Title: Satellite communication system
Inventor: TACHIKAWA KENICHI
IPC: H04B7/005
Filed: 1987-12-28
Abstract: PURPOSE:To reduce the cost of the title system by simplifying the constitution of each earth station by performing central control by requesting the change of transmission output based on a result in which the change of a level by the attenuation of a wave between the earth stations performing communication is detected. CONSTITUTION:It is assumed that rainfall is generated on a wave transmission path and rainfall attenuation between a communication satellite 1 and the earth station 3 goes to (alpha), the rainfall attenuation between the communication satellite 1 and the earth station 4 to (beta), and the rainfall attenuation between the communication satellite 1 and a central control earth station to (gamma). To compensate the rainfall attenuations (alpha), (beta), and (gamma), a signal to increase the transmission output by (alpha+f<-1>(beta)) is sent from the central control earth station 2 to the earth station 3, meanwhile, the signal to increase the transmission output by (beta+f<-1>(alpha)) is sent to the earth station 4. Each of the earth stations 3 and 4 obtains required transmission output by sending the signal from a request allocation multiple connection(DAMA) controller 38 to a variable attenuator 41 on an output side. In such a way, it is possible to make the installation of a wave attenuation monitoring device at each earth station unnecessary, which simplifies the constitution.

Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To suppress the oscillation phenomena of DC voltage by the LC resonance of a DC power source to make the voltage stable DC voltage by detecting the ripple components of DC voltage and compensating the reactive current components of the AC output current so that it may suppress ripple voltage. SOLUTION: When the DC voltage Vdph between the p and n of a DC power source ripples, a reactive current compensator 30 outputs compensation signals Iqc in high frequency region from which low frequency region including the DC of low frequency or under including the DC of specified frequency or under of the ripple components is removed. They are added an active current standard Iqr through an adder 33. Hereby, if the DC voltage between P and N ripples, the active current components of AC currents Iu, Iv, and Iw outputted from an NPC inverter 5 are compensated so as to suppress the voltage ripple. As a result, the ripple of DC voltage between P and N can be suppressed.

Title: Measurement of partial electric discharge
Inventor: ENDO TAKESHI
IPC: G01R31/12
Filed: 1988-12-28
Abstract: PURPOSE:To improve measurement sensitivity by measuring a partial electric discharge in the manner of detecting an intermediate frequency signal which is produced by mixing a signal having the frequency swept at a specified cycle to a high frequency pulse signal based on the partial discharge. CONSTITUTION:The high frequency pulse based on the partial discharge appeared as a potential difference on both ends of detection impedance 6 is attenuated to a specified level in an attenuator 8 after passing through a high- pass filter 7. An output of the attenuator 8 is amplified in an amplifier 9 and mixed with a local oscillating signal coming from a local oscillator 15 by a mixing device 11. As a result, the intermediate frequency signal (beat signal) is outputted and detected 13 after amplified by the amplifier 12. Since the frequency of the local oscillating signal in the detected signal is being swept, this detected signal is the one corresponding to the high frequency pulse with the frequency range corresponding to the sweeping width, and converted to a digital signal in an A/D conversion circuit 14. This digital signal is processed in a signal memory processing part 10, and a decision of the partial discharge is made by the size and the quantity per unit time then displayed 16.
