Title: Method for determining attitude of three-axis stablizing satellite
Inventor: OKANUMA TORU
IPC: G01C21/24
Filed: 1989-06-20
Abstract: PURPOSE:To obtain the attitude determining method which uses an inexpensive, easy-to-use sensor and requires no special data processing by providing an earth sensor which detects attitude angles around an X and a Y axis and a decision device which outputs a pulse signal when the attitude angle around the Y axis detected by the sensor is inverted in sign. CONSTITUTION:An angle detector 1 detects the attitude angle around the earth sensor X axis and an angle detector 2 detects the attitude angle on the earth sensor Y axis. The decision device 9 inputs the detected angle signal of the angle detector 2 and outputs the pulse signal at the time when the signal is inverted in sign. Thus, the angle detector 2 and decision device 9 are used to find the position on the orbit where the straight line connecting the earth center and satellite crosses the direction of the sun at right angles automatically on a board, and the output of the angle detector 1 at this point of time is equal to the attitude angle around the X axis, so a device in use can be constituted at low cost and the attitude angles are found by simple algorithm.

Abstract: PURPOSE:To form a visible image of high quality by forming a pattern in a state where the surface of a dielectric and a conductive surface are exposed to the surface of a developing roller, and electrostatically charging the dielectric to have a reverse polarity to the electrostatically charged polarity of the toner. CONSTITUTION:The conductive roller 10 of the developing roller 5 is constituted of an aluminum pipe, and grooves are formed in double-cut state by performing square groove knurling work to the surface of the roller 10. After applying flouroresin on the surface, cutting work is performed to the surface so as to expose the conductive surface 12 and the surface of the dielectric 11. Then, the dielectric 11 of the developing roller 5 or on the surface of a toner carrier consisting of a belt 105 is electrostatically charged to have the reverse polarity to the toner 4. In such a case, it is possible that the toner used for development is attracted to the conductive surface to be carried by electrostatically charging the dielectric 11 so as to have the same polarity as the electrostatically charged polarity of the toner 4. Therefore, the necessary amount of toner which is completely electrostatically charged is carried to a developing area and the visible image with desired density is formed, then the toner is dispersed in the developing area.
