The present invention relates to warm white light engines including combinations of blue, cyan, and red, red-orange, or amber emitters and one or more phosphors that produce a white light pleasing to the human eye through the use of improved color uniformity and improved collimation of light. Specifically, a micro-lenslet array having an optimized surface is used to disperse light from the light emitter; an innercollimation lens having an optimized cross-sectional shape and micro-ridges is used to disperse light; a TIR reflector having an optimized cross-sectional shape and micro-ridges is used to disperse and redistribute phase as well as provide collimation; and a final micro-lenslet layer includes optimized lenslet design placement and randomization factor to homogenize light to produce a uniform warm white light.

A method for heating a wafer to a predetermined temperature, the wafer being held by a holding unit and being accommodated in a processing container equipped with a heater. The wafer is heated to a processing temperature while positioning the wafer at an adjacent position that results form making the wafer approach the heating surface of the heater. After heating the wafer to the predetermined temperature, the wafer is separated from the flat bottom surface of the container body to a processing position. In this state, a processing chamber of the processing container is supplied with a processing fluid, while the holding unit and the heater are relatively moved close to and apart from each other intermittently or continuously. Accordingly, it is possible to quickly heat the substrate to a processing temperature while supplying the substrate with the processing fluid uniformly. This improves throughout and the homogenization in processing.

Certain example embodiments relate to improved lighting systems and/or methods of making the same. In certain example embodiments, a lighting system includes a glass substrate with one or more apertures. An LED or other light source is disposed at one end of the aperture such that light from the LED directed through the aperture of the glass substrate exits the opposite end of the aperture. Inner surfaces of the aperture have a mirroring material such as silver to reflect the emitted light from the LED. In certain example embodiments, a remote phosphor article or layer is disposed opposite the LED at the other end of the aperture. In certain example embodiment, a lens is disposed in the aperture, between the remote phosphor article and the LED.

An endoprobe for ophthalmic microsurgery for intraocular treatment of the eye and that affords a surgeon good visibility regardless of the distance from the treatment site in the eye. The endoprobe includes a stainless steel cannula enclosing one or more optical fibers and a laser fiber. A distal end of the optical fibers can be closed by a transparent lens-shaped structure such that an illuminating light transmitted through the optical fibers is radiated and transmitted laser light can exit from the laser fiber, or such that the laser fiber is embedded in a transparent shaped element. The laser fiber may have a covering for transporting light. The laser light may be injected directly into the laser fiber and the illuminating light is injected via at least one optical element into the covering of the laser fiber or into the transparent shaped element.

The invention discloses environment-friendly cement. The raw materials include various industrial waste residues, limestone, cement clinker, gypsum, a grinding aid and an excitation substance. The environment-friendly cement is characterized in that the weight parts of the raw materials are as follows: 50-60 parts of admixture, 32-40 parts of cement clinker, 4-8 parts of gypsum, 0.03-0.05 part of grinding aid and 3-5 parts of excitation substance. Since the production process of the environment-friendly cement adopts a low-temperature mechanical-chemical co-excitation technology, the mixing amount of the admixture is large, multiple industrial waste residues can be used as raw materials, the raw materials are widely available, the cost is low, a great quantity of industrial waste residues can be consumed, the waste is turned into wealth, and the performance of the obtained product is remarkably improved from the quality index.

The invention discloses a preparation method of specially-shaped cigarettes with naturally endowed aroma. The preparation method comprises the following steps: respectively grinding a tobacco raw material and natural plant perfumes into powder, and uniformly mixing the powder, thus obtaining mixed powder; uniformly stirring a combustion promoter, an adhesive and a humectant, thus obtaining a mixedsolution; carrying out mixed granulation on the mixed powder and the mixed solution, and carrying out drying, thus obtaining tobacco particles; preparing the tobacco particles into tobacco particle round rods by adopting a tobacco particle round rod forming device; wrapping the tobacco particle round rods by adopting cigarette paper, carrying out cutting forming, and carrying out compounding withfilter sticks, thus obtaining the specially-shaped cigarettes with high homogenization, good stability and naturally endowed aroma. The cigarettes are smooth in smoking, the aroma is fresh and elegant, and good sensual experience can be endowed to a smoker.

A method for diagnosing an exhaust-gas catalytic converter (28) arranged in an exhaust-gas system (20) of an internal combustion engine (12) for the catalytic conversion of at least one exhaust-gas component from the internal combustion engine (12), which has an exhaust-gas recirculation means with which a partial stream of the exhaust gas can be drawn off downstream of the catalytic converter (14) and fed into the combustion air of the internal combustion engine (12), involves determining the current raw emission (NO_x—raw) of the internal combustion engine (12) in of the exhaust-gas component; measuring the current concentration of the exhaust-gas component (NO_x—meas) in the exhaust gas upstream of the catalytic converter (28); and determining a diagnostic value for the catalytic converter (28) in terms of the conversion of the exhaust-gas component as a function of the modelled raw emission (NO_x—raw) from the internal combustion engine (12) and the measured concentration of the exhaust-gas component (NO_x—meas). The invention further relates to a diagnostic device configured to perform the method and a motor vehicle having such a device.

The invention discloses a preparation method of naturally aromatized cigarettes. The preparation method comprises the following steps: grinding a tobacco raw material and natural plant perfumes into powder respectively, and uniformly mixing the powder with a pore-foaming agent, hot melt adhesive powder and a combustion improver, thus obtaining mixed powder; uniformly stirring an adhesive and a humectant, thus obtaining a mixed solution; carrying out mixed granulation on the mixed powder and the mixed solution, and preparing the obtained reconstituted tobacco/perfume composite particles into tobacco particle round rods by adopting a tobacco particle round rod forming device; and wrapping the tobacco particle round rods by adopting cigarette paper, carrying out cutting forming, and carryingout compounding with filter sticks, thus obtaining the cigarettes which are high in hardness, are mellow and full, and have regular and attractive cutting faces. The cigarettes are high in homogenization degree and good in stability, the problem that the homogenization is difficult to satisfy existing in the existing cigarettes is fundamentally solved, and the phenomena of tobacco shred falling atthe cut opening and empty head existing in the conventional cigarettes are avoided. The cigarettes are smooth in smoking and strong in satisfaction, the aroma is fresh and elegant, and good sensual experience can be endowed to a smoker.
