Notice of Participation in "SURTECH 2026 Surface Technology Elements Exhibition" from January 28 (Wednesday) to January 30 (Friday), 2026.

To streamline routine inspections, reduce sludge generation, stabilize treatment water quality, and prevent accidents!

By utilizing an IoT remote monitoring system for the filtration equipment and wastewater treatment facilities of Sanjin Manufacturing, we can monitor and confirm abnormalities occurring in the equipment on-site. Additionally, by saving and graphing the measurement data from pH meters and ORP meters, we can analyze the operational status. 【Features】 ■ By managing and monitoring the quality fluctuations of treated water in the factory, which can vary significantly depending on production conditions, using IoT and sensors, we can reduce the labor involved in daily inspections on-site. ■ By quantifying daily operational conditions and water quality, chemical control becomes easier, leading to a reduction in sludge generation and stabilization of treated water quality. ■ Data monitoring allows for quick and appropriate responses in the event of trouble, preventing accidents. 【Examples of Achievements】 In addition to enabling the confirmation of abnormalities in wastewater treatment equipment from the production line side, we have built an IoT system utilizing the internal network to record the pH value of the neutralization tank. *We will build a system tailored to your needs. Please feel free to contact us for more details.

[Speaker] Mr. Kei Nishishita, Senior Researcher, Advanced Technology Lab, Japan Research Institute, Ltd. [Key Lecture Content] Neurotech is a collective term for technologies that utilize insights from neuroscience, and in recent years, it has also been referred to as brain tech, with accelerated research and development and commercialization efforts both domestically and internationally. This seminar will systematically organize the foundational technologies and latest trends in the neurotech field, while also highlighting advanced initiatives underway in Japan and abroad, explaining their characteristics and implications. Additionally, considering the current state of neurotech being implemented in society, we will also address changes in the surrounding environment, such as ethics, legal frameworks, and social acceptance. Furthermore, as the integration with the AI field progresses, we will explore what developments can be anticipated in the future and what opportunities and risks may arise in business development from a multifaceted perspective. [Lecture Items] 1. Overview and Current Status of Neurotech 2. Advanced Examples of Neurotech 3. Social Trends Surrounding Neurotech 4. Future Outlook and Strategies for Business Applications 5. Q&A

[Speaker] Takuki Nakani, Representative and Analyst, Nakanishi Automotive Industry Research Co., Ltd. Author of "Toyota vs. Chinese EVs" [Key Lecture Content] A powerful group of the strongest EV manufacturers in the Chinese market and their robust supporting ecosystem are emerging prominently. This is organically linked to China's digital national strategy. As the competitive landscape of the global automotive industry changes with the evolution of SDVs and AI, can Japanese manufacturers chart a path to victory? With an eye on the fragmentation of industrial hegemony, we will examine the future structure of the automotive industry. [Lecture Items] 1. The structure of the battle over intelligence 2. Competitiveness of the strongest Chinese EV manufacturers 3. Japan's OEM strategy against China 4. Japan's path to victory – SDV value chain strategy 5. Evolution of manufacturing accompanying the SDV shift 6. Q&A / Business card exchange
