A rich selection of pipes, fittings, and irregular pipes allows for detailed responses to user needs!

WED pipes are dual-layer pipes made of high-density polyethylene, available in sizes that conform to ISO standards. Nominal diameter: W40 to W350 【Features】 ○ It applies the international standard ISO4427, which originated in Europe, where the penetration rate of polyethylene pipes is the highest in the world. This allows for the use of a wide variety of fittings. ○ Made from black high-density polyethylene with excellent weather resistance, making it suitable for exposed piping. ○ Pipes with a nominal diameter of W100 or less can be delivered in long lengths (tab-wound). ○ The delivery of long-length pipes can reduce labor and shorten construction time, leading to cost savings. ○ Polyethylene pipes are flexible and have excellent seismic resistance.

Impact of IC Heat Generation - Definition of Thermal Resistance, etc. 2. Thermal Design of LDO and DCDC - How to Determine Tj 3. Losses, Heat Generation, and Thermal Shutdown of LDO 4. Losses in DCDC 5. Case Studies 6. PCB Design 7. Thermal Design Support 8. Q&A We look forward to your participation.

We will be exhibiting for the first time at the "Okayama Technology Exhibition 2025 - A Technology Exhibition and Business Meeting to Meet Elite Companies" held at Convex Okayama on November 12 (Wednesday) and 13 (Thursday). At the Amada booth, we will showcase and demonstrate three machines: a bending machine, a sheet metal cleaning machine, and a super alkaline ion water generator, presenting the latest technologies in bending processing and environmental solutions for manufacturing sites. [Highlights of the Amada Booth] ■ Electric servo bending machine designed for ease of use based on ergonomic principles A servo bending machine that considers both people and the environment. It allows work to be done while seated, freeing operators from standing tasks. Additionally, various supportive features enable quick and high-precision bending processing, even for those who are not skilled. ■ Super alkaline ion water that significantly improves degreasing and cleaning work environments By utilizing "Super Alkaline Ion Water SAIW," which demonstrates high cleaning power without the use of chemicals, we achieve stable cleaning quality while reducing environmental impact. *Pre-registration is required for attendance via the "Okayama Technology Exhibition" website.

From October 28 to 30, 2025, at Nihonbashi Mitsui Hall, we plan to introduce products related to satellite spectral data, including a hyperspectral camera for satellites, at NIHONBASHI SPACE WEEK 2025.

We will be exhibiting at the following trade show. Our company will showcase various types of polyethylene pipes. We sincerely look forward to your visit. Trade Show Name: 10th National Small Hydropower Generation Conference in Saitama

Pogo pin connectors are essential components in today's technology industry, achieving excellent durability and stable electrical contact. However, this does not mean that market failures do not occur. To use them correctly and maximize their functionality, meticulous planning and precise engineering are required. They are widely used across various industries, including home appliances, automotive systems, medical devices, and aerospace technology, and further demand expansion is expected in the future. Therefore, learning from failure cases and implementing proper measures during the evaluation and design stages contributes to ensuring the reliability of the equipment. In this webinar, we will provide an excerpt from the "Failure Analysis Cases of Pogo Pins" presented by our company, Eurofins FQL, at the Reliability, Maintainability, and Safety Symposium hosted by the Japan Science and Technology Agency on July 17, 2025, due to its popularity.
