While we cannot conduct live demonstrations, we would appreciate it if you could try them on and provide your feedback regarding their appearance and wearing comfort. We will be at the venue for all three days, so please feel free to greet us when you visit.

Hydrogen flames are not visible due to the lack of visible light and their colorless, transparent nature. In the hydrogen supply chain, no matter how advanced the fail-safes are, human or mechanical errors can occur. From the perspective of preventive maintenance and functional safety, please experience the need to make the invisible hazard of hydrogen flames apparent.

The realization of odorless hydrogen supply through pipelines, assuming large-scale hydrogen transport in the future, requires leakage hydrogen detection as a substitute for odor detection. Therefore, our company has been developing a multi-point leakage hydrogen monitoring network system in collaboration with Iwatani Corporation, utilizing the Kitakyushu City Environmental Future Technology Development Grant, and has completed a three-year demonstration starting from the fiscal year 2019. In the development for fiscal year 2021, we conducted demonstrations at the 'Hydrogen Pipeline Leakage Simulation Evaluation Facility' established at the Kitakyushu Eco-Town Center, focusing on response tests of wireless hydrogen sensors and hydrogen selectivity evaluations in mixed gas environments. We also verified the appropriate pitch between handholes while varying the conditions of sensor response time and distance from the hydrogen leakage point. By continuously disseminating reliable evidence obtained from this research and development from Kitakyushu City, we believe it will contribute to the early utilization of odorless hydrogen and the establishment of a hydrogen supply chain.

[Exhibition Schedule] Spatial Representation of Wind Sensor at KOA Corporation Booth A wind sensor with outstanding responsiveness will be showcased at the Sensor Expo. Our software (3D + real-time timeline) will be utilized, and a representative from our company will participate.

[Article Publication] Development of a Multi-Point Hydrogen Leak Monitoring Network The overall theme of the magazine is "Decarbonization." Currently, we are conducting a demonstration of buried hydrogen pipelines in the final year, but we must advocate for a safe and secure system that replaces the odor associated with hydrogen. If we don't, we risk becoming isolated like the Galapagos and losing in international competition, which I felt compelled to write about with a sense of responsibility.

We will advance the feasibility study by combining the basic technology of hydrogen "flame" detection from Shikoku Research Institute with our technology that makes measurement data easily understandable to anyone.

Our company has been featured as a 'shining company in the region.'

On the product information page of the environmental testing laboratory, images of our spatial visualization measurement (TempLAN) and real environment representation software (SpaceSight) are introduced.

◆Koken Co., Ltd. https://www.youtube.com/channel/UC0a3buURm07mrPgeBBAb_nw Marketing as a sales company for measuring instruments is difficult. If we only rely on the manufacturer's marketing and focus solely on sales activities, it feels like we are not connecting with the users. To change our perspective, I had my subordinates create a video. The concept is, "A video that does not adopt the perspective of the creator." It has turned into a sort of social studies field trip, but this could become a unique characteristic in its own right. This clean system is also purchased by our technology group, and since it is portable, it always seems like someone is setting it up somewhere. It is similar to the concept of MieruTIME4D, where it can be set up quickly, measured swiftly, and taken down just as fast, which is great.

An article about the hydrogen pipeline demonstration was featured briefly in the electronic edition of the Nikkei. During the coverage of the Kitakyushu Hydrogen Town, Iwatani Corporation was the main focus, but I think the reporter was considerate of me as I passionately explained things on my own. The development of the multi-point hydrogen leak monitoring network is also in its final year, and my motivation has increased. I will keep doing my best.

The evaluation of power semiconductors involves testing under high voltage/high current conditions, which is very dangerous. In particular, even if the power supply is turned off, the state where the capacitors have not discharged remains "high voltage," posing a risk to life. This testing environment was created in collaboration with Professor Omura from Kyushu Institute of Technology, with the principle of "putting the safety of students conducting dangerous tests first" in mind, and it incorporates mechanisms for hazard avoidance. We also offer units and tabletop racks for sale. We look forward to your inquiries.

Our Nagasaki staff seems to have chosen to relocate for further advancement. After ten years of hard work since the launch in the town of faith, Urakami, I feel a bit sad that the best fried chicken shop in Kyushu will be farther away due to this move. http://www.saisakiya.com/shop/tsukimachi/#menu The new location is near Nagasaki University. → To our partner companies, please continue to support them.

