Title: Bus voltage stabilizing device
Inventor: ITO FUMIO
IPC: B64G1/42
Filed: 1984-09-21
Abstract: PURPOSE:To reduce the generation of the dump energy by controlling automatically the angle formed between a solar battery panel and the sun. CONSTITUTION:When the power consumption of a load is reduced, the bus voltage of a bus voltage line 15 increases. Thus the difference voltage Vdef if produced from a comparator 17, and a drive circuit 19 drives a drive motor 13. Thus the direction of a solar battery panel 11 is corrected to the sun. Then the bus voltage is reduced gradually. The drive of the motor 13 is stopped when the reference voltage is coincident with the comparison voltage through the comparator 17. On the contrary, the power consumption of the load is increased and the bus voltage is reduced on the line 15. Then the voltage Vdef is also obtained from the comparator 17. Thus the panel 11 is turned to the direction where the bus voltage increases and controlled sot hat the coincidence is obtained between the reference voltage and the comparison voltage.

Filed: 1993-08-11
Abstract: PURPOSE:To quickly and stably switch the frequency with a certain comparsion frequency independently of the channel width by providing a direct digital synthesizer which generates a comparison signal having a corresponding frequency based on the output of a voltage controlled oscillator and phase data set from the outside. CONSTITUTION:An output frequency fv of a direct digital synthesizer DDS 40 is given by fv=fo.PHI/2N. When PHI<2N is selected, the DDS 40 functions as a variable frequency divider which has a frequency division number fo/fv=2N/PHI corresponding to the set value of phase data PHI. Consequently, fo=2N.fR/PHI is true at the time of phase lock with respect to a PLL loop; but when phase data PHI is controlled by PHI=PHIo-i.DELTAPHI (i=0, 1, 2...), the output frequency fo of a voltage controlled oscillator 5 is changed by fo=2N.fR/(PHIo-i.DELTAPHI). Then, PHIis selected as a large value and DELTAPHI is selected as a very small value to arbitrarily reduce the channel step width of the output frequency fo.

Abstract: PURPOSE:To avoid collision between a re-transmission data and a new transmission data by re-transmitting a collision data efficiently. CONSTITUTION:Each time slot accessed by a peripheral station in the random access system consists of a mini-slot part and a data slot part. When a data A1(B1) is sent in a 1st slot (data slot part) of a frame 1 by a peripheral station T1(T2), the signal is sent in a mini-slot M1(M4) selected optionally in the mini- slot part. A central station C monitors the mini-slot part, and since two mini- slots are used in the mini-slot part of the 1st slot of the frame 1, it is judged that collision takes place in the slot and a re-transmission slot is assigned. The peripheral stations T1, T2 select the re-transmission slot in the order of the position of the mini-slot used by the stations themselves and send collision data A1', B1' again. When other peripheral station T3 sends a new data C1, the station selects a time slot (2nd slot of a frame 3) at which the station sends the data in random access from re-transmission use slot assign information.
