  • Publication number: 20080209950
    Abstract: A processing method for glass substrate of the present invention includes: applying heat and external force to a glass substrate and then cooling it down to thereby form a compression stressed part having a different etching rate from that of other parts with respect to an etching reagent to be used, on the surface of the glass substrate and in the vicinity thereof; and performing chemical etching using the etching reagent on the glass substrate having the compression stressed part formed thereon, so as to form a relief on the surface of the glass substrate.

  • Patent number: 7407889
    Abstract: The present invention improves a method of forming a surface unevenness using a difference in etching rates, and relaxes limitations on substrates in this method. In a method of the present invention, an uneven surface is formed by a method including applying pressure to a predetermined region in a surface of a thin film formed on a substrate, and etching a region including at least a portion of the predetermined region and at least a portion of the reminder of the surface that excludes the predetermined region. An etching rate difference within the thin film increases freedom in selecting a substrate material.

  • Publication number: 20070138130
    Abstract: The present invention provides a glass substrate having a minute texture being provided on the surface and having good acid durability with high protrusion forming efficiency. According to the present invention, unevenness is formed on the surface by pressing a predetermined area of the surface of the glass substrate containing at least one oxide selected from the group consisting of SiO2, B2O3, P2O5, GeO2, As2O5, ZrO2, TiO2, SnO2, A2O3, MgO, and BeO and having a composition wherein the content of this at least one oxide is above 90 mol %, and subsequently by etching an area including this predetermined area. In the composition of this glass substrate, the ratio of oxides of network formers or intermediates is high, so that the glass substrate becomes easy to be compressed. This enables to obtain high protrusion forming efficiency even when selective leaching of a component easily leached into etchant is not employed, thereby satisfying acid durability as well.

  • Patent number: 5255759
    Abstract: An apparatus for preventing a vibration of an elevator tail-line having one stationarily held end and an opposite end connected to an elevator carriage to move together therewith. An absorber absorbs the vibration of the elevator tail-line, and a supporter bears a weight of the elevator tail-line to prevent the weight of the elevator tail-line from being applied to the absorber so that the absorber does not bear the weight of the elevator tail-line.
