    摘要: A mechanical seal comprises, in addition to a rotating seal element, a stationary seal element, and a support ring: means for securing the support ring to a rotating shaft in such a manner that, between a casing and the shaft, the ring remains nonrotatable by the shaft but can travel axially following any axial movement of the shaft. The securing means comprises nonrotational stop means located between the casing and support ring and means located between the ring and shaft to permit the both to rotate relative to each other but keep them from moving axially. The nonrotational stop means is a combination of pins and holes, key ways and keys, or the like, and the means located between the ring and shaft to permit the both to rotate is either a pair of rolling bearings or a plurality of journal bearings plus a thrust sliding bearing.

    摘要: An apparatus for measuring the content of hydrogen dissolved in a molten metal, comprising an immersion head immersed within a batch of the molten metal to bring an inert gas into contact with the molten metal, an inert gas circulating device connected to the immersion head and having gas passages cooperating with the immersion head to form a closed circulatory path for circulating the inert gas a plurality of times through the path to and from the immersion head. The apparatus further comprises a hydrogen gas content measuring device connected to the gas passage for measuring the hydrogen-content of the inert gas flowing through the gas passage, the measuring device comprising a first measuring cell connected to the gas passage and having therein an electric resistance wire exposed to the circulated inert gas containing the hydrogen picked up from the molten metal, and further comprising a second measuring cell filled with atmosphere whose thermal conductivity is substantially equal to that of the inert gas. The measuring device includes a housing block which has portions to define a vacuum chamber surrounding each of the measuring cells in order to thermally separate the cell from the atmosphere surrounding the measuring device. The vacuum chambers for both cells are connected to each other and to a vacuum source. The housing block may be a cylindrical member of metal connected to an evacuation pipe.

    摘要: An oil-cooled type screw rotor assembly having a female rotor and a male rotor adapted to rotate around parallel axes in meshing relation to each other. The leading side flank of the female rotor is constituted by a first leading side flank formed by an arc of a radius R.sub.1 and a second leading side flank formed by an arc of a radius R.sub.2. Also, the trailing side flank of the female rotor is constituted by a first trailing side flank formed by an arc of the tooth ends of the male rotor having a radius R.sub.5 and a second trailing side flank formed by an arc of a radius R.sub.3 which is smaller than the radius R.sub.2 of the second leading side flank. The configuration of the teeth of the male rotor is materially formed by arcs of the leading and trailing side flanks of the female rotor.

    摘要: A scroll-type fluid apparatus including an orbiting scroll member, a stationary scroll member, and a plurality of pockets formed in at least one of the orbiting scroll member and the stationary scroll member to cooperate with the other scroll member for confining liquid therein. When an axially urging force is ecerted on the orbiting scroll member, a liquid pressure commensurate with the axially urging force is produced in the pockets, so that such liquid pressure cancels out a biased axially urging force (moment) exerted on the orbiting scroll member.
