A method of manufacturing a tunable wavelength optical filter. The method includes steps of forming a first sacrificial oxide film for floating a lower mirror on a semiconductor substrate; sequentially laminating conductive silicon films and oxide films for defining a mirror region on the first sacrificial oxide film in a multi-layer and laminating another conductive silicon film to form a lower mirror; sequentially laminating conductive silicon films and oxide films for defining the mirror region on a second sacrificial oxide film in a multi-layer and laminating another conductive silicon film to form an upper mirror and forming an optical tuning space between the lower mirror and the upper mirror and etching the first sacrificial oxide film and the second sacrificial oxide film such that the lower mirror is floated on the semiconductor substrate.

There are provided a home gateway system providing an optical communication packet data interface function and a home broadcast service providing method using the same. The home gateway system is constructed to include a network processor having two Ethernet interfaces connected to a system control processor of a home gateway and an Ethernet switch having an Ethernet multicast traffic processing/IGMP snooping function based on an Ethernet L2 multicast MAC table to thereby simultaneously provide a broadcast service such as a CATV broadcast service, and an Internet data service to a plurality of hosts in a home. In case of a broadcast service, the home gateway system converts a broadcast stream into an IP multicast packet and then processes the broadcast IP multicast packet by an L2 multicast function of an Ethernet switch, thereby making it possible to directly transmit the broadcast IP multicast packet to a host without the help of the control processor.

The present invention relates to a double drawer of a refrigerator. An object of the present invention is to provide a double drawer of a refrigerator, wherein a sufficient extended length can be secured, the space usability is improved, and the durability can also be improved in spite of its long extended length. To this end, a double drawer of a refrigerator comprises a main drawer having a predetermined space defined therein for accommodating foods; an auxiliary drawer having an inner space defined therein for accommodating the main drawer, the auxiliary drawer including drawing rails for guiding the main drawer to slide in a fore and aft direction and allowing the main drawer to slide in and out; and guide rails installed in a main body of the refrigerator to guide the auxiliary drawer to slide in the fore and aft direction. According to the present invention so configured, there are advantages in that a sufficient extended length of the main drawer can be secured, and the durability can be improved since the main drawer can withstand a moment resulting from the weight of the foods accommodated in the main drawer by the extended length in spite of the sufficient extended length of the main drawer.

In a wireless data communication network, a mobile terminal is reconnected to a contents provider, when a connection established between the mobile terminal and the contents provider is interrupted or after a completion of the downloading of contents, by using return address information and contents address information including addresses of the contents provider and a web page including information relating to the downloaded contents, respectively. A WML (wireless markup language) script including the contents address information and the return address information is provided to the mobile terminal before initiating the downloading of the contents. In this way, the mobile terminal can easily be reconnected to the contents provider when the connection established between the mobile terminal and the contents provider is interrupted due to network congestion or the mobile terminal leaving the service coverage area.

The present invention relates to a door basket for a refrigerator provided on a rear surface of a refrigerator and for receiving the food. According to the present invention, there is provided a basket main body having a predetermined receiving space formed therein. In addition, a guide holder is detachably installed on the basket main body. A guide bar for supporting a side of food received in the receiving space is coupled rotatably about the guide holder. Also, an elastic member is provided in one side of the guide bar to exert an elastic force on the guide bar to be spaced apart from an upper end of the basket main body by a predetermined distance. According to the present invention, the guide bar can be easily installed to the basket main body without deformation of the basket main body. When the guide bar is installed, the guide bar supports the food received in the receiving space in a state where the guide bar is spaced apart from the basket main body by a predetermined distance. However, when the food is received in the receiving space or taken out of the receiving space, one side of the food pushes down the guide bar and passes through the guide bar, so that the food can be easily taken in and out.
