In the face of uncertainty regarding future energy supply, we are advancing efforts towards high-efficiency "electrification" and "hybridization" based on gas combustion furnaces.

**Electrification of Thermal Equipment** In an uncertain future for energy supply, we are responding to high-efficiency electrification based on proven thermal equipment (combustion furnaces) to offer multiple options to our customers as an industrial furnace manufacturer. □ Our electric hot air generator (AH-E) can be substituted for our gas combustion type, allowing for electrification without significant changes to the equipment layout. **Hybrid Heating of Electric and Combustion Types** We have numerous achievements not only in full electrification of thermal equipment but also in hybrid heating that combines the advantages of combustion types. We address challenges such as "securing green power, reducing costs, and ensuring power capacity" through hybrid solutions with combustion types. In addition to enhancing the efficiency of electric systems, we can also implement energy-saving systems that utilize waste heat for gas burners. By incorporating hydrogen gas burners, we achieve carbon neutrality! **We Conduct Practical Verification Tests** We conduct various heating tests at the newly established "Thermal Technology Research Institute" within the Horyuji Center. Among these, the "QCO Test Facility" allows for heating tests using four different heat sources! We propose thermal equipment suitable for your work using gas, electric, hydrogen, and hybrid heat sources.

CLT is known as a building material, but its applications are not limited to just buildings. The wooden lightweight mat "Hyper CLT Mat" is a new option for utilizing CLT in civil engineering. It can be used as a wooden mat in places where steel plates have been the norm, such as temporary roads, access routes, heavy machinery work yards, and material storage areas. The 5×10 mat is relatively light at about 230 kg, making it easy to install, remove, and relocate. Additionally, it offers different values compared to steel, such as reducing glare and metallic noise, as well as CO2 fixation through wood. Moreover, the Hyper CLT Mat is registered with the Ministry of Land, Infrastructure, Transport and Tourism as a NETIS technology "TH-250021-A." It can also be utilized for proposals involving the use of new technologies and environmental considerations in public works. From construction to civil engineering, the new use of wood is expanding in the form of wooden lightweight mats.

Metal cracks are one of the concerns in equipment maintenance operations. Conventional welding methods for repairs can cause changes in the base material around the crack due to heat, leading to residual stress and deformation, which always carries the risk of "crack recurrence" and "secondary damage." Hinode Water Supply Equipment Co., Ltd.'s "Mechanical Stitching Method" is a new technique that allows for the repair of metal cracks without applying heat. By using special bolts and reinforcement plates, the crack is physically removed without affecting the base material at all. Repairs can be made even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. For more details, please contact us or download the catalog.

We have newly added a **"Frequently Asked Questions Q&A"** section to the Hyper CLT sheet website. It clearly summarizes many questions frequently asked by those considering the introduction of the product, such as "What types of civil engineering sites can it be used on?", "Can it be used on rainy days?", "Is it compatible with large machinery?", and "What is NETIS?". The Hyper CLT sheet is a lightweight wooden sheet utilizing wood CLT, suitable for a wide range of applications including temporary roads, access routes, and heavy machinery work yards. It is also registered as a **Ministry of Land, Infrastructure, Transport and Tourism NETIS registered technology "TH-250021-A"**. Since it is a new material, we will not leave any uncertainties unaddressed. We aim to create a website that makes it easy to resolve questions before introduction, including information on wood, NETIS, civil engineering, and CLT, and we will continue to enhance the Q&A section.

We have added a new **"Glossary"** to the Hyper CLT sheet website. In the civil engineering and construction industries, there are many specialized terms such as "CLT," "NETIS," "temporary roads," and "wooden lightweight sheets." Therefore, we have introduced related terms in an easy-to-understand manner so that those who are encountering Hyper CLT sheets for the first time can understand the products and technologies. Hyper CLT sheets are wooden lightweight sheets for civil engineering that utilize wood CLT and are registered under the Ministry of Land, Infrastructure, Transport and Tourism's NETIS technology as **"TH-250021-A."** We hope that by not only conveying the features of the product but also sharing the underlying technologies and terminology, users will feel a closer connection to Hyper CLT sheets. We will continue to enhance our website and provide clear information related to wood, NETIS, civil engineering, and CLT.
