Abstract: A culturing device configured such that an isolator 2 has at least two communication ports 2dA and 2dB, and such that an incubator 4 is connected to each of the communication ports via a connecting member 114 (connection means 111). In the state where the work chamber 2a and the inside of the incubator 4 can be made to communicate with each other by opening the one communication port 2dA and a carrying-in-and-out port 4d of the incubator 4, which carrying-in-and-out port 4d is made to communicate with the communication port 2dA, the other communication port 2dB and the carrying-in-and-out port 4d of another incubator 4 are closed, and decontamination gas is supplied into the decontamination space S formed inside the connecting member to thereby decontaminate a portion exposed to the decontamination space. Thereby, the cultivating operation can be efficiently performed.

Abstract: A wrist watch-style pager prevents connection failure and/or breakdown due to attachment/detachment of a loop antenna and has a receivable frequency band which is not affected by the thickness of the wearer's arm. A U-shaped antenna structure is mounted inside a wrist band part which is part of the wrist band divided at the center fastening structure. The U-shaped structure functions as an independent antenna on at least one part of the wrist band. The antenna is buried in the wrist band part so that the two ends of its U-shaped structure face toward a page mainbody. When each of two contact pins on the ends of the U-shaped structure connect the wrist band with the pager mainbody, a terminal spring on a reception circuit substrate of the pager mainbody is pressed. This causes the receiving signal from the antenna to be conveyed to the page mainbody.
