  • 불순물을 이용한 비휘발성 홀로그램저장[1,2]은 기존의 열정착을 광정착으로 대치하는 방법으로서 여러 가지 희토류 혹은 전이금속이온을 첨가한 LiMbO$_3$ (LNO) 단결정 재료에서 시도되고 있다. 대표적인 재료로서 Mn,Fe:LNO 가 있으나 Mn,Ce:LNO, Cu,Co:LNO, Tb,Fe:LNO 등도 연구되고 있고 Stoichiometric LNO 경우엔 Pr:LNO, Er:LNO, Tb:LNO 등이 연구되고 있다. 그 외에 Mn:YAlO$_3$도 약하긴 하지만 비휘발성이 최근 보고되었다. (중략)

  • Resting membrane potential of atrial myocytes is less negative than K+ equilibrium potential, suggesting the presence of ion channels carrying inward currents. We investigated the background Na$\^$+/ current in rat atrial myocytes using both conventional whole cell voltage clamp technique and single channel recording.(omitted)

  • Recently, annual usage of energy is dramatically increasing by industrialization is going faster and more electricity is needed due to various electronic devices. This paper present relationships between the Vmax, $V_T$, load and time constant of solar cell charge and discharge curve. Charging and discharging recording where the external resistance will become larger Vmax, $V_T$ is decrease and the time increases and decreases there is a possibility of knowing.

  • Harmonics happened due to nonlinear systems such as UPS, SCR controlled motors, and fluorescent lighting in distribute power system is very important subject to optimal operate and control of power system. Harmonics sometimes takes place incorrect operation of protective relaying system under normal condition on power system. This paper presents the actual recording data of transformer located at substation of industrial installation for harmonic analysis in detail.

  • This study is focused on proposing a creative system that can display 3D hologram on the real-time basis. This method applies 3D display on volume hologram based on CGH. The process of implementing the system consists of two stages of fringe pattern recording for passive component that includes information on hologram, and irradiating object beam. Distinguished from an existing electronic holographic display system, this system is free from the process of a huge calculation that is necessary to compose CGH for a real-time 3D display.

  • In this study, the shape of suspension load beam for NFR(Near Field Recording) was proposed, which was designed using Topology optimization based on Homogenization method. Lens and Micro-mirror are attached to the end of the suspension load beam for collection and control the light, which increasing the system mass. Increment of the system mass cause to decrease the tracking stiffness mode frequency. (omitted)
