PROBLEM TO BE SOLVED: To provide a lubricant composition which shows an extremely low friction coefficient when used as a lubricant for a low-friction slide material, and to provide a sliding mechanism excellent in low friction property and abrasion resistance by combining the lubricant composition with a sliding member having a DLC coating on a sliding surface.SOLUTION: The lubricant composition for a low-friction slide material includes an organic molybdenum compound which has a nitrogen (N) atom and/or an oxygen (O) atom, and may have a sulfur (S) atom in a molecule, wherein a sulfur content is at most 0.5 mass% by a compound basis. In addition, the sliding mechanism using the same is disclosed.

PROBLEM TO BE SOLVED: To provide a lubricant oil composition exhibiting extremely low friction coefficient when used as a lubricant oil for a low friction sliding material; to provide a sliding mechanism with excellent low friction by combining sliding members having a particular coating film for a low friction sliding material on the sliding surface using the same. SOLUTION: The lubricant oil composition used for a low friction sliding material is obtained by compounding an additive selected from a particular phosphorus-zinc-containing compound and a particular sulfur-containing compound. The sliding mechanism includes two mutually sliding members with the lubricant oil composition interposed between their sliding surfaces; wherein at least one of the two sliding members has a DLC (Diamond-Like Carbon) coating film formed on its sliding surface, the DLC coating film containing 5-50 atom% of hydrogen.

Abstract:
PROBLEM TO BE SOLVED: To provide a manufacturing device of a fuel injection valve capable of efficiently performing a coating film only in a required place. SOLUTION: A nozzle plate 6 and a valve housing 5 of a valve device 3 can be stored inside. A holding device 16 is arranged for aligning and providing a plurality of holding holes 35 and 37 oppositely opening in an anode electrode 23 of a coating film processing device. A surface 6C of the nozzle plate 6 exposed to a combustion chamber of the valve device 3 is respectively exposed to the plurality of holding holes 35 and 37 of the holding device 16 from an opening of the plurality of holding holes 35 and 37. A large number of valve devices 3 are positioned by the holding device 16. The large number of positioned valve devices 3 and its holding device 16 are arranged on a cathode electrode 25 of the coating film processing device, and a deposit-sticking preventive coating film is formed on the surface 6C of the nozzle plate 6 and an inner surface of an injection hole 6A opposed to the anode electrode 23.

Abstract:
PROBLEM TO BE SOLVED: To provide a gas barrier structure capable of improving a heat radiating property of a diaphragm rubber film of a sealed hydraulic damper, and a forming method thereof. SOLUTION: The gas barrier structure for a rubber film 10 constituting a diaphragm for a sealed hydraulic damper comprises an aluminum thin film 14 formed on the surface of the rubber film 10 and a flexible DLC film 18 formed on the aluminum thin film 14. The aluminum thin film 14 and the flexible DLC film 18 are bonded to each other by an aluminum-silicon eutectic layer 14 interposed between the films. COPYRIGHT: (C)2008,JPO&INPIT
