摘要： PROBLEM TO BE SOLVED: To efficiently manufacture a high quality glass substrate for a storage medium by press-forming. SOLUTION: In succession to a process for heating and press forming a glass workpiece 8 while arranging the glass workpiece 8 between an upper mold 1a and a lower mold 1b, water-cooling jackets 3a, 3b are brought into contact with the upper mold 1a and the lower mold 1b, respectively, so as to cool. The atmosphere in a chamber 18 including the molds 1a, 1b and the glass workpiece 8 is kept vacuum during heating to press-forming, and when the press-forming is finished, the chamber 18 is filled with an inert gas, and the inside of the chamber 18 is made to be atmospheric pressure. Thereafter, the cooling process is performed. COPYRIGHT: (C)2004,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method for fabricating a molding tool which is capable of molding an optical element from eco-glass at a high temperature without generating an adverse surface chemical effect in the molded element.
SOLUTION: A method for fabricating the molding tool 120 used for a mold glass optical element is disclosed. This method includes the steps of regulating the figure of the molding tool 120 to have a predetermined mold surface 122, then applying an attenuating coating 124 to the predetermined mold surface 122 and removing the attenuating coating 124 while leaving the predetermined mold surface 122 with metal ions implanted therein. The optical element can be molded from eco-glass such as titania at a high temperature without generating adverse surface chemical effect in the molded element by using the molding tool 120 fabricated by this fabrication method.

摘要： PROBLEM TO BE SOLVED: To provide a method for regenerating a forming mold for an optical element, capable of removing a metal cut and processed layer formed on a transfer surface of the forming mold without damaging the base material of the forming mold, and also to provide the forming mold for optical element.
SOLUTION: The forming mold 1, made of a super hard base material, having the transfer surface on which a covering layer 2 comprising the metal cutting and processing layer, an intermediate layer, and a surface layer is formed, is put into a heating furnace 3 with the transfer surface turning downward. The forming mold is heated at a temperature, which is not lower than the melting point of the metal cutting and processing layer but lower than the softening point of the super hard base material. Since the metal cutting and processing layer is liquefied and is flowed down, the metal cutting and processing layer, the intermediate layer, and the surface layer are removed from the super hard base material 1. A metal layer, having a melting point higher than the forming temperature of a melting point mold but lower than the melting point of the metal cutting and processing layer, may be formed between the super hard base material 1 and the metal cutting and processing layer.
