Title: Tetsuya Maruyama: Innovator in Fluid Dynamic Bearing Technology
Introduction
Tetsuya Maruyama is a prominent inventor based in Kyoto, Japan. He has made significant contributions to the field of fluid dynamic bearing technology, holding a total of 5 patents. His innovative designs have advanced the performance and reliability of various mechanical systems.
Latest Patents
Maruyama's latest patents include a fluid dynamic bearing apparatus, a spindle motor, and a disk drive apparatus. In his fluid dynamic bearing apparatus, an oil buffer is defined between a thrust gap and a pumping gap. The oil buffer has an axial dimension greater than that of the thrust gap and/or has a radial dimension greater than that of the pumping gap. This design allows an air bubble generated in the thrust gap due to cavitation to be dissolved in the lubricating oil provided within the oil buffer. This prevents leakage of the lubricating oil due to the air bubble residing in the fluid dynamic bearing apparatus. Furthermore, his fluid dynamic bearing apparatus features a specific minute gap structure with a spindle motor and disk drive apparatus. It includes multiple minute gaps and dynamic pressure generating grooves that facilitate the flow of lubricating oil, ensuring efficient operation and minimizing air bubble retention.
