Abstract: PURPOSE:To prevent the contamination of a glass preform for optical fibers from a furnace core tube by regulating the concn. of O2 in a mixed atmosphere composed of SiF4 and an inert gas to a specific value or below at the time of producing the preform with a stage for subjecting SiO2 glass particle body to a heating treatment in the above-mentioned atmosphere. CONSTITUTION:The SiO2 glass particle body 1 produced by a flame hydrolysis method or sol-gel method, etc., is put into the furnace core tube 22 and is dehydrated by the heating treatment in a gaseous chlorine system. The gaseous mixture composed of SiF4 and an inert gas (e.g.; He) is then introduced into the furnace core tube 22 to form the mixed atmosphere composed of SiF4 and the inert gas in order to add fluorine. Further, the concn. of O2 in the atmosphere is regulated to, <1ppm by a method of providing a top cap purging part 25 in the part to be inserted with a seed rod 11 of the flange of the furnace core tube 22 to constitute an N2 purging structure, etc. The body 1 is then heated by a heater 21, by which the glass preform for the optical fibers added with fluorine is obtd.

Title: Golf club and manufacture
Inventor: TAKEBAYASHI TAKAMITSU
IPC: A63B53/02
Filed: 1988-12-23
Abstract: PURPOSE:To stabilize the flying direction of a ball by reducing the rotation of a club shaft on a rotary axis as a center during a swing from address to impact. CONSTITUTION:When a club shaft 14 is horizontally held freely rotatably in an axial direction, the rotation of the club shaft 14 is stopped in a condition that the center of gravity for a club head 10 is made stable. By manufacturing the club head based on such a condition that the center of gravity is made stable, it is reduced that the club shaft is affected by the center of gravity in the club head 10 and rotated with the shaft as the center at the time of the swing. Then, at the time of the impact, the club head hits the ball in a correct direction. Thus, when the golf club is manufactured based on a central angle with the gravity stop state of the club head 10 as reference, it can be evaded that the club is rotated in hands by an influence of the center of gravity in the club head 10 at the time of the swing. Accordingly, hook or slices, which is caused by the golf club, can be prevented.

Title: Watertight construction for unit type curtain wall
Inventor: HONDA TETSUYA
IPC: E04B2/90
Filed: 1993-12-22
Abstract: PURPOSE:To improve the watertightness of the intersecting section of curtain wall units and keep the constant pressure space of each unit at uniform level equal to the atmospheric pressure. CONSTITUTION:A curtain wall unit 1 formed out of jambs 2 and 3, a head 4 and a sill 5 is fitted with a seal material 12 continuous to the jambs 2 and 3 and the sill 5.
