Title: Message encoding in variable rate
Inventor: GOPALAKRISHNAN NANDU
IPC: H04W72/04
Filed: 2001-06-05
Abstract: PROBLEM TO BE SOLVED: To identify a message group which can be used for transmitting by using previous messages. SOLUTION: As a message group contains the different number of messages, as a result, the messages from a smaller group can be expressed by using smaller bits than in the messages from a greater group. As the smallest group contains the messages accompanied by the highest possibility to be transmitted, the possibility of using the messages expressed by the smaller number of bits is maximized. The messages from the different groups are transmitted at different power level, and a receiver can determine the message group. As this result, the receiver identifies the messages by using previous messages, the power levels relating to the received messages, and the received message bits.

Title: Metallic siding
Inventor: SHIMIZU HIROKI
IPC: E04F13/12
Filed: 2001-06-18
Abstract: PROBLEM TO BE SOLVED: To eliminate waving of fitting parts at the opposite ends in the width direction of a metallic siding and such warping thereof as to expand as a whole in the longitudinal direction, in the metal siding wherein a protuberant pattern of bricks with joints or the like is formed by embossing in the intermediate part in the width direction. SOLUTION: A protuberant pattern part 3 is formed by embossing in the intermediate part in the width direction of a metal sheet, while the opposite ends in the width direction thereof are left to be flat. Thereby an elongation strain of a metal having a reverse-V-shaped section is allowed to occur in the opposite ends in the width direction, while the elongation strain is pressed to be a fold 2 by a rolling mold after the embossing. The metallic siding A is constituted with the fold 2 disposed at the fitting part 1 and thus the waving of the siding and the elongation strain of the metal that cause the warping are absorbed in a molding stage.
