摘要： A positioning device of a position sensor that does not require re-positioning and re-fastening at the time of mounting the position sensor. A positioning tool provided with a driving section and a positioning section is mounted on a position sensor. Then, positioning projections of the positioning section are engaged with neutral position grooves. In this state, the positioning section is rotated by the driving section so as to have the position sensor rotated together until the R-contact turns ON, so that an angle from N to R, i.e. from a neutral position to a reverse contact ON position is measured. Thereafter, the positioning section is rotated in an opposite direction to measure an angle from N to D, i.e. from a reverse contact OFF position to a drive contact ON position. Based on the measurement result, the positioning section is re-rotated by the driving section to move the position sensor to a proper neutral position. The position sensor is fastened in this condition.

摘要： An inhibitor to suppress or inhibit the viscosity increase of a hydrocarbon, e.g. in a bottom section of an oil quench tower, featuring the use of a sulfonic acid and/or its salt as an effective inhibitor composition, which may optionally contain a polymerization inhibitor including one or more inhibitors selected from the group of aromatic amines, phenols and dialkyl hydroxyl amines. Furthermore, the method to inhibit the increasing viscosity of hydrocarbon, e.g. in a bottom section of a tower, may be accomplished by adding the hydrocarbon viscosity inhibitor to the feed oil, reflux oil or directly to the tower bottom oil in the tower. Such an oil quench tower is used for an olefin production process in which the hydrocarbon may include naphtha, light oil, natural gas, liquefied natural gas, etc. in the raw material.
