Title: Katsushi Nakano: Innovator in Groundwater Sampling Technology

Introduction

Katsushi Nakano is a notable inventor based in Toki, Japan. He has made significant contributions to the field of groundwater sampling technology, holding 2 patents that enhance the efficiency and reliability of water sampling processes.

Latest Patents

One of his latest patents is the "Packer Type Groundwater Sampling System and Water Sampling Method." This invention provides a system and method for sampling groundwater under in-situ conditions in a reliable, efficient, and economical manner, without disturbing the environment of formation water present in underground layers. The system includes both a continuous water sampling process and a batch-style water sampling process, ensuring that the same environmental conditions as the groundwater are maintained during sampling. After drilling, water is removed using the continuous sampling process, followed by repeated sampling of formation water through the batch-style process. The downhole system is designed to move up and down within a casing pipe, allowing for insertion into or removal from a packer system in the borehole.

Another significant patent is the "Hydraulic Test System Mounted with Borehole Television Set." This invention allows for the selection of a proper position and reliable measurement intervals corresponding to that position. It provides information to prevent equipment retention in the borehole and enables observation of conditions in both front and lateral directions simultaneously, using a single borehole television (BTV) set. The measurement pipe features a waterproofing cylinder with a transparent window, allowing for simultaneous observation in both directions, and is equipped with illumination units and a borehole television set that forms virtual images of objects in both front and lateral directions.
