摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing a concave meniscus glass lens having excellent figure tolrtance. SOLUTION: In the concave meniscus lens manufacturing method which includes a press molding process of a heated and softened glass base material by a molding die, the heated glass base material is supplied between the molding surfaces of the preheated upper and lower dies and molded.

When one of the surfaces of the resultant interim lens has weakness, the temperature of the glass base material, the temperature of the upper and/or the lower dies and the cooling rate of the upper and/or the lower dies are corrected to mold a corrected lens. The press molding of the interim lens is performed by a 1st pressure and a 2nd pressure and when one surface of the interim lens has weakness, the load of the 2nd pressure is corrected to form the corrected lens. The correction is repeated until the weakness of the corrected resultant lens gets to an allowable range. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide an effective production method of a glass optical element. SOLUTION: The production method of the glass optical element is composed of a feeding step wherein a glass raw material to be molded is dropped from the top on a molding surface of a lower mold of a mold consisting of an upper mold and the lower mold. The glass raw material to be molded melted by heating, is transported on the molding surface of the lower mold. The glass raw material to be molded is dropped on the molding surface of the lower mold, by putting a guide means having a through-hole, between a position for transporting the glass raw material to be molded and the lower mold, wherein a dropping path of the glass raw material to be molded is formed before or after transporting said above, or simultaneously as transporting. Instantly after being dropped, the glass raw material to be molded is press-molded by moving the guide means back from the top of the lower mold. Also, the glass raw material having a viscosity of 10 5.5 -10 8 poise is press-molded with the mold having a temperature where this glass raw material to be molded shows the viscosity of 10 8 -10 10.5 poise (wherein, the temperature of the glass raw material to be molded is higher than the temperature of the mold).

摘要： PROBLEM TO BE SOLVED: To provide a method of press-molding an optical glass by which releasing of a glass from a mold is excellently performed.
SOLUTION: In the method of manufacturing a glass optical device by press-molding a glass base material G with a mold 10 composed of an upper die 11 and a lower die 12 respectively having molding surfaces opposed to each other, a mold having a roughened surface formed on a region except an optical function-forming region at least on the molding surface of the upper die among the upper die and the lower die is used and is preheated. The preheated glass base material is supplied to the mold and pressed under a prescribed pressure using the mold to transfer the ruggedness corresponding to the ruggedness of the roughened surface provided at least on the upper die molding surface to the glass surface. Next, the mold and the glass are cooled to cause the deviation in positions between the ruggedness on the roughened surface and the ruggedness transferred to the glass by the difference of the linear expansion coefficient between the mold and the glass so that the ruggedness of the glass runs on the ruggedness of the mold. The glass is then taken out by separating the upper die and the lower die from each other.

摘要： PROBLEM TO BE SOLVED: To provide a mold press-forming apparatus in which a press means for applying load to a press-forming die is improved and press forming can be performed without deteriorating eccentricity precision, and also to provide a press head therefor and a method for production of an optical device. SOLUTION: When pressing by a press-forming die 1, a barrel mold 4 is press-contacted with a receiving face 23 of a flange 22 of a lower die 2 by a first press head 11 to mutually position the barrel mold 4 and the lower die 2. While holding such a state, a forming material W is press-formed by adding load to an upper die 3. Thus, when press-forming the material W, the barrel mold 4 and the lower die 2 are fixed without tilting, and the first press head 11 related to the above press contact is also fixed. Thereby, the upper die 3 is pressed without tilting by a guided second press head 12, and the relative tilt of the upper and lower dies can surely be prevented from occurring, thus enabling the production of an optical device having high shape accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a device and a method for production capable of surely and stably demolding an optical element requiring a very high molding precision, after molding, by keeping the precision. SOLUTION: A device for press molding is provided with upper and lower molds having molding faces facing each other and capable of moving away from and getting closer to each other, and with a sleeve to control the upper and lower molds so as to make the axis of the upper mold collinear with that of the lower mold while it encloses the periphery of the molding faces of the upper and lower molds, when they get closer to each other. The upper or lower mold is provided on the periphery of the molding face with a guide part controlled by coming into contact with the sleeve when the upper and lower molds get closer and a non-guide part not coming into contact with the sleeve. Thereby, the device is equipped with a forced demolding means coming close to the molding face by coming near to the non-guide part when the upper and lower molds move away from each other after the press molding and demolding a press molding by coming into contact with at least a part of the periphery of the molding protruding from the non-guide part. The method for producing the press molding comprises steps of feeding a molding raw material to the press molding device, and press-molding the heated and softened molding raw material.
