20090214759	SOLUTION TREATMENT APPARATUS AND SOLUTION TREATMENT METHOD - In the present invention, a plurality of exhaust paths connected to a plurality of cup bodies surrounding substrate holding portions respectively are joined together for common use, and the openings of exhaust rate adjustment sections provided on the exhaust paths are adjusted with reference to data in which combinations of the numbers of rotations of the substrate holding portions are associated with combinations of set exhaust rates of the exhaust paths when solution treatment is performed by rotating the substrate by the substrate holding portion. According to the present invention, the cup body can be exhausted at an intended exhaust rate at all times independently of the state where the substrate in which cup body is subjected to which process.	08-27-2009

20090159728	FUEL INJECTION VALVE FOR INTERNAL COMBUSTION ENGINE - A fuel injection valve has a valve guide, a valve member movable in a center opening of the valve guide along an axial direction of the valve guide, and a covering layer disposed on a surface of the valve guide. The valve guide has a valve seat placed on an inner surface thereof and a nozzle hole from which fuel is injected. The valve member is seated on the valve seat to close the nozzle hole and leaves the valve seat to open the nozzle hole. The covering layer is placed around an outlet opening of the nozzle hole. The covering layer is made of boron nitride in a hexagonal crystal system so as to have a hydrophilic property higher than that of the surface of the valve guide.	06-25-2009

20090108102	INJECTOR - An injector includes a valve body, a needle valve, and a thermal expansion member. The valve body includes an internal space and a bottom portion having a nozzle hole. One end side of the space is covered with the bottom portion. The needle valve is accommodated in the space such that a fuel passage leading to the hole is formed between an inner surface of the valve body and an outer surface of the needle valve. The passage is opened or closed with respect to the hole by movement of the needle valve, so fuel injection is started or stopped. The inner surface of the bottom portion is opposed to a one end surface of the needle valve. The member is attached on the one end surface. The member is made of a material having a larger coefficient of thermal expansion than a material of the needle valve.	04-30-2009
