Latest Patents
One of Kitagawa's latest patents is a cable protection and guide device. This device allows for easy maintenance of cables without the need to completely remove the cable accommodating space extension arm from the side plate. The design prevents inadvertent disengagement of the arm, ensuring it strongly engages the side plates. The device consists of several pairs of right and left side plates connected to each other, with cable accommodating space extension arms bridging over the flexional inner circumferential sides of at least one pair of side plates. The hinge ends of the arms feature D-shaped pin hinge shafts that are detachably interengaged with a groove in one of the side plates, allowing the arm to pivot. Additionally, hinge end side locking pawl pieces of the arms are interlocked to the side plates.
Another notable patent involves a roller chain that incorporates rolling bodies. In this design, a plurality of rolling bodies is positioned between a roller and a bushing, between a bushing and a pin, or between a roller and a pin. The rolling bodies include at least one carbon-impregnated ceramic rolling body or at least one carbon-coated steel rolling body. The innovative aspect of this design is the alternating configuration of carbon-impregnated or carbon-coated rolling bodies with steel rolling bodies.
