    摘要: An optical network for bi-directional wireless communication is disclosed. The optical network includes a remote antenna unit for converting a downlink optical signal into a downlink radio signal, transmitting the downlink radio signal wirelessly, and converting an uplink radio signal received wirelessly into an uplink optical signal. An optical line is used as a transmission medium of the downlink optical signal and the uplink optical signal. The optical network also includes a central base station including a circulator linked to the remote antenna unit through the optical line, so that the central base station outputs the downlink optical signal to the remote antenna unit through the circulator and detects the uplink optical signal inputted through the circulator.

    摘要: A thermoelectric refrigerator/warmer using no external power, and a refrigerating/warming method are disclosed. A natural energy such as the solar energy is utilized so as to make an external power needless. Thus a thermoelectric device is made to convert the natural energy into electric power based on the difference between the internal and external temperatures, and this electric energy is converted again into a thermal energy by means of a peltier device, thereby varying the internal temperature of the apparatus. An outer part 4 of a thermoelectric device 3 is attached on the side face of the refrigerator/warmer, and an inner part 5 of it is attached on a bottom plate 7 of the refrigerator/warmer. Thus a thermoelectromotive force is generated based on the temperature difference between outside and inside of the refrigerator/warmer. The voltage thus generated is supplied to a peltier device 6 to cool or heat the bottom plate 7. In this manner, the thermoelectric refrigerator/warmer can be operated even without using an external power.
