Easy with 90-degree operation! Prevents over-tightening and damage! "I'm worried if it's tightened securely..." We solve this kind of problem.

The "BQL400NB model" is a rapid opening and closing type handle diaphragm valve from BioClean. While the standard handle type requires about 5 rotations for operation (in the case of DN50), the rapid opening and closing handle allows for a very simple operation of just "opening and closing by 90 degrees." The valve's open and closed status can be clearly identified from a distance based on the handle position. Additionally, it has achieved a lighter and more compact design compared to conventional products. We invite you to try the easy operation and stable sealing performance of the 90-degree rotating lever handle. 【We solve these problems!】 ■ Excessive opening and closing torque → Reduction is possible, greatly contributing to labor savings. ■ Want to check the opening and closing status from a distance → The valve's open and closed status can be clearly seen from a distance based on the handle position. ■ Damage caused by over-tightening the valve → Only the minimum necessary operation is required. This prevents damage and extends the lifespan. *For more details, please refer to the PDF materials or feel free to contact us.

We will be exhibiting at the "P-MEC Japan 2025 Pharmaceutical Ingredients and Equipment Exhibition" held at Tokyo Big Sight. During the event, we will showcase various products. We invite all relevant parties to come and visit us. 【Suppliers】 ・LAUDA

Seiko Co., Ltd. will be exhibiting at the "11th Monozukuri World Nagoya" held at Port Messe Nagoya. This exhibition features approximately 630 companies showcasing advanced technologies that contribute to shortening development and manufacturing periods, promoting DX and IT, reducing costs, and enhancing energy efficiency and automation in factories, including IT and DX products, parts, equipment, devices, and measurement products. We plan to display the actual cabinet for equipment management, "SMART BEE," so please be sure to visit us. 【Model Numbers】 ■ Vending Machine Type Tool Management Cabinet Smart Bee X, Smart Bee S, Cute Bee, Smart Bee Pro ■ Locker Shelf Type Tool and Consumables Management Cabinet T Series: T57, T100, T108 TW Series (with electronic scale): TW45, TW68, Hyper S, Hive

We will be exhibiting at "Japan DX Week Spring 2026," which will be held at Tokyo Big Sight from April 8 (Wednesday) to April 10 (Friday). At the Marble booth, we plan to showcase how AI can improve work efficiency and lead to business automation in on-site operations. Additionally, we will provide an opportunity to experience a demonstration utilizing the latest technology, AR. Furthermore, for our manufacturing industry customers, we will present proposals under the theme "Utilizing Drawings to Drive DX," promoting the digitalization of design and quality areas, and introducing packaged products and custom services aimed at enhancing productivity in the manufacturing sector.

Core systems are the foundational support for corporate management, and their importance is increasingly heightened in the DX era, where data becomes a source of competitive advantage. To respond swiftly and flexibly to the rapidly changing business environment, a transformation in the nature of systems is required. We will introduce a method to realize a highly flexible and scalable business system that promotes operational efficiency and data utilization through the combination of kintone and ASTERIA Warp, using examples and demonstrations.

The widespread adoption of generative AI is rapidly evolving from traditional "conversational AI" to "autonomous execution AI (AI agents)." The AI agents that have recently garnered attention are not limited to merely generating responses; they can incorporate an autonomous processing flow of "planning → task decomposition → execution → evaluation," serving as new partners that can substitute and expand users' business operations. In this seminar, we will clearly introduce the following topics, incorporating examples of the AI solution "AIdea Suite AGENT +plus" and the data integration tool "ASTERIA Warp": - Why "AI agents" are becoming essential for corporate competitiveness now - The mechanisms of AI agents and specific use cases - Methods for establishing business efficiency, creating new value, and gaining a competitive edge - Specific steps for implementing AI agents - Data integration and its methods, which are essential for utilizing AI *This is a re-broadcast of the seminar held on October 30, 2025 (Thursday).
