Carbon nanotubes (hereinafter referred to as CNT) are advanced materials discovered in Japan, characterized by their lightweight, high strength, and excellent elasticity and conductivity, which are being utilized in industrial products. However, CNTs have a tendency to aggregate, making it difficult to uniformly disperse them in resins or liquids. Achieving a stable and uniform dispersion is a challenge to fully realize their original performance. Our company has been developing CNT dispersants based on research results from universities and companies, utilizing our unique polysaccharide extraction technology. We are pleased to announce that we have completed the technological development for commercialization and will begin manufacturing and sales.

In the midst of the COVID-19 pandemic, while I want to rush to the site immediately, I have to change from using the train to another mode of transportation due to restrictions on going out and the need to avoid crowded places. A new lifestyle that takes into account the novel coronavirus is being demanded. Work and meetings are conducted via telework, and site inspections are facilitated by the remote monitoring tool S-BOX, contributing to operational efficiency. S-BOX is a smart remote monitoring tool that packages communication functions into one. It requires no complicated installation work; simply turning it on starts recording immediately. The surveillance camera from Seiwa Electric, S-BOX, monitors various risks remotely, ensuring "safety" and "peace of mind" 24 hours a day. S-BOX diligently monitors and quickly verifies any issues at various sites, including: - Accidents and theft - Illegal dumping - Squatting - Abnormal troubles - Natural disasters - High waves and flooding Its adoption is expanding across various industries: - Transportation and logistics - Construction - Warehousing and logistics With your devices (computer, smartphone, tablet), you can monitor "sites" nationwide collectively, upgrading your company's operational efficiency at a low cost.

Hoshi and Electric Co., Ltd. has been supplying lighting fixtures for numerous roads and tunnels since 1957, when it delivered lighting fixtures for the Kanmon Tunnel, the world's first underwater tunnel at that time. In 2010, it supplied Japan's first LED tunnel lighting fixtures for the Enoura Tunnel, which is under the direct jurisdiction of the Ministry of Land, Infrastructure, Transport and Tourism, continuously leading tunnel lighting in Japan. The newly developed tunnel LED lighting system, the first of its kind in Japan, features a power supply unit installed inside the electrical room, providing direct current to the lighting fixtures in the tunnel. This innovation allows for the miniaturization and lightweight design of the fixtures. While conventional products had the power supply unit within the fixture itself, this new product does not, enabling a reduction in size and significantly easing installation work. Additionally, by consolidating the power supply unit in the electrical room instead of within the fixture, maintenance has been simplified. Recently, we have supplied the tunnel LED lighting system for the Kyuuzan Tunnel (downhill L=1,704m) on National Route 185, under the jurisdiction of the Hiroshima National Route Office of the Chugoku Regional Development Bureau, Ministry of Land, Infrastructure, Transport and Tourism.

Hoshi and Electric Co., Ltd. has been supplying lighting fixtures for numerous roads and tunnels since 1957, when it provided lighting for the Kanmon Tunnel, the world's first underwater tunnel at that time. In 2010, it supplied Japan's first LED tunnel lighting fixtures for the Enoura Tunnel, which is the first LED tunnel lighting for national highways directly managed by the Ministry of Land, Infrastructure, Transport and Tourism, continuously leading tunnel lighting in Japan. The newly developed tunnel LED lighting system, the first of its kind in Japan, achieves miniaturization and weight reduction by installing the power supply unit inside the electrical room and supplying power to the lighting fixtures in the tunnel with direct current. While conventional products had the power supply unit within the fixture itself, this product allows for miniaturization since the power supply unit is not inside the fixture, significantly reducing installation work. Additionally, by consolidating the power supply unit in the electrical room rather than inside the fixture, maintenance has been simplified. The direct current-powered tunnel LED lighting adopts both the technology registered in the Ministry of Land, Infrastructure, Transport and Tourism's New Technology Information System (NETIS) (CG-170008) and the technology for compact and lightweight LED tunnel lighting fixtures (TH-150008).
