Title: Hitoshi Harada: Innovator in Filter Technology and Heat Insulation

Introduction

Hitoshi Harada is a notable inventor based in Kariya, Japan. He has made significant contributions to the fields of filter technology and heat insulation, holding a total of 2 patents. His innovative designs reflect a deep understanding of material science and engineering principles.

Latest Patents

One of Harada's latest patents is the Zig Zag Filter Element. This filter element features a plurality of wavy portions arranged to form a generally ring-like structure. To minimize pressure drop during fluid flow, the design incorporates specially shaped radial gaps. The first radial gap, connecting to the inner space of the structure, increases in width from the outer to the inner end. Conversely, the second radial gap, which connects to the outer atmosphere, decreases in width from the outer to the inner end. Both axial ends of the wavy portions are covered with an adhesive sheet that has an adhesive layer cladded.

Another significant patent is for Heat Radiating Insulation for Coil. This invention involves a thermosetting synthetic resin composition, primarily made of epoxy resin, which is melted at temperatures between 70°C to 130°C. After adding a filler, such as aluminum in amounts ranging from 30 wt % to 100 wt %, the mixture is kneaded and rapidly cooled. The resulting powder is then coated onto a coil and cured to create an effective heat radiating insulator.
