is made larger than the flow rate of cooling water 5b which flows down at a location on the downstream side in the rotational direction.
