Patent number: 6586102Abstract: Coated articles are provided with an anti-reflective (AR) layer(s) system which enables reduced reflection, increased visible transmission, and/or neutral color. In certain embodiments, the AR layer(s) system includes a silicon nitride layer(s), a silicon oxynitride layer, and/or a silicon oxide layer on the substrate over an infrared (IR) reflecting layer(s) such as silver. The AR system surprisingly enables improved visible transmission and/or reflection to be combined with more neutral color.Type: GrantFiled: November 30, 2001Date of Patent: July 1, 2003Assignee: Guardian Industries Corp.Inventor: Grzegorz Stachowiak

Publication number: 20030096059Abstract: A composite raw material is subjected to masking, and then the composite raw material is pretreated. After that, a surface of the composite raw material is activated, and a metal catalyst is applied to a joining surface of the composite raw material and a surface of a masking tape. Subsequently, an electroless plating treatment is performed to form a plating layer on the joining surface of the composite raw material and the surface of the masking tape. It is preferable that the thickness of the plating layer is 5 to 100 &mgr;m. After that, the masking tape which has been stuck to the composite raw material is removed, and then a drying treatment is performed for the composite raw material having the plating layer formed only on the joining surface.Type: ApplicationFiled: November 13, 2002Publication date: May 22, 2003Applicant: NGK Insulators, Ltd.Inventors: Ken Suzuki, Shuhei Ishikawa
