A device and method for measuring water and oxygen permeation rates of a protective layer in an organic electronic device are provided. The device includes: a glass substrate; a pair of electrode layers facing each other and deposited on the glass substrate; a calcium layer deposited on the glass substrate; a water and oxygen permeable substrate deposited on the calcium layer; a target protective layer of an organic electronic device, which is deposited on the water and oxygen permeable substrate; and a sealing material applied along an edge of the target protective layer, wherein one ends of the pair of electrode layers are buried in the calcium layer and the other ends are electrically connected to an external resistance measuring device.Accordingly, high reliability can be achieved, applicability to various processes for the protective layer in the organic electronic device can be enhanced without affecting reflectance or transmittance of the protective layer, and a defect averaging operation does not need to be performed on a calcium layer within the device unlike the conventional art, by using a principle that electrical characteristics of the device are changed when the water or oxygen permeates the protective layer.

An anode composition for a lithium secondary battery is provided. The anode composition comprises an anode active material, a conductive material, and an acrylonitrile-acrylic acid copolymer with a high molecular weight as a binder. The acrylonitrile-acrylic acid copolymer has a molar ratio of acrylonitrile to acrylic acid of 1:0.01-2. Further provided are a method for preparing the anode composition and a lithium secondary battery using the anode composition. The binder has improved resistance to an electrolyte solution due to its enhanced adhesive strength. In addition, the use of the anode composition prevents the active material layer from being peeled off or separated from a current collector during charge and discharge to achieve improved capacity and cycle life characteristics of the battery.

An image recording/reproducing device to change a start point of a fade effect to represent a boundary between image files in a device to record/reproduce an image file so as to easily distinguish an image file displayed on a screen. A method to process a fade effect in the image recording/reproducing device includes filming a moving image, encoding the filmed moving image, and applying the fade effect when the moving image is encoded and recording a moving image file. In the moving image file, a second section to which the fade effect is applied is located after a first section to which the fade effect is not applied. Accordingly, distinguishing the moving image file with the fade effect in a reproduction mode, a preview mode of a window explorer and an image editing application without changing an algorithm is possible.

A heat exchanger having a structure in which micro-channel tubes are respectively fitted into both sides of corresponding flat fins for heat exchange, thereby achieving enhancements in drainage and heat transfer performance. The heat exchanger includes a first header extending vertically and connected with an inflow tube and an outflow tube, a second header spaced apart from the first header by a desired distance and arranged parallel to the first header, and a plurality of flat micro-channel tubes arranged horizontally while being vertically spaced apart from one another by a desired clearance and arranged in a front row and a rear row between the first header and the second header. Micro-channels are formed in each of the micro-channel tubes.
摘要:
An image reading apparatus capable of changing a main reading unit at an appropriate time point such that a plurality of reading units can be equally used, and a method of controlling the same. The image reading apparatus includes an automatic document feeder, a first reading unit to read a first side of a document fed by the automatic document feeder and to function as a main reading unit, a second reading unit to read a second side of the document fed by the automatic document feeder; and a control unit to change the main reading unit from the first reading unit to the second reading unit if the number of times La of usage of the first reading unit reaches a reference value. The control unit compares the number of times La of usage of the first reading unit with a predicted lifetime Lt of the first reading unit and changes the main reading unit to the second reading unit if it is determined that the number of times La of usage of the first reading unit reaches a predetermined percentage of the predicted lifetime of the first reading unit. The control unit determines whether the main reading unit is changed or not, based on frequencies of use of the first reading unit and the second reading unit.
