摘要： PROBLEM TO BE SOLVED: To obtain a nozzle suitable for a compact gas detecting device and capable of freely adjusting its shape so as to be inserted into various sections. SOLUTION: A first wire rod provided with elasticity and a second wire rod provided with elastisity are parallelly wound on a tube body 8 made of a flexible material into a coil in such a way that the second wire rod is sandwiched by the first wire rod and that at least a part of the outer circumference becomes of a diameter to be held at the inner surface of the tube body 8. A shape holding material 9 to hold the overall shape by the rigidity of the second wire rod is inserted into the tube body 8. When a sampling nozzle 2 is bent, the first wire rod maintains the coil shape by its elasticity, the second wire rod is changed into a shape according to the bending to maintain the overall shape, and the tube body 8 at the outer circumference maintains airtightness.

摘要： PROBLEM TO BE SOLVED: To provide a tape type gas concentration measuring apparatus, which is constituted in such a way that a cassette loaded with a gas detecting tape can be exchanged with another cassette through simple operation. SOLUTION: A tape type gas concentration measuring apparatus is provided with a measuring head 12 arranged on the surface faced to the tape drawing-out port of a cassette A, a suction head 14 which is arranged on the other side of a tape carrying route opposite to the head 12 in such a state that the head 14 can be moved forward and backward against the head 12, and a cam plate 13 which moves the head 14 against the head 12 when the plate 13 is rotationally driven by means of a driving means. When the cam plate 13 is rotated in a state where a cassette holder is pressed down while the holder holds the cassette A, the suction head 14 elastically comes into contact with the measuring head 12 through a detecting tape and can make measurement.

摘要： PROBLEM TO BE SOLVED: To simplify the designation of a weight mounting position at the time of mounting a correction weight in the position other than a reference surface. SOLUTION: This device is provided with an unbalance measuring means 21 for detecting an unbalance quantity and an unbalance position in the reference surface of a wheel W, a measurement scale 5 movably provided in a case body, at least the tip of which reaches the inner part of a rim R constituting the wheel W, a weight mounting position computing means 22 for detecting the draw-out quantity from the reference position of the measurement scale 5 and a correction quantity computing means 23 for computing the weight of the correction weight in the position designated by the measurement scale 5 from the unbalance quantity measured by the unbalance measuring means 21 and the draw-out quantity of the measurement scale. Since a correction place is designated by the measurement scale 5 in the step in which the unbalance quantity relative to the reference surface is computed, the correction quantity in the designated position is computed, and accordingly the weight having a weight to agree with the correction quantity can be mounted on the rim in accordance with the measurement scale 5, thereby dispensing with the draw-out operation for re- reference.

摘要： PROBLEM TO BE SOLVED: To obtain a tape-type gas measuring device which prevents a gas from creeping during a measurement and by which the gas can be detected with high reliability, by a structure wherein the side face of a contact part in which the gas comes into contact with the measuring region of a gas detecting tape comes into contact with the edge part on the side of the unused region of the detecting tape. SOLUTION: This tape-type gas measuring apparatus which is applied to a silane-gas monitoring operation or the like uses a cassette which houses a detecting tape 9. In the cassette, a window by which the detecting tape 9 is brought into contact with a measuring head 20 comprising a contact part 21 in which an opening 24 is formed/ Slopes which are expanded and opened to the outside are formed in the edge part 10a and the edge part 0b of the window, Then, in a measurement, the measuring head 20 makes its way from the window so as to elastically press the detecting tape 9 between itself and a receiver part 3c so that air or the like which contains a gas to be detected is made to flow to the surface of the detecting tape 9. Then, the edge parts 10a, 10b of the window are sealed by the slope 21a and the slope 21b of the contact part 21. As a result, it is possible to prevent the discoloration of the detecting tape 9 in its unused region due to a reactive gas which is contained in the air or the like.
