Title: Yunosuke Iizuka: Innovator in Bore Hole Scanning Technology
Introduction
Yunosuke Iizuka is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of bore hole scanning technology. With a total of 2 patents, his work focuses on enhancing the efficiency and accuracy of bore hole inspections.
Latest Patents
Iizuka's latest patents include a bore hole scanner with a position detecting device and light polarizers. This innovative bore hole scanner features a light projecting device that directs a beam of light toward the bore hole wall surface. A conical mirror is arranged coaxially with respect to a sonde, condensing light reflected from the bore hole wall. An image forming device is positioned in front of the conical mirror, while a photoelectric transducing device converts the light signal into an electric signal. Optical fibers are utilized to introduce the image formed on concentric circles to the photoelectric transducing device. A data processing device scans and extracts signals from the photoelectric transducing device, generating and processing image data indicative of the bore hole wall surface. Additionally, a sonde position detecting device is employed to detect the orientation and position of the sonde, eliminating the need for rotating components.
Another patent involves a borehole scanner and sonde position locator for spectral analysis of the wall. In this invention, an optical head is rotated while the sonde is moved up or down within a bore hole. A beam of light is projected toward the wall of the bore hole via a series of optical components. Reflected light is extracted and processed to perform color tone logging and other observations. The orientation and inclination of the sonde are sensed using specialized instruments, allowing for precise tracking of the sonde's position.
