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] Kazuharu Yamamoto Partner Expert, Roland Berger Co., Ltd. [Key Lecture Content] In the automotive industry, the topic of EVs is ever-present. The advancement and promotion of EVs is a significant goal for achieving carbon neutrality (CN). On the other hand, the realization of CN and the progress of EVs are inseparable topics related to the realization of a circular economy (CE). In this lecture, I will present an overview of CE and CN, discuss the mechanisms of CE progressing in Europe, and the reverse supply chain, while also addressing the expansion of EVs and charging infrastructure from a consumer perspective. [Lecture Items] 1. Overview of CE and CN in the automotive industry and EVs 2. Mechanisms for achieving CE in Europe 3. Expansion of EVs and charging infrastructure (Characteristics of Japan within the global context) 4. Q&A / Business card exchange

[Speaker] Mitsune Shirasawa, Partner Attorney at TMI General Legal Practice [Key Lecture Content] The regulations that must be complied with when implementing payment businesses are defined by various laws, and it is common for the applicable laws to change due to subtle differences in the schemes adopted. Therefore, when building a business related to payments, it is essential to have not only an understanding of individual laws but also a cross-sectional understanding of how these laws interact with each other. Additionally, recent developments such as the categorization of money transfer businesses, the introduction of regulations regarding stablecoins, the clarification of payment collection services, and the emergence of new schemes like BNPL (Buy Now Pay Later) and BPSP (Business Payment Service Provider) have led to significant advancements and complexities in payment-related businesses. Thus, this seminar will provide a comprehensive explanation of the current regulations surrounding payment businesses and their practical responses. [Lecture Topics] 1.
