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.

• Contract manufacturing

Ceramics used in high-temperature environments, including electronic components and automobiles. Here are examples of processing alumina, zirconia, silicon nitride, and silicon carbide!

Yakeshi Electric Co., Ltd. offers processing of "ceramics." Ceramics possess excellent wear resistance, heat resistance, and insulation properties, making them suitable for use in electronic components, semiconductor manufacturing equipment, automobiles, and aerospace applications in high-temperature environments. Additionally, ceramic components are strong and have excellent chemical resistance, which allows them to be used in medical devices as well. 【Main Materials Handled】 ■ Alumina (Al2O3) ■ Zirconia (ZrO2) ■ Silicon Carbide (SiC) ■ Silicon Nitride (Si3N4) ■ Quartz Glass (SiO2) *For more details, please refer to the related links or feel free to contact us.

• Ceramics

Our products are used in industrial magnetrons, analyzers, X-ray devices, catheters, semiconductor manufacturing equipment, electric propulsion systems, air purifiers, sterilization lamps, and more.

Rare metal materials such as tungsten, molybdenum, and tantalum, which possess properties like heat resistance, corrosion resistance, and high strength. These materials are difficult to process, and there are only a few companies that handle them. Our company develops and manufactures "functional components" using these rare metal materials, aiming for further improvements in low work function, long lifespan, and high-performance stabilization. ◆ Achievements - Analysis - Mass spectrometers (electron guns, electron sources) - Semiconductor manufacturing equipment - (ion implantation) - Medical - CT scanners (X-ray sources) (catheters) - Space - Ion engines, Hall thrusters (heaters) - High-temperature furnaces - (reflectors) (heaters) (structural components) and more ◆ Technology - Coating (yttria, alumina, PTFE, etc.) - Material development using heat treatment furnaces with a maximum temperature of 2700°C - High-precision, high-aspect-ratio precision machining - Coils of various shapes - Joining of metals and more

[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. Will robo-taxis become widespread in Japan as well? 7. Q&A / Business card exchange
