PROBLEM TO BE SOLVED: To provide a lubrication structure capable of realizing low friction even under severe frictional conditions. SOLUTION: The lubrication structure has Ra≥0.3 μm of roughness of the friction surface comprising a metallic material and comprises a base oil which is added with a sulfur-containing organic molybdenum-based friction-adjusting agent as a surfactant.

Abstract:
PROBLEM TO BE SOLVED: To provide a charged particle beam apparatus in which a driving part has high stability and reliability by preventing a lubricant applied to a slide portion from being used up before maintenance of the apparatus. SOLUTION: The charged particle beam apparatus has the lubricant applied to the slide portion of a moving member moving in a vacuum chamber, wherein the lubricant satisfies the followings. (1) A cumulative slide time (induction time) for starting decomposition reaction of the lubricant in a depressed state is ≥140 hours. (2) Depression (critical surface pressure) which causes decomposition reaction of the lubricant is ≥0.5 GPa. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a refrigerating machine oil composition which, in a refrigerating machine using carbon dioxide as a refrigerant, satisfies required performances such as lubricity, compatibility with the refrigerant, stability to heat and hydrolysis, and low hygroscopicity in a balanced manner, by compounding an extreme-pressure agent having a higher wear resistance than a phosphoric ester. SOLUTION: The refrigerating machine oil composition for a refrigerating machine using carbon dioxide as a refrigerant includes at least one phosphorus compound other than phosphoric esters in a base oil comprising a synthetic oil.

Abstract:
PROBLEM TO BE SOLVED: To provide an additive for oils that contains neither a metal nor phosphorus and can impart both friction reducing properties and wear reducing properties to oils such as a lubricating base oil and the like and to provide a lubricating oil containing the additive for oils. SOLUTION: Use is made of an additive for oils comprising an ester represented by formula (I), wherein R 1 and R 2 each independently denotes a hydrocarbyl or the like; a and b each independently denotes an integer of 0-5; X and Y each independently denotes a sulfur atom or a single bond; W and Z each independently denotes a hydrogen atom, -NR 3 R 4 or the like, provided that both W and Z are not a hydrogen atom at the same time and in the case where either one of W and Z is a hydrogen atom, both X and Y are not a single bond at the same time; and R 3 and R 4 each independently denotes a hydrogen atom, a hydrocarbyl or the like.

Abstract:
PROBLEM TO BE SOLVED: To provide a tribochemical reaction promoting structure easily causing abrasion by giving low roughness to generate a new surface, and delicately supplying a friction adjusting agent to the new surface. SOLUTION: This tribochemical reaction promoting surface structure is provided for relatively sliding a sliding surface 10 of a first member 1 and a sliding surface 4 of a second member 3 under lubrication of added oil including the friction adjusting agent. A grating-like cyclic structure 2 having the recess-projection height and an interval of submicron order, is formed on at least one sliding surface. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide an oil additive which is free of a metallic component and phosphorus component and enables an oil such as a lubricating oil to exhibit enhanced wear-resistant characteristics and to provide a lubricating oil containing the same. SOLUTION: The oil additive used is represented by formula (I) (wherein R 1 and R 2 are each a hydrocarbyl or the like; a and b are each an integer of 0-5; X and Y are each a sulfur atom or a single bond; W and Z are each a hydrogen atom, -NR 3 R 4 , or the like, provided that W and Z cannot be simultaneously hydrogen atoms, and X and Y cannot be simultaneously single bonds when one of W and Z is a hydrogen atom; and R 3 and R 4 are each a hydrogen atom, a hydrocarbyl, or the like).
