Analysis of Functional Ingredients (Anti-Obesity Agents) in Beverages and Foods

In Japan, since April 2015, the nation started the “Foods with Functional Claims (FFC)” system to help general consumers obtain correct information and wisely select foods. A FFC product package clearly shows that it is a FFC product and describes its claimed functionalities. FFC can be obtained by submitting the necessary documents to the consumer affairs agency. The submission does not require any national examination to prove ingredient’s safety nor functionality. FFC is approved, as long as the producer states the functionality of the food based on scientific evidences and be responsible to the statement. In March 2021, there are more than 3,500 submitted FFC. It can be said that the FFC market is keep expanding.

In this application, we optimized analytical conditions for the analyses of functional food ingredients – especially focused on anti-obesity agents that are registered as functional food ingredients in the database and which are used in commercial beverages and foods.

news | 10 March 2022
Tag: Business Other

Showa Denko K.K. (SDK) (TOKYO: 4004) announces that it was resolved at the Board of Directors meeting held today that SDK will set the firm name of a new company (the newly integrated company) which is planned to be organized in January 2023 as a result of integration of SDK and Showa Denko Materials Co., Ltd. (SDMC), which is a member company of the Showa Denko Group, as in below. Execution of this resolution is subject to adoption of relevant resolutions by shareholders at an extraordinary general meeting of shareholders of Showa Denko K.K., which is planned to be held in late September 2022, and is also subject to adoption of relevant resolutions by shareholders at an extraordinary general meeting of shareholders of SDMC, which is planned to be held in late September 2022.

We will announce the details of this matter including changes in articles of incorporation as soon as they are decided.

1. Firm name of the Newly Integrated Company

Resonac Corporation

As stated in the news release titled “Showa Denko Group Starts to Consider Transformation into Holding Company Structure,” which is announced at the same time today, we will consider transformation of our company structure from the current one into holding company structure. In this plan, we will set the current Showa Denko K.K. as a company to be split, execute the company split, make Showa Denko Materials Co., Ltd. (SDMC), which is a wholly owned subsidiary of HC Holdings K.K. (HCHD), in which SDK holds 100% of voting rights, succeed all businesses currently operated by SDK, and merge HCHD into SDMC. Then we will set SDMC as a company to be split, execute the company split, and make SDK succeed a part of SDMC’s assets and liabilities.

If execution of this plan is finalized, firm names of the holding company and the manufacturing company will be set as follows.

Holding company (current Showa Denko K.K. (planned)): Resonac Holdings Corporation
Manufacturing company (current Showa Denko Materials Co., Ltd. (planned)): Resonac Corporation

2. Corporate logotype

3. Reason for change in the firm names

In January 2023, SDK and SDMC will cooperatively transform themselves into a holding company structure, in which the holding company will specialize in formulating and executing group strategy, and functioning as a company listed on the stock exchange, and the newly integrated company (a company involved in manufacturing) will focus on strengthening competitiveness of each business of the Company in order to realize synergy of integration of SDK and SDMC as soon as possible, and operating businesses in a quick and flexible manner corresponding to the surrounding environment. The newly organized corporate group will aim to become a “Co-Creative Chemical Company,” which will have global top-level competence as a chemical manufacturer, make decisions and act swiftly and flexibly, and co-create better society with key players in various industries and consumers who share a high aim and ideal with us. In order to take a new step as the newly integrated company and realize Co-Creative Chemical Company, we decided to change the new company’s name into “RESONAC” concurrently with the integration of the two legal entities.

The Showa Denko Group sees the integration as “the second foundation” for SDK and SDMC. Under the new firm names, the brand-new Resonac Group will ferment the sense of unity further, create new functions required of the time as an advanced material partner, and contribute to sustainable development of global society.

4. Our hope put into the new firm name and corporate logotype

The new firm name “RESONAC” was created as a combination of two English words, namely, the word of “RESONATE” and “C” as the first letter of CHEMISTRY. Into RESONAC, we put our hope that the Group’s wide-ranging and flexible advanced material technologies will be connected and resonate with our partners’ various technologies and ideas to realize bright future, and the resonance will spread further to meet new partners, thereby creating a powerful surge that changes society.

To express this hope of ours, we put two parallel lines that rises steadily from left to right into the lower left of the first letter R in the new corporate logotype. These parallel lines symbolize co-creation borne by resonance, and also symbolize our strong will to spread the resonance further and challenge to realize bright future together with our partners.

5. The scheduled date of changes in firm names

January 1, 2023

Showa Denko Drastically Accelerates Exploration of Optimal Formulation of Semiconductor Materials with Quantum Computing Technology

news | 07 March 2022
Tag: Semiconductor

Showa Denko K.K. (SDK) (TOKYO: 4004) (President and CEO: Hidehito Takahashi) has demonstrated the ability of quantum computing technology to accelerate the exploration of the optimal formulation of semiconductor materials, reducing the exploration time from dozens of years of conventional methods to dozens of seconds.

Semiconductor materials contain numerous ingredients such as resins, fillers, and additives in various mixing ratios, and high-performance materials are obtained by optimizing the formulation. However, the theoretical number of combinations of ingredients and mixing ratios to be analyzed is more than 1050. Thus, it will take more than dozens of years to explore all possible combinations of these ingredients and their mixing ratios with conventional artificial intelligence (AI) methods. Therefore, we had analyzed only part of theoretically possible combinations before.

To reduce the time required for the exploration, we focus on using high-performance computing technology, Digital Annealer*1, a quantum-inspired technology*2 developed by Fujitsu Ltd. (Representative Director and CEO: Takahito Tokita). Showa Denko has developed an AI model for predicting the properties of semiconductor materials from complex formulation conditions. To make the AI model computable on Digital Annealer, Showa Denko has expressed the AI model as an Ising model*3, one of the statistical mechanical methods. By simulating the Ising model on Digital Annealer, we have reduced the exploration time to dozens of seconds, about 72,000 times faster than the time required by conventional AI methods, where the type and amount of ingredients to be explored are limited for conventional AI methods. Moreover, the optimal formulation designed with the Ising model is expected to obtain semiconductor materials with 30% higher performance than the formulation designed with conventional AI methods.

In its “Long-term Vision for Newly Integrated Company,” the Showa Denko Group has announced that it will commit itself to research and development of AI and computational science, which is the core of its fundamental R&D activities. The result of this development is an example of achievements of R&D activities based on the application of “Chemistry to Think” on “Chemistry to Formulate,” both of which the Group has defined its basic frameworks for technological development. The Group will apply this development to various materials, accelerate our development activities, and provide our customers with solutions for their problems, thereby contributing to a sustainable society.

*2: Quantum-inspired computing technology: High-performance computing technology inspired by quantum technology, though not directly using quantum effects.

*3: Ising model: A statistical mechanical model for describing the behavior of spins in magnetic materials. The model describes the macroscopic magnetization of a magnetic material by considering the interaction between the spins and the coupling to the external magnetic field. The model is applied to a wide range of research areas, including combinatorial optimization problems.
