An image capture and transmission system includes first and second imaging devices. The method includes determining the levels of a trimethylamine in a biological sample obtained from the subject. By forming the condensation unit that condenses the vaporized working fluid in the upper end portion relative to the working fluid filled in the hollow portion of the housing, the heat exchange effect of the working fluid may be maximized. Further, the amount of said first information is smaller than the amount of said second information, and the first information is embedded more deeply in the image than is the second information. Thus, the non-volatile semiconductor memory device capable of retaining charges as information stably is attained. The thickness of the underlayer is smaller than three times of the predetermined opening width.
