Abstract: Provided is a microwave plasma discharge lamp apparatus which includes a rectangular waveguide having a rectangular shape one end of which is closed and the other end is open and receiving a microwave through an opening to put out linearly polarized microwaves; a discharge lamp; a resonator cavity, formed in a cylindrical shape, one end of which is open, which is disposed to surround the discharge lamp, and which is made of a conductive mesh, thereby allowing the passage of the light from the discharge lamp; and a phase shifter, which has a cross-shaped waveguide opened in a propagation direction of the linearly polarized microwaves, is disposed between the other end of the rectangular waveguide and one end of the resonator cavity, and receives the linearly polarized microwaves from the rectangular waveguide to generate elliptically polarized microwaves in the cylindrical resonator cavity. The elliptically polarized microwaves discharge the discharge lamp.

Abstract: A system for multifunctional remote control is disclosed. The system comprises a remote control (100) for connecting mechanically and electrically with a cartridge (200), reading data stored in the cartridge through the first connection unit (110), storing the read data, and setting the registration of use; and a cartridge (200) for mechanically and electronically connecting with the remote control (100), receiving data from a user computer (10), storing the received data, and transmitting/receiving infrared signal to/from a controlled product.
