A biological information-measuring apparatus which is situated in a shielded room and includes measuring means for measuring biological information of a subject arranged and supported between a pair of supporting pillars of a double housing type support, wherein H-cross section members are combined to form a lattice-like supporting frame, and the bottoms of the supporting pillars are anchored to the members forming the supporting frame.

Biological information-measuring apparatus

A control apparatus for maintaining constant the temperature and pressure of the vapor phase in a very low-temperature controlled liquefied gas container includes a pressure sensor, a temperature sensor, two electromagnetic valves, and a refrigerator. When operation of the refrigerator disturbs measurement at low temperature, the refrigerator is stopped. Gas vaporizes from a liquid phase, and gas is discharged from the container. In this manner, the temperature and pressure of the liquefied gas in the container can be maintained constant. After measurement, the liquid level in the container will be lowered by evaporation, so that the liquefied gas is supplied to the container. In this manner, the liquid level in the container can be maintained constant.
