The invention relates to the novel cotton variety designated 04T067. An associative word unfolding processing unit acquires associative words in association with the query word held in the query word holding unit with reference to an associative word dictionary. Since a guide tube having a smaller diameter than that of a pipe line to be repaired can be used, a sufficient gap is formed between the guide tube and the manhole, thereby allowing the operator to freely access the manhole during the lining operation for inspection and confirmation of a lining situation. The PEEP valve provides positive gas pressure to a patient’s lungs, requiring a predetermined exhalation gas pressure to be exceeded before releasing exhalation gasses into the atmosphere.
