Abstract: Disclosed is a transparent display device including an electrochromic element. The electrochromic element includes an electrochromic layer, a counter layer, and an electrolyte layer. An image is displayed through an oxidation-reduction reaction, and the display device is in a transparent mode when a voltage is not applied. The electrochromic layer and the counter layer may further include a core material for changing a color at a high speed.

Abstract: A reflective display device is disclosed, which includes first and second substrates facing each other, each of which includes a display area and a reflective area; a display element provided in the display area; and a reflective control element provided in the reflective area, controlling reflectance of externally incident light. The reflective display device may improve a contrast ratio by controlling reflectance of a reflective area when an image is displayed.

Abstract: Disclosed herein is a horizontal and vertical transportation system using permanent magnet excited transverse flux linear motors which is capable of linearly transporting an object in the horizontal direction and in the vertical direction using permanent magnet excited transverse flux linear motors, thereby obtaining a simple structure of the system and preventing any occurrence of dust generated by abrasion between the parts of the system. The system comprises a horizontal transportation unit and a vertical transportation unit. The horizontal transportation unit is adapted for transporting the object in the horizontal direction by means of a thrust from a permanent magnet excited transverse flux horizontal linear motor. The vertical transportation unit is installed on the horizontal transportation unit. The vertical transportation unit is adapted for transporting the object in the vertical direction by means of thrusts from permanent magnet excited transverse flux vertical linear motors.

Abstract: Disclosed is an integrated system of a non-contact power feed device and a permanent magnet-excited transverse flux linear motor, in which a conventional structure of the permanent magnet-excited transverse flux linear motor system is still used and a driving force and non-contact type power are supplied to a shifter of the permanent magnet-excited transverse flux linear motor, thereby eliminating defects of the electrical power supply system occurring due to the contact friction.
