Fumiaki Shimizu

Title: Fumiaki Shimizu: Innovator in Air Purification and Packaging Technologies

Introduction

Fumiaki Shimizu is a prominent inventor based in Nara, Japan. With two patents to his name, he has made significant contributions to the fields of air conditioning and hermetic packaging. His innovative ideas reflect a commitment to enhancing indoor environments and improving packaging technologies.

Latest Patents

Shimizu's latest patents include an air refining device and an ion generator used within an air conditioning apparatus. This innovative system incorporates an ion generating device that produces both positive and negative ions by applying an alternating-current voltage between electrodes. These ions coexist in the air and play a crucial role in reacting chemically with airborne bacteria, generating radical hydroxyl and hydrogen peroxide. This process effectively extracts hydrogen atoms from the cells of bacteria, thereby eliminating them and ensuring a sterilized environment. The air conditioning apparatus combines this sterilizing effect with temperature conditioning, dehumidifying, humidifying, and air-purifying functions, fostering a comfortable and healthful indoor atmosphere.

Another notable patent by Shimizu is the hermetic packaging apparatus. This technology features a nozzle designed to reduce pressure in a thermoplastic packaging bag that contains specific contents. The nozzle utilizes pressure control from an air pump to extract water from the contents, directing it to a strainer tank. Following this, the nozzle moves backward, and the opening of the packaging bag is heated by a heating element. An airtight pressure connecting bar applies downward pressure to heat-seal the opening portion securely to the sealing base, ensuring the integrity of the packaged contents.
