Latest Patents

One of his latest inventions is the ultrasonic microscope apparatus, which utilizes cryogenic fluid as an ultrasonic propagating medium. This innovative apparatus features a top loading space that allows for specimen exchange while maintaining an airtight environment. It is equipped with x-, y-, and z-direction adjusting devices that enable precise positioning of the specimen relative to an acoustic lens. Additionally, the apparatus includes a vapor pressure adjusting device to regulate the vapor pressure within a heat-insulated vessel, preventing the cryogenic fluid from boiling.

Another significant patent is the method and apparatus for measuring immunological reactions. This invention employs a coherent laser light flux projected into a transparent quartz cell. The light scattered from particles in an antigen-antibody reaction liquid is detected by a photomultiplier through a collimator. The output electrical signal from the photomultiplier is sampled at various time instances, and these samples are processed using a fast Fourier transformer to derive multiple power spectrum densities of the scattered light's intensity fluctuations. By averaging these densities, the mean power spectrum density is generated, which is then used to measure the amount of antigen in the reaction liquid.
