As a lubricant present between a transfer belt for transferring a print sheet and a platen plate on a rear side thereof and bringing the both into close contact, a lubricant containing 70 weight % or more of a fatty acid ester solvent with carbon number in a molecule of 20 or more and 34 or less is used so as to reduce sliding between the transfer belt and the platen plate and sliding resistance generated between the transfer belt for transferring the print sheet and an auxiliary plate arranged along this.

The present invention provides a cutting method comprising a cutting step of cutting a workpiece material with a cutting tool to thereby form a through-groove in the workpiece material, wherein in the cutting step, the through-groove is formed in the workpiece material by cutting the workpiece material with the cutting tool while contacting a cut-assisting lubricant with the contact portion of the cutting tool with the workpiece material and/or the contact portion of the workpiece material with the cutting tool, and the workpiece material comprises a fiber reinforced composite material.

The present invention provides a foamable cleaning agent for an air intake system, comprising: a) 6 to 10 wt. % of ?-sulfo-fatty acid methyl ester salt and/or alpha-olefin sulfonate; b) 6 to 10 wt. % of alkyl polyglucoside APG2000; c) 1.5 to 2.5 wt. % of coconut oil fatty acid diethanolamide and/or lauric diethanol amide LDEA; and d) 5 to 15 wt. % of water; based on the total weight of the foamable cleaning agent, also provided are an aerosol product comprising: an aerosol can containing the foamable cleaning agent, and a spraying device, through which the foamable cleaning agent can be sprayed out as a foam; and a method for preparing the aerosol product, a method of cleaning air intake system with the aerosol product, and a use of the foamable cleaning agent or the aerosol product for cleaning air intake system.

A multiphase composite lubricant for a railway lubricant stick that can be used in both low and high temperature applications. The composition of the multiphase composite lubricant includes an amount of a lubricant, an amount of a thermoplastic lattice components that forms a lattice structure, and a polymer extender.

The present invention relates to the use of organometallic salt compositions as lubricant additives and/or lubricant additive compositions to alleviate the formation of white etching cracks (WEC).

Provided is a defoaming agent showing an excellent defoaming property. Specifically, the defoaming agent includes a polymer containing as a polymerization component a polymerizable monomer (1) having a urethane bond and a fluorine-containing functional group and/or a silicone chain-containing functional group.

Implementations of the disclosed subject matter provide a lubricating oil composition. The composition comprising (a) from 45 to 75 mass % of a low viscosity first base oil component which is a Fischer-Tropsch derived base oil with a kinematic viscosity at 100 C. in the range of from 3.5 to 7.0 mm.sup.2/s; (b) from 3 to 35 mass % of a high viscosity second base oil component which is a polyalkylene glycol; and (c) an anti-foam additive which is a non-ionic surfactant. The mass % of the composition is based on the overall mass of the lubricating composition.

A sliding member has a sliding surface sliding under a wet condition in which a lubricant oil exists. The sliding surface is coated with a laminate film comprising an upper layer and a lower layer. The lower layer comprises hydrogen-free amorphous carbon (hydrogen-free DLC) and carbon particles dispersed on or in the hydrogen-free DLC. The hydrogen-free DLC has a hydrogen content of 5 atom % or less when the lower layer as a whole is 100 atom %. The upper layer comprises boron-containing amorphous carbon (B-DLC) and has protrusions on a surface side of the upper layer along the carbon particles of the lower layer. The B-DLC has a boron content of 1-40 atom % when the upper layer as a whole is 100 atom %. The protrusions have a particle diameter of 0.5-5 m and exist with a density of 20 protrusions/100 m.sup.2 or more.

The present invention relates to a lubricating agent for mounting or releasing a tire bead, comprising alkaline electrolyzed water and a lubricant component. The lubricant component comprises a lubricant base oil, which is made up of a mineral oil and/or a synthetic oil, and a surfactant. The present invention relates to a method for producing a lubricating agent for mounting or releasing a tire bead, the method comprising: mixing an alkaline electrolyzed water with a lubricant component. A tire and wheel assembly method, comprising: applying the above lubricating agent onto a contact surface of the wheel with a tire bead, and thereafter assembling the tire onto the wheel having had the lubricating agent applied thereon. A method for dismantling a tire and wheel integrated together, comprising: causing the above lubricating agent to seep onto a part of a contact surface of a wheel and a tire bead, and thereafter releasing the tire from the wheel. The provided is a lubricating agent for mounting or releasing a tire bead allows mounting a tire easily onto a wheel, at a bead seating pressure of 300 kPa or less; leaves little residual component after mounting; and enables easy releasing of a tire from a wheel. The present invention provides a tire and wheel assembly method and dismantling method in which the lubricating agent for mounting or releasing tire beads is utilized.
