A metal filmis disposed between a permanent magnetand a rotor yoke, and the permanent magnetand the rotor yokeare subjected to beam welding. Since the metal filmis disposed between the permanent magnetand rotor yoke, and the metal filmas a laser beam irradiated portion is melted by vacuum beam or laser beam, the metal filmhas brazing metal function in welding, so that the connection between the permanent magnetand the rotor yokeis strong. Since there is no need of embedding the permanent magnetin the rotor yokeand there is no need to use polymer adhesives, the cost can be reduced.

A system for processing fuel vapor includes a fuel tank having a pressure gauge, a gas separation membrane module having a gas separation membrane for separating fuel vapor into condensed fuel vapor and fuel lean vapor, a fuel-vapor dissolution device for introducing condensed fuel vapor discharged into the fuel tank and dissolving this condensed fuel vapor in fuel, a canister having an adsorption part adsorbing fuel vapor in fuel lean vapor and a desorption device desorbing fuel vapor from the adsorption part, and an ECU programmed to, when the internal pressure of the fuel tank detected by the pressure gauge is at least a predetermined value, drive the pump to actuate the system so as to process fuel vapor. An objective of the present invention is to provide a fuel-vapor processing system that can process fuel vapor even during periods when the engine is stopped and does not require separation of fuel vapor at multiple stages, complicated control of the flow rate of fuel vapor and the flow rate of permeated gas, or liquefaction of fuel vapor.

Material for a connecting rod for an internal combustion engine is carburized and quenched, a carburized layer formed on the bearing portion is ground until the portion which exhibits the maximum compressive residual stress, and a shot-peening processing is performed on the ground surface. The invention produces a bearing portion having surface characteristics in which maximum compressive residual stress is imparted, and therefore, remarkable improvement in the fatigue strength in the bearing portion can be obtained. Furthermore, a large number of concavities formed by the shot-peening processing can be efficiently employed as an oil reservoir, so that sliding properties and lubrication can be improved, and the occurrence of problems such as fretting corrosion, galling, and seize can also be solved, and the galling and problems of the seize can be prevented.
