Abstract: An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens sequentially arranged in numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system and each having a refractive power, wherein an entire field of view of the optical imaging system is 50° or greater, and TTL/f<1.0, where TTL is a distance from an object-side surface of the first lens to the imaging plane, and f is an overall focal length of the optical imaging system.

Abstract: A molding method for a cover window includes: locally heating a peripheral portion of a glass substrate around a central portion of the glass substrate to a temperature of about 610° C. to about 670° C., forming a cover window by pressing the glass substrate, and annealing and cooling the cover window. Accordingly, a cover window in which each of edges has an outwardly convex curved surface through a glass substrate may be formed. In addition, the surface roughness of a cover window formed through a glass substrate may be improved.

Abstract: Provided are a method and a device for converting a White-Red-Green-Blue (WRGB) color filter array into a Red-Green-Blue (RGB) color filter array in order to be easily applied to a commercial digital camera. The method includes (a) correcting a color of a White-Red-Green-Blue (WRGB) color filter array, (b) converting the WRGB color filter array into a Red-Green-Blue (RGB) color filter array, and (c) correcting a green of the RGB color filter array by using multichannel color difference value.

Abstract: A method of manufacturing a roll-type composite sheet including agitating a silicone gel using a mixer; agitating first powder and the silicone gel for 5 to 20 minutes to form a first mixture including at least the first powder and the silicone gel; agitating the first mixture and second powder for 5 to 20 minutes to form a second mixture; adding a solvent at least to the second mixture to form a reaction product being in a form of a paste; removing bubbles from the reaction product; coating the reaction product on a release medium at a temperature of 80 to 140° C.; and curing and drying the reaction product to form the composite sheet.

Abstract: Disclosed is a method for manufacturing a solid electrolytic capacitor using a functional polymer composition. The method comprises immersing the rolled aluminum electrolytic capacitor device in polyaniline solution with high electric conductivity to impregnate the device with polyaniline, drying the impregnated device in a drying oven which is maintained at constant temperature to fully remove the solvent, inserting the dried device to a capacitor aluminum can and then sealing with epoxy resin, to manufacture a solid electrolytic capacitor using a functional polymer. As such, the impregnation can be performed well at not only normal temperature and pressure, but also high temperature and reduced pressure. The solid electrolytic capacitor has the advantages of high capacity, low impedance and low ESR, and also, low manufacturing cost, simple processes and high reliability.
