IPC: G01C19/72
Filed: 1991-07-03
Abstract: PURPOSE:To reduce the zero point drift of an optical fiber gyro by installing depolarizing means adjacent each other on an optical path coupled to a phase modulating means. CONSTITUTION:Light output from a light source 1 is bifurcated by a coupler 2 and is input to a coupler 5 after passing through a polarizer 4 and is uniformly bifurcated. The light of an optical path 105 travels clockwise through an optical fiber coil 6 and is depolarized and input to a depolarizing means 9 through a phase modulator 7 and re-deporalized and input to the coupler 5 from the opposite direction. The light of an optical path 109 travels in the opposite direction and is input to the coupler 5 after propagating clockwise within the means 9, the modulator 7, the means 8 and the coil 6 and is coupled to the light wave bifurcated beforehand and then propagates in the opposite direction and is input to a photodiode 3 and converted into an electric signal. Because the light is depolarized by insertion of the depolarizing means 8,9 into a sensing loop in order to reduce errors in rotation output, fluctuations in the polarized state are very small and the zero point drift of the rotation output of a gyro is reduced.

Title: Paper feeding device
Inventor: OKADA TADASHI
IPC: G03G15/00
Filed: 1992-06-22
Abstract: PURPOSE:To prevent lowering of paper feeding capacity due to change of humidity. CONSTITUTION:Humidity in the neighbourhood of a sheet feeding table 17 is measured by a humidity sensor 50. When humidity becomes high, a control part 51 outputs a drive signal to increase rotating speed to a servo motor 38. Rotation of an air intake fan 37 and an exhaust fan 41 is increased. As the amount of air sucked from a conveyor belt 30 increases, the amount of air exhausted from an air supply nozzle 40 increases. Suction force of the conveyor belt 30 increases, and sheet separation force of a separation part 32 increases. Consequently, it is possible to carry out stable feeding of even a sheet humidified and grown heavy without causing paper feeding failure and double feeding.
