Title: **Innovative Contributions of Kiwao Seki**

Introduction

Kiwao Seki, an accomplished inventor based in Katsuta, Japan, has made significant strides in the field of liquid analysis technology. With a portfolio of seven patents, Seki has established himself as a key figure in the research and development landscape. His innovative approach has contributed to advancements in liquid chromatographic and electrical conductivity measurement apparatuses.

Latest Patents

Among his latest innovations, Seki has developed a **Liquid Analyzing Apparatus**. This apparatus addresses the potential damage that can occur in a liquid chromatographic analyzer when the flow passage becomes blocked, leading to increased internal pressure. To mitigate the risk of damage, the design allows for external discharge of the liquid through a liquid discharging tube. A spring member is thoughtfully incorporated between the flow cell and the seal to facilitate controlled liquid leak under high pressure. Additionally, a light-proof tube is connected to block light and direct the leaked liquid safely away from the apparatus.

Another noteworthy invention is the **Apparatus for Measuring Electrical Conductivity**. This device measures the electrical conductivity of liquid by utilizing multiple electrodes within a measuring cell, to which an alternating current (a.c.) voltage is applied. This system effectively measures current flow between the electrodes, while the integration of a reference a.c. voltage source allows for adjustments in magnitude and phase. Such adjustments enable the apparatus to cancel out background conductivity, resulting in more accurate measurements.
