Title: Head for golf club
Inventor: SODA TAKEO
IPC: A63B102/32
Filed: 1988-08-31
Abstract: PURPOSE:To provide a stable shot a flying distance of which is high by a method wherein a heavy body approximately in a annular shape is situated along the inner periphery of the side wall of the outer shell of a body of fiber-reinforced plastics and positioned in a level lower than a half the height of a face surface, and a reinforcing material is placed to the inside of the body face surface. CONSTITUTION:Since a heavy body 6 approximately in a annular shape is disposed along the inner periphery of a side wall part 2 of a head body 1, annular structure prevents deformation of the head body 1 during driving, and energy during driving is prevented from diminution due to deformation of a head. Further, since the heavy body 6 is positioned in a level lower than 1/2 the height of a face surface 3, the center of gravity of the head coincides with the central part or a position therebelow where there is high probability for a ball to collide therewith, whereby the rotation action of the head during driving is decreased and back spin exerted on a ball is reduced. Further, since a reinforcing material 7, e.g., a metal, ceramics is disposed to the inner side of the face surface 3 in a manner to make contact therewith, the face surface 3 is reinforced, and there is no need to especially increase the thickness of the face surface 3 as in a head made of FRP.

Abstract: PURPOSE:To produce a sintered member at a low cost without carrying out a sintering stage by forming a green compact in a forming stage and passing it through a steam blackening stage to form an oxide film on the green compact optionally after dewaxing and to carry out bonding and solidification. CONSTITUTION:When an iron-base sintered member is produced, iron powder 1 is mixed with a lubricant 2 in a mixing stage I and a green compact 3 of the mixture is formed in a forming stage II. The green compact 3 is then passed through a steam blackening stage III, where it is dewaxed by preheating in a preheating part (a) and treated at a low temp. in a treating part (b) by feeding steam to form an oxide film 5 on the green compact 3. The green compact 3 having the oxide film 5 is cooled in a cooling part (c) to produce a sintered member 4'. The whole surface of the green compact 3 is coated with the oxide film 5 and the particles in the surface layer are bonded together and solidified, so a sintering stage is made unnecessary to shorten producing stages. A low-cost member can be provided to a field where very high strength is not required.
