A light emitting device includes such a patterned film as a light emitting layer.

Abstract: A control system includes a flow control valve for control of a coolant flow path and a controller configured for control of an opening amount of the flow control valve. The flow control valve includes ports respectively communicating with a fuel cell stack, a radiator, a coolant pump, and an ion filter. The controller is configured to control the flow control valve to open a first port connected to the ion filter within a predetermined section in a temperature control section of a fuel cell thermal management system. The temperature control section is a section between a point where the second port connected to the radiator is completely closed and the third port connected to the fuel cell stack is completely opened and a point where the second port connected to the radiator is completely opened and the third port connected to the fuel cell stack is completely closed.

Abstract: A device to prevent fire of a fusing belt having a heater positioned inside includes at least one temperature control member adjacent to one side of the fusing belt and, when the at least one temperature control member detects abnormal heat from the fusing belt based on a temperature of the fusing belt, the at least one temperature control member to cut off a supply of electricity to the heater to prevent the fire. The device also includes a heat absorption member adjacent to the other side of the fusing belt and to absorb latent heat from the fusing belt to lower the temperature of the fusing belt to prevent the fire.

Abstract: A menu displaying method in a mobile terminal. When a user opens a menu function, a list of menu items is displayed on a display. Upon user selection of a menu item from the list, the selected menu item is perceivably displayed. It is determined whether a sub-menu of the menu item has been set as status information of the menu item. If the sub-menu has been set as the status information, a bubble window having the status information is displayed near the menu item.

Abstract: A method and device for inputting recipient information in a handheld terminal is provided. This method and device facilitates a user's ability to dynamically create and delete an input field for inputting the recipient information. An input field is displayed after creation of a message and the recipient information is input into the displayed input field. An input field is added for entering information about another recipient. The method and device allow dynamic creation or addition, or deletion, of an input field for inputting recipient's phone number or e-mail address, thereby reducing unnecessary consumption of memory space.
