摘要： An object of the present invention is to provide a ring segment of a gas turbine in which the temperature is maintained low, damage due to high temperature oxidation is prevented, and high temperature deformation is prevented. In order to achieve the object, the present invention provides a ring segment of a gas turbine which comprises a blade ring, a main shaft and moving blades comprising a plurality of individual units which define an annular form by being arranged around the peripheral direction of the main shaft, and disposed so that its inner peripheral surface is maintained at a constant distance from the tips of the moving blades, wherein grooves which extend along the axial direction of the main shaft of the turbine are formed upon of the individual units so as mutually to confront one another; a seal plate which is inserted into each mutually confronting pair of the grooves so as to connect together the adjacent pair of individual units; and contact surfaces which are formed at positions more radially inward than the seal plates, which extend in the axial direction and the peripheral direction and which mutually contact one another.

摘要： Provided is a metal working oil composition not containing a chlorine compound. Its working capabilities in low-speed cutting or heavy cutting operations such as broaching or gun-drilling operations are comparable to or better than those of chlorine compound-containing lubricant oil. The composition comprises 100 parts by weight of a lubricant base oil that comprises from 0 to 30% by weight of (a) a mineral base oil and from 70% to 100% by weight of (b) a &pgr; electron-containing synthetic base oil, from 0.1 to 25 parts by weight of (c) a sulfur-containing extreme-pressure agent, and from 0.1 to 7 parts by weight of (d) an alkali metal and/or alkaline earth metal sulfonate.
