Latest Patents
One of his latest inventions is a vibration isolating apparatus designed to mitigate low-frequency vibrations. This apparatus features a vibrating body situated within a pressure-receiving liquid chamber, which is connected to a mounting member. An elongated limiting passage penetrates the vibrating body, allowing for liquid-column resonance that effectively absorbs low-frequency vibrations. Additionally, the apparatus is capable of absorbing high-frequency vibrations by decreasing the dynamic spring constant when vibrations occur near the gap.
Another significant invention is a liquid-containing type vibration isolating apparatus. This device includes a first restricting passage that connects a pressure-receiving liquid chamber to a first sub-liquid chamber, along with a longitudinal second restricting passage. This design allows the apparatus to reliably absorb vibrations while occupying minimal space, making it a practical solution for various applications.
