Lightweight, long-length, high strength, and excellent insulation performance! It is a high-performance freeze prevention pipe!

GNGWDA is increasingly being adopted for bridge attachments and suspended piping due to its unique characteristics of lightweight, flexibility, and earthquake resistance that are not found in other types of pipes. Nominal diameter: W40 to W100 (The conduit dimensions conform to ISO standards.) 【Features】 ○ The composite pipe structure of polyethylene and aramid fibers provides high internal pressure strength, and the corrugated steel pipe structure protects against external pressure. ○ The rigid polyurethane insulation layer prevents the freezing of fluids inside the conduit. ○ Pipes with a nominal diameter of W100 or less can be delivered to the site as long-length pipes (tab-wound). ○ The use of long-length pipes allows for labor-saving in construction and shortening of construction periods, leading to cost reductions. ○ They are long and highly flexible, allowing for bending while extending the pipe. ○ They are ideal for soft ground such as marshy areas and reclaimed land, and they also excel in earthquake resistance. ○ The outermost layer is coated with low-density polyethylene with added carbon black, providing excellent weather resistance and corrosion resistance, making it suitable for exposed pipes. ○ The EF fusion and automatic butt fusion create a reliable pipeline with a unified structure. ○ It possesses sufficient weather resistance and internal and external pressure strength as a bridge attachment pipe.

In recent years, the implementation of maintenance DX to achieve "non-stop factories" has become an urgent necessity in manufacturing sites. Amid the trend of factory IoT and data utilization, the use of remote I/O, which can remotely aggregate and collect sensor information and control signals from equipment and sensors dispersed inside and outside the factory, is gaining importance as a foundation for predictive maintenance and condition monitoring. On the other hand, the installation environment for remote I/O is not necessarily limited to control panels or well-conditioned factory interiors. There is an increasing need to collect data in harsh environments, such as outdoor equipment and conditions involving high temperatures, low temperatures, vibrations, and strong electrical noise. Conventional remote I/O systems have struggled to operate stably under such conditions, requiring measures like installation location constraints and additional protective enclosures. Environmentally robust remote I/O with wide temperature support and noise resistance can address these challenges, enabling the expansion of the scope of factory IoT and predictive maintenance to outdoor and remote equipment. In this seminar, we will introduce the lineup of Contec's environmentally robust remote I/O, the "CONPROSYS(R) Robust I/O Series," which includes a total of 23 products.

[Lecturers] Nishimura & Asahi Law Offices, Foreign Law Joint Enterprise Attorney and Associate Iku Akamatsu Attorney and Associate Yasukazu Yamazaki (Note: "Saki" is a variant character) [Key Lecture Content] In the logistics sector and other areas, discussions are underway regarding the social implementation of drone flight routes. Drone flight routes involve various stakeholders, including drone route operators, drone operation businesses, surrounding municipalities, and ground-related parties, who collaborate and divide roles to realize these routes. Therefore, drone route operators and businesses utilizing drone routes need to enter into contracts regarding the use of drone routes with relevant parties, clarify roles, and implement appropriate risk management. This lecture will explain the legal points that must be considered when entering into contracts for the use of drone flight routes. [Lecture Items] 1.

[Speaker] Daisuke Imaizumi, President and CEO, Infra Commons Inc. [Key Lecture Content] When companies expand their overseas operations, obtaining reliable market research and regulatory information is essential. However, reliance on traditional paid databases and specialized research firms has become a significant burden in terms of both cost and time. This seminar will introduce a new approach to overseas market research using generative AI. Specifically, we will cover a wide range of use cases, including understanding the distribution structure of niche markets, extracting key points from financial reports and research materials, collecting and summarizing information in local languages, exploring potential M&A candidates and investment trends, organizing key points of EU regulations, monitoring trends by industry and country, and understanding trends in defense and geopolitical risks. For each theme, we will specifically explain the selection of information sources, efficient research procedures utilizing generative AI, and methods for verifying sources, allowing participants to gain insights that they can immediately apply to their own work. This content is ideal for those who regularly handle overseas information in areas such as corporate planning, overseas business, new business development, and research departments.
