Latest Patents

One of his latest patents is titled "Sliding member having a novel pore structure on the sliding surface." This invention relates to a sliding member designed with a unique micropore structure that enhances seizure resistance and seal properties. The sliding member is characterized by a hardness of at least HRc 50 and contains micropores that occupy 5% to 40% of the sliding surface area. These micropores, which range from 2,000 to 150,000 per mm², have a diameter of at least 0.5 µm. The design of the top portion of the ridges defining the micropores is slightly rounded, which contributes to improved performance.

Another significant patent is the "Mechanical face seal with minute pores in sliding surface." This invention features a mechanical seal that includes a fixed member securely attached to the outer circumference within a compressor's bearing house. The rotary member, which is mounted on the rotary shaft, has a hardness of Hv 350 and contains minute pores of 30 µm or less in maximum diameter. This design allows for the retention of lubricating oil, effectively sealing the compressor housing to prevent gas and oil leakage.
