Abstract:
본 발명에 따른 초전도 전력장치의 효율 향상방법은, 초전도 테이프를 권선하여 제작되는 초전도 전력장치의 효율 향상방법으로서, 상기 초전도 테이프 권선의 일부의 온도를 독자적으로 더욱 낮추어 상기 초전도 테이프 권선에 흐르는 전류를 크게 함으로써 온도가 낮춰지지 않은 다른 부분에서의 자기장 방향을 최대임계전류에 해당하는 자기장 방향과 일치하게 분포시키는 것을 특징으로 한다. 본 발명에 의하면, 온도를 부분적으로 조절함으로써 초전도 전력장치의 효율을 향상시킬 수 있게 된다. 초전도 테이프, 최대임계전류, 자기장, 온도, 효율, 초전도 자석
Abstract:
The present invention relates to an electron-donor compound having a novel structure, a method for manufacturing the same, and a photoelectric film and a photoelectric device comprising the same. The electron-donor compound according to the present invention is displayed in a novel structure of increasing a number of alkyl groups substituted of polythiophenes and increases solubility for a conjugated polymer, thereby showing effects of improving optical properties, electrochemical properties, and crystallographic properties of a photoelectric film and a photoelectric device comprising the electron-donor compound.
Abstract:
A three-dimensional chip stacked package module and its manufacturing method are provided to simplify a manufacturing process and implement an inexpensive package by adhering chips on a flexible board using an adhesive. A three-dimensional chip stacked package module includes plural chips having a non-solder bump, and a flexible board having an upper metal pad to be connected to the non-solder bump and a lower metal pad to be connected to an external circuit board. The non-solder bump is connected to the metal pad via a first adhesive layer, and a bottom surface of the chip is connected to the flexible board by a second adhesive layer.
Abstract:
A method for bonding electrical devices to each other is provided to improve the yield and productivity and to enhance reliability of a bonding process by using ultrasonic waves capable of hardening an adhesive. First and second connection electrodes of electrical devices are arranged with each other. An adhesive is interposed between the first and second connection electrodes of the electrical devices. The adhesive is hardened by using an exothermic reaction of the adhesive itself. At this time, the exothermic reaction of the adhesive is caused by ultrasonic waves. A conductive adhesive or a non-conducting adhesive is used as the adhesive.
