    摘要: A tappet is used in an internal combustion engine. A cam receiving plate which contacts a cam is brazed on the upper surface of a top wall of a tappet body. The whole surface of the cam receiving plate can act as a cam follower surface, thereby making the outer diameter of the cam receiving plate to the minimum size corresponding to projected length of a nose of a rotary cam and lightening the tappet.

    摘要: An Al alloy tappet used in an internal combustion engine has a spiral groove on the outer circumferential surface of a tappet body. The spiral groove is formed by pushing a cutting tool against the outer circumferential surface and feeding it in an axial direction. Near the lower end of the tappet body, feed rate is decreased, and the cutting tool is moved away from the tappet body to form a smaller spiral groove which increases in diameter downwards. The outer circumferential surface of the tappet body is covered with a coating layer such as Fe, and the lower end which has the smaller spiral groove is chamfered.

    摘要: A tappet made of Al alloy is used in a valve operating mechanism of an internal combustion engine of a vehicle. On the whole outer circumferential surface of the tappet, a helical projection and a helical groove are formed alternately to form an uneven surface. A plurality of uneven surfaces are formed on a ridge of the projection at regular intervals. The outer circumferential surface is coated with a wear resistant Fe film by thermal spraying. The uneven surfaces on the projection provide high adhesion strength of the film to the outer circumferential surface of the tappet to improve peel resistance, thereby increasing durability and reliability of the Al alloy tappet.

The apparatus includes an X--Y stage for fixing the first optical component and aligning the optical axis of the first optical component in an X-axis and Y-axis direction. A fixing disk has a plurality of apertures extending radially and intersecting one another at a center of the fixing disk with respect to the radial direction, and includes a clamp for fixing the second optical component in the center of the fixing disk with respect to the axial and radial directions thereof such that the contact surface of the second optical component faces the contact surface of the first optical component. A holding member has a plurality of apertures each formed in a position respectively corresponding to a position of one of the plurality of apertures of the fixing disk, and the holding member releasably holds the fixing disk and is adapted to carry the fixing disk for axial movement thereof in a Z-axis direction. A Z stage for moving the holding member in the Z-axis direction is provided for fitting the respective contact surfaces of the first and second optical components to each other, and laser emitting heads emit a laser beam through corresponding apertures of the fixing disk and holding member to weld the first and second optical components together at the respective fitted contact surfaces thereof, with the optical axes of the first and second optical components in alignment with each other.
