JPS5975277A  
JPS58191932A
PURPOSE: To obtain data in a short time, by measuring the beat of a reference signal having the same frequency increasing ratio as that of an interference fringe signal at estimated acceleration due to gravity and the beat of an interfer...  
JPS57201874A
PURPOSE: To negate the operation of gravity, by establishing a simultated natural dropping movement toward the direction opposing to the gravity and forming the phenomenon of static collision with an objective. CONSTITUTION: When an equi...  
JPS5772066A
PURPOSE: To measure a direction at a high sensitivity in detection for robot operation, by a method wherein a photoconductive part, which changes direction in accordance with the direction of an operating force, such as gravity, magnetis...  
JPS5719687A
PURPOSE: To forecast effectively the occurrence of earthquakes by means of using a noninduction coil or a semiconductor element to transfer the mass wave into electric current. CONSTITUTION: A cross-type nonconduction coil B receives the...
