Abstract: An analytical system capable of analyzing data by means of an analytical machine or tool and providing that analytical data to a computer for processing is provided. A protocol conversion radio machine is provided corresponding to each analytical machine and tool to be controlled and data can be communicated in a wireless manner between the analytical machine and tool and a plurality of computers. The protocol conversion radio machines cannot only mutually communicate with the plurality of computers but also can give and receive control signals to assist in the accumulation and transmission of analytical data between the computers and the analytical machines and tools.

Abstract: In a ventilating device for a container which comprises a container frame consisting of tubular rail members, outer ventilation holes formed through the outer wall of the rail member so as to be exposed to the outside of the container, inner ventilation holes formed through the inner wall of the rail member so as to be exposed to the interior of the container, and a ventilation channel defined inside the rail member so as to connect the inner ventilation holes and the outer ventilation holes, this ventilating device further comprises a first groove which is formed in the inner wall of the rail member so as to extend along the longitudinal direction of the rail member, and a second groove which is formed in the outer wall of the rail member so as to extend substantially parallel to the first groove, the lower wall of the first groove and the upper wall of the second groove defining a part of the ventilation channel.
