Latest Patents

Hirano's latest patents include the "Inverted Type Liquid Sealed Mount" and the "Inverted Liquid Sealed Mount." The Inverted Type Liquid Sealed Mount features an annular liquid chamber resonance that is controlled without using flow resistance. This design includes a secondary liquid chamber located above a primary liquid chamber, with a main body section of an insulator projecting upwardly in a chevron shape. A control projection on the outside wall of the main body section is configured to produce elastic body resonance, allowing for improved durability by increasing the size of the control projection to endure flow resistance.

The Inverted Liquid Sealed Mount incorporates a secondary liquid chamber above, with an insulator protruding into a primary liquid chamber. A resistor is mounted within an annular recess section and is elastically supported by ribs, allowing it to move due to liquid flow. This design addresses peculiar resonance issues by decreasing the peak of anti-resonance and shifting the frequency, thanks to the movable resistor.
