Title: Method for controlling plate-making printing plate
Inventor: OGUCHI HIDEYUKI
IPC: B41C1/10
Filed: 2000-05-15
Abstract: PROBLEM TO BE SOLVED: To accurately judge the use term of validity by evenly judging the deterioration with the elapse of time of a repeatedly utilizable plate-making printing plate. SOLUTION: Since the use state of the repeatedly utilizable plate making printing plate 54 is controlled using ID 104 and a judge level is determined to report a proper replacing period, the printing plate can be utilized for a long period without exerting effect on the finish state of printed matter by the use state of an operator (a difference between use frequencies due to a person requiring the replacement with a new printing plate a little early and a person requiring the replacement with the new printing plate a little late). The procedure performing the control of parts using the ID 104 has been performed heretofore but, herein, even if use frequency is same in the number of printing sheets or the kind of printed matter, the judge level is different.  That is, since the plate making printing plate 54 is not merely controlled on the basis of time and the use environment of the plate making printing plate 54 is estimated and the judge level is determined, the plate making printing plate 54 can be effectively utilized long without exerting effect on the finish state of the printed matter.

IPC: H04W64/00
Filed: 2000-05-25
Abstract: PROBLEM TO BE SOLVED: To obtain a positioning system capable of determining a position of a moving station itself by the moving station with a simple configuration. SOLUTION: In the system, a position information and PN signal of the base stations is transmitted to a moving station by a paging channel or down traffic signal from at least four base stations. The PN signal generated at a PN signal generator of the moving station and the PN signal from the base station are inputted into a PN signal correlative part, so that a propagation delay time ΔT is measured based on a phase difference from a receiving standard time Tu. Then a dummy distance (a distance including an error of each clock of base station, an error caused by receiver's noise, and also including every kind of error added a correcting value for error or the like occurred by moving of the moving station) is calculated by multiplexing a propagation speed (nearly equal to the light speed C) to the delay time ΔT.  A position of the moving station is calculated from the dummy distance and the position information from the base station.
