Detecting fires in tunnels; can also be used as an alternative to CCTV.

【Points】 Automatically analyzes infrared camera footage to perform fire detection that is comparable to traditional methods. It also has a built-in visible light camera, allowing for tunnel monitoring similar to CCTV.

• Security cameras and surveillance systems

Optimize wind speed in the tunnel, also responsive in emergencies.

This is a ventilation measurement control panel that implements ventilation control for normal and emergency conditions (zero wind speed). It optimally controls the jet fan using measurement data from smoke density meters, carbon monoxide density meters, wind direction and speed meters, and fire detection devices. It is equipped with standard zero wind speed control to ensure a safe evacuation environment for users during emergencies (such as fires). In normal control, it utilizes wind speed to improve the control delay of feedback control.

We continuously monitor temperature changes remotely and provide "visible peace of mind."

Temperature sensors embedded at regular intervals within the cable measure the surrounding temperature every 10 seconds, providing real-time temperature information. This allows administrators to continuously monitor the temperature remotely and respond quickly to abnormal temperature changes. Additionally, in the event of a fire, the system accurately detects the "fire point location" at a minimum interval of 1 meter and provides this information to the administrator. The two-stage detection of preliminary and main alarms eliminates false alarms and is effective as a fire prevention and mitigation measure in conjunction with other disaster prevention equipment. The completely shielded structure of the cable excels in dust and water resistance, making it "maintenance-free." It is already being utilized as a "fire point detection device" in the field of road tunnels, in conjunction with ventilation control systems during fires, and is registered with NETIS.

False alarm elimination: Fire sensor with a completely shielded cable for maintenance-free operation!

The "temperature detection fire point location detection device" is a fire detector with a cable structure that detects fires based on temperature. It can identify the location of the fire point from the measurement data of semiconductor temperature sensors embedded at regular intervals (5m or 8m) within the cable. It reliably detects the fire point location compared to conventional equipment, activates appropriate emergency equipment and wind speed zeroing control, and issues a preliminary alarm approximately 30 seconds after the sensor detects a temperature anomaly due to a fire.

This is a power panel responsible for next-generation tunnel ventilation.

This is a ventilation power panel for jet fans that implements noise countermeasures in industrial inverters. By controlling the rotation speed of the jet fan, it creates a desired airflow speed in the tunnel. It uses a uniquely developed filter to reduce the negative impact of noise on the jet fan and other equipment. Precise control of the rotation speed is expected to improve energy efficiency and safety. For more details, please refer to the individual catalog.

2025 Drainage Treatment Course We are offering three courses online: Basic Law, Basic Management, and Knowledge Enhancement! This year, the courses are scheduled for May, July, September, November, and January 2025. Applications are currently being accepted. We look forward to your application.

The 34th Environmental Forum will be held on Thursday, June 5, 2025. The Environmental Forum is an event organized by our company in June, which is Environment Month, to encourage many people to think about environmental issues. [Content] Coastal areas that have increased biological productivity and biodiversity due to human involvement are referred to as "satoumi" (satoumi means "sea of the village"). In Part 1, we will introduce what satoumi creation is and how it is developed, using real examples. Additionally, various conservation activities for biodiversity are being carried out in different forms, starting with satoumi creation. In Part 2, we will discuss the current status and future prospects of biodiversity conservation, starting from satoumi. Participation is free of charge. [How to Participate] ZOOM Webinar or Wink Aichi (venue) [Program] 13:30 Opening Remarks 13:45 Part 1: Creating Satoumi Aiming for Coexistence of "People" and "Nature" 14:45 Break 15:00 Part 2: The "Present" and "Future" of Biodiversity 16:00 Part 3: Q&A Session 16:30 Closing Remarks

We are pleased to announce the archive distribution of our seminar titled "Easily Create User-Friendly Manuals for Both People and Generative AI with StockNaut." We will provide a clear explanation of the kintone plugin "StockNaut," which allows you to write text while pasting multiple images into a multi-line text field. The "Markdown syntax" adopted by StockNaut enables the creation of text that is easy for both people and generative AI to read. By combining generative AI, you can experience the benefits of StockNaut at 120%! If you are having trouble with document creation, including manuals, we look forward to your participation. 【Timetable】 - Introduction to StockNaut - Introduction of internal use cases at FCS - Demonstration of the combined use of StockNaut and generative AI - Q&A session We look forward to your applications.

Silex will exhibit at the "Embedded Edge IoT Development EXPO [Spring]" held at Tokyo Big Sight from April 8 (Wednesday) to April 10 (Friday), 2026, showcasing next-generation wireless and edge AI solutions that integrate our long-developed connectivity technology with the latest edge AI, under the theme of "Uninterrupted Wireless + Edge AI Technology."

Nitto Kohki will exhibit at the "Data Center EXPO" held at Makuhari Messe Hall 1 from Wednesday, October 23 to Friday, October 25. [Booth Number: A6-23] At this exhibition, we will showcase the "Compact Zero Spill Coupler," which is specifically designed for data centers, including supercomputers. We will also present the "Blind Mate Type," a fitting exclusively for server cooling piping, as a reference exhibit.
