Latest Patents

One of Nakajima's latest patents is a drive device that features a drive transmission device. This device includes a drive-side rotatable body, a plurality of magnetic conducting portions, and a driven-side rotatable body. The drive-side rotatable body is equipped with multiple magnetic poles arranged in a rotational direction. The magnetic conducting portions can be magnetized by the magnetic poles, allowing the driven-side rotatable body to rotate in response to the drive-side body. This invention operates as a magnetic speed changer, effectively altering the speed of rotation between the two bodies by adjusting the number of magnetic poles and conducting portions.

Another significant patent is a valve apparatus that consists of a housing with several through holes for fluid flow. This apparatus includes a first valve member that opens and closes a first through hole and a second valve member for at least one second through hole. The design incorporates a fixed core that remains stationary relative to the housing, while a coil generates a magnetic field. The first and second movable cores move in conjunction with their respective valve members, creating a magnetic attractive force that facilitates the operation of the valve.
