Title: Production of inorganic oxide
Inventor: MORIMOTO TAKESHI
IPC: C01B33/193
Filed: 1989-12-19
Abstract: PURPOSE:To prevent discoloration and reduction in strength by prewashing a molded article of inorganic oxide consisting essentially of silica produced by sol gel method with organic solvent before burning and removing carbon content to remain after burning. CONSTITUTION:Water glass is reacted with an acid or an alkali in the presence of a surfactant (e.g. polyethylene glycol) to give sol. Or a silicon alkoxide (e.g. silicon tetramethoxide or silicon tetraethoxide) is reacted with an acid or an alkali and water to give sol. Then the sol is formed to give a molded article, which is washed with an organic solvent (propyl alcohol or butyl alcohol) to remove organic substances to remain as carbides after burning. Then the washed molded article is burnt at 500-1,500 deg.C for 1-10 hours to give a molded article of silicate.

Abstract: PROBLEM TO BE SOLVED: To provide a wood-club metal head that is further excellent in the directivity of hit balls regardless of a large head volume by setting the head volume and the depth of the center of gravity at specific values. SOLUTION: This wood-club metal head is formed into a hollow shape from a single metallic material with a small specific gravity, such as titanium, with the head volume set at 220 to 320cc. The head volume is an overall volume surrounded by the outer surface of the metal head. The thickness T1 of a face 1 is increased, and the thickness T1 of the remaining part, i.e., the thickness T2 of a sole 2 and a crown 3 is reduced to set the depth D of the center of gravity at 16 to 26mm. The depth D of the center of gravity is the length of a perpendicular M extending down from the center G of gravity of the head to the face 1. When a ball is struck at a position off the sweet spot, the wood- club metal head improves the directivity of the hit ball if the club has collided flat against the ball.
