Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a glass plate to stably supply a glass plate having a constant thickness, a manufacturing method of a base material for press molding made of glass, and a manufacturing method of an optical part. SOLUTION: This glass plate is continuously manufactured by continuously introducing a melt glass flow into a mold and forms into a plate in the mold and the molded glass plate is drawn out of the mold. In this method, the variation of the thickness is reduced by changing the drawing speed of the glass plate based on the change of the height of the molten glass surface introduced in the die. This glass plate is processed into the glass base material for press molding of a desired weight, or the glass base material for press molding is heated and softened and this optical glass part is manufactured via press molding.

Abstract: PROBLEM TO BE SOLVED: To obtain a thin glass substrate having high flatness without scratches by suspending or dispersing an inorg. powder in a solvent which does not produce a decomposed gas to prepare a soln., applying the prepared soln. on the surface of a sheet glass formed by down loading method, laminating the glass sheets, interposing the glass sheets between compressing plates with high flatness, and heating and slowly cooling the sheets while pressurizing. SOLUTION: The inorg. powder to be applied preferably consists of MgCO3 and/or CaCO3 and contains boron nitride. The particle size is uniform and preferably about 20 to 30 μm. The powder is uniformly applied preferably by rotating a sponge roller impregnated with a soln. in which the inorg. material is suspended along the surface of the sheet glass. The concn. of the soln. is preferably controlled to a low level so as to form a single molecular layer. Moreover, the sponge roller impregnated with water is preferably brought into contact with the sheet glass under pressure. By this flattening method of sheet glass, a succeeding polishing process can be simplified.

Abstract: PURPOSE:To prevent the damage of rollers by dividing molten glass by the front and rear surfaces of a shaped body, joining the divided flows at a bottom end and pulling the glass plate by the 2nd pull rollers, then drawing down the glass plate by the pull rollers when the width of plate increases. CONSTITUTION:The homogeneous molten glass 3 which does not contain bubbles or foreign matter is supplied to the recessed part 2a of the shaped body 2 having the broad front and rear surfaces. The molten glass 3 flows from the recessed part 2 and flows down along the front and rear surfaces 2b, 2c. The divided flows are joined at the bottom end of the shaped body 2. The glass plate is then drawn down in the state of a large lump by retreating the pull rollers 5a to 5c to retreat positions and moving the 2nd pull rollers 6 to an advance position by the signals from a restricting means. The glass plate having the prescribed thickness and width is continuously drawn down by the pull rollers 5a, to 5c when the width of the glass plate drawn down by the pull rollers 6 increases sufficiently after 3 to 4 hours and when the thick parts at both ends decreases to the extent of not coming into pressuring contact with the rollers. The 2nd pull rollers are simultaneously retreated to the retreat position to prevent the flawing of the shaped glass plate.
