An artificial stem for femur of coxa in a human body comprises a stem element, a head and a neck connecting the both, each side surface of the stem element corresponding to the indise or outside of a human body being formed by a specific curved or straight line respectively, the cross section of the stem element having a specific shape, and scale-like step patterns being formed on both the front and back surfaces, thereby improving the fitness to the femur of a small body person like Japanese, the stability and the anti-twisting strength after insertion.

A method of fabricating a piston for use in an automobile by welding. The head section and the skirt section of the piston are separately fabricated by casting such that these sections form the top wall portion of the piston when joined together and that the abutting surfaces of these sections form a portion of an oil circulating passage. Then, these sections are connected and welded together using an electron beam.
