Abstract: A pin formed at front end of a rotary tool 10 made of a metal in a rod shape is inserted between an edge of a metallic member 1 and an edge of a metallic member 1?, which inserted pin is moved along the longitudinal direction of the edges while rotating the pin, thereby generating friction heat between each of the metallic members 1 and 1? and the rotary tool 10 to weld the metallic member 1 with the metallic member 1? together. The rotary tool 10 is structured by a wide shoulder 12 and a thin pin 11 formed at the front end of the shoulder 12 and being inserted between the edges of the metallic members. Here, the pin 11 is in a right-cylindrical shape, being formed into smooth curved surface on the side thereof, and having no thread groove thereon.

Abstract: In a hybrid outboard motor equipped with an internal combustion engine and electric motor as selective sources of power for driving the propeller and further provided with the first output shaft connected to the engine for transmitting its output to the propeller and the second output shaft connected to the motor for transmitting its output to the propeller, the first and second output shafts are disposed coaxially, so that the amount of space required for installing the shafts is smaller by the length of their coaxial portion relative to the prior art in which the shafts are simply connected in tandem. As a result, the size and weight of the outboard motors can be reduced, thereby enhancing its ease of operation and portability.

Abstract: An exhaust apparatus has an exhaust pipe that receives exhaust gas from an engine and a muffler attached to the exhaust pipe. The muffler has an exhaust portion that discharges exhaust gas received by the exhaust pipe. A tubular member is attached to the exhaust portion and has an exhaust inlet portion for passage therethrough of the exhaust gas discharged through the exhaust portion and an opening portion formed oppositely from the exhaust inlet portion. A filter formed from metal fibers is disposed in the tubular member to reduce an exhaust noise created by the exhaust gas. A cap member is attached to the opening portion of the tubular member and has an exhaust outlet portion that discharges the exhaust gas from the muffler.

Abstract: A projector includes an image forming device, a projection lens for projecting an image produced by the image forming device, and an external case which accommodates the image forming device and at least a part of the projection lens and has an opening through which a light emission end of the projection lens is exposed. The projection lens has a lens barrel and a plurality of lenses equipped within the lens barrel. The lens barrel has a fixed part and a movable part. A turn table for shifting the movable part of the lens barrel in the direction of the optical axis of the projection lens is provided. The direction of the rotation axis of the turn table is substantially perpendicular to the optical axis of the projection lens. The top surface of the turn table is exposed through the outer surface of the external case.