This year, as a member of the Fukuoka Hydrogen Energy Strategy Conference, we will be exhibiting the "High Sensitivity Hydrogen Selective Detection System" to realize the utilization of odorless hydrogen. Date: February 26 (Wednesday) to 28 (Friday) 10:00 AM to 6:00 PM (until 5:00 PM on the last day) Venue: Tokyo Big Sight, West, South, and Aomi Exhibition Halls Our booth number: West Hall 4 W26-40

The products scheduled for exhibition are devices developed in collaboration with the Forestry and Forest Products Research Institute, Kyushu University, and Sumitomo Forestry Co., Ltd., which can automatically select the presence or absence of lipids (ovules) necessary for seed germination, contributing to improved selection of germination rates and increased efficiency in forestry.

From December 12 (Wednesday) to 14 (Friday), the HD-PLC Alliance will exhibit at the "Smart Building EXPO" (Tokyo Exhibition) held at Tokyo Big Sight (3rd Housing, Building, and Facility Week 2018). This will be our second participation following last year, but unfortunately, we will only be presenting the "Evaluation Environment Device DisLINE" catalog and a video on "Measurement Methods" this year due to the unavailability of our staff for explanations. If you need further details, please do not hesitate to contact us. Thank you very much.

We will be exhibiting the "Advanced Seed Sorting Device" (production version) at the booth of the Forestry and Forest Products Research Institute, just like last year. The Agribusiness Creation Fair 2018 is a "technology exchange exhibition" held to clearly present the latest research results in the fields of agriculture, forestry, fisheries, and food from institutions across the country through displays and presentations, and to promote collaboration between research institutions and businesses. We would be grateful if you could stop by the "booth of the Forestry and Forest Products Research Institute" when you visit this exhibition.

We will participate in a networking event where small and medium-sized enterprises with excellent technology and university researchers from all over the country gather, and we will promote our "seeds" centered around "measurement technology," seeking new collaboration and exchange between companies.

We will introduce products and technologies that are most suitable for the theme of the exhibition, "Environmental solutions such as low-carbon and global warming prevention technologies and purification and pollution prevention technologies appropriate for the era of the global environment." Exhibit: Hydrogen Visualization System (Booth No. EN-05) This is a fusion of our multi-point synchronous measurement technology and cutting-edge sensors. Please feel free to stop by our booth.

There will be a presentation of products from chip vendors based on the latest HD-PLC technology, and we will introduce evaluation methods for high-speed power line communication from our company.

The RIST Forum will focus on the theme of "Japan's first demonstration test of a widespread EV bus and initiatives involving industry, academia, government, and the private sector."

This product was developed in collaboration with Nishi Nippon Gas Co., Ltd., Japan Gas Co., Ltd., and Miyazaki Gas Co., Ltd. with the support of the H29 fiscal year JGA project, and has been undergoing trial sales since the H30 fiscal year.

We developed a wireless measurement system that synchronously measures spatial temperature at multiple points in collaboration with Chubu Electric Power Co., Ltd., expressing it in 4D (XYZ axes + time axis). Kyushu Measuring Instruments' "Spatial Visualization System" is a "multi-point synchronous measurement system" widely adopted in environmental testing rooms and comfort testing rooms of air conditioning manufacturers. By adding the development concept of "mobility" to this system, we have successfully developed a wireless measurement system in collaboration with Chubu Electric Power. For visualizing indoor environments, such as "temperature unevenness due to heat discharge from equipment" and "heat accumulation" in factories and restaurants, real-time measurement in actual environments and reliability through synchronous measurement are required. This system has achieved time savings in "measurement preparation (installation/removal)," which was a problem in actual measurements, and the measurement data obtained by this system is optimal for analysis and analytical data for "energy solution services." Since December 1, 2017, Chubu Electric Power has started a measurement service using this system as part of its "service to provide optimal utilization of energy." Orders will begin in February 2018, with a sales target of 30 units per year.

We will exhibit the SPR (polymer film thickness measurement device) at the "nano tech 2016" event held at Tokyo Big Sight from January 27 to 29, 2016, at the Kyushu University Academic Research City (OPAC) booth. *Joint research with Professor Keiji Tanaka from Kyushu University.

In the "Kyushu University Special Feature" of the Nikkan Kogyo Shimbun (11/30), we are promoting through an advertisement. Please check the press release summarizing the "Hydrogen Visualization System," which has been adopted for the next-generation rocket tests by ISAS/JAXA.
