Notice of participation in "VIETWATER 2025" from Wednesday, October 22, 2025, to Friday, October 24, 2025. {Case studies are also being introduced!!}

Exhibits high airtightness and valve seat sealing performance! Excellent in corrosion resistance, chemical resistance, and cleanability.

A diaphragm valve is a type of valve that has a structure for opening and closing the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Wear-type diaphragm valve: Type 400" is the basic form of a diaphragm valve that has a weir in the flow path. The fluid passage section is streamlined and has no pocket areas, which minimizes liquid accumulation and provides self-cleaning properties. Due to the valve's structure, it exhibits high airtightness and seat sealing performance. There is a wide variety of materials available for the body and diaphragm, allowing it to accommodate a broad range of fluids. ▼Applicable fields: Chemicals, environmental and water treatment, steel, shipping, pharmaceuticals, food, semiconductors, power generation, etc. *For more details, please refer to the catalog (P6–P14) or feel free to contact us. (The English and Chinese versions of the catalog can be downloaded from the catalog page of the special website below.)

The flow path is close to straight, with a structure that has low pressure loss and minimal liquid accumulation! It is suitable for fluids containing sludge, suspended solids, and more!

A diaphragm valve is a type of valve that has a structure that opens and closes the flow path using a flexible diaphragm (membrane) made of materials such as rubber. The "Straight Type Diaphragm Valve: 500 Series" features a flow path that is nearly linear (straight), resulting in a structure with minimal pressure loss and liquid accumulation. It is suitable for fluids containing viscous fluids, fibrous fluids, slurries, sludge, and suspended solids. ▼ Application Fields: Water treatment plants, final treatment facilities, etc. *For more details, please refer to the PDF materials or feel free to contact us.

At the beginning of the seminar, the National Institute of Advanced Industrial Science and Technology will discuss the research and development related to ceramics 3D additive manufacturing that they have been working on, focusing on the 3D additive manufacturing process, powder preparation process for molding, debinding and sintering processes, as well as examples of production using ceramics 3D additive manufacturing, particularly with alumina and reaction-sintered silicon carbide. Following that, instructors from Shin-Toh V-Ceramics and As One, who are at the forefront of this field in Japan, will provide an easy-to-understand explanation for beginners about the development trends of various ceramics 3D printers from world-class companies like 3DCeram Sinto and Lithoz, as well as the latest additive manufacturing technologies that enable the creation of innovative parts, rapid part development, prototyping, and manufacturing, significant reductions in the number of parts, lightweight and compact designs, and reductions in manufacturing processes and workforce through complex shapes and integral molding, hollow and porous structures, and lattice structures that are impossible with conventional processing methods. Finally, Canon will introduce the latest trends in their newly developed high-performance ceramics materials that excel in selective laser melting (SLM) for 3D printers, which significantly reduce "shrinkage" during sintering, along with the characteristics of parts that can be produced using this method, additive manufacturing technology, target fields, and contract manufacturing services.

Nagoya Chemical Industry Co., Ltd. will be exhibiting polyimide resins at the booth of Matsuo Sangyo Co., Ltd. during the 'Chemical Material Japan 2025' event held at Tokyo Big Sight. We also plan to showcase our developed products, including soluble polyimide, transparent polyimide, and porous polyimide, so we look forward to seeing you there.

In promoting DX and business reform projects, are your initiatives becoming "system construction first"? While you may have envisioned an ideal, it may not lead to "practical reforms" rooted in the field. For those facing such challenges, this seminar will provide hints for solutions. In this seminar, we will clearly explain the specific approach from "visualizing business processes" to "IT strategy (systemization strategy)" in business reform projects, incorporating case studies and practical steps. We will also introduce the essence of our "business process-focused, supportive consulting." Additionally, details on writing business flows, creating RFPs, and formulating systemization roadmaps will be covered in a separate seminar.

～AI Chatbot Breaks Through the Barriers of Business Knowledge! A Method to Achieve Both Talent Development and Business Efficiency Simultaneously～ The burden of searching through vast amounts of documentation in quality assurance operations has been dramatically improved by the generative AI chatbot "WisTalk"! In this seminar, Panasonic Industry Co., Ltd. will present a case study on how they utilized "WisTalk" to reduce the search workload for over 4,000 pages of quality assurance documents while balancing business quality and talent development. 【What You Will Learn in This Seminar】 ● How to inherit the knowledge of experienced personnel using AI ● The effects of reducing business burdens and improving performance through the efficiency of document search operations ● Key points for implementing an AI chatbot for knowledge search 【Recommended For】 ● Those who feel challenges in searching for business manuals and various regulatory documents ● Those considering the use of AI for promoting DX and talent development ● Those struggling with knowledge inheritance in quality assurance and technical departments In the first part, we will discuss actual implementation cases, and in the second part, we will provide a detailed explanation of the potential of "WisTalk" through product introductions. We hope you will join us!
