    摘要

    The ink jet recording apparatus comprises a recording head provided with a nozzle forming surface provided with nozzles which discharge an ink composition containing inorganic pigments, and a liquid repelling film which is provided on the nozzle forming surface; a maintenance unit for preserving the recording head; and a movement section which is arranged at a position which faces the nozzle forming surface and the maintenance unit and which relatively moves the nozzle forming surface and the maintenance unit.

    权利要求
    1 . A lubricating oil composition, comprising: a base oil (A); an olefin copolymer (B); and a poly(alkyl(meth)acrylate) (C), wherein a weight average molecular weight of the olefin copolymer (B) is in a range of from 10,000 to 80,000, a content of the olefin copolymer (B) is in a range of from 0.01% to 0.23% by mass, based on a total amount of the lubricating oil composition, and a content of the poly(alkyl(meth)acrylate) (C) is in a range of from 0.02% to 0.40% by mass, based on the total amount of the lubricating oil composition.
    2 . The composition of claim 1 , wherein a weight average molecular weight of the poly(alkyl(meth)acrylate) (C) is in a range of from 5,000 to 100,000.
    3 . The composition of claim 1 , wherein a ratio of the content of the olefin copolymer (B) to the content of the poly(alkyl(meth)acrylate) (C) [(B)/(C)] is in a range of from 0.2 to 6.0.
    4 . The composition of claim 1 , wherein a total content of the olefin copolymer (B) and the poly(alkyl(meth)acrylate) (C) is in a range of from 0.03% to 0.63% by mass, based on the total amount of the lubricating oil composition.
    5 . The composition of claim 1 , wherein a kinetic viscosity of the composition at 40° C. is in a range of from 6.0 to 18.0 mm 2 /s.
    6 . The composition of claim 1 , wherein a Brookefield (BF) viscosity of the composition at −40° C. is 5,000 mPa·s or more.
    7 . The composition of claim 1 , wherein a pour point of the composition is −35° C. or less.
    8 . (canceled)
    9 . A method of producing the composition of claim 1 , the method comprising blending the base oil (A) with the olefin copolymer (B) and the poly(alkyl(meth)acrylate) (C).
    10 . A device comprising the composition of claim 1 .
    11 . The device of claim 10 , which is a hydraulic system, a stationary transmission, an automotive transmission, or a cooling system.
    12 . A method of lubricating a hydraulic system, a stationary transmission, an automotive transmission, or a cooling system, the method comprising contacting the hydraulic system, the stationary transmission, the automotive transmission, or the cooling system with the composition of claim 1 .
