Abstract: After it is tightened with a snug torque TA, a bolt is tuned by a total turning angle ?S equivalent to the sum of an initial-set turning angle ?A and a corrective additional-turning angle (?B+?C). The corrective additional-turning angle (?B+?C) is the sum of a first corrective additional-turning angle ?B and a second corrective additional-turning angle ?C, the first corrective additional-turning angle ?B being to compensate for a situation where a bolt turning angle ?22 corresponding to the snug torque ?A on an extension line of the bolt tightening torque properties C2 in a late tightening stage II is different from a bolt turning angle ?11 corresponding to the actual snug torque TA, the second corrective additional-turning angle ?C being to compensate for a decrease of an effective bolt axial force that is caused by an existence of the initial tightening stage I.

The method of surface treatment for a fishing tackle part made of alloy steel containing chrome according to the present invention is characterized in that the surface of the fishing tackle part made of alloy steel containing chrome is nitrided to form a diffused layer of chromium nitride from the surface of said part inwards, and then said surface is covered with a layer of titanium nitride.

Abstract: A pump for lubricating oil is mounted on the outer face of the end wall of an internal combustion engine. An oil filter is mounted on a side wall of the engine parallel to the crankshaft, and a substantially straight sub-gallery in the side wall connects the oil pump to the oil filter. A substantially main gallery receives lubricating oil from the oil filter and delivers it to branched oil supply passages to lubricate parts of the engine.

Abstract: A blow-by gas recovering system for an internal combustion engine has two blow-by gas outlets spaced longitudinally of the crankshaft and each communicating with the crank chamber. Both outlets also communicate with a chamber for separating blow-by gas from lubricating oil. Blow by gas from the separating chamber is introduced into the engine intake system.
