Abstract: A mold which is processed by ion beam irradiation or electron beam irradiation and in which a throughput of the mold is high and a decrease in the throughput or electrostatic discharge due to charging does not occur, a method of producing the mold, and a method of producing a molded article produced using the mold. When molding a plastic resin, at least one of a cavity and a core is provided on the surface of a conductive glass substrate. A method of producing a mold for molding a plastic resin or the like includes forming at least one of a cavity and a core by irradiating an ion beam on the surface of a conductive vanadate glass substrate that contains vanadium pentoxide (V2O5) as a main component and that has an electric conductivity in the range of 1.0×10?1 to 1.0×10?8 S/cm.

Abstract: [Problems] To provide a means for preventing electric/electronic materials from losing or degrading functionality when electrically conductive glasses are used as such electric/electronic materials. [Means for Solving the Problems] An electric/electronic circuit system comprises an electrically conductive glass member and an overcurrent preventing means for preventing overcurrent through the electrically conductive glass member, both contained within the electric/electronic circuit system.

Abstract: An improved positive-working resist material capable of forming on a substrate either a positive resist pattern or a negative resist pattern. The positive-working resist material comprises a positive-working resist resin having incorporated therein one or more photochromic compounds, such as spiropyrans, triphenylmethane dyes, anils and the like. A positive or negative resist pattern having a remarkably improved definition can be obtained. The use of such a positive-working resist material in the formation of a negative resist pattern on the substrate is also disclosed.
