Magnetic material and bonded magnet
This technology concerns a newly developed RFeN type permanent magnetic powder, a bonded magnet and these manufacturing processes. This material has high intrinsic magnetic properties being as good as that of noted NdFeB type magnetic material. This technology provides a magnetic material having high magnetic properties such as high saturation magnetization, residual magnetization intrinsic coercive force and loop rectangularity as well as high magnetic anisotropy. Also, this material is good for the manufacturing of injection molding and compression molding magnets which will enable a desired shape, high productivity and excellent properties. This technology is characterized by a unique method of nitriding RFe alloy uniformly.

Novel agarase enzyme system suitable for production of mono- and oligosaccharides
A novel agarase enzyme system has been discovered which has been found to significantly improve the synthesis of short chain length oligosaccharides or monosaccharides from agarose (the principle polysaccharide component of agar) or longer chain length oligosaccharides derived from agarose. Monosaccharides and short chain length oligosaccharides are known to inhibit the degradation of starch in a variety of products. Laboratory-scale production currently.

Unique light-piping security feature for ID cards
This technology adds to the security of identity cards or authentication badges by adding a feature that cannot be copied or imitated. Verification is possible by no other means than daylight or visible light and the naked eye. The proposed security feature allows the authentication of security documents such as an identity card requiring only daylight and the naked eye. Between an outer and an inner resin layer a special fluorescent dye is incorporated that responds to visible light and pipes the fluorescent light to the edge of the card. The edge of the security card then emits yellow light visible to the naked eye. This security feature cannot be copied or counterfeited. Working prototypes have been produced.

Advanced corrosion protection using zinc-alloy coating
This technology is an advanced coating based on an amorphous zinc-rich alloy which offers superior corrosion protection to other zinc alloy coatings currently in use in industry. Zinc-rich coatings are preferred in industry because they offer advantages in terms of their enhanced sacrificial protection, also their cost of fabrication. Unlike crystalline zinc-rich alloys, this coating is impervious to de-alloying and ultimate loss of sacrificiality in corrosive environments. The coating offers comparable barrier protection to low-zinc alloy coatings, but without their inherent limits on the sacrificiality of the coating. A simple and cost-effective process for the rapid application of this coating to a variety of substrates has been developed. This process uses an unbalanced magnetron sputtering vapor deposition system.

Time-release laminar pharmaceutical formulation
A time-release laminar pharmaceutical composition, comprised of rolled or folded layers of a polymer film, that contain a pharmaceutically active substance and which is accessible to the digestive fluids. The rolled or folder layers adhere to one another in such a way that the laminar form maintains its form after ingestion and provides a sustained drug release. New types of solid oral dosage forms are described, which are made from drug containing films by rolling or folding. The laminated structure controlls delayed drug release very precisely by diffusion through constant areas and shapes. Manufacturing is more easy and economical because expensive batch processes like mixing, compression and coating are avoided. Laboratory trials have been conducted.

New stabilizer for polymers
In an outdoor environment polyolefins discolor and loose their mechanical properties. To make polymers useful for outdoor applications they contain UV-stabilizers (also named photo stabilizer or weathering improver). New chemicals were discovered that show a synergism with the best UV-stabilizers in use. These synergetic combinations can lead to much longer lifetimes and make polymers applicable in new areas.

Oxidation of alcohols Using optimized nitroxyl radicals as Catalysts
Commercially and ecologically viable preparation of 2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPO). This compound is used in the chemical industry e.g. as catalyst, stabilizer or polymerization regulator. Highly efficient and selective preparation of aldehydes from primary alcohols. Highly efficient and selective preparation of ketones from secondary alcohols. Heterogeneous TEMPO-type catalyst allow simple removal of catalyst during work-up. The isolated catalyst can be recycled. Advanced development.

Hologram printer
A hologram printer may be usable for optical memories, three-dimensional maps or articles, three-dimensional copy machines or displays, and so on. This printer can generate computer-assisted holograms from two- or three-dimensional image data. The apparatus includes a diffraction image generator which receives an input image signal representing an object and computes a corresponding diffraction pattern with a first sampling density. An interpolation processor is connected to the diffraction image generator via an intermediate page memory. The interpolation processor subjects the diffraction pattern to the interpolation process to create an interpolated diffraction pattern with an increased second sampling density. An interference pattern generator is connected to the interpolation processor to compute an interference caused pattern between the interpolated diffraction pattern and a reference wave by converting amplitude and phase distributions of the input image signal into the intensity distribution.

Optical crossbar switch
This technology is a semiconductor optical crossbar switch consisting of a network of optical waveguides that can direct optical signals from any of N input ports to any number of M output ports. Its key benefits are low operational voltage and power, small chip size, high throughput, and short reconfiguration time. It also provides optical amplification to compensate for splitting and coupling losses. By utilizing optical signaling throughout the device, the transmission bandwidth is large and the switching network is not susceptible to EMI.

Fast, non-invasive measurement of oxygen saturation
Different favorable possibilities of chemical recycling are covered by the family of patents offered. The processes include the conversion of polycarbonate waste to useful new products as well as simple and economical ways to recover monomers in high yields. The technologies include: A process for the continuous splitting of polycarbonates into dihydroxy compounds and carbonic acid esters by catalytic transesterification with monohydroxy compounds. A process for cleaving polycarbonates into bisphenols and diaryl carbonates by transesterification with phenols in the presence of catalysts. A process for the continuous cleavage of aromatic polycarbonates to give dihydroxy compounds and dimethyl carbonate by catalytic transesterification with methanol in a distillation column, using a solution of polycarbonate in mono-hydroxy compounds other than methanol, and others.
