Would you like to save energy by conserving water through tank cleaning?

**Features** Rehira Corporation has established five classes based on cleaning power. Rotary cleaning nozzles of class 2 and above commonly adopt a "low-pressure specification" that saves energy and is less prone to wear, as well as a "cleaning head" that is lubricated with cleaning fluid. The series that employs a "free-spinning head" lifts dirt with strong repetitive impacts and washes away tank contaminants, while the series that uses "internal drive control" maintains head speed to provide powerful spray effects by harnessing liquid flow to power the internal turbine head, making it suitable for large tank cleaning. We also offer sprays for cleaning relatively small tanks centered around class 1, which includes fixed cleaning nozzles, and we have various tank cleaning nozzles available, allowing us to recommend cleaning nozzles tailored to the size, shape, and purpose of your tank. **Differences from Other Companies** Our company can conduct tests on a PC using software for "visualization" before performing actual machine tests. Please feel free to contact us for inquiries.

Do you want to use SOLIDWORKS more conveniently but think, "API seems difficult..."? How about trying to create a macro together? The theme is "Automating just one process." This time, we will create a system that automates the simple task of "saving," which you do manually every time in SOLIDWORKS, so that it can be completed with one click. Even if you have never written code before, that's okay. By simply "tracing and creating together" the necessary parts, you will be able to experience the excitement of actual automation in action. Through this webinar, I hope you will realize, "Oh, I can start with something this small in API." ■ Recommended for: - Those who do not fully understand how to utilize SOLIDWORKS API - Those who are not familiar with macros - Those who want to automate their design processes - Those who want to reduce human errors, even just a little.

[Speaker] Associate Professor Naoshi Matsuhisa, Center for Advanced Science and Technology, The University of Tokyo [Key Lecture Content] Various soft and stretchable electronic materials that break the common belief that rubber does not conduct electricity are being developed.

[Lecturer] Yoshiaki Otsuki, Special Counsel, Anderson Mori & Tomotsune Law Office, Foreign Law Joint Enterprise [Key Lecture Content] Rare earth elements are metallic minerals commonly used in electric vehicles (EVs) and smartphones, but it is said that a large portion of their production relies on China. However, in light of the recent intensification of U.S.-China tensions and other international circumstances, concerns have arisen regarding the security of rare earth supply. In this context, the development of rare earth projects within Japan's territorial waters or exclusive economic zone (EEZ) has suddenly come into the spotlight. This lecture will focus on the legal aspects of rare earth development projects within Japan's territory, particularly addressing the application issues of the Mining Act, which was amended in 2022. [Lecture Topics] Chapter 1: Introduction - International Situation Surrounding Rare Earths Chapter 2: Application of the Mining Act Regarding Rare Earth Development in Japan's Territory Chapter 3: Future Outlook Q&A / Business Card Exchange

[Speaker] Mr. Daiki Kaneda, President and CEO of AXIA Marketing Co., Ltd. Mr. Atsushi Nagata, Director [Key Lecture Content] With the rise of manufacturers from emerging countries, the modern era is reaching its limits in competition based solely on specifications and price. The key for Japanese manufacturing industries, such as automotive parts, industrial machinery, semiconductors, chemicals, and steel, to regain growth in the global market lies in a "deep understanding of local technology trends and regulations" and a strategy that "avoids falling too deeply into price competition and transforms into added value." In this lecture, we will explain, using specific examples, how to avoid and leverage the latest local needs and pressures of technology transfer, and how to earn trust. [Lecture Topics] 1. The harsh reality of the global market and the redefinition of "reasons to be chosen." 2. Development strategies to break through the pressures of technology transfer and institutional barriers. 3. Game-changing material selection: the forefront of decarbonization and ESG compliance. 4. Learning from successful cases: a roadmap for market development and a "key" to execution. 5. Q&A session.
