  • Publication number: 20210060675
    Abstract: An oil hole reamer includes an oil passage extending inside a tool main body along an axis of the tool main body, and an oil hole extending radially outward from the oil passage to an outer circumference of the tool main body. An oil outlet of the oil hole is formed to be open toward a position corresponding to a corner at which a tip cutting edge intersects an outer-circumference cutting edge and to cause at least part of the oil outlet to be open to the outer-circumference flank face.

  • Patent number: 7488420
    Abstract: A chromatographic separator characterized in that two pumps are employed for controlling chromatographic separation that combines a first process for supplying at least one of feed solution and eluent into a circulation system and extracting the same quantity as that of liquid supplied into the circulation system from one position of a packed column where some component is enriched in the circulation system, and a second process for circulating liquid in the system without supplying the feed solution and eluent and extracting the separated component at all. Easy-to-control chromatographic separator, in which a total number of pumps to be used is decreased and high separation performance is attained through a simple structure, can thereby be provided.
