Latest Patents

One of Kimura's latest patents is a disk driving device designed to prevent the pivot post from dropping from the base plate. This device includes a disk that rotates about a rotation shaft, a motor that causes the disk to rotate, and an arm that swings about a swinging shaft. The head, located at the tip of the arm, is responsible for reading or writing information. The housing of the device accommodates all these components and features a cast base plate with a bottom wall and an open top, along with a cover. A separate pivot post protrudes from the bottom wall, and a tubular portion accommodates the pivot post, with the arm attached via a bearing. A screw inserted through the cover secures the pivot post's top end. The pivot post includes an annular portion, ensuring stability and functionality.

Another notable patent is related to a spindle motor with a specific bearing part arrangement, which is integral to the disk driving device. This spindle motor consists of a shaft, a base part, a stator core, a rotor, and a bearing part. The shaft extends vertically and features a screw hole that allows for secure attachment. The bearing part includes upper and lower annular members, which are spaced apart in the axial direction, and a sleeve that covers the shaft's outer surface. This innovative design enhances the performance and reliability of the motor.
