A coating apparatus having a housing (11) and a vacuum pump (31) for establishing a vacuum in the housing. First and second rotors (36, 37) are disposed within the housing for rotation about axes (38,39), which are offset from the horizontal by less than 45° whereby the upper portions of the rotors are in relatively close proximity to each other and the lower portions of the rotors are spaced apart from each other. A source (47) of coating materiat is disposed between the rotors generally in line with the axis of rotation of the rotors. The rotors have substrate (53) carrying surfaces having longitudinal dimensions extending generally parallel to the axis of rotation, which is such so that an imaginary vertical line extending downwardly from the top portion of the substrate carrying surface from the inner extremity of the same clears the outermost margin of the lower portion of the substrate carrying surfaces of the rotor whereby debris and the like falling by force of gravity from the top portion of the rotor will clear the lower portion of the rotor.

Contrast enhancement filter having first and second transparent glass substrates (16, 17) with first and second surfaces (18, 19; 21, 22) with the first surface (18,21) of each facing the medium in which the filter is disposed. A sheet-like circular polarizer (12) is provided formed of stretched plastic members (13) covered by layers (14) of cellulose acetate butyrate. The circular polarizer is disposed between the first and second glass substrates (16,17) and faces the second surfaces (19,21) of the glass-substrates. A dried plastisol primer layer (26, 27) is disposed on the surface of the layers of cellulose acetate butyrate facing the glass substrates. First and second layers (23, 24) of polyvinyl butyral adhesive secure the layers of cellulose acetate butyrate carried by the circular polarizer with the primer layers thereon to the second surfaces of the glass substrates. An anti-reflection coating (31) is disposed on the first surface of the first substrate. A method for manufacturing a contrast enhancement fil. ter which comprises the steps of providing a sheet-like circular polarizer (12) formed of stretched plastic members (13) and having outer layers (14) of cellulose acetate butyrate. A thin film (26, 27) of optical clear plastisol primer is applied on the outer surfaces of the cellulose acetate butyrate layers of the circular polarizer. The primer is then dried. A transparent substrate (16) is provided with first and second surfaces (18, 19). A layer (23)) of a polyvinyl butyral adhesive (23) is then applied to the second surface (19) of the first glass substrate. The circular polarizerwith its primer layerthereon is placed on the layer of polyvinyl butyral adhesive. Another layer (24) of polyvinyl butyral adhesive is then placed on the other side of the circular polarizer. A second glass substrate (17) having first and second surfaces (21,22) with the second surface (22) with the second surface (22) facing the polyvinyl butryral adhesive is placed in the sandwich. The various parts in the sandwich are then secured into a temporary unitary assembly. Air is evacuated from between the parts and the layers. Heat and pressure is applied to the assembly to cause the parts to be permanently bonded into a unitary assembly.

摘要:
A process for manufacturing electrochromic layers/devices at high rates and low deposition temperatures is described. The method utilizes the magnetron enhanced sputtering technique in which a substrate (36) is rotated past sputter cathodes (38, 40, 42, 44, 46) and past a reactive ion source (48) in order to deposit a layered electrochromic device. The process uses high system pressure and large reaction gas flow rates, but relatively low reactive gas partial pressures at the sputter cathodes (38, 40, 42, 44, 46) to reproducibly form electrochromic materials and devices which exhibit excellent optical and physical properties.
摘要:
The disclosure relates to high purity (95 - 99.5 percent) red, orange and yellow filters (10) which comprise a periodic stack of relatively low index of refraction dielectric material (L) such as SiO₂ or MgF₂ and absorbing relatively high index material such as silicon or Fe₂O₃. Together, the low and high index materials provide a high index ratio (typically 1.7 to 2.5). The filters (10) are fabricated according to designs such as (H/2 L H/2) n , typically using only 5 to 7 layers. Despite the very small layer count, these filters provide overall optical performance which is at least the equivalent of all-dielectric filters of 30 or more layers, with color purity that is unachievable by all-dielectric filters and simple low cost design. In addition, the filters have inherently low stress levels and absorb and reflect unwanted light such as blue light. As a conequence, the filters are ideally suited for coating on flexible substrates such as plastics and for coating on lamp envelopes to form red or yellow bulbs which are ideally suited, for example, for use as automobile tail light bulbs, side marker bulbs and turn signal bulbs.
