Title: Production of glass material having refractive index distribution in radius direction
Inventor: MATSUO MASATAKE
IPC: C03B8/02
Filed: 1986-03-11
Abstract: PURPOSE:To obtain the titled glass having a refractive index distribution symmetric with respect to column, by producing wet gel from plural metallic alkoxide raw materials, leaching the gel without bringing the side of the gel into contact with a container of a leaching solution, drying and sintering. CONSTITUTION:Wet gel is produced from two or more metallic alkoxides such as Si(OCH3)4, Ge(OC2H5)4, etc., as a raw material. Then, the wet gel is stood in a leaching solution and leached without bringing the side of the wet gel into contact with a container of the leaching solution. Consequently, components to change refractive index are removed from the wet gel to produce wet gel having distribution of composition in radius direction. Then, the wet gel is dried and sintered to give the aimed glass material having refractive index distribution in radius direction. The glass material is preferably used as preform for optical fiber for light communication.

When adequate ventilation is attained, the detecting performance of the detector circuit 22 is ceased, and the relay 21 becomes inactive, then ''b'' conact 24 is made on and the rotation of the motor 7 is reversed through a close relay 10 and a contact 14 to close the roof window. A manual operation is also facilitated whereby the window is opened by moving a manual switch 8 to A side and closed by moving it to B side. By this constitution, the roof window is automatically opened and closed depending on the purity of the air inside the car.
