Title: Satellite communication system
Inventor: TAKAHASHI YASUO
IPC: H04B7/15
Filed: 1987-06-05
Abstract: PURPOSE:To reduce the weight and power consumption by superimposing a communication signal onto a base band of a video signal during the transmission of a television signal to send the result to the 1st repeater and giving the communication signal to the transmission system of a television signal at the stop of the transmission of the television signal so as to switch the transmission frequency of the transmission system and to send it to the 2nd repeater. CONSTITUTION:In sending a communication signal during the transmission of a television signal, after the communication signal is modulated by a communication line modulator 20, the result is sent to the 1st changeover switch 34. Since the 1st changeover switch 34 is thrown to the position of a contact (a) at the transmission of the television signal, the modulated communication signal is sent to a multiplexer 12 and the signal is multiplexed to the base band of the video signal together with a voice modulation signal. On the other hand, while the earth station stops the transmission of the television signal, since the 1st and 2nd changeover switches 34, 35 are both thrown to the position of a contact (b), the transmission power controller provided with a power amplifier 17 of a conventional satellite communication earth station is controlled. Thus, the weight and power consumption of the equipment are reduced.

Title: Current differential relay
Inventor: ODA SHIGETO
IPC: H01H47/14
Filed: 1989-06-05
Abstract: PURPOSE:To avoid transient reaction by using a self-terminal current data at a time earlier than the current data of a counterpart terminal for the suppressed current operation. CONSTITUTION:The current of a power transmission line 1 is detected by a CT2, digitally converted and transmitted to a counterpart terminal by a communication device 11 through a communication coupled circuit 7 for transmission, while it is sent to a differential determination circuit 10 by delaying it through the 1st delay circuit 9 and the 2nd delay circuit 12. The differential current and suppressed current are found from the current of the counterpart terminal sent out from the counterpart terminal through the communication device 11 and a communication coupled circuit 8 for receiving. The delay circuit 9 compensates the transmission lag in the current signal of the counterpart terminal, the output of which is used for the operation of the differential current. The delay time of the 2nd delay circuit 12 is shorter than that of the 1st delay circuit 9 and is used for the operation of the suppressed current. The suppressed current thereby rises earlier than the response of the differential current, so that transient reaction can be avoided.

IPC: F16H61/04
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To suppress a speed change shock by obtaining early information estimating the initial hydraulic change. SOLUTION: A rotation sensor 52 is connected to an arithmetic circuit 54 calculating a change factor (two times difference value of input shaft rotational speed Nt) Δ2Nt of a change factor of an input shaft rotational speed Nt.
