Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To compensate error resulting from disturbance with no repeatability by converting the position error of a satellite containing a spacecraft into a mirror control signal, and conducting the fine control of a mirror position control. SOLUTION: A ground control computer 1 obtains data from an image system 4 periodically, renews the attitude position data of the spacecraft periodically, and estimates the position of the spacecraft in the next period. A fixed star sensor array 5 offers the instantaneous position data to an embarkation control computer 2 directly, and the position data is used for computing error produced by the latest renewal from the ground station 1. A detection data is added to an estimation data to produce a signal expressing the same so as to be used for the further control of the spacecraft attitude position, and the error caused by an arbitrary disturbance is compensated. The fixed star control computer 2 converts computed error based on the data from the fixed star sensor 5 into the control movement of a mirror system 6. Thereby, the accumulation of the image positioning error is avoided.

Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To obtain an output waveform without distortion by connecting nodes of pre-stage and post-stage amplifier circuits to one of a couple of potential points via respectively nonlinear loads whose bias voltage versus bias current ratio at a DC operating points and whose impedance in the case of AC small signal operation differ from each other. SOLUTION: A pre-stage amplifier circuit 10 employing series feedback resistors R3, R4 is used for a pre-stage and diode-connected transistors(TRs) D1, D2 are used for a load 11. On the other hand, a post-stage amplifier circuit 50 employing parallel feedback resistors R7 , R8 is used for a post-stage. A voltage signal received by input terminals 1A, 1B of the pre-stage amplifier circuit 10 is outputted to nodes N1, N2 as current signals, which are used for input signals to the post-stage amplifier circuit 50. Then voltage signals are outputted at output terminals 2A, 2B of the post-stage amplifier circuit 50. Since the impedance in the case of a small signal input is low because of the ON-resistance of the diodes, disturbance in waveform or the like is controlled without changing the operating point with respect to the voltage level at the nodes N1, N2.

Title: Device and method for compensating temperature of laser diode
Inventor: TATSUHIRO OTSUKA
IPC: G11B7/125
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To control the output power of a laser diode according to the temperature fluctuation. SOLUTION: The differential voltage between the voltage corresponding to the output power of a laser diode 101 and a reference voltage 105 is generated as a control voltage which is corrected by taking the output power into account by using two up/down counters 106 and 109 and impressed upon the diode 101 and, when the level of the differential voltage becomes an overflow or underflow in the first up/down counter 106, the corrected control voltage is impressed upon the diode 101 in an interlocking way with the second up-down counter 109. Therefore, a stable luminous efficacy can be obtained, because the control voltage which is corrected by sufficiently taking the luminous efficacy of the diode 101 into account is outputted, and, in addition, the control deviation can also be reduced.
