A radio communication apparatus capable of, in a network in which communication may be performed by simultaneously using a plurality of communication paths, improving (e.g., extending) the operating time of the whole network are provided. A radio communication apparatus includes a power-supply information management unit configured to manage power-supply information of another radio communication apparatus for each of N redundant communication paths (N is an integer equal to or greater than two), and a communication management unit configured to perform switching, based on an amount of traffic to be transmitted and the power-supply information, between communication using n communication paths (n is an integer no smaller than two and no greater than N) among the N communication paths and communication using m communication paths (m is an integer no smaller than one and smaller than n (i.e., m&#x3c;n)) among the N communication paths.

A non-limiting example game apparatus includes a display device, and a card display screen including an image of a card object is displayed on the display device. The image of the card object is constituted by a character image arranged in the front most and a composite image that is arranged at a back thereof, and with the composite image is obtained by combining a color change image, a background image and a pattern image. The color change image includes a plurality of polygons, and a color of each of vertices is set so as to cyclically change according to an attitude of the game apparatus and respective vertices positions of the plurality of polygons. The color change image and the background image are combined with each other, so that brightness of the background image cyclically changes according to the color of the color change image that cyclically changes.

A license administration device manages grant or denial of each optional function in a plurality of licensee devices. The licensee device stores key information encrypted with a cipher key so as to issue a license change request activating or restricting the predetermined optional function. Upon receiving a license change request restricting the predetermined optional function, the license administration device overwrites the key information of the licensee device with a default key. Subsequently, upon receiving a license change request activating the predetermined optional function, the license administration device applies an upgrade key to the key information of the licensee device. The default key or the upgrade key can be decrypted using a cipher key unique to the licensee device. The license administration device manages the licensed maximum for the predetermined optional function and reflects an increment or decrement to the licensing maximum by applying the default key or the upgrade key.

License administration device and license administration method

A license management device causes a wireless device to enter a state in which all functions are restricted by overwriting key information of the wireless device with a default key specific to the wireless device. A key generating device generates an upgrade key specific to the wireless device, and transmits the update key to the license management device. The license management device can release a restriction of a function in the wireless device by applying the upgrade key to the key information of the wireless device overwritten with the default key.

A semiconductor memory device according to the present invention has a plurality of memory cells of the one-transistor and one-capacitor type, and a plurality of bit lines coupled to columns of the memory cells, respectively, and disposed in an insulating film over the memory cells, and a common upper electrode is shared by the storage capacitors of the memory cells and has shield portions interposed between the bit lines, so that the adjacent bit lines are less liable to be capacitively coupled by virtue of the shield portions, thereby allowing data bit signals to propagate without any undesirable influence of the adjacent bit lines.

Semiconductor memory device having bit lines less liable to have

This invention relates to a method for electrolyzing an alkali metal halide aqueous solution in a three-chamber horizontal type electrolytic cell which comprises a top cathode chamber bounded by a cation exchange membrane, a middle chamber, and a bottom anode chamber bounded by a diaphragm. Halogen gas and dilute alkali metal halide solution are taken out of the anode chamber in such a manner as to make the anode chamber work as a gas chamber.
