摘要： An optical radio communication system comprising a first light transmitting system and a second light transmitting system. Each of said first and second light transmitting system comprising a transmitting means and a receiving means. Said transmitting means comprising a light emitting element positioned in a region including and surrounding a focal point of a first parabolic reflector for emitting light beams, said first parabolic reflector having an inner reflective surface for reflecting said light beams emitted from said light emitting element, and a means for driving said light emitting element with a signal to be transmitted. Said receiving means comprising a second parabolic reflector having an inner reflective surface for reflecting incident light beams, a light receiving element positioned in a region including and surrounding a focal point of said second parabolic reflector for receiving light beams reflected by said second parabolic reflector to output signals, and means for taking out information from said signals outputted from said light receiving element. In this optical radio communication system, broadband signals such as Manchester coded signals are directly transmitted on optical radio.

摘要： A wireless communication network system includes a communication controller, and a plurality of terminal devices which can communicate with the communication controller by wireless. The communication controller includes a first section for detecting absence of a received signal from any of the terminal devices, and a second section responsive to an output signal of the first section for periodically generating a nonbusy signal, which can be discriminated from another signal transmitted from the communication controller, in the absence of the received signal. Each of the terminal devices includes a third section for detecting the nonbusy signal, and a fourth section responsive to an output signal of the third section for permitting transmission from the terminal device after the nonbusy signal is received by the third section.

摘要： In an optical transmitting and receiving apparatus. an light transmitting and receiving unit includes a light emitting element, a light transmitting lens, a light receiving lens, and a photosensitive element. The light emitting element outputs light. The light outputted from the light emitting element passes through the light transmitting lens before leaving the light transmitting and receiving unit as outgoing light. The light receiving lens concentrates incoming light on the photosensitive element. A first support member is operative for supporting the light transmitting and receiving unit, and for allowing the light transmitting and receiving unit to rotate about a first axis. A first rotary mechanism connected to the light transmitting and receiving unit and the first support member is operative for rotating the light transmitting and receiving unit about the first axis. A second support member is operative for supporting the light transmitting and receiving unit on a cantilever basis, and for allowing the light transmitting and receiving unit to rotate about a second axis perpendicular to the first axis. A second rotary mechanism connected to the light transmitting and receiving unit and the second support member is operative for rotating the light transmitting and receiving unit about the second axis.
