Abstract: PURPOSE:To prevent the mixing of signals from a material rod and a seed crystal, and to improve the precision of control by limiting the scanning range of an image sensor within the molten zone in the titled controlling method. CONSTITUTION:A single crystal is manufactured by condensing the infrared radiation from infrared lamps 4 and 5 to form a molten zone 8, and lowering a seed crystal 7 and a material rod 6 while rotating the crystal and the rod in the direction shown by the arrows (symbols 1 and 2 are rotary ellipsoidal mirrors, and Fa, Fb, and F2 are their focuses). Then the outputs obtained by scanning vertically the molten zone 8 are compared with a reference voltage, made into two values, and stored. Meanwhile, the volume of the molten zone is calculated by using said values to obtain the variation from the ideal volume, and a specified calculation is carried out together with the variation obtained m-times before. And the power supplied to the infrared lamps and/or the supplying velocity of the material rod are controlled by using the obtained value.

Title: Attitude determination of triaxially stable satellite
Inventor: OKANUMA TORU
IPC: G01C21/24
Filed: 1989-08-25
Abstract: PURPOSE:To use a sensor characterized by a low cost and easy handling and to make it possible to change the characteristics of estimated errors by providing an earth sensor for detecting the attitude angles around the axis X and the axis Y, providing a judging device for outputting a pulse signal at a time when the sign of the attitude angle around the axis Y is reversed, and providing a ground command data processor. CONSTITUTION:A detector 1 for an angle around the axis X of an earth sensor detects the attitude angle around the axis X. A detector 2 for an angle around the axis Y of the earth sensor detects the attitude angle around the axis Y. The detected angle signal of the detector 2 is inputted into a judging device 9. A pulse signal is outputted at a time when the sign of the signal is reversed. A ground command data processor 30 decodes a ground command and outputs the numerical values for constants K1 and K2 for a constant multiplying integrator 11 and a constant multiplyer 12. Thus the constants K1 and K2 are changed. Thus the cost of the apparatus for use can be made low, and acquisition of the attitude angle can be handled with a simple algolithm. When the constants of the integrator 11 and the multiplier 12 are changed by the ground commands, the large initial estimation error can be brought into zero quickly. At the same time, excellent estimating accuracy with almost no effects of the output noises of the angle detector is obtained.
