Yoshihiro Mitobe has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9556772
    Abstract: A work vehicle includes an engine, a fuel tank that has a fuel supply inlet and stores engine fuel, and a liquid tank that has a liquid supply inlet and stores purification liquid that is used in purification of engine exhaust gas. The liquid tank is protected by the fuel tank so that the liquid tank is not directly exposed to hot air from the engine.
    Type: Grant

  • Patent number: 8181547
    Abstract: A speed change device for a traveling vehicle comprising: a thrust shaft connected to an engine; a speed change mechanism for changing between a high and a low speed provided to the thrust shaft; a counter shaft for transmitting an output from the speed change mechanism for changing between a high and a low speed; a mechanism for switching between advancing and retracting provided to the counter shaft, the mechanism having a forward-rotation idler gear rotatably supported on the thrust shaft; a speed change shaft for transmitting reverse-rotation power from the counter shaft as forward-rotation power via the forward-rotation idler gear; a driven shaft provided as an extension to the thrust shaft; and a main speed-change mechanism having a driving gear group provided to the speed change shaft and a driven gear group provided to the driven shaft.

  • Publication number: 20090059416
    Abstract: According to an aspect of an embodiment, an storage device includes a storage medium having a substrate, a storage medium layer for storing information, a first lubricating layer on a first area of the storage medium layer, and a second lubricating layer on a second area of the storage medium, the second lubricating layer having a viscosity lower than the first lubricating layer. The storage device further comprises a head for writing information into the storage medium layer or reading information from the storage medium layer.

  • Patent number: 6110524
    Abstract: In the method of the present invention, lubricant layers of magnetic discs, which have fixed thickness, can be formed by volatilizing solvent. The method of forming the lubricant layer on the magnetic disc, comprises the steps of: dipping the magnetic disc into a solution in which the lubricant is diluted with the volatile solvent; taking out the magnetic disc from the solution; and volatilizing the volatile solvent from a surface of the magnetic disc, wherein a layer of specific liquid, whose specific gravity is less than that of the solution and which is less volatile and insoluble in the solution, is formed on a surface of the solution.

  • Patent number: 5914168
    Abstract: A magnetic recording medium able to cope with low flying height of the magnetic head in a CSS system and having fine surface roughness, wherein (1) a metal layer having columnar protrusions formed by the filming of Ti or the like or (2) a resin layer or glass resin layer having irregularly distributed through-holes are provided on the substrate of a magnetic recording medium to impart roughness (texture).

  • Patent number: 5047297
    Abstract: A magnetic recording medium, comprising Cr base layer containing up to about 25 atom % of nitrogen, preferably 5 to 15 atom %, and a magnetic film of Co alloy such as Co-Ni or Co-Ni-Cr alloy material deposited thereon, shows a clear improvement over that using a pure Cr base layer without nitrogen content in medium noise level and S/N ratio. In case of about 10 atom % nitrogen content in the base layer, the medium noise level is reduced by half and the S/N ratio is improved by 6 to 9 dB, while the other magnetic characteristics such as coercivity Hc, residual magnetization Br, and squareness ratio Sq are remaining the same.
