Abstract:
PROBLEM TO BE SOLVED: To provide an exhalation collecting tool capable of surely collecting an alveolar air with a simple operation. SOLUTION: When the exhalation from a subject is collected, at first, a clipping part 113 of an exhalation introduction part 11 is clamped by fingers of one hand and an air stream to a second check valve 13 is regulated. Next, the subject exhales the air to the exhalation introduction part 11. This exhaled air passes through a first check valve 12 and is collected by a first exhalation collecting part 14. This collecting operation of the first exhalation collecting part 14 continues for a while. When the air in the mouth and the upper part of trachea is completely exhaled, the fingers are removed from the clipping part 113. The air continuously exhaled afterward flows to a second check valve 13 side without passing through the first check valve 12. By this, the air left behind (alveolar air) among the exhaled air is collected in a second exhalation collecting part 15. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide vegetation blocks capable of definitely growing plants on the face of slope of a road or the like, and greening and collapse prevention method for the face of slope of road or the like by using the vegetation blocks. SOLUTION: The vegetation block 20 to be embedded to the face of slope 10 of a road contains old, used paper, fertilizer and fly ash. Here, the old, used paper is capable of enhancing the strength of vegetation block 20, and the fly ash improves the water absorption and water retainability, and further the fertilizer functions as noulishment for plants. By using these vegetation blocks 20 as the vegetation basic materials, the plants can be definitely grown on the face of slope 10 such as roads or the like. COPYRIGHT: (C)2003,JPO
