[Sample Distribution] Easy installation with sound insulation performance equivalent to LL-45 and insulation performance comparable to high-performance glass wool insulation material 48K! 40mm thick low-floor substrate material.

Product Name: Chardan SPF400 【Features】 ✔ Low height of 40mm! ✔ Integrated soundproofing and insulation unit ✔ Reduced construction time to less than 1/3 compared to dry double flooring! (In-house research) ✔ Achieved LL-45 with SPC flooring! A multi-type that does not limit the choice of top materials This is a floor soundproofing material laid under flooring with a thickness of 40mm. It has been certified for performance with SPC flooring, which is said to be thin and hard, making it difficult to ensure soundproofing performance. With Chardan SPF400, SPC flooring can be used not only in commercial facilities but also in multi-family housing and welfare facilities where soundproofing and insulation functionality is required. Since it is a form that fills the underfloor space with special sound-absorbing material, it provides both soundproofing performance and insulation effect in one package. SPF400 Thermal Conductivity: 0.040 [W/(m·K)] SPF400HS Thermal Conductivity: 0.033 [W/(m·K)] * SPF400HS is a high insulation version of SPF400. Its composition and basic performance (thickness/soundproofing/constructability/safety) are equivalent to SPF400. Using dedicated edge treatment materials and fastening components, we achieve innovative construction that reduces construction time and noise.

【Sample available!】Simply stick it to the underside of a metal roof to reduce rain noise. With about 30% coverage relative to the roof width, the effect is outstanding!

Product Name: Zetoro NV-αII 【Features】 ✓ Just apply 30% of the width of the roofing material! ✓ Reduces indoor and outdoor rain noise by 10dB ✓ Industry’s thinnest! Despite being only 0.55mm thick, it effectively addresses rain noise ✓ Can be applied without hardening even in winter conditions ✓ Easily cut with scissors or a cutter Metal roofs are excellent in durability, design, and workability, but their soundproofing performance is insufficient, so vibration-damping tape is used to solve rain noise issues. The vibration-damping tape applied to the metal roof converts the vibrational energy from falling raindrops into thermal energy, thereby suppressing the generation of rain noise. The roofs of residences with applied vibration-damping tape reduce noise not only indoors but also outdoors. Zetoro NV-αII, which reduces rain noise by applying just 30% of the roofing material's width, can be used in cover methods during new construction or renovation.

[Lecturers] Daisuke Tateno, Partner, Arthur D. Little Japan K.K. Akihiro Nagayama, Principal [Key Lecture Content] Drones, AI, software, satellites, and electronic warfare are fundamentally changing the way wars are fought, and the defense industry is currently transitioning from a heavy and traditional model to one centered around AI, software, data, and unmanned systems. In the United States, emerging companies like Palantir and Anduril, which are software-driven, are challenging existing defense firms. In Japan, structural changes are beginning with the Defense Capability Development Plan, the Defense Industry Base Strengthening Act, and the entry of startups. This seminar will discuss the changes in the global security environment and industrial structure, the strategies of advanced players both domestically and internationally, and the areas where Japanese companies can succeed, including dual-use, collaboration with software companies, M&A and alliances, and talent strategies. We will consider how to view change not as a threat but as a growth opportunity, and how to construct a new Japanese defense industry from a management perspective.

[Speaker] Kazuki Miyamoto, Representative/Analyst, VentureClef, USA [Key Lecture Content] The frontier model in the United States is evolving at an unexpected speed. AI agents based on the frontier model have completely transformed business forms in companies. Chinese companies are developing large-scale open source projects, and their performance is approaching that of the U.S. model. Meanwhile, U.S. companies have begun developing open source, leading to a direct confrontation between the U.S. and China. The seminar will examine the frontier models of both countries and explain the latest technologies and important trends. It will organize points on how Japanese companies should perceive the U.S.-China AI development competition from technological and business perspectives. It will also consider strategies for companies to succeed in the AI era, including the differentiation between the U.S. and Chinese models, as well as the advantages and challenges of open source versus closed source.
