Title: Innovations of Yoshinori Ogawa
Introduction
Yoshinori Ogawa is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of technology, particularly in the development of components for magnetic disk drives. With a total of 10 patents to his name, Ogawa's work has had a substantial impact on the industry.
Latest Patents
One of his latest patents is for a yoke for a voice coil motor in a recording disk drive. This invention involves a first yoke member that is received on a first reference plane defined on a support body. A second yoke member is coupled to the first yoke member, creating a space for the accommodation of a voice coil. The second yoke member is opposed to a second reference plane, which is different from the first reference plane. A screw member is engaged with the second yoke member, allowing for movement in a direction that intersects the second reference plane. This design ensures that even if a gap exists between the second yoke member and the second reference plane due to dimensional errors, the second yoke member is reliably supported on the support body.
Another notable patent is for a magnetic disk drive capable of reducing noise at startup. This invention utilizes conjoining, damped washers to support shafts in the disk drive. The magnetic disk drive includes a spindle shaft fixed to a base, a coil mounted on the spindle shaft, and a spindle hub that is rotatably mounted on the spindle shaft. The design incorporates a magnetic disk fixed to the spindle hub, a permanent magnet, and a magnetic head for reading and writing information. The drive also features a cover with a hole corresponding to the spindle shaft, along with metal washers that secure the assembly.
