20090016205 | Optical Recording Medium and Method for Reproducing Information From Optical Recording Medium - An optical recording medium includes a substrate, a first dielectric layer, a recording layer, a second dielectric layer, a super-resolution layer, and a third dielectric layer, which are provided in that order. The super-resolution layer is formed of a material configured such that voids are generated when the material is irradiated with DC light at a predetermined irradiation power for 1 to 300 seconds. Therefore, super-resolution reproduction can be made such that the irradiation power of a readout laser beam does not depend on the size of a recording mark. | 01-15-2009 |
20100034566 | LIGHT ABSORBENT MEMBER, HEATING DEVICE, FIXING DEVICE AND IMAGE FORMING APPARATUS EMPLOYING THE SAME - Disclosed are a novel light absorptive member, a heating device employing such light absorptive member, a fixing device employing such heating device and an image forming apparatus that uses the fixing device. The light absorptive member includes nano-rods dispersed therein, and can increase absorption efficiency of a heating device, such as, for example, a fixing device that uses a light source as a radiant heat source, due to the surface plasmon resonance phenomenon that occurs when the wavelength(s) of the light corresponds the peak wavelength(s) of the absorptive rate for the light based on the aspect ratio(s) of the nano-rods. | 02-11-2010 |
20100111580 | LIGHT ABSORPTION DEVICE, FIXING UNIT COMPRISING THE LIGHT ABSORPTION DEVICE AND IMAGE FORMING APPARATUS COMPRISING THE FIXING UNIT - Disclosed are a light absorption device, a fixing unit including the same and an image forming apparatus including such fixing unit. The light absorption device includes a plurality of dielectric layers containing nano-rods. Surface plasmon resonance generated in response to certain wavelengths corresponding to the dielectric constants of the dielectric layers can result in an improvement in the light absorption efficiency. Further improvements can be realized by adjusting the dielectric constants of the dielectric layers. | 05-06-2010 |
20100129125 | LIGHT-ABSORPTIVE DEVICE, FIXING UNIT USING THE LIGHT-ABSORPTIVE DEVICE, AND IMAGE FORMING APPARATUS - A light-absorptive device for absorbing light includes a light source configured to emit light and a light-absorptive element configured to absorb the light emitted from the source. The light-absorptive element includes a light-absorptive layer in which a nano-component comprised of one or more nano particles coated with a shape keeping agent is dispersed. The aspect ratio(s) and/or the dielectric constant of the light-absorptive layer may be selectively varied to realize a peak wavelength of absorption spectrum that corresponds to the wavelength(s) of the light emitted by the light source. The light-absorptive device may be incorporated as a heating unit, such as a fixing unit of an image forming apparatus to fix toner images on to a recording medium. | 05-27-2010 |
20100157306 | APPARATUS AND METHOD FOR DETECTING SURFACE PLASMON RESONANCE - Disclosed are an apparatus and a method for detecting a surface plasmon resonance. The apparatus may radiate a polarized beam of light to a device, such as a surface plasmon resonance generator, and may measure variations in a temperature of the device to detect whether a surface plasmon resonance has occurred. The detection of a surface plasmon resonance may be associated with the presence of a particular material such as volatile organic compounds (VOCs) or materials disrupting ozone, for example. | 06-24-2010 |
20100188959 | INFORMATION STORAGE MEDIUM AND APPARATUS FOR RECORDING/REPRODUCING THE SAME - An information storage medium and an apparatus for recording/reproducing the same are provided. The information storage medium is provided in which repetitive recording is performed by using nanorods formed of a material capable of repeatedly changing light absorption. | 07-29-2010 |
20100202272 | METHOD OF FABRICATING NANOROD INFORMATION STORAGE MEDIUM - A method of fabricating an information storage medium, the method including forming a plurality of nanorod recording layers on a substrate by sputtering using a mask having a plurality of nanorod patterns. | 08-12-2010 |
20120063253 | OPTICAL MEMORY DEVICE AND METHOD OF RECORDING/REPRODUCING INFORMATION BY USING THE SAME - An optical memory device and a method of recording/reproducing information by using the optical memory device. The optical memory device includes a substrate; a first barrier layer formed on the substrate; a quantum well layer; a second barrier layer; a quantum dot layer; and a third barrier layer. The quantum well layer has an energy band gap which is wider than that of the quantum dot layer, and the second barrier layer has an energy band gap which is wider than that of the quantum well layer, so that electrons in excitons which are generated in the quantum dot layer by light of a certain wavelength are captured by the quantum well layer to record information, and then, recorded information may be erased or reproduced by irradiating light of a certain wavelength to the optical memory device. | 03-15-2012 |
20130149537 | HARD COATING COMPOSITION - A hard coating composition capable of being applied to the modification of a surface of plastic material that is being widely used in household appliances, the hard coating composition including an inorganic dispersion solution that is composed of at least one hydrolytically decomposable silane compound and an inorganic oxide particle, and an organic resin solution that is composed of a photo-curable acrylic-based compound and various additives capable of providing a functionality, such as a surface improving agent and an anti-static agent, the hard coating composition providing pH of between 4 and 6. | 06-13-2013 |
