Abstract:
There is provided a gradient index rod lens unit having a desired chromatic aberration. The gradient index rod lens unit is comprised of two gradient index rod lenses 11 and 12 with different chromatic aberrations and the entire lengths thereof adjusted, which are disposed in series with the optical axes thereof in alignment. The chromatic aberration of the gradient index rod lens unit can be set to a value falling within chromatic aberration ranges inherently possessed by the respective gradient index rod lenses 11 and 12.
Abstract:
An apparatus for bend-shaping a glass sheet is disclosed, which comprises a heating furnace, a plurality of in-furnace beds disposed within the heating furnace, at least one out-furnace bed disposed externally of the heating furnace proximately to an outlet of the heating furnace, and an elevating mechanism disposed below that one of the in-furnace beds which is positioned proximately to the outlet and the out-furnace bed. The in- and out-furnace beds have upper surfaces curved transversely and capable of jetting air to floatingly support a glass sheet. For producing a dual curved glass sheet, the elevating mechanism is operated to elevate opposed ends of the one in-furnace bed and the out-furnace bed so that these beds jointly form a hill. For producing a single-curved glass sheet, the elevating mechanism is operated to lower the opposed ends of those beds to their original flat positions.

There is provided an EL device which has sufficient strength to external pressure and is capable of effectively preventing moisture and oxygen from infiltrating into the EL device, thereby having a prolonged life. An organic EL device 200 is comprised of a substrate 1, an organic EL multilayer film 2 that is formed on the substrate 1, and a sealing plate 31 that is bonded onto the substrate 1 using an adhesive 4 so as to cover the organic EL multilayer film 2. The sealing plate 31 is of a flangeless type, wherein the width of peripheral projecting parts thereof is not less than the thickness at these peripheral projecting parts, and moreover is not less than 0.7 mm.
Abstract:
A high transmittance glass sheet is provided that is formed of a soda-lime-silica glass composition containing, expressed in wt. %, less than 0.020% of total iron oxide in terms of Fe2O3 and 0.006 to 2.0% of zinc oxide.

Abstract:
The present invention relates to a substrate for information recording media for use as a disk substrate in a hard disk drive or the like and a manufacturing method thereof, an information recording medium such as a magnetic disk, and a starting material glass plate for use as a starting material of the substrate for information recording media. By suitably controlling forming conditions of the starting material glass plate, the starting material glass plate can be manufactured so as to have a long-wavelength waviness of not more than 6 nm. By carrying out precision polishing on this starting material glass plate having a long-wavelength waviness of not more than 6 nm using CeO2 abrasive grains having a mean grain diameter of not less than 0.01 nullm and a 90% diameter of the volume grain size distribution of not more than 0.02 nullm, a substrate for information recording media having an excellent planarity can be obtained in a short time and with a low polishing amount. Moreover, by using this substrate for information recording media, an information recording medium able to cope with increased data zone recording density can be provided.
Abstract:
There is provided a method of manufacturing a glass substrate for magnetic disks, according to which circumferential direction texture can be formed without bringing about a drop in anisotropy, thus enabling coating with a magnetic recording layer having a large magnetic coercivity. In a texturing step, a tape is used while a diamond slurry is fed onto at least one main surface of a glass substrate member that has been processed into a substantially circular shape, thus forming a linear texture in a circumferential direction on the at least one main surface. In a chemical strengthening step, the mechanical strength of the glass substrate member is chemically strengthened to a level required of the glass substrate for magnetic disks. The texturing step is carried out after the chemical strengthening step.
Abstract:
There is provided a substrate for information recording media and a manufacturing method thereof, which allow an information recording medium to be driven reliably and stably even when the flying height is made lower than conventionally to cope with increased recording density of the data zone. Precision polishing is carried out on a glass substrate using a polishing agent. After the precision polishing, surface treatment is carried out using an etching liquid containing both hydrofluoric acid and a fluoride salt.
