20130315764 | VALVE ACCELERATING TYPE DISPENSING PUMP - A dispensing pump, and more particularly, a valve accelerating type dispensing pump that may be used in a process of manufacturing an electronic product and may dispense an accurate amount of a liquid, such as a liquid synthetic resin, at high speed. The present invention provides a valve accelerating type dispensing pump that can descend a valve rod at high speed and thus can dispense a liquid with high viscosity at high speed. The valve accelerating type dispensing pump can dispense an accurate amount of a liquid at high speed. Also, the valve accelerating type dispensing pump can dispense a liquid having high viscosity at high speed due to a fast descending speed of a valve rod. | 11-28-2013 |

The present invention provides a valve impact type dispensing pump that can descend a valve rod at high speed and thus can dispense a liquid with high viscosity at high speed. The valve impact type dispensing pump can dispense an accurate amount of a liquid at high speed. Also, the valve impact type dispensing pump can dispense a liquid having high viscosity at high speed due to a fast descending speed of a valve rod. | 11-28-2013 |
20120190136 | METHOD AND APPARATUS FOR MANUFACTURING LED DEVICE - An apparatus and method of manufacturing a light emitting diode (LED) device, and more particularly, an apparatus and method of manufacturing an LED device by dispensing a fluorescent solution prepared by mixing a fluorescent material with a liquid synthetic resin, onto an LED chip. An apparatus and method of manufacturing an LED device, whereby an appropriate amount of fluorescent solution simultaneously in consideration of several factors, such as characteristics of an LED chip and viscosity of the fluorescent solution may be dispensed onto the LED chip, is provided. An apparatus and method of manufacturing an LED device, whereby an appropriate amount of fluorescent solution may be calculated actively in consideration of viscosity of the fluorescent solution, a change in characteristics of an LED chip, or the like, and the appropriate amount of fluorescent solution may be dispensed onto the LED chip, is provided. | 07-26-2012 |
20120065382 | METHOD AND DEVICE FOR EXTRACTING POLLEN PROTEINS - The present invention is one that, in a pollen protein extracting method, enables mass production, and while improving production efficiency, achieves a reduction in workload such as a reduction in man-hours, reductions in equipment cost and running cost, and an improvement of a work environment. Specifically, a pollen protein extracting method for extracting water-soluble protein from pollen is characterized by including: mixing the pollen and PBS; adding an aggregating agent including a natural inorganic component to a resultant mixed solution and performing stirring; and after formation of a pollen aggregate, performing filter filtration to perform solid-liquid separation. | 03-15-2012 |
20100330127 | SOLUBLE AGGREGATE, IMMUNE TOLERANCE INDUCER AND MANUFACTURING METHOD THEREOF - A soluble aggregate of allergen proteins, prepared by heating multiple allergen proteins and aggregating the allergen proteins and thus enclosing the antigen structures causing allergic reactions therein. | 12-30-2010 |
20100327468 | VOLUME-BASED DISPENSING CONTROL METHOD - A volume-based dispensing control method is capable of enabling a pump to dispense a resin with greatly increased accuracy. The method includes: a preliminary dispensing step in which a resin is dispensed on one or more workpieces with a pump; a volume measuring step in which the workpieces passed through the preliminary dispensing step is scanned by an optical scanner to measure a dispensed resin volume; a corrected-volume calculating step in which a corrected volume of the resin to be additionally dispensed is calculated by using a difference between the dispensed resin volume measured in the volume measuring step and a predetermined dispensing volume; and a corrective dispensing step in which the resin is dispensed on the workpieces in light of the corrected volume calculated in the corrected-volume calculating step. | 12-30-2010 |
20090279057 | Independent upper side and lower side drive type double-sided simultaneous exposure system - A maskless type exposure system using an exposure engine on which a digital micromirror device (DMD) is mounted includes an independent upper and lower side drive type double-sided simultaneous exposure system, in which a flexible object of exposure, including a flexible board, such as a chip-on-film (COF) or a lead frame, is fed in a rolled state, and is simultaneously exposed throughout an exposure pattern thereof on upper and lower sides thereof by independently driving a plurality of exposure engines in x, y and z axial directions in the case where the flexible exposure object has a large area or a restricted exposure region, thereby reducing costs based on minimized defective proportion and maximized productivity. | 11-12-2009 |
