Latest Patents
One of his latest patents is for a hermetic type compressor. This high-performance compressor reduces the influence of cylinder bore deformation during assembly, improving the sealing tightness between the piston and the cylinder block. The design features a bore hole in the cylinder block with a hollow portion, where the depth of the hollow portion exceeds the thickness of the compression space when the pressure reaches the discharge level.
Another significant patent is for a spindle motor and its manufacturing process. This spindle motor includes a bearing housing and a thrust bearing fitted at the lower end. An inclined part is formed on the outer edge of the thrust bearing, which is fitted into a coupling bore in the bearing housing. The design ensures that the bearing housing uniformly presses in the axial direction, allowing for a high bonding strength between the housing and the thrust bearing without compromising the sealing ability of the motor.
