Title: Innovations by Takeshi Izumitani
Introduction
Takeshi Izumitani is a notable inventor based in Tokyo, Japan. He has made significant contributions to the field of level measurement technology. With a total of 3 patents to his name, Izumitani's work showcases his expertise and innovative spirit.
Latest Patents
Izumitani's latest patents include a level position measuring method, a level marking method, and a level marking apparatus. The level marking apparatus is designed to directly measure height using an elastic synthetic resin tube. One end of the tube is secured to a pressure sensor that produces an output voltage and is air-tight. The other end connects to a reference instrument, which is larger in diameter and shorter in length than the tube. The tube is filled with a low viscosity macromolecule liquid. The pressure sensor is linked to a microcomputer programmed to calculate an average value of the fluctuation waveform within a specific cycle of output voltage. This microcomputer also determines and stores a reference level based on the pressure difference between the reference instrument and the pressure sensor at different heights. Additionally, a marking device is connected to the pressure sensor and is activated by an ON signal when the marking device reaches the same height as the reference level. The marking device and pressure sensor are mounted on a lift that moves along a staff plate, automatically indicating a level mark when the reference level is achieved.
