We will be exhibiting at the "High-Performance Materials Week 2018, 3rd High-Performance Ceramics Exhibition"!

From material selection such as ceramics, quartz glass, and high melting point metals to cooperation in new product development, you can rely on us for precision processing of hard and brittle materials.

We perform grinding, cutting, and polishing of various ceramics, quartz glass, and difficult-to-machine materials such as tungsten and molybdenum. With the motto "If it can be processed in iron, there is nothing that cannot be processed in other materials," we have accumulated technology over the years. We primarily use machining centers, owning over 70 three-axis machines and more than 15 five-axis machines, as well as ultra-high precision machines with linear specifications. Additionally, we have a comprehensive range of measuring equipment, including three-dimensional measuring machines, image measuring instruments, and laser microscopes. We have established a quality assurance system, and we can perform cleaning and drying in a clean room, as well as vacuum packaging. Even if there is little experience with ceramics or high melting point metals, we consider factors such as heat resistance, low expansion, high hardness, wear resistance, and electrical insulation to select and propose materials that meet your requirements. If you have new materials or are struggling with processing materials, please feel free to consult with us. 【Business Activities】 ○ Processing and sales of various ceramics and brittle materials such as quartz glass ○ Processing and sales of high melting point metals such as tungsten and molybdenum ● For more details, please download our catalog or feel free to contact us.

Here are examples of processing quartz glass, which can be processed more efficiently than ceramics.

We will introduce examples of processing quartz glass and heat-resistant glass. Quartz glass is softer and can be processed more efficiently than general ceramics. The main point of caution in processing is its fragility, so our company aims to minimize damage to the material during processing as much as possible. Specifically, this involves managing the wobble of the grinding wheel, using high-grit diamond particles, sharp diamond particle shapes, and soft bond grinding wheels. 【Processing Example】 ■Product Name: Shower Plate ■Material Used: Tempax ■Processing Method: MC Processing ■Size: φ2.0, 2,000 holes ■Application: Gas introduction for various manufacturing equipment For more details, please refer to the catalog or feel free to contact us.

Free gift of material property tables! We introduce tungsten, molybdenum, and more.

The "Material Guide" provides descriptions of various materials categorized by their characteristics and types. Materials such as ceramics, as well as high melting point metals like tungsten and molybdenum, exhibit excellent properties such as heat resistance, wear resistance, and insulation. It also introduces semimetals like silicon and glasses such as quartz glass. 【Featured Products】 ○ High melting point metals ○ Ceramics ○ Semimetals ○ Glass, etc. For more details, please download the catalog or feel free to contact us.

[Instructor] Attorney Kurato Suzuki, Irokawa Law Office [Key Lecture Content] Due to the amendments to the Comprehensive Promotion Law for Labor Policies, starting from October 1, 2026, employers will be required to take necessary measures in employment management regarding customer harassment (Kasu Hara) and sexual harassment against job seekers (Job Hunting Sexual Harassment). In line with this, companies will need to prepare for practical implementation before the enforcement date, based on the guidelines published by the Ministry of Health, Labour and Welfare. This includes developing internal regulations, establishing consultation and response systems, raising awareness within the company, and determining judgment and response methods on-site. This seminar will organize the setting of job hunting rules related to job hunting sexual harassment, internal awareness, and key points for regulatory development. It will also explain the distinction between legitimate complaints and customer harassment, judgment, documentation, and response on-site, the establishment of a company-wide system, regulatory development considering dispute risks, and points that are easily overlooked. The Human Resources, Labor, Legal, and Compliance departments will systematically organize the response matters that need to be confirmed in preparation for the enforcement on October 1, 2026, from the perspectives of guideline compliance and on-site operations. [Lecture Items] 1. Job Hunting Sexual Harassment 2. Customer Harassment 3. Q&A

[Speaker] Mr. Itsuki Wakayama, Project General Manager, Technology Promotion Unit, Low Carbon Solutions Division, INPEX Corporation [Key Lecture Content] The greatest advantage of synthetic methane production through CO2 methanation technology is that it enables decarbonization without significant additions or modifications to all existing natural gas and city gas infrastructure. At INPEX, after two NEDO commissioned projects, we have been conducting the development of practical application technology with a capacity of 400 Nm3-CO2/h, one of the largest in the world, as a subsidized project by NEDO since the fiscal year 2021. By the fiscal year 2025, we aim to achieve the injection of synthetic methane produced during the demonstration operation of the test facility. This presentation will provide detailed information on the results of the NEDO project for the fiscal year 2025, including the current status of the latest test facilities. [Presentation Items] 1. INPEX's efforts towards net zero by 2050 2. Policy trends related to CO2 methanation 3. Challenges of CO2 methanation 4. Results of the NEDO practical application technology development project with a capacity of 400 Nm3-CO2/h for the fiscal year 2025 5. Future commercialization prospects and challenges 6. Q&A / Business card exchange

[Speaker] Mr. Satoru Shimizu, President and CEO of Okunote Inc. [Key Lecture Content] Generative AI is not a "magic wand," but a "mirror" that reflects the questions of the user. In this lecture, based on my book "The 'Super' Planning Techniques Practiced by Competition Disruptors: Seven Creative Steps to Lead Winning Strategies with the 'Art of Questioning'," I will explain how to overcome the challenges of proposals being rejected, not moving forward within the company, and not being executed on-site through interactions with AI. I will introduce the entire process of planning, linking it with AI utilization, from question design to hypothesis destruction, structuring materials from the decision-maker's perspective, forming internal consensus, managing execution, and turning reflections into assets. In the latter part of the workshop (exclusive to on-site participants), you will actually formulate questions and refine your dialogue with AI, taking home usable "art of questioning" techniques for tomorrow. [Lecture Items] 1. Orientation: AI is a "mirror," not a "magic wand." 2. Enhancing the precision of planning through "question design" and "hypothesis destruction." 3. Structuring materials from the decision-maker's perspective to create "acceptable" proposals. 4. Forming consensus that transcends internal barriers. 5. Mechanisms that prevent execution from stopping and turning experiences into assets through reflection. 6. Habitualizing AI as a "partner" and the roles humans will take on in the AI era.

【Exhibition Overview】 A collection of products related to data centers, which are at the core of AI infrastructure, gathered in one place.
