We will exhibit at the 22nd Mechanical Components Technology Exhibition.

Successfully eliminated loosening permanently with our safety bolts and nuts! Cleared JQA high-speed vibration loosening test! Samples will be distributed at the Mechanical Element Technology Exhibition!

The "Yurumanzo (W-V-LOCK)" is a safety bolt and nut that successfully eliminates loosening permanently by adopting a ratchet mechanism between the bolt, nut, and washer, and by incorporating protrusions on the bottom surface of the washer that bite into the workpiece. All five units tested in the vibration loosening comparison test conducted by the Japan Quality Assurance Organization passed without loosening for over 17 minutes. 【Features】 ■ The bolt and washer are connected using a ratchet system, with several protrusions on one side of the seating surface. ■ The protrusions bite into the tightened object in a wedge shape, preventing the washer from rotating and providing a loosening prevention effect for the entire screw. ■ No loosening occurs even under strong vibrations or long-term use. ■ A high safety and durability loosening prevention mechanism for screws. ■ Patent obtained. * For more details, please request documentation or view the PDF data available for download.

This webinar will focus on Restek's newly announced GC column "RMX Series," explaining the analytical performance achieved through the latest passivation treatment technology and approaches to solving challenges in sample analysis that includes complex matrices. We will introduce the unique features of the new column format specific to the RMX Series and practical points for trace analysis, along with analysis examples using actual samples. We will also concretely present the applicability to routine analysis through actual case studies using the RMX Series. (External speaker: Mr. Eduardo from Weck Laboratories / Japanese dubbing) What you will learn in this webinar: - The features of the advanced passivation treatment technology adopted in the RMX Series GC columns and its analytical advantages. - The concepts for achieving high-sensitivity analysis at trace levels for a wide range of components, including acidic, basic, and neutral compounds. - Common challenges faced in complex sample analysis and solution approaches utilizing the RMX Series. - How selecting the optimal GC column format, including the RMX Series, can lead to improvements in analytical efficiency and lab operations.

[Speaker] Yoshio Sato, Department Manager, Network Services Division, NTT Limited Japan, Service Department [Key Lecture Content] We will organize the fundamentals of the submarine cable business, changes in the international communication market and industry structure, and the necessity of establishing a new company. International traffic has repeatedly evolved in quantity and quality, making low latency, stability, and redundancy essential. On the other hand, the traditional consortium model has limitations in addressing construction costs, timelines, and uncertainties. In response to these environmental changes, we will redefine infrastructure from "service" to "product," aiming for the establishment of a new company that balances risks and growth opportunities, and outline the direction of the next-generation digital infrastructure envisioned by the NTT Group. [Lecture Items] 1. Basic knowledge of the submarine cable business 2. What has changed in the international communication market (business background) 3. How has the structure of the submarine cable industry changed (industry structure) 4. Limitations of the traditional model 5. Why was it in the form of a "new company"? 6. Q&A / Business card exchange
