Inventor: DUVAUT PATRICK
IPC: H04L5/02
Filed: 2000-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a multiple accessing method in one point/multiple point communication network. SOLUTION: This method includes a step in which each inherent variable ρi is allocated to each network terminal Ti and a next step in which the first allpass filtering operation with respect to at least one oversampled symbol extracted from upward information transmitted from the Ti and z conversion with respect to a received oversampled symbol stream for a central station to identify the oversampled symbol are carried out, and the z conversion is evaluated with the ρi allocated to the Ti to perform filtering. The allpass filtering operation has such a z conversion transfer function that a zero point corresponds to each of the inherent variables allocated to all of the network terminals other than the inherent variable ρi allocated to the Ti. A transmitter and a receiver for carrying out the method are also introduced.

Title: Method for manufacturing modified lumber
Inventor: KASHIMA MICHIO
IPC: B27K3/02
Filed: 2000-10-17
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing worked lumber wherein worked lumber having sufficient flame retardance can be obtained by a simple process. SOLUTION: After providing a permeation hole in a lumber by laser beam machining, the lumber is permeated by a silicate compound solution containing alkali silicate, colloidal silica and the like. Thereafter, by liquefying acid anhydride gas (carbon dioxide and the like) into the silicate compound solution in the lumber, the silicate compound is allowed to gel. Thereby, the permeation hole can be easily provided in a higher precision than conventionally. Besides, since a higher impregnation rate is indicated and a permeation speed is larger in comparison with the lumber without providing the permeation hole, the permeation rate at least equal in quality thereto can be obtained in a processing time of about 1/2 to 1/40 time of the lumber without providing the permeation hole because of large permeation speed.  Consequently, the permeation property and permeation efficiency of silicate compound are improved, and the modified lumber to which properties such as flame retardance and the like are imparted can be more effectively manufactured.
