We have launched a special page for CPC quick couplings.

CPC couplings are top-class couplings for plastic tubes with over 30 years of history.

CPC couplings are products that excel in both functionality and design, featuring a precision hose barb integrated with the main body, a shut-off valve that blocks the flow path when disconnected, and a push-button thumb latch that allows for quick connection and disconnection. The unique thumb latch mechanism from CPC enables speedy and reliable operation without requiring specific skills from the operator. Additionally, the ability to freely choose whether or not to include a valve that blocks the flow path during disconnection makes it ideal for applications where liquid spillage is undesirable. The wide range of sizes, designs, and selectable materials has garnered strong support across various fields, including medical and beverage industries.

From July 15 (Tuesday) to July 20 (Sunday), 2025, the "42nd Daihatsu Japan Open 2025 Badminton Championships" was held at the Tokyo Metropolitan Gymnasium. We would like to report on the motion capture experience session conducted by Yonex Co., Ltd. at the venue. During the experience session, participants were asked to swing three different types of rackets from different generations, focusing on whether there were differences in their top speeds. The measurement was conducted using the same Raptor-12HS system utilized at the Yonex Performance Innovation Center (Blue Lab). This was a valuable opportunity to experience the research equipment that is not currently open to the public and to see what kind of measurements are being conducted! ---[Yonex Co., Ltd.

Hello, this is the public relations department of KAITAKU Co., Ltd. in Okayama City, Okayama Prefecture! Recently, our wooden lightweight hyper CLT sheet has been officially registered with the Ministry of Land, Infrastructure, Transport and Tourism (NETIS number: TH-250021-A). The decisive difference between hyper CLT sheets and conventional temporary materials lies in the "exit" after their durability period ends. The hyper CLT sheet (NETIS number: TH-250021-A) is not discarded after its role on site is finished; instead, it is reused as chip fuel for biomass power generation. • Made: It is made from **wood (thinned timber)**, resulting in low environmental impact. • Used: It significantly contributes to reducing CO2 on site. • Converted to energy: Once its durability period is over, it becomes chip fuel for biomass power generation, ensuring that no resources are wasted. In this way, a **"complete circular" system** is established that connects materials to energy. Additionally, these initiatives can serve as a strong appeal for creativity related to construction performance. Please try the hyper CLT sheet (NETIS number: TH-250021-A)!

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out even in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.

About a month ago, I took the Sanyo Electric Railway to the Hanshin Electric Railway express train from Himeji to Osaka on a Sunday. The important point here is that it was a "Sunday." The decisive difference from usual days is that there were "families" on board. I had somewhat anticipated this, but nowadays, almost 100% of parents are completely absorbed in their smartphones, ignoring their children who might be standing behind the driver's seat, shouting, or doing anything else. In fact, they even hand another smartphone to their child, effectively using it as a babysitter. At this rate, it's no wonder that these children will grow up to be adults with communication disorders.
