Abstract:
PROBLEM TO BE SOLVED: To provide a suppressing method of damage caused by arcs between electric contacts preventing damage caused by arcs between the electric contacts by applying grease to between the electric contacts. SOLUTION: The suppressing method of damage caused by arcs between the electric contacts is that grease comprising 95-70 wt.% base oil other than fluorine-base oil and 5-30 wt.% a thickening agent and an additive is applied to the electric contact making a pair of terminals installed wiring on and off by relative movement to suppress the damage in a contact region caused by the arcs generated in the shut off of the electric contact. As the thickening agent, organic material-mixed bentonite is preferable. As the base oil, ester oil, glycol oil, or poly-α-olefin are preferable. Low viscosity base oil is preferable because energy by the arc is low. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a high thermal conductivity fully thin cured product which does not stain an area outside the application area and does not exude oily matter even when used over a long time and to provide a thermally conductive silicone grease composition which gives the cured product when cured. SOLUTION: The thermally conductive silicone grease composition is one comprising 100 pts.mass (A) organopolysiloxane having at least two Si-bonded alkenyl groups in the molecule, such an amount of (B) an organohydrogenpolysiloxane having at least two Si-bonded hydrogen atoms in the molecule that 0.1 to 5.0 Si-bonded hydrogen atoms in component (B) is present per alkenyl group in component (A), 100 to 2,200 pts.mass (C) thermally conductive filler, an effective amount of (D) a platinum catalyst, and an effective amount of (E) an addition reaction inhibitor, wherein component (C) contains above 90 to 100 mass% indium powder having an average particle diameter of 0.1 to 100 μm.

Abstract:
PROBLEM TO BE SOLVED: To provide a lubricant composition, which can be used for various purposes and can reduce an electric power and fuel consumption and further increase cooling efficiency and suppress the lowering of developped output when it is used in a compressor or an internal combustion engine and the like. SOLUTION: The lubricant composition is a lubricity base oil containing the primary ultrafine powder of a metal and the secondary ultrafine powder of a mineral. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
The use of sub-micron particles (nano-particles) and carboxylates for improving the heat-exchange characteristics of heat-transfer fluids or antifreeze coolants. The carboxylates form a stable physisorbed- or chemisorbed carboxylate protective layer on metallic nano-particles that does not hinder heat-transfer. The combination of carboxylates and metallic nano-particles provide excellent corrosion protection, improved heat-transfer and enhances the stability of the sub-micron particles (nano-particles) in suspension. Sub-micron particles (nano-particles) treated with carboxylates to form a chemisorbed carboxylate protective layer are used in a heat transfer fluid or a lubricant or hydraulic fluid or soap.
