A method for producing an aluminum-alloy shaped product, includes a step of forging a continuously cast rod of aluminum alloy serving as a forging material, in which the aluminum alloy contains Si in an amount of 10.5 to 13.5 mass %, Fe in an amount of 0.15 to 0.65 mass %, Cu in an amount of 2.5 to 5.5 mass % and Mg in an amount of 0.3 to 1.5 mass %, and heat treatment and heating steps including a step of subjecting the forging material to pre-heat treatment, a step of heating the forging material during a course of forging of the forging material and a step of subjecting a shaped product to post-heat treatment, the pre-heat treatment including treatment of maintaining the forging material at a temperature of −10 to 480° C. for two to six hours.
摘要:
A straddle-type vehicle that adequately and smoothly sucks air into an air cleaner arranged between a front wheel and a leg shield while inhibiting foreign matter from being drawn thereinto. An intake port of the air cleaner is opened rearwardly. The leg shield is formed with a recess that surrounds the air cleaner. The recess includes a round portion along a direction in which the intake 61a is opened.

A reaction column comprising a reactor, at least one catalyst bed comprising a solid catalyst with which a mixture of a gas with a liquid is brought into contact; and a cooling bed provided below the catalyst bed. The cooling bed includes a cooling fluid feed section and a mixing mechanism for mixing a cooling fluid with the mixture of a gas with a liquid falling down through the reactor. The mixing mechanism is provided below the cooling fluid feed section of the cooling bed, and includes a collector tray provided along a horizontal cross-sectional region of the reactor, a swirl baffle vertically provided substantially at the center portion of the upper surface of the collector tray, and a weir extending upward from the collector tray. The swirl baffle is formed with a cylindrical member having a central axis substantially coincident with the central axis of the collector tray. Inflow ports respectively for the cooling fluid and the mixture of a gas with a liquid are provided at a plurality of positions discrete from each other by a predetermined angle in the circumferential direction of the circumferential wall of the cylindrical member. A guide plate is connected in a substantially tangential direction to a first side edge of each of the inflow ports. The weir is connected to a through hole provided in the interior of the swirl baffle, and is formed with a cylindrical member having a central axis substantially coincident with the central axis of the collector tray. The weir preferably defines an upper mixing cap and outflow ports respectively for the cooling fluid and the mixture are provided at a plurality of positions discrete from each other by a predetermined angle in the circumferential direction of the circumferential wall of the weir.

摘要:
A straddle-type vehicle that reliably inhibits entry of fluid to a tail lamp unit. An extending member protrudes upward from a rear fender and extends in a vehicle width direction. The extending member covers a sealing member of flasher lenses and a tail lamp lens when the motorcycle is viewed from the rear. A gutter guides fluid that enters a space between the extending member and the tail lamp unit.
