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.

■Connecting Biomarker Discovery to Clinical Application - Explained with Real Cases of Neurodegenerative Diseases Although biomarkers are discovered, many do not reach clinical application. The reasons for this lie in multiple hurdles that arise after discovery, such as "narrowing down candidates," "reproducibility," and "connecting to clinical practice." 1. How should promising candidates obtained from comprehensive exploration be narrowed down? 2. How can reproducibility and scalability be ensured? 3. What are the key points for smoothly transitioning to clinical research? 4. What should be considered in data science throughout the overall flow? In this online seminar, we will clearly explain specific strategies for advancing from discovery to clinical application based on actual research cases of Alzheimer's disease and multiple sclerosis, in an easy-to-understand manner in Japanese. *Olink products and services are for research purposes only. Please note that they cannot be used for diagnostic purposes.
