摘要:
The present invention relates to an organic thin film transistor which includes an organic layer comprising an organic compound facilitating the ohmic contact between a semi-conducting layer and electrodes and serving as the semi-conducting layer. The organic thin film transistor according to the present invention has excellent electric contact between the semiconductor layer and the source electrode/drain electrode, and thus can be widely used as components for electric/electronic devices. As a result, as the materials for the source electrode or the drain electrode in the organic thin film transistor, materials which are less expensive and excellent in processibility though they have a low work function as the materials can be used.
摘要:
A method for adaptively allocating resources of an uplink control channel according to a system situation is disclosed. If a base station (BS) recognizes the system situation, establishes control information for resource allocation, and transmits the control information to a mobile station (MS), the mobile station (MS) allocates resources for transmitting uplink control information using a specific block or a specific resource distribution method according to the corresponding control information. The system situation may be changed according to the number of users contained in the BS's coverage or the usage of a multi-antenna. The variation of the system situation is actively reflected so that the uplink channel resources can be effectively used.
摘要:
A gas radiation burner includes a gas supply unit for spraying a mixed gas of a gas and air; a burner body having a burner pot accommodating the mixed gas supplied by the gas supply unit and a burner housing provided on the burner pot to configure a combustion chamber; a burner mat provided over the burner pot to emit a radiant heat generated by combustion of the mixed gas supplied by the burner pot; and an air supply unit supplying air to the burner housing.
摘要:
The stack type semiconductor package module includes a lower semiconductor package having a main substrate, a chip mounted on the main substrate and electrically connected to the main substrate through a wire. An epoxy molding compound (EMC) is provided on the main substrate to cover the chip and the wire. Contact holes are formed in the EMC. A sub-substrate having protrusions coated with solder is connected to the lower semiconductor package by inserting the solder coated protrusions into the contact holes. Heat is applied to the protrusions, and the molten solder solidifies inside the contact holes. An upper semiconductor package having substantially identical structure as the lower package is then stacked on the sub-substrate.
摘要:
Disclosed are a gas burner and a method for controlling the same in which stable use is possible and combustion efficiency is improved. The gas burner includes a burner body burned by a mixture gas of gas fuel and air, a gas supplying valve supplying the gas fuel to the burner body through a gas supplying tube connected with the burner body, an air supplying fan supplying the air to the burner body through an air supplying tube connected with the burner body, and a control part controlling air flow supplied to the burner body by controlling revolution per minute (RPM) of the air supplying fan. Since an optimal air-fuel ratio can be maintained by controlling the RPM of the air supplying fan, combustion efficiency can be increased. Since a temperature of a glass can be maintained properly, life span of the gas burner can be increased and its stable use is possible.
