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. (Registration name: "Temperature Detection Type Fire Point Detection Device" KK-140022) *For more details, please refer to the PDF or feel free to contact us.

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.

In the evaluation of GaN HEMTs, DC measurements alone cannot capture the true behavior of the device in actual operation. Phenomena such as current collapse caused by self-heating and trap effects can lead to RF output degradation and reliability deterioration. In this free online seminar, top researchers from the United States will present the latest evaluation workflow that integrates pulse IV measurements, RF characteristic evaluation, and thermal reflection imaging. The seminar will be conducted in English without interpretation, so please join us. 【Main Program】 Analysis of correlation data for pulse IV/RF/thermal reflection imaging of GaN devices Thermal degradation mechanisms of GaN, SiC, etc., and their impact on reliability Exceeding the limits of IR (infrared) with picosecond resolution thermal reflection imaging Automated wafer-level evaluation system for RF/silicon photonics 【Event Overview】 Date: May 27, 2026, 7:00 AM or 7:00 PM (PDT) *Japan Time: May 27 (Wed) 11:00 PM or May 28 (Thu) 7:00 AM Participation Fee: Free (online broadcast with live Q&A) This seminar is packed with tips for next-generation device development. Please register!

Are you facing challenges where salary increases don’t necessarily lead to higher take-home pay? In this seminar, together with a certified social insurance and labor consultant, we will explore future HR strategies from both perspectives: system design and practical implementation. ✔ HR strategies under inflationary pressure ✔ Rethinking compensation and benefits design ✔ Real case studies for improving hiring & retention ✔ The concept of the “third wage increase” and how to apply it ―――――――――― ■ Event Details Date: May 27, 2026 (Wed) 18:30–20:00 Location: Kort Valuta Inc.
