IPC: B01J2/16
Filed: 1978-09-27
Granted: 1982-04-16
Abstract: A method for granulation of sodium metasilicate containing 2-6 % moisture was described.  Thus, anhydrous silicate and metasilicate solution were induced in the first region(1) and contacted with the solid particles by injector(3).

Title: Optical waveguide soot preform
Inventor: BAILEY ALAN CURTIS
IPC: C03B37/025
Filed: 1981-07-03
Granted: 1983-10-17
Abstract: A method of making solid glass articles by the flame hydrolysis technique. A thin stratum of low viscosity glass soot is applied to the surface of a mandrel. First and second coatings of glass soot are deposited on the surface of the thin stratum to form a porous preform. The refractive index of the soot particles of the first coating is greater than that of the soot of the second coating, and the soot of the first coating has a viscosity lower than that of the second coating. The mandrel is removed, and the soot preform is subjected to a high temperature whereby it is consolidated to form a dense glass blank. The glass surface tension and the relative viscosities of the inner and outer portions of the preform cause the aperture to close during the consolidation process. The thin stratum, which preferably includes P2O5, smoothes over the damage caused by removing the mandrel and reduces or even eliminates seed formation at the axis of the resultant glass blank. The blank may be heated and drawn into a filament, or it may be sliced into optical windows, lenses or the like.

Title: Track servo system for optical disk player
Inventor: EGUCHI NAOYA
IPC: G11B7/09
Filed: 1987-12-15
Granted: 1995-07-07
Abstract: A track servo system in a recordable optical disc player utilizes clock signals produced by irradiating a laser beam (P) on clock pits (3) in servo areas as a reference signal for on-track adjustment. Based on the clock signal, the polarity of a tracking error signal is detected (20) for selectively opening and closing a servo loop (50) of the tracking servo system. CLOSED LOOP on-track adjustment is performed while a laser beam spot is in a range where the tracking error indicating value decreases as the distance of the laser beam spot from the track centre decreases. On the other hand, OPEN LOOP on-track adjustment is performed while the laser beam spot is in a range where the tracking error indicating value increases as Since the polarity of the tracking error signal indicates the range of the laser beam spot position, selection of the CLOSED LOOP and OPEN LOOP can be made without requiring the signal to be reproduced from the data area.
