Title: Tsutomu Ito: Innovator in Air Suspension and Linear Compressor Technologies

Introduction

Tsutomu Ito is a prominent inventor based in Sagamihara, Japan. He has made significant contributions to the fields of automotive technology and compressor systems, holding a total of 11 patents. His innovative designs focus on enhancing the efficiency and reliability of air suspension systems and linear compressors.

Latest Patents

Among his latest patents are an air suspension system and a camera cleaning system. The air suspension system is designed to improve the trackability of stroke control concerning pressure fluctuations applied to a linear compressor. It effectively suppresses stroke increase due to pressure drops, prevents piston collisions, and increases flow rates by reducing dead volume. This system includes various components such as an air suspension for supplying and discharging compressed air, a compressor body with a reciprocating piston, a linear motor, a storage tank for compressed air, a solenoid valve for controlling air flow, and an inverter for position control of the piston.

Additionally, his linear compressor and control system do not require a sensor for detecting the position of a mover. Instead, it computes the mover's position with high accuracy, taking into account the position dependency of an induced voltage constant. The linear compressor features a field element with a permanent magnet, an armature with a winding, and a linear motor that facilitates the relative reciprocation of the field element and armature.
