Title: Fumiaki Itojima: Innovator in Nuclear Magnetic Resonance Technology

Introduction

Fumiaki Itojima is a notable inventor based in Amagasaki, Japan. He has made significant contributions to the field of nuclear magnetic resonance technology, holding two patents that showcase his innovative spirit and technical expertise.

Latest Patents

One of his latest patents is a nuclear magnetic resonance device. This apparatus is designed to elucidate atomic configuration and molecular structure of substances based on decay signals of induced electromotive force. It operates by utilizing resonance precession of nuclear magnetic moments, which are induced by electromagnetic pulses in the RF region when exposed to a strong magnetic field. The device also features a vibration isolation mechanism that suppresses vibrations. This mechanism includes an air spring connected to a pressurized air source via an electro-pneumatic converter, allowing for active vibration isolation. The design ensures that the electro-pneumatic converter remains unaffected by the magnetic field generated by the nuclear magnetic resonance device.

Another significant patent is the active vibration isolator. This system employs a controller that receives signals from two sensors. The first sensor detects the vibratory state of the object to be isolated, while the second sensor monitors the vibratory state of an intermediate mass element. The controller outputs a signal to a power input portion of a piezoelectric element, causing voltage variations that enable the intermediate mass element to vibrate in a manner that cancels out the vibrations of the object.
