Development of materials such as tungsten porous materials. The porous section utilizes capillary phenomena to inject special liquids for functional materials.

Development of materials such as tungsten porous materials. The porous part utilizes capillary phenomena to inject special liquids, making it a functional material. It can also be made lightweight. Gakuseki Electric has developed materials such as tungsten in collaboration with domestic and international material manufacturers to suit various applications. We have particularly focused on the development of doped tungsten with excellent high-temperature properties, as well as ultra-high purity tungsten such as 5N and 6N. However, there is still a strong demand from customers to develop materials with special functions in small quantities for even more specialized applications. To meet this demand, we have prepared material manufacturing equipment suitable for small-scale production and assist in the development of new materials from raw material procurement to condition setting and mass production support. *For more details, please refer to the catalog or feel free to contact us.

Conducting genuine trial and error with agility! Our approach to development.

To achieve low-energy discharge, the electrodes must be made of materials with a low work function. One method is to add oxides and manufacture them through sintering; however, if there are too many oxides, the sintering temperature for tungsten may differ, which can result in insufficient sintering conditions. In such cases, tungsten alone can meet the necessary sintering conditions and maintain its physical properties at a high level. Subsequently, emitters that have been manufactured separately and can add easy discharge properties are impregnated into the sintered tungsten, ultimately resulting in a state where both are physically and chemically bonded. To realize this, hundreds or thousands of patterns must be repeatedly experimented with and developed. This diligent trial-and-error approach, carried out with agility, is the attitude and characteristic of our company's development efforts. *For more details, please refer to the external link page or feel free to contact us.*

Due to the ample temperature range, it is possible to completely remove impurities, including areas where the temperature is less likely to rise.

To promote crystal growth without allowing hydrogen molecules to enter the grain boundaries, a high vacuum environment was necessary. Additionally, to achieve secondary recrystallization of potassium-doped tungsten, it was also required to heat the workpiece itself to over 2000°C. As a result, we developed the equipment in-house. The first model achieved a work temperature of up to 2000°C, and the subsequent third model reached up to 2800°C. This equipment is utilized not only for the manufacturing of halogen lamp components but also for various manufacturing processes that require ultra-high temperature treatment. In particular, it has become indispensable for the removal of strong impurities, such as alumina for medical components and electrodes for ultra-high pressure mercury lamps. *For more details, please refer to the external link page or feel free to contact us.

This is an introduction to a case study of molybdenum (Mo) processing. =============================== From a Φ25 cylinder with Φ2 and M3 screw holes, it is machined as a single piece up to the upper grid. The grid has a Φ16 hole with a diameter of 1.2, and the thickness is 0.3 ± 0.02. =============================== Parts that were originally separate can sometimes be proposed as a single integrated piece, considering the usage environment and cost. While machining rare metals can sometimes waste materials, there are often advantages such as <lower overall costs> and <not having to worry about joining methods>. If you have parts with such challenges, please feel free to consult with us!

Precision machining of tungsten, a difficult-to-cut material, into the smallest screws suitable for mass production.

We challenged ourselves to create the smallest size of tungsten screws using NC automatic lathes. We are machining from tungsten rods with a diameter of φ2 and lengths of 1000 to 2000L. As the size decreases, it is necessary to use thinner cutting edges. Thinner cutting edges lead to shorter tool life and a higher likelihood of chipping. We have optimized various materials and shapes, from commercially available tips to brazed tools. =============================== 【Processing Examples】 ● Total length 17L ● Central part M3 coarse pitch P0.5×3mm (Above) ● End part M2 fine pitch P0.25×7mm (Below) ● End part M1.6 coarse pitch P0.35×7mm =============================== Our company has a long history in the field of small and micro machining. We provide one-stop solutions from initial experiments and development to small batch production and mass production. For precision machining of difficult-to-cut materials and high melting point metals, please leave it to us!

[Lecturer] Professor Hiroyuki Kato, Faculty of Sociology, Department of Social Policy Science, Hosei University [Key Lecture Content] In this lecture, I will introduce perspectives on the shipbuilding industry. Japan's shipbuilding industry has a long history and can be seen as a "microcosm" of Japanese industry. Within about ten years after World War II, Japan's shipbuilding industry became the world leader in construction volume, and at one point, the construction volume of the seven major domestic companies accounted for more than half of the world's share. Although it has since been surpassed in construction volume by latecomers such as South Korea and China, it still maintains a certain level of competitiveness. Reflecting on the path taken by the shipbuilding industry, which serves as a "microcosm," the reasons for its continued strength, and the challenges it currently faces may provide insights when considering the future of various Japanese industries. [Lecture Items] 1. Characteristics of the shipbuilding industry 2. Shipyards seen through photos and videos 3. The shipbuilding industry depicted in films 4. Why is it still strong? 5. Points to consider for future developments 6. Q&A / Business card exchange

[Speaker] Maho Tanaka, Manager, Strategy Group, Business Consulting Division, Accenture Japan Ltd. [Key Lecture Content] AI is evolving beyond a mere tool for operational efficiency to become an entity responsible for execution, including information acquisition, comparison, judgment, contracts, and purchasing. As actions initiated by dialogues with general-purpose AI chatbots like ChatGPT become mainstream, corporate information is not reaching users directly, and the structure where decision-making and execution are completed on AI is rapidly expanding. In this lecture, based on this irreversible change, we will organize the reality that the competitive axis of companies is shifting from "appealing to consumers" to "how AI understands, selects, and executes." Furthermore, we will explain the key points of strategic transformation that management should consider in the era of agent-based AI, from organizing the information structure cited by AI to designing touchpoints that reclaim the initiative for judgment and execution for the company. [Lecture Items] 1. The impact of AI on information search and access 2. The impact on corporate marketing and communication 3. The ideal direction for corporate communication in the AI era 4.

[Speaker] Andy Mochizuki, Director, Deloitte Tohmatsu TMT Division / Monitor Deloitte [Key Lecture Content] In an era where thinking is commoditized by AI, the source of value is determined not by "information" but by "existence," that is, "the meaning of your being." This course will start from the environmental changes surrounding the AI era, exploring the concept of redesigning work in a purpose-driven manner, the type of thinking required in the AI era (QADI cycle), and delving into the absolute differentiating factor that only humans possess—"embodiment." We will update our sense of purpose in the AI era and our collaborative relationship with AI, initiating a transformation to "live anew" from here. [Lecture Items] 1. Mapping Environmental Changes - "From the Era of Information Asymmetry to the Era of Existence Asymmetry" 2. Redesigning Work in a "Purpose-Driven" Manner 3. The "Thinking Models" Necessary in the AI Era 4. The "Body" as an Absolute Differentiating Factor 5. How to "Live Anew" in the Coming AI Era 6. Q&A / Business Card Exchange
