Abstract: PROBLEM TO BE SOLVED: To obtain a composition which exhibits excellent characteristics as a diesel fuel by adding an abrasion resistance improver to a light oil fraction having a sulfur content, a nitrogen content and a total aromatic matter content each below a specified value and an atomic ratio of hydrogen to carbon above a specified value. SOLUTION: The light oil fraction used has a sulfur content of 50 ppm or lower, a nitrogen content of 5 ppm or lower, a total aromatic matter content of 15-25 mass%, and an atomic ratio of hydrogen to carbon of at least 1.90:1. To obtain such a light oil fraction, it is desirable that the liquid space velocity is 0.1-2.0 hr-1, the hydrogen/oil ratio is 200-500 l/l, the hydrogen pressure is 400-100 kg/cm2, and the value obtained by dividing the hydrogen/oil ratio by the liquid space velocity is at least 100 hr in hydrorefining a raw material oil. The raw material oil used usually comprises one having a 10% running point of 240-280 deg.C, a 50% running point of 280-320 deg.C and a 90% running point of 330-370 deg.C. The abrasion resistance improver used preferably comprises a long-chain (e.g. 12-24C) fatty acid or ester, and it is sufficient to add it in an amount of 10-500 ppm.

Title: Dynamic pressure thrust bearing
Inventor: NAKASUGI MIKIO
IPC: F16C33/10
Filed: 1984-05-07
Abstract: PURPOSE:To prevent damage at starting or stopping, as well as to maintain stabilized space of the bearing during operation, by forming at least one of the surfaces of a flat-type dynamic thrush bearing into a convex shape. CONSTITUTION:The surface of a rotating shaft 1 which faces a thrust bearing part 5 is curved into a convex shape with a height D, so that it will have a curvaturn with a radius R. Consequently, it is not necessary to machine the angle between the line of the rotating spindle and the thrust bearing surface precisely at a right angle, and stabilized space of the bearing is ensured. Furthermore, possibility for the surfaces of the bearing to come in contact with each other during rotation is reduced and the bearing is less affected by non-uniform pressure distribution of the lubricating fluid along the radius. Also, as the contact area of the bearing at starting or stopping is almost a point contact and can be neglected, generation of excessive torque scuffing can be avoided.
