Latest Patents
Koichi Doi holds a patent for a "Balloon controller for a spinning nozzle." This invention features a spinning nozzle that comprises first and second nozzles equipped with jetting holes. These holes allow compressed air to be jetted into tubular yarn passages that extend along an imaginary center line of the spinning nozzle. The nozzles are arranged in series and coaxially with this center line. The second nozzle includes a balloon controller at its outlet end, which has a through hole with a substantially triangular cross-section. This design limits the size of the balloon to that of a circle inscribed in the through hole, ensuring that twists inserted in the yarn in the second nozzle propagate stably to a portion of the yarn in the first nozzle. Koichi Doi has 1 patent to his name.
