Title: Production of preform for quartz based optical fiber
Inventor: MOTOKI MASANOBU
IPC: C03B37/016
Filed: 1986-06-04
Abstract: PURPOSE:To readily obtain a high-quality preform for fibers in good yield even for a large diameter at a low cost, by gelatinizing the first sol to be a core part, gelatinizing the second sol to be a clad part, drying and sintering the resultant wet gel. CONSTITUTION:A blend solution of ethyl silicate with absolute ethyl alcohol, water and NH3 is allowed to stand and stabilized to give a fine silica particle solution (A) having 0.01-1mu average particle diameter and good dispersibility. Hydrochloric acid is added to ethyl silicate and tetraethoxygermanium in an amount to give a given amount of GeO2 is added to treat the ethyl silicate to prepare a colorless and transparent hydrolyzate solution (B) for a core. Furthermore, hydrochloric acid is added to treat ethyl silicate and give a hydrolyzate solution (C) for a clad. The first sol which is a blend solution of the solutions (A) with (B) prepared by blending to give 60.0% ratio of the fine silica particles in the solution (A) is cast into a cylindrical vessel 1 for the clad of a vessel having double cylindrical structure and gelatinized to give a gel 4. The vessel 1 is then removed to cast the second sol 2 which is a blend solution of the solutions (A) with (C) prepared by blending to give the similar ratio as described above into a cylindrical vessel 2 for the clad and gelatinized to give a gel 5. The resultant wet gel is then dried and sintered.

Title: Device for measuring friction force
Inventor: OSAKI HIROYUKI
IPC: G01L5/00
Filed: 1992-04-24
Abstract: PURPOSE:To enable measuring friction force and friction factor under the same contacting and slide-contacting velocity as of an actual videotape recorder by rotating a rotary magnetic head which slides in contact with a magnetic tape being wound to a drum, via rotating axis, and by detecting torque of the rotating axis. CONSTITUTION:When a rotating disk 3 is rotated by a driving motor 6 via a driving axis 5 to rotate a video head 2, it is just the head 2 that moves in contact with wound magnetic tape 4 to an outer surface of the drum 1 which has a propeller type mechanism. Accordingly, being compared to not-loaded condition (when the tape 4 is not wound), increment of rotating load torque generated when the tape 4 is wound, is the very one which is generated by pure friction force between the head 2 and the tape 4. So, by measuring load torque increment by the friction force using a magnetostriction type torque meter 9, the friction force between the head 2 and the tape 4 can be measured and also friction factor is obtained, too. In this way, measurement consistent to actual usage condition can be done and therewith running characteristics and so on of the tape 4 can be precisely grasped.
