Abstract: A component for a gas turbine engine includes an airfoil. A first trunnion has an outer surface and extends from a first end of the airfoil. A first bushing at least partially surrounds the outer surface. At least one of the first bushing or the first trunnion includes a plurality of surface irregularities.

Abstract: An earphone cable structure includes a first connection sleeve, a primary cable, a first branch cable, a second branch cable and a thin-type bridging section. The first connection sleeve includes a first end and a second end. The primary cable is connected to the first end, and includes first core lines and second core lines. The first branch cable is connected to the second end, and includes third core lines connected to the first core lines. The second branch cable is connected to the second end, and includes fourth core lines connected to the second core lines. The axial cross-sectional width of the primary cable is equal to the axial cross-sectional width of the first branch cable plus that of the second branch cable. The thin-type bridging section is connected between the first branch cable and the second branch cable.

Abstract: A shaft bearing assembly, particularly for a miniature electric motor. In the case of the present shaft bearing assembly, an oil-impregnated dampening disc made of an absorbent material the capillary action of which is greater than that of the porous bearing block is disposed between the thrust collar of the shaft and the axial end face of the bearing block. The shaft bearing assembly is particularly suitable for electric motors of smaller size and is effective in reducing motor noise.

Abstract: A turbine flowmeter comprises an impeller which has a rotary shaft rotatable together with the impeller and is provided within a flow passage through which a fluid to be measured flows, a pair of bearing members for axially supporting the rotary shaft, an oil accumulating part for holding a lubricating oil therein, and an oil supplying part for supplying the lubricating oil in the oil accomulating part in small quantities to at least one of the bearing members. The oil supplying part comprises a capilary member.

Abstract: Friction drag washers for the drag assemblies of fishing reels are provided. The washers are made of a phenolic fiber material which is impregnated under vacuum with oil or an oil and STP oil additive solution. The viscosity of the oil can be changed to accommodate the general conditions of intended use of the reel (i.e. high drag setting--high speed withdrawal--low viscosity oil). The impregnation of the washer affords a self-lubricating lifetime washer which does not need to be changed during the life of the reel. The impregnated washers are easier and quicker to install since they do not need to be greased as they are installed.

Abstract: A wheel plate of a coupler for coupling a tractor and a trailer. The wheel plate has a lubricating arrangement for lubricating the sliding surfaces in the coupling. The lubricating arrangement includes a main groove formed in a central portion of the sliding surface of the wheel plate and surrounding the pivot shaft of the coupler, and a plurality of convolution grooves formed in the sliding surface of the wheel plate along convolution curves starting from and surrounding the main groove. The convolution grooves are communicated at their both ends with the main groove.
