Abstract: In a lighting apparatus using microwave, a lighting apparatus using microwave including a resonator excluding microwave and transmitting a light, a waveguide placed at an internal domain of the resonator and transmitting the microwave, a microwave generating means installed at the side of the resonator and oscillating microwave into the waveguide, and a bulb placed at the center of the resonator and emitting light by generating a plasma by the microwave transmitted through the waveguide is capable of miniaturizing a lighting system and at the same time improving a lighting efficiency.

Abstract: Data service communication system, and method for making data service in the communication system are suggested. A particular service option is defined in advance for a fast data service between CDMA mobile stations belonging the same network. When an origination mobile station requests a call for the data service according to the particular service option, an MSC sets up a data traffic path between the origination mobile station and the destination mobile station according to the service request. A data is transmitted between the origination mobile station and the destination mobile station through the set up data traffic path. Accordingly, a load on the MSC is reduced and a fast data service can be made because the data service is made between the mobile stations within the same network without the IWF.

Abstract: The induction cooking apparatus includes an input filter for filtering supplied power, a first inverter module having a first working coil, a second inverter module having a second working coil, and a common switching section. The common switching section and the first and second inverter modules are connected in series with the input filter, and the first and second inverter modules operate cooperatively with the common switching section to energize the first and second working coils.
