Report on Participation in the "Annual Forum 2025" of the Defense Facilities Society

A reinforced soil wall with a proven track record of absorbing large-scale impacts using reinforced soil.

The "Geo-Lock Wall" is a reinforced earth wall designed to absorb falling rocks, landslides, and collapsing soil, primarily along roadsides and behind residential houses. It can withstand rockfall energy of up to 5500 kJ and is utilized for a wide range of rockfall countermeasures from small to large scale. It primarily uses soil and geosynthetics as materials. Due to the unique flexible structure of soil structures, it efficiently absorbs impacts and can handle large-scale impact energy. Because it is a soil structure, it can be installed in various terrains, including sites with limited installation space, sites with vertical gradients, and sites with valley topography. Additionally, it does not transmit impact forces to the supporting ground, so in most cases, ground improvement treatments are not necessary. ■ Rockfall, landslide, and collapsing soil countermeasures using reinforced earth ■ Capable of withstanding rockfall energy up to 5500 kJ ■ Available in three types according to the scale of rockfall ■ Over 540 adoption records nationwide Ministry of Land, Infrastructure, Transport and Tourism New Technology Information System (NETIS) Registration Number: HR-990009-V *Registration period has ended NETIS Fiscal Year 2016 Semi-Recommendation Technology *For more details, please download the PDF or feel free to contact us.

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.
