Delivery Title: Development of a "Slim Trench" with Indicator Function Furukawa Electric Co., Ltd. has developed a surface-mounted cable trench (indicator trench and flat trench) with an indicator function that can be installed on the road surface. ■Background■ In Japan today, discussions are underway for smart cities aimed at optimizing infrastructure and facilities to enhance convenience and comfort. In smart cities, various electronic devices are installed throughout the urban area, while communication and power cables, as well as water and gas lines, are buried beneath the pavement. One of the challenges in smart cities is to install new equipment while avoiding these existing facilities and ensuring cable routes. ■Product Features■ This product has a thickness of 55.5mm, which is about half the thickness compared to the minimum size class of 130mm for concrete cable trenches, allowing for a reduction in the amount of ground excavation. This thickness is comparable to paving materials such as interlocking blocks and tactile paving blocks, enabling replacement with existing paving materials without significant changes to the foundation. Additionally, by integrating the indicator and cable conduit, simple installation is possible.

Mr. Yamamoto is responsible for the overall safety management operations of the company at the Safety and Environment Department of Special Spring Industry Co., Ltd. "There are first-class rivers, the Inagawa River and the Darokugawa River, flowing near our factory, and there is a risk of these rivers flooding when typhoons or linear precipitation zones occur. In fact, a major typhoon passed through Hyogo Prefecture in 2018, and at that time, the situation was very close to a river flood. Therefore, it was necessary to present a sufficient BCP (Business Continuity Plan) to our customer, the automobile manufacturer, in preparation for potential river flooding." "The foldable water stop board F-shield is lighter than sandbags, making it easy to transport and set up. Unlike sandbags, there is no need for the cumbersome task of filling or emptying water; it can be easily set up and taken down by simply locking the fittings." A new disaster prevention warehouse has been established right next to the factory's main gate, where the foldable water stop board F-shield is stored, ensuring that it can be set up immediately in case of an emergency. "I would like to win the trust of our customer, the automobile manufacturer, by presenting a sufficient BCP (Business Continuity Plan) in preparation for river flooding."

● Developed and launched a bell block specifically for on-site hand holes in tunnels, designed for square EFLEX. ● Improved workability by changing the material from resin concrete to resin, resulting in approximately half the product weight. ● Contributed to the development of road infrastructure by shortening construction periods for tunnel work using square EFLEX. As a new addition to the multi-line square EFLEX series, we have developed and launched the Bell Block Lite, which can contribute to shortening construction periods for tunnel cable installation. Compared to the conventional resin concrete bell blocks, it is approximately half the weight, which is expected to enhance labor efficiency. Additionally, while the current mainstream wall thickness for on-site hand holes in tunnels is 150mm and 200mm, the previous resin lineup required a 50mm recess at the connection part of the hand hole bell block for a wall thickness of 200mm. With the addition of a type that accommodates a wall thickness of 200mm, it will now be possible to handle hand holes with a wall thickness of 200mm without the need for recessing.

**Expert in Power Distribution Board Manufacturing: Takahashi Electric Co., Ltd.** Mr. Watanabe works in the General Affairs Department of Takahashi Electric Co., Ltd., which is responsible for the manufacturing of power distribution boards that are indispensable in modern social infrastructure. **Risk of Rainwater Intrusion into the Factory! Safety Measures and Risk Management at the Sheet Metal Factory** "At the entrance of our sheet metal factory, a small forest is encroaching, and during typhoons or heavy rain, there is a risk that rainwater will flow from the forest into the factory entrance. Since there are expensive equipment such as laser processing machines inside the factory, it was necessary to implement risk management to prevent rainwater from entering the factory entrance. We considered stockpiling sandbags, but they are heavy and deteriorate quickly, causing the contents to spill out. Therefore, we concluded that sandbags were insufficient as a safety measure for the factory." **Preparing for Flood Damage to the Factory with the Folding Water Stop Board F-shield** "The folding water stop board F-shield is easy to handle because it is foldable, allowing for timely storage and movement. Additionally, its bright yellow color enhances visibility, which is also appealing. I like that it is more durable compared to sandbags, making it user-friendly."

Mr. Kamiyama is involved in the management of two companies: Miyauchi Construction Co., Ltd., which is engaged in the construction industry, and Koshiki Fruit Garden Co., Ltd., which is involved in the production, processing, sales, and café operation of passion fruit. "The area around our company is at a low elevation, and due to the phenomenon known as 'abiki,' the road can become flooded as the sea level rises and falls repeatedly in a short time. Three years ago, for the first time, we piled sandbags in front of the fruit processing factory, but it was a very challenging task. The occurrence happened around 8 PM, and I had been drinking, so I couldn't drive the truck. Therefore, I asked a colleague to transport the sandbags stored in the fire department's warehouse by car. 'Abiki' can cause the water level to rise in about 30 minutes. I felt that there wouldn't be enough time to go and get the sandbags and stack them." "The foldable water barrier F-shield takes up little space when stored folded and can be set up quickly. It is lightweight, making it easy for elderly women working at our processing factory to handle, and it looks better than sandbags, so we can safely place it in visible areas. I want to be well-prepared for sudden 'abiki' with the foldable water barrier F-shield."
