An (Al, Ga, In)N and ZnO direct wafer bonded light emitting diode (LED), wherein light passes through electrically conductive ZnO. Flat and clean surfaces are prepared for both the (Al, Ga, In)N and ZnO wafers. A wafer bonding process is then performed between the (Al, Ga, In)N and ZnO wafers, wherein the (Al, Ga, In)N and ZnO wafers are joined together and then wafer bonded in a nitrogen ambient under uniaxial pressure at a set temperature for a set duration. After the wafer bonding process, ZnO is shaped for increasing light extraction from inside of LED.
摘要:
A die for press-molding glass optical elements which can press-mold glass optical elements having high melting points and various shapes repeatedly, which includes a base material having high strength on which a cutting layer having heat resistance and free cutting machinability is formed. After cutting the cutting layer into the desired shape with high accuracy, the die is coated with a surface protective film.

A method for making optical preforms of optical elements without residual stress or distortion is provided. In this method, an optical material is supplied between upper and lower molds. The upper mold has a plurality of recesses arranged in a predetermined pitch, and each recess corresponds to a first surface shape of the optical element. The lower mold has a plurality of recesses facing the recesses of the upper mold and each recess of the lower mold corresponds to a second surface shape of the optical element. The supplied optical material is pressed between the upper and lower molds to be a set of optical preforms. The set of optical preforms is processed by die punching or tool cutting to separate each optical preform from the set of optical preforms. Each optical preform is used for producing an optical element by further pressing. Alternatively, optical element can be formed directly by the press molding process.

The present invention provides a continuous automatic steel making method and a facility which make it possible to make steel continuously and automatically by systematizing all steps of the steel making process. Steel is tapped from an electric furnace while steel making materials are continuously charged into the electric furnace. The tapped molten steel is delivered to a ladle supported by a conveying car. The conveying car is moved to a position associated with a continuous casting machine. The ladle containing the molten steel is moved from the conveying car to a position above a tundish of the continuous casting machine and the conveying car is then returned to the electric furnace. The molten steel is poured from the ladle into the tundish. All of the steps are continuously controlled and coordinated by a master controller.
摘要:
A method for improving the internal surface of a gas-barrier, when required heat-shrinkable, multi-layer plastics film laminate in the form of a seamless tube having the innermost layer of olefin resin, the method including applying corona discharge employing at least two pairs of electrodes to the innermost layer from the outside of the tube having a gas sealed therein and pressed to a flat state avoiding the contact of opposed surface areas of innermost olefin resin layer with each other, the two pairs of electrodes being arranged such that one electrode of each pair is in contact with the outermost layer of the tube and the other of the same pair out of contact therewith while one electrode of one pair is kept in contact with the outermost layer of the tube with which one electrode of another pair is kept out of contact on the same side of the tube, so that the wetting tension of the innermost layer surface is increased to at least 35 dyne/cm by the corona discharge treatment.
摘要:
Hypo-allergenic jasmine oil is presented. This hypo-allergenic jasmine oil can be obtained by removing coniferyl benzoate and coniferyl acetate from natural flower essential jasmine oil by means of distillation, molecular distillation, preparative gas chromatography, preparative column chromatography, alkaline treatment or any combination thereof.

摘要:
An image from a camera is to be recorded and reversion is to be made to an image of an optional scene to reproduce an image of such scene. To this end, a CPU 20 converts image signals at a rate of 90 frames per second from a camera device 10 into parallel signals to output image signals of the usual rate of 30 frames per second. A video server 30 records the image signals from the CCU 20 on a RAID 32. If a pre-set scene is to be reproduced, the image signals are read out from the RAID 32 in the order of the original image signals to output the read-out image signals to outside.
