We will exhibit at Nepcon Japan from January 22 (Wednesday) to January 24 (Friday), 2025 / Display of high-performance rare metal components.

Metals and ceramics: We will propose the optimal heat treatment tailored to your needs!

Generally, high-temperature heat treatment takes several hours, which can be costly and time-consuming. Gakuseki Electric has been conducting heat treatment of high melting point metals and ceramics, including tungsten. In particular, to quickly and efficiently perform heat treatment for small, low-volume, and diverse products, we have repeatedly conducted various experiments and successfully developed a high-speed high-temperature vacuum furnace capable of reaching approximately 2700°C. With this equipment, ■2500°C for 30 minutes ⇒ The entire process from the start of heating to cooling down is completed in about 2 hours! We have achieved efficiency and cost reduction. Additionally, substances that cannot be completely removed in general furnaces can also be heated and removed. ーーー We also accommodate various high-temperature heat treatments, including multi-atmosphere sintering furnaces and forming gas flushing furnaces. Through these high-temperature heat treatments, it is possible to ultimately prevent the residue and contamination of impurities. With decades of accumulated experience and know-how in heat treatment, please leave the heat treatment of metals to Gakuseki Electric. ーーー

• Processing Contract

Contributing to cost reduction with 45 years of technological expertise and original automated equipment.

Tungsten and similar materials have a significant coil back (spring back), but with our years of expertise, we can accommodate various designs and shapes. ◆ We can manufacture a wide variety of coils, from fine wires of a few microns to thick materials. Supported sizes (example): Wire diameter Φ0.01 to 5mm (subject to consultation) ◆ Coiling machine with automatic tension adjustment feature Due to changes in material weight, the back tension differs between the start and end of winding. To produce uniform filaments, a consistent tension must be maintained, and we have our original coiling machine that automatically controls the back tension. ◆ Cost reduction with servo-controlled mandrel-less forming machine For various coil shapes, our NC-type coiling machine allows control simply by inputting design values, making fine adjustments easy. We essentially design all equipment in-house, ranging from fully automatic to semi-automatic machines. ◆ Reliable technological capabilities trusted overseas We have a long history of exporting coils related to lighting and analytical instruments to European and American countries.

From prototyping to mass production of difficult-to-machine materials such as tungsten, molybdenum, and tantalum.

We perform precision machining of difficult-to-cut and difficult-to-process materials such as tungsten, molybdenum, and tantalum. For mass production, we automate the process using feeding machines, while for prototypes ranging from one to a few pieces, we respond quickly with manual operations. In particular, precision machining of small products with tolerances in the micron or millimeter range is our specialty. ◆ Precision machining using NC lathes and other machine tools We utilize NC lathes, MC multi-tasking machines, milling machines, centerless grinders, automatic precision cutting machines, wire-cut and electrical discharge machines, automatic surface grinders, injection molding machines, extrusion molding machines, and presses. ◆ In-house automatic assembly and processing machines We have a wide range of in-house developed fully automatic machines, including fully automatic hot press machines, automatic heater coil assembly machines, and fully automatic electrode assembly machines. Gakuseki Electric often takes on the manufacturing of products that other companies are reluctant or unable to produce. If there are no machines available in the market for manufacturing, we design and build our own processing machines. ◆ Processing - Cutting - Machining - Milling - Cutting - Tapering - Drilling *Sizes, precision, and handled materials are detailed in the "Basic Information" section.

[Speaker] Masashi Sugita, President and CEO of LEX Style Co., Ltd. [Key Lecture Content] The power consumption of AI servers used in data centers has significantly increased, making traditional air cooling insufficient for operation. This lecture will organize the requirements for introducing a liquid cooling system into air-cooled data centers and explain the implementation method using free cooling with specific design details. When handling high-density AI servers, energy efficiency is required, and the widely used energy efficiency indicator, as well as the Ministry of Economy, Trade and Industry's Resource and Energy Agency's PUE regulation of "1.3 or below," will be explained along with practical operational insights. [Lecture Items] 1. Heat dissipation methods for high-density, high-heat AI servers 2. Basics and importance of PUE/pPUE 3.

[Instructor] Yuichiro Kabushiki, Partner Lawyer at TMI Comprehensive Law Office [Key Lecture Content] With the spread of AI, there is growing attention on the civil liability of developers, providers, and users of AI. The Ministry of Economy, Trade and Industry will publish "Guidelines on the Interpretation and Application of Civil Liability in AI Utilization" in April 2026, and the Ministry of Justice will also establish an expert meeting to examine civil liability related to unauthorized use of images and voices generated by AI in the same month. As the full enforcement of the AI Promotion Act and the revision of AI guidelines are underway, it is necessary to design and operate governance based on the potential responsibilities that may arise retrospectively. In this seminar, based on the guidelines from the Ministry of Economy, Trade and Industry and drawing on litigation practice experience as a judge and lawyer, we will organize the basic framework for assessing civil liability and explain fundamental methods for designing and operating governance based on risk analysis. Furthermore, we will examine the framework for civil liability and the design and operation of governance using hypothetical cases that are likely to pose practical issues.

In this seminar, we will welcome Mr. Satoru Hayami from Waseda University, who will explain the latest trends in AI utilization in manufacturing, as well as the evolution of technologies such as agent-based AI and physical AI, and the opportunities and key points for practical application in the manufacturing industry. Furthermore, Mr. Tsubasa Shibata, representative of Next Opt, will introduce processes aimed at practical implementation, incorporating actual case studies from manufacturing sites. We hope you will envision the "potential for AI utilization in your company" and take home hints that will lead to improvements in your operations starting tomorrow. We look forward to your participation.
