摘要： PROBLEM TO BE SOLVED: To cope effectively with the failure time of a high-accuracy gyro by only a low-accuracy gyro. SOLUTION: In a calibration part 13, data obtained by a primary gyro device 11 and data obtained by a backup gyro device 12 are extracted at the operation time, and the difference between both data is determined by a correction operation function 131, and the difference data are memorized in a database 132 as collection data by being correlated with the data obtained by the backup gyro device 12. When the primary gyro device 11 fails, the correction data corresponding to the data obtained by the backup gyro device 12 are selected successively from among the correction data memorized in the database 132 by a gyro correction function 133, and the correction data are added to the data obtained by the backup gyro device 12.

摘要： PROBLEM TO BE SOLVED: To remarkably reduce the time and labor for production and integration concerning a separating knife constitutive group while maintaining the required fixture certainty of the separate knife constitutive group and the required rigidity of a holder for a separating knife itself. SOLUTION: A holder (31) is formed of a support arm (39) effective for fixing a separating knife (28), at least one fixed leg part (40) positionally regulated almost parallel to this support arm (39) and a web (41) for coupling the support arm (39) and the fixed leg part (40). Further, the holder (31) is produced of plastics by injection molding techniques, and the fixed leg part (40) and a support part (32) are provided with a structure for attaining a mutual form connection. As a result, the holder (31) can be coupled with the support part (32) by fitting it in parallel to a recording plane.

摘要： A method for calibrating a pressure-sensing altitude sensor of an aircraft while the aircraft is in flight. The method includes the steps of obtaining a set of reference atmospheric pressures as a function of height above a base station by affixing a reference pressure sensor to a balloon. As the balloon is released into the atmosphere, the reference sensor continuously measures the atmospheric pressures and transmits the data back to the base station while a ground-based radar disposed adjacent the base station measures the height of the balloon. An aircraft flying in a vicinity of the base station can calibrate its pressure-sensing altitude sensors by measuring the atmospheric pressure outside the aircraft and its geometric height relative to the base station and then comparing the pressure measurements with corresponding reference pressure values at a geometric height that is substantially that same as the geometric height of the aircraft.

摘要： PROBLEM TO BE SOLVED: To provide a calibration method for a sensor system capable of automatically calibrating and inspecting the sensor system without providing a new auxiliary means. SOLUTION: This method has a process for detecting characteristic data of an object by the sensor system; a process for supplying the data recognized as the stationary or quasi-stationary object in consideration of proper motion of a vehicle to a calibration unit; a process for getting a difference between model data and actually measured data of the object as an error vector; and a process for correcting the model data such that the difference becomes minimum.

摘要： PROBLEM TO BE SOLVED: To provide a top plate manufacturing method whereby a top plate can be polished appropriately even if the surface configuration of a recess in the top plate is a non-rotation-symmetry aspherical surface such as a toroidal surface. SOLUTION: A glass preform is first pressed by two forms to form a top plate 10 having on one side a recess 11 having different curvatures in two perpendicular directions, which deepens toward its center. Next, a polishing tool 15 with a projecting part 16 that almost matches the surface configuration of the recess 11 in the top plate 10 is prepared, and the recess 11 is pressed against the projecting part 16 with the two directions matching the projecting part 16. The top plate 10 and the polishing tool 15 are slid relative to each other along either of the two directions to polish the recess 11.
