Exhibition Information ： AUTOMOTIVE ENGINEERING EXPOSITION 2026 YOKOHAMA

Air leak tester specifically for airtightness inspection of large battery cases and similar items.

Fukuda Corporation will exhibit at the "2025 YOKOHAMA International Automobile Technology Exhibition"! Please be sure to check out this product at Fukuda's booth! This product is an air leak tester for battery cases of electric vehicles (EVs). The battery case features a structure that is "large with a significant internal volume, and deformation is expected due to internal pressurization." As a result, air leak testing generates noise caused by "the large size and volume" and "expansion or deformation due to internal pressurization." This product is characterized by the use of newly developed smoothing and linear fitting correction functions to reduce this noise during measurement. Additionally, to achieve precise low-pressure control and flow expansion for large volumes, we provide a bypass box (CBU-600) equipped with a pressure regulator that allows for accurate pressure control and a pressure valve with a large effective diameter to supply high flow rates.

Separate type air leak tester "LPU-300 series" "LPU-100/024 series"

The air pressure unit and measurement sensors can be bundled together, while control and display options are available separately. The "LPU-300 series" is the smallest measurement unit in Fukuda's history, making it ideal for direct attachment to as small a workpiece as possible. It can achieve higher measurement sensitivity compared to conventional all-in-one leak testers (depending on measurement conditions). The "LPU-100 / LPU-024 series" is used as a separate air leak tester in combination with display units (MI-170 / MIZ-0175 / DG-960). The separate display design makes it easier to position the measurement unit close to the workpiece. 【Features】 ■ Compact design that is easy to integrate into measurement devices ■ LPU-300 with control circuit sold separately, and LPU-100/024 where control is left to the customer ■ Rational and low-cost, choosing only the necessary functions ■ Even at a low cost, the differential pressure sensor is equivalent to general-purpose models ■ LPU-300 has a sensor volume of less than 1 mL, excelling in high-sensitivity measurements *For more details, please refer to the PDF document or feel free to contact us.

A high-sensitivity leak testing machine that uses hydrogen gas. It features improved convenience and operability, and is a compact detector equipped only with the necessary functions.

It is used to measure the overall leakage from the entire inspected item (work). - The work is covered with a chamber, tracer gas is filled inside the work, the leaked gas accumulates in the chamber, the leaked gas is stirred and forced to circulate, and the gas concentration is measured using a hydrogen detector [Atmospheric Pressure Chamber Method]. - After creating a vacuum in the chamber, atmospheric air is introduced into the chamber, and gas is directed to the hydrogen detector, allowing for highly sensitive measurements [Vacuum Chamber Method]. There are two methods. The design is compact and lightweight, making it easy to integrate into equipment. Additionally, the concentration resolution capability is ultra-sensitive up to 0.1 ppm (depending on the set conditions and environmental conditions). *For more details, please contact us.

[Instructor] Hiroto Hayashi, Attorney at Law, New York State, Mori Hamada & Matsumoto Law Firm, Foreign Law Joint Enterprise [Key Lecture Content] Recently, batteries are expected to serve as a balancing power source for the realization of renewable energy as a primary power source. Due to changes in the business environment brought about by market development and government support measures, opportunities in the battery business are expanding. For grid-connected batteries, there are multiple options for long-term decarbonization power source auctions, tolling models, and merchant models, and the points of project development vary depending on the offtake method. Additionally, with the spread of the FIP system, the installation of batteries alongside renewable energy generation facilities is also progressing. In this lecture, we will explain the systems related to batteries, as well as key points for contract creation and negotiation, and financing necessary to steadily advance projects. We will also outline the challenges and prospects for project development and project finance formation according to each offtake scheme.

[Lecturer] Hideo Yamada, Ph.D. Honorary Professor, Waseda University Visiting Professor, Business Breakthrough University Graduate School [Key Lecture Content] Companies face various trade-offs (dilemmas) such as quality vs. cost, inventory levels vs. service levels, and standardization vs. differentiation. Traditionally, companies have responded to trade-offs by (1) finding a balance or (2) prioritizing one over the other. However, this does not lead to fundamental solutions. In this lecture, I will propose a third method that is neither balancing nor prioritizing. Using case studies from over 50 Japanese companies, I will explain it in an easy-to-understand manner. If we can turn long-standing trade-offs into trade-ons (coexistence), business opportunities will arise. [Lecture Topics] 1. What is a trade-off? 2. Trade-offs between customers and companies 3. Trade-offs within companies 4. Trade-offs within customers 5. How to turn trade-offs into trade-ons 6. Steps for exploration 7. Q&A / Business card exchange

[Lecturers] Corporate Partner, Nishimura & Asahi Law Office Osaka, Mr. Satoshi Niki Associate, Nishimura & Asahi Law Office - Foreign Law Joint Enterprise, Mr. Shu Numazawa [Key Lecture Content] In recent years, the diversification of defense cooperation and advancements in dual-use technology have significantly changed the management and international sharing of advanced technologies. This lecture will clarify the basic structure of Article 3 of the Japan-U.S. Technology Agreement and the significance of "similar treatment," while explaining the institutional transformation brought about by the introduction of the non-public patent application system under the Economic Security Promotion Act. Furthermore, considering the relationship between this system and the Japan-U.S. Technology Agreement, we will examine how to reposition the patent applications and secrecy management of defense-related technologies within the context of expanding international joint research and multilateral defense cooperation. [Lecture Items] 1. Diversification of defense cooperation and advancements in dual-use technology 2. Basic structure of Article 3 of the Japan-U.S. Technology Agreement 3. Practical application of "similar treatment" 4. Introduction of the non-public patent system (Economic Security Promotion Act) 5. Relationship between the non-public patent system and Article 3 of the Japan-U.S. Technology Agreement 6. Expansion of international joint research and reevaluation of Article 3 7.
