Abstract: A reference time provision system using a beacon signal of a DGPS(Differential Global Positioning System) is provided to supply exact reference time by feeding back time delay generated in passing through a base station system and an antenna. A reference time provision system using a beacon signal of a DGPS is composed of a reference time output unit for generating and outputting reference time, and a DGPS unit(100) for transmitting time information together with the beacon signal on the basis of the reference time output from the reference time output unit. The reference time output unit has a calibration unit for compensating time delay generated in transmitting and receiving the time information. The calibration unit comprises a GPS clock unit(320); a DBR(DGPS Beacon Receiver,300) receiving an electric wave transmitted from the DGPS unit; a comparing unit comparing the time output from the GPS clock unit with the time received through the time information receiver; and a feedback unit feeding back the comparison result of the comparing unit to the reference time output unit.

Abstract: PURPOSE: An urushiol resin coating agent obtained by separation of urushiol from raw japanese lacquer and heat curing to give an urushiol oligomer, or epoxidation of the obtained urushiol oligomer is provided which improves flatness, hardness, heat resistance and glossiness and has excellent reproducibility. CONSTITUTION: The urushiol resin coating agent contains 28 to 90% by weight of an urushiol oligomer having an average number of 3,000 to 10,000 obtained by heat curing raw japanese lacquer, 7 to 70% by weight of an aromatic or aliphatic isocyanate compound, 0.1 to 2% by weight of a polyether modified silicon-based surfactant and 0.01 to 0.05% by weight of a catalyst. The urushiol oligomer is obtained by dissolving raw japanese lacquer in a solvent selected from n-hexane and kerosene, separating insoluble material by centrifugal separation, washing supernatant liquid with water and leaving the obtained urushiol at 100 to 140deg.C.
