Abstract:
1. A gyrocompass comprising: a liquid tank which contains a supporting liquid therein; a gyrosphere which floats in the liquid tank by means of the supporting liquid and whose central portion is rotatably supported by a center pin provided in an upper portion of the liquid tank; a gyro rotor incorporated in the gyrosphere; two dish-shaped electrodes respectively disposed at a lower portion of the liquid tank and a lower portion of the gyrosphere, and opposed through the supporting liquid; and a pair of follow-up electrodes respectively disposed in a vicinity of a equator of the liquid tank and opposed to be apart each other by 180°; and two belt-shaped electrodes respectively disposed in vicinities of equators of the liquid tank and the gyrosphere in a state that the follow-up electrodes are located therebetween, and opposed through the supporting liquid, wherein electricity is fed to the gyro rotor through the dish-shaped electrodes and the belt-shaped electrodes.
