    摘要: Ti alloy is embedded in a powder such as graphite and heated with the powder in an oxygen atmosphere. Oxygen atoms are diffused into the Ti alloy to form an oxygen diffusion layer of Ti—O solid solution, thereby increasing wear resistance of the valve. A poppet valve in an internal combustion engine may be made of such Ti alloy.

    摘要: A poppet valve in an internal combustion engine of a vehicle consists of a valve body which comprises a valve stem and a valve head at one end of the valve stem. An oxidized layer is formed on portions of the valve body which contacts another valve-operating member. On the oxidized layer, a carburized layer is formed to cover the whole surface to increase wear resistance and fatigue strength of the valve.

    摘要: A tappet in a direct acting type valve operating mechanism of an internal combustion engine comprises a top wall and a cylindrical portion. The upper and lower surfaces of the top wall contacts a rotary cam and the end of a stem of an engine valve respectively. A hard metal layer is formed at the upper and lower surfaces of the top wall to increase strength thereof, thereby increasing wear resistance and durability of the tappet.

    摘要: The invention provides a useful vehicle dispatching system. Server 60 estimates an approximate location of a passenger on the basis of the area code transmitted from server 40. Server 60 transmits a list of landmarks located in the area corresponding to the area code, and the list is thereby provided to the passenger carrying mobile station 10. The passenger selects a desired landmark to which a vehicle should be dispatched. Server 60 determines the location of the landmark by referring to the landmark database; and determines which vehicles 20 are located proximate to the landmark by referring to the vehicle database. Server 60 transmits the information on the determined vehicles 20 to mobile station 10, and the information is thereby provided to the passenger. The passenger selects a desired vehicle 20 to make a telephone call to the driver of vehicle 20. Thus, the passenger may directly talk to the driver.
