• Ceramics

Microporous ceramics: Capable of producing pores with a minimum diameter of φ0.02mm. New possibilities opened up by pilot microporous ceramics.

For pores with a diameter of less than 1mm, it is generally considered difficult to create deep holes of 10mm or more using drilling or laser processing. Our company can manufacture deep holes of over 100mm in length with an inner diameter of φ0.02mm using high-precision extrusion molding. The dimensional tolerance for the inner diameter is ±5%, and due to the nature of extrusion molding, the variation within the same lot is small. We can also create through holes with combinations of different shapes and hole diameters, allowing for structures with varying wall thicknesses from thin to thick. The materials used are high-purity alumina, zirconia, and aluminum nitride. 【Features】 ■ Capable of producing holes from φ0.02mm to a length of 100mm using our unique technology ■ Can manufacture deep holes with freely adjustable wall thicknesses from thin to thick *For more details, please refer to the materials. Feel free to contact us with any inquiries.

Microporous ceramics: Production of minimum pore diameter Φ0.02mm is possible.

In general, for drilling and laser processing, it is considered difficult to create deep holes with an aspect ratio (depth/inner diameter) of 10 or more for holes with a diameter of less than 1mm. Our company is capable of producing items with an aspect ratio of over 200 using advanced extrusion molding. Additionally, we can manufacture with a free wall thickness, and for "thin-walled pipe shapes," which are prone to deformation and uneven wall thickness, we can produce with a wall thickness of 0.1mm and a length of 100mm (when the outer diameter is Φ1.3mm). The materials used are alumina, zirconia, and aluminum nitride. 【Features】 ■ Capable of producing holes from Φ0.02mm to a length of 100mm using our unique technology ■ Can manufacture deep holes with any wall thickness, from thin to thick ■ Contributes to stable flow rates and pressure loss reduction in fluid control components with stable inner diameter dimensions *For more details, please refer to the materials. Feel free to contact us with any inquiries.

High-precision processing with ±1μm accuracy supports a variety of parts and materials such as discharge guides and positioning pins.

In recent years, there has been a trend towards miniaturization of products, leading to a demand for precision processing of small components. Do you have any concerns regarding this? Our company, "Secondary Process Products," performs secondary processing on high-density, high-strength, and high-purity fan ceramics with sub-micron precision machining. We also accommodate high-precision surface finishing and the assembly of sleeves and parts with special hole diameters. 【Features】 - Capable of producing small diameters of less than 1mm with an aspect ratio of over 200. - Fine and high aspect ratio holes that penetrate in the extrusion direction. - Can be manufactured with a freely adjustable wall thickness, from thin to thick. *For more details, please refer to the materials. Feel free to contact us with any inquiries.

• Processing Contract

For controlling the flow rate of gases and liquids. Achieving stable flow and reduced pressure loss.

The pilot's "porous ceramics" can create numerous through-holes for extrusion molding. It is possible to mold thin ceramics with a minimum outer diameter of φ0.3 mm, fine-pore ceramics with a minimum pore diameter of φ0.02 mm, and through porous ceramics with over 100,000 holes. These are used in fields such as analysis, automotive, and semiconductors. 【Features】 ■ Even for pores with a diameter of less than 1 mm, it is possible to produce items with an aspect ratio of over 200. ■ High aspect ratio holes are penetrated in the extrusion direction. ■ Since the holes are straight and pass through a dense body, stable flow rates can be achieved. *For more details, please refer to the product catalog available for PDF download. Feel free to contact us with any inquiries.

• Ceramics

It is possible to manufacture small-diameter rods and fine-pore pipe shapes.

Generally, there are many flat or sheet-like products, but are there any parts that require rod or pipe shapes? Our "Aluminum Nitride" utilizes the extrusion molding technology of mechanical pencil leads and can be produced in aspect ratios of 200 or more. "Aluminum Nitride" possesses an extremely high thermal conductivity among ceramics and is an excellent material for electrical insulation and thermal radiation. The available sizes can be manufactured in an outer diameter of φ0.5 to φ6.0, an inner diameter of φ0.02 to φ4.0, and a length of 100mm. [Features] ■ For parts requiring heat dissipation ■ Superior thermal conductivity compared to alumina and zirconia ■ Capable of forming small-diameter pipes with fine pores *For more details, please refer to the materials.

[Instructor] Paulstar Communications Inc. Representative Director Koji Kita [Key Lecture Content] Have you ever felt that, despite entrusting work to Generation Z and young employees, they "don't seem to get started," "don't lead to the expected results," or "it's ultimately faster to do it myself"? Behind these situations are various factors, including the recognition gap between supervisors and young employees regarding "entrusting and being entrusted," how to communicate the purpose of the work, the approach, and the scope of discretion, as well as how to follow up after delegating tasks. In this seminar, we will practically explain "how to delegate work" to elicit proactive behavior, taking into account the perspectives and behavioral characteristics of Generation Z and young employees. We will share specific management techniques to help supervisors break free from the burden of work, encourage the autonomy and growth of young employees, and steadily lead to results.

[Speaker] Yoichiro Okuyama, Senior Researcher, Research Department, Hamagin Research Institute, Inc. [Key Lecture Content] In China, the operation of autonomous taxis began in 2021, and now fully unmanned robo-taxis are running in cities like Beijing and Shenzhen. Experiencing a ride reveals the evolution of technology through natural acceleration, smooth steering, and seamless deceleration. Currently, there are several thousand vehicles in operation, but projections suggest that by 2030, this number could exceed one million, accounting for 70% of the global total. What are the underlying factors driving the social implementation of robo-taxis in China? By incorporating local test ride experiences, we will analyze the revenue situation of robo-taxi operating companies and the outlook for market expansion based on data, exploring their future potential. [Lecture Items] 1. Personal experiences of test riding robo-taxis in China 2. Trends in the market size of robo-taxis in China and globally 3. Background of the advancing social implementation of robo-taxis in China 4. Public acceptance and actual usage 5. Performance and challenges of major robo-taxi companies 6.
