He has made significant contributions to the field of engineering, particularly in the development of improved coupling mechanisms for conduits. His innovative designs have the potential to enhance the efficiency and reliability of various applications.

Latest Patents

One of Takashi Tajima's key patents is for a coupling for corrugated conduit. This invention features a main tubular body with a sleeve that defines a conduit receiving bore. The bore terminates at its inner end in an annular shoulder that projects radially inwardly of the tubular body. A nipple clamps the end portion of the conduit and is inserted into the conduit receiving bore, where it is pressed forwardly by rotating a nut threaded on the sleeve. This design forces the end of the conduit into pressing contact with the shoulder. The nipple is externally shaped to have a polygonal configuration, allowing it to be slidably but unrotatably inserted into the correspondingly shaped conduit receiving bore. This prevents the conduit from twisting during the securing operation of rotating the nut about the sleeve. Takashi holds 1 patent for this innovative coupling design.
