Abstract: In a direct lubrication tilting pad journal bearing, a pad has an oil collection path in a groove shape. The oil collection path is formed so that an inlet may open in an opposite end surface to a rotation direction of a rotation shaft in the pad, an outlet may open in an inner circumferential surface of the pad, and the inlet and the outlet may continuously open. Further, a width dimension of the oil collection path is smaller than a width dimension of the pad, and a depth dimension from an outer circumferential surface of the rotation shaft to a bottom surface of the oil collection path is larger than a distance from the outer circumferential surface of the rotation shaft to an end of a nozzle.

Abstract: The present invention is a process for producing a polyester-polycarbonate type thermoplastic polyester elastomer in which a hard segment consisting of a polyester constructed of aromatic dicarboxylic acid, and an aliphatic or alicyclic diol, and a soft segment consisting mainly of aliphatic polycarbonate are connected, comprising at least a step of increasing the molecular weight of an aliphatic polycarbonate diol by a reaction of an aliphatic polycarbonate diol and a chain extender, and a step of reacting aliphatic polycarbonate and a polyester constructed of aromatic dicarboxylic acid and an aliphatic or alicyclic diol in the molten state.

Abstract: The present invention provides a thermoplastic polyester elastomer excellent in heat resistance, heat-aging resistance, water resistance, light resistance, low-temperature property and the like, and further excellent in block order-retaining ability, the thermoplastic polyester elastomer comprising a hard segment which comprises polyester constituted with aromatic dicarboxylic acid and aliphatic or alicyclic diol and a soft segment which comprises mainly aliphatic polycarbonate, wherein the hard segment and the soft segment being connected, and wherein when melting points of the thermoplastic polyester elastomer are obtained by measuring on a differential scanning calorimeter in three cycles in which a temperature is raised from room temperature to 300° C. at a heating rate of 20° C./min., maintained at 300° C. for 3 minutes and lowered to room temperature at a cooling rate of 100° C./min.

Abstract: The present invention relates to such a polyamide resin composition that is suitably used as a material of a gasoline tank and a material of a molded article, such as a hollow molded container including a beverage bottle, a film and a sheet. A polyamide resin that is good in heat stability upon molding and suffers less increase in filter back pressure is provided by regulating a polyamide resin composition to have a phosphorus content of from 30 to 200 ppm (excluding 200 ppm), and a sodium content/phosphorus content ratio (molar ratio) of from 3 to 7 (excluding 3 and 7) or regulating it to have a phosphorus content less than 30 ppm and an alkali metal content less than 45 ppm.
