    摘要: An improved structure of a gas sensor is provided which is designed for achieving desired crimping of an end portion of a sensor housing to establish a higher degree of gas-tight seal between the housing and a sensor element. The sensor element is fitted within the sensor housing. The end portion of the sensor housing is crimped or bent to urge the sensor element into constant abutment with an inner wall of the housing through a sealing member. The housing has an unique shape and dimensions selected to ensure the higher degree of gas-tight seal regardless of the degree of wear of a crimper and/or dimensional error of the housing.

    摘要: In accordance with the present invention, the electrophotographic toner is produced by dispersing and mixing toner components containing a fixing resin, a coloring agent and an electric charge controlling dye, and by melting and kneading the resulting mixture, which is then subjected to pulverizing and classifying. According to the present invention, fine powder generated at the pulverizing and classifying steps is reused as added to a mixture of toner components as already dispersed and mixed at the dispersing and mixing step, and the surface dye density of the electric charge controlling dye is in the range from 1.0.times.10.sup.-3 to 1.7.times.10.sup.-3 g/g, or the rate of the amount of an electric charge controlling dye present on the surfaces of toner particles to the total amount of the electric charge controlling dye, is in the range from 10 to 27% by weight. Even though repeatedly used for a long period of time, the electrophotographic toner does not lower the developer in electric charging characteristics. Further, by adding the fine powder to the mixture as already dispersed and mixed at the dispersing and mixing step, there can be efficiently produced a fine-powder regenerated toner excellent in transfer efficiency, resolution and gradation.
