Abstract: PURPOSE: To make it possible to rotate an output shaft in one direction irrespective of the rotational direction of an input shaft, by arranging, between two bevel gears on the input side and the input shaft, respective one-way clutches whose transmission directions are opposite each other.  
     CONSTITUTION: The bevel gear 16, 16' are mounted on an input shaft 12 which is included in a power transmission 10 and is rotatable forwardly or backwardly, one bevel gear 20 on the output side is mounted on an output shaft 12 which can rotate only in one direction, and one-way clutches 24, 24' are mounted between the bevel gears 16, 16' and the input shaft 12. For example, if the input shaft rotates in a direction of d 1 , the output shaft is rotated in a direction of d 3  while an outer wheel 32' of the one-way clutch 24' rotates freely clockwise with respect to the input shaft 12. Thus in any case where the input shaft 12 rotates forwardly or backwardly, the one-way clutches 24, 24' are automatically switched to rotate the output shaft 14 in one direction at all times.

Abstract: PURPOSE:To prevent corrosion and clogging caused by the dew condensation of mois ture and acidic components in gas to be measured by providing an ejector-gas feeding pipe in a heating furnace in an exposed pattern, heating the ejector gas, and obtaining high temperature in the vicinity of a blowing port. CONSTITUTION:A probe transmitter is attached to a furnace wall 52 of the flue of a heating furnace. A sensor part 8 for detecting the concentration of gas is contained in a terminal box 10 of the transmitter. When ejector gas is blown out of a blowing port 20, the vicinity of the ejector 6 becomes negative pressure. Gas to be measured in the flue 22 is sampled through a sampling port 16 ad flows in the directions of an arrows A and B. The gas is supplied into the sensor part 8. The ejector gas supplied through a feeding port 7 passes through an exposed part 1b which is wound around the outer surface of a gas sampling pipe 3 and a linear exposed part 1c in a spiral pattern. The ejector gas is heated by heat exchange with high-temperature atmosphere in the flue, and the temperature is increased. The ejector gas is blown out of the blowing port 20 through an embedment part 1d. Therefore the temperature in the vicinity of the blowing port 20 becomes high. Thus corrosion and clogging caused by the dew condensation of moisture and acidic components in the gas to be measured can be effectively prevented.
