摘要： The radio signal receiving device that has an input terminal for inputting an input signal and an output terminal for amplifying the signal inputted to the input terminal and then outputting the signal, comprises an insulating container comprising the input terminal and the output terminal, and an amplifier that is contained in the insulating container and amplifies the signal and then outputs the signal as the output signal. Bias voltage from one of the amplifier input terminal of the amplifier and the amplifier output terminal of the amplifier is applied to the output signal outputted to the amplifier output terminal of the amplifier.

摘要： An ultralow-temperature low-noise amplification apparatus of high sensitivity which realizes a small size, a light weight, a low electric power consumption and a low price. As the insertion loss caused by high-frequency cables and a superconducting filter installed as a first signal transmitting device before a first-stage amplifier is most responsible for any increase in the noise figure of the ultralow-temperature low-noise amplification apparatus as a whole, they are formed from a material causing only a small insertion loss to reduce the noise figure of the apparatus effectively. A high-frequency cable forming a third signal transmitting device not affecting the noise figure of the apparatus substantially is formed from a material of low thermal conductivity, so that it is possible to prevent any external heat from entering a heat-insulating container through an output connector to hold the interior of the container steadily at a low temperature and thereby keep the noise figure of the apparatus at a low level.

摘要： An electronic apparatus includes a thermally insulated vessel having a cooling part therein. Disposed inside the thermally insulated vessel are a first electronic part and a second electronic part. The second electronic part is spaced apart from the cooling part while the first electronic part is in direct contact with the cooling part, such that the two electronic parts can operate at different cooling temperatures.
