System and method for packaging an LED is presented. A preferred embodiment includes a plurality of thermal vias located through the packaging substrate to effectively transfer heat away from the LED, and are preferably formed along with conductive vias that extend through the packaging substrate. The thermal vias are preferably in the shape of circles or rectangular, and may either be solid or else may encircle and enclose a portion of the packaging substrate.

A wind driven generator includes a rotor disposed in a cylindrical duct and supported by a frame for rotation in response to wind flowing through the duct. The rotor includes plural circumferentially spaced paralleled rotor blades supported for rotation about a generally horizontal axis. Each blade is supported for pivotal movement to change blade pitch, angle of attack or camber as the rotor rotates. A pitch or camber control motor or self-governing wind vane mechanism is operable to move a circular cam to vary blade pitch or camber to control rotor speed. The duct is mounted on a mast having a base supported on a foundation for pivotal movement to face the wind for maximizing air flow through the duct. Electric power generators are connected to opposite ends of the rotor at respective power output or drive shafts.

The present invention provides a process for producing pellet of EVOH comprising the steps of introducing an EVOH solution containing alcohol into an apparatus, contacting the solution with water in the apparatus to let out the alcohol with water and then letting out an EVOH hydrous composition from the above-mentioned apparatus (step 1); cutting the EVOH hydrous composition let out therefrom to obtain EVOH hydrous composition pellets (step 2); introducing the obtained EVOH hydrous composition pellets into a dryer to reduce a water content thereof (step 3); melt-kneading the pellets, whose water content is reduced, in an extruder (step 4); and cutting EVOH discharged from the extruder to obtain the pellet of EVOH (step 5). Thus, the EVOH hydrous composition obtained by removing alcohol without deteriorating the environment can be efficiently dried, and pellets having less thermal degradation in drying and a uniform shape can be obtained.

The present invention includes compositions and methods for making and using a vaccine that includes a DC-specific antibody or fragment thereof to which an engineered Gag antigen is attached to form an antibody-antigen complex, wherein the Gag antigen is less susceptible to proteolytic degradation by eliminating one or more proteolytic sites or a DC-specific antibody or fragment thereof to which an engineered Nef antigen is attached to form an antibody-antigen complex, wherein the Nef antigen comprises one or more codon usage optimization that increase antibody-antigen complex secretion, or both, wherein the vaccine is able to elicit an HIV-specific T cell immune response to Gag p17, Gag p24, Nef and / or Cyclin D1.

An illumination beam irradiation apparatus for use in pattern inspection systems is disclosed, which is less in deterioration of optical components and in attenuation of illumination light. The illumination apparatus includes a light source which yields a fundamental wave, a beam-shaper unit which performs beam-shaping of the fundamental wave so that this wave has a prespecified shape, and a pattern generator unit which operates, upon receipt of the beam-shaped fundamental wave, to convert this incoming wave into illumination light with a shorter wavelength to thereby generate illumination light of a prespecified shape. The illuminator also includes an image relay unit for guiding the illumination light that was generated by the pattern generator to fall onto a workpiece under inspection, such as a photomask or else.

An explosive detection system based on an ion mobility spectrometer detects the presence of trace molecules in air. Such instruments require an ion source to ionize the trace molecules. An ion source that does not require a radioactive source to operate can use the photoelectric effect to produce electrons. Such a photoelectric ion source will gradually be contaminated and lose its photoelectron emission properties when operated in the air. The photocathode of the ion source can be automatically regenerated by a heater in thermal communication with the photocathode. The heater may be activated when the photoelectron emission falls below a predetermined value ro may run or cycle continuously.

A low application temperature, high heat resistant hot melt adhesive comprising an ethylene n-butyl acrylate copolymer having a melt index (MI) of 750 grams / 10 minutes or higher and an ethylene vinyl acetate (EVA) polymer having a MI of 750 grams / 10 minutes or higher are particularly well suited for case and carton sealing operations.

The invention relates to a method for preparing aldehyde-free veneer boards by biological oil starch adhesives and belongs to the field of artificial board production. The method comprises the steps of biological oil starch adhesive preparation: vacuum filtration and reduced pressure distillation method are adopted for carrying out pretreatment on biological oil; wild cassava starch is added into water, starch emulsion and concentrated hydrochloric acid are prepared, after the temperature is raised, oxidants of persulfate are then added, and acidolysis oxidized starch emulsion is prepared through reaction; the biological oil is added into the emulsion, polyving akohol solution is added, then, alkali liquor and oxalic acid are repeatedly and alternately added; and then, borax is added until the viscosity reaches the requirements, and main agents of biological oil starch adhesives are obtained; and aldehyde-free veneer board preparation: single boards are dried and are subjected to adhesive coating at two sides by adopting the prepared adhesives, the single board blank assembly is carried out according to the odd layer principle and in a mode that the fiber directions of adjacent single boards are mutually vertical, the veneer boards are pressed and manufactured under the hot pressing curve, and the aldehyde-free veneer boards are obtained. The preparation process is simple, and the intensity of the prepared veneer boards reaches the requirements of II type veneer boards.
