Abstract: This invention introduces an improved method for bonding two surfaces using silk-screen printing technology. The method according to the invention reduces possible occlusion of the screen, thus improving the print quality of the deposited cement film. This is accomplished by adding particles to the print medium. In addition, by selecting the size of the particles it is possible for these, serving as spacers during the bonding process, to define the thickness of the cement layer. An additional procedural step describes the controlled mutual approach of the bonding surfaces.

Abstract: An optical filter for manipulating the spectrum of a light source is comprised of a transparent substrate and a first layer system applied to only one side, preferably an interference layer system. The substrate and the first layer system form a combined UV and IR filter (UV-IR filter) such that radiation portions both below a wavelength of 420 nm, particularly in the UV range, and above a wavelength of 690 nm, particularly in the IR range, are not fully transmitted via the first layer system.

Abstract: In a method for manufacturing an optical storage medium a first 1 and a second circular substrate 2 are being provided and being joined by means of a W curable resin forming an intermediate bonding layer. Then said two bonded substrates are being illuminated with UV light with the exception of the very outer edge of the bonded disc. Afterwards said two bonded disks are being spun and thereby a removal of unwanted resin (adhesive) from the outer edge takes place.

Abstract: A disk for optical storage media is being embossed with information during the injection molding process on both sides. Using 2 such disks, a reflective coating is being applied on the front side of the first disk and a resin layer is being applied on said reflective coating. Then the back side of said second disk is being pressed into the resin layer to transfer the embossed information to the first disk. After separating said second disk from the first one the second disk is being used as first substrate in a subsequent process, thereby avoiding any waste stamper disk.

Abstract: A color wheel for use in projector systems comprises a disc shaped hub, rotatable around a central axis and color filter segments arranged radially to said central axis and affixed to said hub. This color ring is arranged concentrically with respect to said axis and said segments' contour comprising an outer arc, an inner arc and two radial parts. Each of the radial parts comprises a recess arranged such that during assembly of said segments pairs of neighboring recesses form a hole which again engages in a corresponding peg on the hub in a form fitting manner.

Abstract: A composite solar collection module includes a thin film solar collection cell that is encapsulated between a transparent substrate, such as glass, on one side, and an electrically insulating film on the other. A metallic layer is disposed over the electrically insulating film to provide protection against diffusion of atmospheric species that may harm the thin film solar collection cell. The insulating and metallic layers are dimensioned so that a larger collection cell can be used to collect solar energy over a larger proportion of the available substrate surface area, without causing arcing between the cell edge and the metallic layer edge.

Abstract: A Method for manufacturing an optical disc substrate comprises a first substrate with at least one structured surface, on which an anti-adhesive layer, preferably carbon, is deposited and first layer on top of said anti-adhesive layer. On a second substrate with a structured surface also a layer is deposited. Both substrates are bonded together with the layers facing each other. The separation now easily can take place afterwards alongside the adhesive layer. This way the first layer from the first substrate is being transferred to the second substrate.
