    摘要： A gas turbine combustor has homogenous air inflow by elimination of turbulence from the air, reducing combustion instability. A combustor 3 has, at its center, a pilot nozzle 8 and eight main nozzles 7 around the pilot nozzle 8. The air flows in around the individual nozzles 7 and 8 to the leading end of the combustor 3 so that it is used for combustion. An annular flow ring 20, having a semicirculat section, is disposed at the upstream end portion of a combustion cylinder 10, and a porous plate 50 and a surrounding rib 51 are disposed downstream of the flow ring 20. The air inflow is smoothly turned at first by the flow ring 20 and then straightened by the porous plate 50 so that the air flows without any disturbance around the individual nozzles 7 and 8 to the leading end, thereby reducing combustion instability.

    摘要： The propeller shaft arrangement which connects a transmission with a differential gear of a vehicle includes a first propeller shaft segment connected to the transmission at one end thereof and a second propeller shaft segment connected to the differential gear at one end thereof. The first and second propeller shaft segments are made of aluminum. The other end of the second propeller shaft segment is connected with one end of a steel center bearing via art universal joint. Serrations are formed at the other end of the center bearing and at the other end of the first propeller shaft segment such that the serrations of the center bearing are engaged with those of the first propeller shaft segment and a locking nut is screwed down over the engaging serrations to join the first propeller shaft segment with the center bearing. Since the center bearing is made of steel whereas most of the propeller shaft is made of aluminum, the weight of the propeller shaft is reduced while ensuring sufficient strength of the center bearing. Further, the first propeller shaft segment is connected with the center bearing by the serrations and the locking nut. Therefore, welding the aluminum shaft with the steel bearing, which is technically difficult to perform, is not necessary.

    摘要： A premixed combustion burner for a gas turbine can efficiently premix fuel and air to produce fuel gas having a uniform concentration, while reliably achieving prevention of flash back by making the flow rate of fuel gas substantially uniform. The premixed combustion burner for a gas turbine has a fuel nozzle, a burner cylinder arranged so as to surround the fuel nozzle and form an air passageway between itself and the fuel nozzle, and swirler vanes that are arranged along an axial direction of the fuel nozzle in a plurality of positions around the circumferential direction of an outer circumference surface of the fuel nozzle. The swirler vanes gradually curve from an upstream side to a downstream side to spin the air traveling within the air passageway from the upstream side to the downstream side. A cutaway section is provided in a rear edge section on an inner circumference side of the swirler vanes.

    摘要： The present invention improves putting performance of a golf putter by balancing a torsional moment of the putter head.Golf putter includes a weighting member (W) having a weight of 15 g or more that is positioned at a distance of 1 cm or more away from an upper face of a putter head (H) toward a shaft (S). The weighting member performs a function of shifting a center of gravity of the putter toward a heel thereof and shifting a center of impact of the shaft toward a putter grip (G). Thereby, the weighting member enables a better putting by preventing off-center hitting of a putting face of the putter and preventing off-direction moving of the putter head and grip (G) at the time of putting.

    摘要： A golf ball provided with elliptical dimples. A golf ball provided with non-circular dimples, configured by forming the dimples in the surface of a sphere or of a pseudosphere which consists of a polyhedron. The dimples have a non-circular shape which has a major axis having a length at least 1.2 times greater than that of the minor axis of the shape, are each composed of a pair of circular arcs, and have a depth which causes the peripheral edges of the dimples to generate turbulence. The configuration reduces the separation width at the separation boundary to a level less than that of a golf ball having circular dimples, and this decreases the drag. The polyhedron can be substantially composed of triangles, pentagons, or hexagons.
