Abstract: The storage case has a structure in which a sample storage case (S) contained in a storage case is cooled and held at a low temperature by a Stirling refrigerator. A detection element is disposed in a room-temperature area of the storage case. The chemical or physical property of the detection element varies when a contaminant adheres to the detection element. Entrance of a contaminant into the storage case can be checked by contactlessly checking the detection element from the outside of the storage case. The storage case includes a server for receiving the result of the check from the detection device, storing the result, and setting up connection via a communication line to at least two out of a terminal operable by the forwarder, a terminal operable by the carrier, and a terminal operable by the recipient to transmit the result to the two.

Abstract: In the valve, fuel, flowing down as a valve side flow along the side of the valve, further flows down toward an orifice plate through a fuel path which closes and opens upon forward and backward movement of the valve, and is injected as a mist from each orifice. The valve moves forward and backward by sliding on a valve surrounding portion through a guide portion constituted by plural sliding guides arranged between the valve and valve surrounding portion. Since the sliding guides are tapered from the valve to the surrounding portion, the side flow from the guide portion has a flow velocity distribution biased toward the surrounding portion.
