摘要： The present invention relates to low-dispersion optical glass having a low glass-transition temperature suited to precision press molding, a press molding preform comprised of this glass, a method of manufacturing the same, an optical element, and a method of manufacturing the same. The optical glass comprises, given as molar percentages,28 to 50 percent of P 2 O 5 ; more than 20 percent but not more than 50 percent of BaO; 1 to 20 percent MgO; a sum of Li 2 O, Na 2 O, and K 2 O exceeding 3 percent (with 0 to 25 percent of Li 2 O, greater than or equal to 0 percent and less than 10 percent of Na 2 O, and 0 to 12 percent of K 2 O); more than 0 percent but not more than 15 percent of ZnO; 0 to 25 percent of B 2 O 3 ; 0 to 5 percent of Al 2 O 3 ; 0 to 8 percent of Gd 2 O 3 ; 0 to 20 percent of CaO; 0 to 15 percent of SrO; and 0 to 1 percent of Sb 2 O 3 ; with a sum of oxide contents of P, Ba, Mg, Li, Na, K, Zn, B, Al, Gd, Ca, Sr, and Sb being greater than or equal to 98 percent. The press molding preform is comprised of the optical glass. In the method of manufacturing a press molding preform, a glass melt gob of prescribed weight is separated from a glass melt flow, and the press molding preform comprised of the optical glass is formed with the prescribed weight. In the method of manufacturing an optical element, the press molding preform or the press molding preform manufactured by the above method is heated and precision press molded.

摘要： Provided is a low-dispersion optical glass that is formed of a fluorophosphate glass in which the molar ratio of the content of O 2- to the content of P 5+ , O 2- /P 5+ , is 3.5 or more and that has an Abbe's number (ν d ) of over 70 or has an F - content of 65 anionic % or more, and the optical glass enables the suppression of the volatilization of a glass component when an optical glass formed of a fluorophosphate glass is produced or when an obtained glass in a molten state is caused to flow out to shape it into a glass shaped material, so that the variation of properties such as a refractive index, etc., involved in the fluctuations of a glass composition and the variation of quality such as the occurrence of striae can be suppressed.

摘要： Glass-forming die, such as a parsain- forming or bottle- forming die, includes a die body having a molding surface with a curved contour to form at least a portion of a glass bottle or other article to be made. The die body has one or more cooling passages inside the body wherein the cooling passages is/are non-linear (non-straight) along at least a portion of their length to improve temperature control of the die during the glass forming operation. To this end, the cooling passages are curved in a manner to generally follow the curved contour along at least a portion of the length of the curved contour, and may include heat radiating or turbulating elements in the cooling passage. The glass- forming die alternately, or in addition, can include integral cooling fins, ribs or other heat radiating element on one or more exterior regions of the die.

摘要： Un disque de stockage optique consiste en un substrat de verre (1) dans lequel sont directement estampées par estampage à chaud des pistes pilote (3) destinées à la servocommande des faisceaux lumineux focalisés. Après estampage, le substrat de verre subit une trempe thermique dans le dispositif d'estampage pour accroître sa résistance à la rupture au moyen d'un traitement thermique. Dans le but d'obtenir des pistes pilote uniformes sur toute la surface d'un disque de stockage optique, on utilise des gabarits d'estampage (35) souples dans un porte-outil souple (34), dont la courbure peut être modifiée par application d'une pression hydrostatique. Des gabarits d'estampage adéquats sont constitués de disques de silicium monocristallin à trempe superficielle, ou de disques métalliques, structurés dans des procédés photolithographiques. Les îlots d'estampage sont réalisés avec des bords biseautés pour faciliter la séparation du gabarit et du substrat de verre après refroidissement.
