Notice of Participation in the New Value Creation Exhibition 2018

Coloring stainless steel products! Unique technology development.

The "stainless steel coloring treatment" is a technology that creates interference colors (light and a transparent thin film) by changing the thickness of the oxide film on the surface of stainless steel. On the surface of stainless steel, there is an oxide film that causes the colors to change when viewed due to the refraction of light, similar to a CD. With the establishment of this new coloring technology, corrosion resistance has also doubled, leading to improvements in color tone, decorative quality, and distinguishability of products in various fields. 【Features】 ■ A groundbreaking technology that colors the stainless steel itself ■ A film in the nanometer range that does not affect dimensional tolerances ■ The performance of stainless steel remains unchanged while enhancing color tone, decorative quality, and distinguishability ■ It is also possible to perform electrolytic treatment to double the decorative quality ■ Corrosion resistance can be doubled *For more details, please refer to the PDF document or feel free to contact us.

Nitto Kohki will exhibit at the "30th Mechanical Components Technology Exhibition [Tokyo]" held at Makuhari Messe Hall 5 from July 9 (Wednesday) to July 11 (Friday). [Booth Number: Hall 5 31-32] At this exhibition, we will showcase a variety of products, including the electric suction hand "e-VEE" with a built-in pump that does not require compressed air, a cordless belt sander, the electric driver "Delvo" that can be mounted on robots, and the "Flow Monitor" that allows for easy visualization of the flow of cooling water in molds and other applications.

Nitto Kohki will hold the "2025 Attack Fair in Meiko" for two days from July 23 (Wednesday) to July 24 (Thursday), 2025, at the "Kowa Seminar Plaza 2F Training Room NO.12 (inside Kowa Sports Land)." The Attack Fair is an exhibition where you can actually "see, touch, and operate" Nitto Kohki's products. Additionally, there will be wonderful souvenirs for attendees and many fun activities planned. We look forward to welcoming everyone!

[Speaker] EY Strategy and Consulting Co., Ltd. Transaction and Corporate Finance M&A Advisory Director Naoki Saito [Key Lecture Content] In recent years, the grid-scale battery business has garnered significant attention from practitioners, particularly in the renewable energy sector. However, it is also true that there are several challenges that remain to be addressed for further investment expansion. In this lecture, we will explain the finance environment, various markets utilized for revenue generation, and the diversifying business schemes that could influence the success or failure of investment expansion. We will also introduce the current challenges related to each theme, the efforts of market participants towards their resolution or improvement, and future outlooks. [Lecture Items] 1. Overview of the business surrounding grid-scale batteries (historical trends, etc.) 2. Diversifying business schemes 3. Current challenges hindering further investment expansion (finance methods, etc.) 4. Various initiatives towards problem-solving 5. Q&A / Business card exchange

[Speaker] Hiroaki Izuma, Advisor, Business Creation Division, Tohoku Electric Power Co., Inc. Director, Osaka University Foresight Co., Ltd. [Key Lecture Content] Renewable energy (solar power, wind power) is unstable, so Short-term Energy Storage (SDES) is necessary. The main SDES is lithium-ion batteries, which can store energy for several hours, but as the ratio of renewable energy is expected to reach about 50% in the future, Long-term Energy Storage (LDES) will be required. LDES can store energy from 10 hours to several months. The technological classifications of LDES include electrochemical, mechanical, thermal, and chemical methods. In this lecture, we will explain the characteristics of each LDES method, promising overseas startups, and the progress of social implementation, providing insights into new business opportunities. [Lecture Items] 1. Background for the need for LDES 2. Characteristics of the four technological methods 3. Promising overseas LDES startups and social implementation (1) Electrochemical method (2) Mechanical method (3) Thermal method (4) Chemical method 4. Comparison between overseas and Japan 5.
