Abstract: The development of an alternate refrigerant composition which is free from a possibility of causing depletion of the ozone layer and capable of maintaining the performance of a conventional refrigerating circuit without modifying the circuit is desired. An object of the present invention is to provide such a refrigerant composition and a refrigerating circuit using the refrigerant composition. A refrigerant composition of the present invention comprises R245fa (CF3CH2CHF2), R125 (CHF2CF3), R508A (R23/R116:39/61) and R14 (tetrafluoromethane: CF4). Thus, the refrigerant composition has no possibility of causing depletion of the ozone layer. Further, since the composition is noncombustible, possible combustion can be prevented even if it leaks.

Abstract: There is provided a medicine feeding device which can apply uniform tension to wrapping paper wound in a roll state to wrap a medicine. The medicine feeding device comprises a tablet case which stores a medicine, and the wrapping paper wound in the roll state, wraps a medicine discharged from the tablet case in wrapping paper 72, and comprises a tension application mechanism 113 which applies predetermined tension to the continuously pulled-out. wrapping paper. This tension application mechanism is constituted to freely move up-and-down, and to apply tension to the pulled-out wrapping paper by its own weight.

Abstract: To provide a CO2 incubator capable of accurately controlling the CO2 gas concentration in an incubation space and quickly coping with a sudden change of CO2 gas concentrations in the incubation space.

Abstract: To provide a preserving system capable of re-using vaporized nitrogen, and moreover, capable of always cooling the specimens at a predetermined temperature or lower. The preserving system comprising a cylinder and the preserving vessel which is supplied with liquid nitrogen from this cylinder, is provided with a Stirling refrigerator and a condensing chamber arranged outside of said preserving vessel, and the gas phase part of this condensing chamber is made to communicate with that of said preserving vessel and also the liquid phase part is made to communicate with that of said preserving vessel, and further the cooling part of said Stirling refrigerator is arranged in said condensing chamber, therefore, the nitrogen vaporized in the preserving vessel is cooled by the cooling part of the Stirling refrigerator in the condensing chamber and liquefied again, and so this liquid nitrogen can be reused for cooling the preserving vessel.

Abstract: The present invention intends to let the medicine fall regularly, by eliminating the static electricity charged on the medicine in the medicine case.
