  • Patent number: 8288060
    Abstract: Disclosed are a metal-supported solid oxide fuel cell and a method for manufacturing the metal-supported solid oxide fuel cell. The method includes: fixedly joining a metal support to one surface of a unit cell including a fuel electrode, an air electrode and an electrolyte layer interposed between the fuel and air electrodes to fabricate a metal-supported unit cell (S210); fixing a first separator to the surface of the metal support opposite to the surface thereof to which the unit cell is joined (S220); and assembling the first separator to which the metal-supported unit cell is fixed, an insulating member, a first current collecting member and a second separator (S230). In the metal-supported solid oxide fuel cell, the metal support having a hollow portion in place of a mesh type current collector can be securely sealed to the first separator by direct welding to allow the fuel gas and air to be supplied to the unit cell through respective defined flow passages without being mixed or leakage.

  • Patent number: 8136052
    Abstract: A touch screen device and an operating method thereof are provided. The touch screen device is operated by touching a touch screen and moving a touch while the touch is maintained on the screen. A detector detects a touch point and a moving trajectory, and a controller selects a user command based on the detected touch point and moving trajectory. Then, when the user releases the touch, the controller executes the user command. User commands are classified and stored in a storage device and then executed by the controller based on operation modes associated with the device. A variety of user commands may be executed even though not all the menus are not displayed on the screen at once. Further, a user may cancel an erroneously entered user command quickly and easily.

  • Patent number: 7916125
    Abstract: A touch screen device and method of displaying images using display windows and selecting execution menus displayed on the display windows in a touch screen device are provided. The touch screen device includes a screen, a display configured to display images thereon and a detector configured to detect a touch on the screen, and a controller configured to control operation of the touch screen device in accordance with the screen touch detected by the detector. The controller causes two or more display windows to be displayed in an overlapped manner. Further, if the touch is detected on an underlying display window covered by an overlying display window, the controller causes a display form to be changed in response to the touch. That is, if a touch is detected on the display window covered by the overlying display window, the touched display window is displayed as an overlying display window.

  • Patent number: 7737958
    Abstract: A touch screen device and method for displaying and selecting menus thereof are provided. The touch screen device includes a screen with a display for displaying menu images thereon and a detector for detecting a touch on a screen, and a controller which displays one or more menu bars on the screen. Each of the menu bars may have an expanded portion at one end thereof, and the menu bars may be displayed such that the expanded portions are arranged in a zigzag pattern to facilitate menu selection and reduce input errors. When two or more menu bars are erroneously touched, the controller may enlarge and display the touched menus so that a new touch input for the correct menu can be easily made. Thus, menus displayed on the touch screen may be arranged for easy selection, and input errors may be easily corrected.
