Title: Method for precisely measuring high voltage
Inventor: YONEZAKI GENTA
IPC: G01R19/00
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To more accurately measure a high voltage, by detecting a moving amount of a moving electrode by a laser length measuring equipment in the order of sub-ppm. SOLUTION: A moving electrode 1 having a translating unit 1a, and a fixed electrode 2 having an electrode moving unit 2a, are disposed in an opposed state. When a voltage to be measured is applied to the electrodes 1, 2, the electrode 1 is attracted to the electrode 2 and moved. This moving distance is counted in seven ranges by a laser length measuring equipment 3 which reads the distance up to its 1/100. In this case, since the moving distance of the electrode 1 is proportional to square of its applied voltage, the applied voltage is obtained by applying the output of the equipment 3 to a square root IC circuit 4. Thus, the distance of the electrode 1 is detected by the equipment 3 in the order of sub-ppm. Thus, the voltage can be measured in accuracy of four places or more than that of prior art.

Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To improve the communication efficiency by selecting automatically a frequency hopping pattern used by a radio master station without using a server and a maintenance tool or the like and preventing the same frequency from being used between adjacent radio zones. SOLUTION: When other radio master stations of a surrounding radio zone are not entirely in operation at application of power, a radio master station selects a frequency hopping pattern number 1. When the other radio master stations of the surrounding radio zones are in operation and number of frequency hopping patterns in use is less than (n), the radio master station selects a frequency hopping pattern next to a largest pattern number among the pattern numbers in use. When the other radio master stations of the surrounding radio zones are in operation and number of frequency hopping patterns in use is (n) or over, the radio master station selects a frequency hopping pattern in use less frequently with a youngest number among the pattern numbers in use.
