  • Patent number: 7208235
    Abstract: The present invention provides a method for forming a transparent thin film by a chemical vapor deposition method using a gaseous raw material. In the method, a film growth rate is at least 8 nm/s, and the transparent thin film contains at least one selected from carbon (C) and oxygen (O), nitrogen (N), hydrogen (H), and silicon (Si). According to this method, a transparent thin film that does not peel off a substrate easily due to the eased tension in the thin film and has high transmittance in the visible light region can be deposited on a glass ribbon in a float bath.

  • Patent number: 7198851
    Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.

  • Patent number: 7189458
    Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a fairly low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer (e.g., NiCrOx) may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.

  • Patent number: 7172821
    Abstract: A coating material has a first layer deposited on a base material and a second layer deposited on the first layer. The first layer is made of a Ni-base alloy or a Co-base alloy containing carbon as an unavoidable impurity. The second layer is made of a hard material containing carbide and a metal component. The first layer serves as a barrier for preventing carbon from being diffused from the second layer into the base material to prevent the base material from being carburized.

  • Patent number: 7153567
    Abstract: A composite structure forming method comprises the steps of first pre-treating brittle material fine particles to impart an internal strain to the brittle material fine particles, secondly causing the brittle material fine particles in which the internal strain has been created to collide with a substrate surface at high speed or applying a mechanical impact force to the brittle material fine particles containing the internal strain therein provided on the substrate surface, to deform or fracture the brittle material fine particles, re-joining the fine particles through active new surfaces generated by the deformation or fracture, forming an anchor section made of polycrystalline brittle material of which part bites into the substrate surface at a boundary section between the new surfaces and the substrate, and further forming a structure made of polycrystalline brittle material on the anchor section.

  • Patent number: 7153579
    Abstract: A low-E coated article is provided, in certain example embodiments, with a layer including tin oxide provided between a layer including titanium oxide and a layer including silicon nitride. It has been found that the provision of such a tin oxide inclusive layer between silicon nitride and titanium oxide can significantly improve durability of the resulting coated article, especially after heat treatment (HT). In certain example embodiments, the coated article may be formed so as to have a fairly high visible transmission (TY or Tvis) to sheet resistance (Rs) ratio (i.e., a ratio Tvis/Rs). Coated articles herein may be used in the context of windows or the like (e.g., laminated vehicle windshields).

  • Patent number: 7150916
    Abstract: A coated article is provided which may be heat treated (e.g., thermally tempered) and/or heat bent in certain example instances. In certain example embodiments, an interlayer of or including a metal oxide such as tin oxide is provided under an infrared (IR) reflecting layer so as to be located between respective layers of or including silicon nitride and zinc oxide. It has been found that the use of such a tin oxide inclusive interlayer results in significantly improved bendability of the coated article in applications such as vehicle windshields with deep bends. In certain example instances, an overcoat of a material such as zirconium oxide may also be provided.
