Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To receive ground signals in up/down directions of a train and to provide information by transmitting the signals in both directions with different frequencies which do not mutually affect each other through the use of one coaxial cable. SOLUTION: When the train 2 can travel to the up/down directions, a video signal V1 is modulated by a ground light transmitter 10.

It is received by a light receiver 30, is demodulated into the signal V1 in a demodulator 42 through the coaxial cable 50 and is displayed on a monitor 44. When the train travels in the opposite direction, a video signal V2 inputted to a light transmitter 12 is converted into the high frequency signal of the frequency f1 and is inputted to an up-converter 46. Then, it is converted into a high frequency f2 which does not give interruption even if the same transmission path is used, it is returned to the frequency f1 in a down converter 36 through a demodulator 32 and it is outputted to a monitor 34 as the video signal V2.  Thus, information received in both the travel directions can be received by respective driving stands only by laying one cable 50 in the train 2.

Filed: 1990-11-13
Abstract: PURPOSE:To improve antenna efficiency and a side lobe characteristic by constituting a triplet feeder by means of sandwiching the feeder with first and second conductor plates. CONSTITUTION:A circular opening 22 is piercingly provided in the conductor plate 20 which functions as a ground conductor and a radiation element in a cross dipole-state 24 is set in the opening 22.
