Japan-Japan Tokyo-Metal has introduced an innovative spring washer called "YOSHER," designed to prevent bolts and nuts from loosening or falling off. This new development represents a significant evolution in the field of fastening technology, offering a simple yet highly effective solution to a common problem.
The YOSHER spring washer works on a unique principle: when the gasket is tightened in a twisted state, its inherent restoring force helps maintain a secure connection. Unlike traditional washers, YOSHER's design ensures that it grips the screw’s surface more effectively, reducing the chances of loosening due to vibration or movement. This innovation not only enhances safety but also minimizes the risk of accidents caused by loose components.
At the core of YOSHER's design is the concept of "safe and secure auxiliary hardware." The inner diameter of the washer is shaped to match the threads of the screw. When the nut is tightened, part of the YOSHER washer bites into the screw’s thread, creating a strong, continuous rebound force between the metal base and the nut. This feature ensures a stable and long-lasting connection, making it ideal for use in various industrial and mechanical applications.
What makes YOSHER stand out is its simplicity and effectiveness. It doesn't require any special tools or installation techniques—just a standard tightening process. This ease of use, combined with its high performance, makes it a valuable addition to any toolbox or manufacturing setup.
Whether you're working on machinery, automotive parts, or construction projects, YOSHER offers a reliable way to keep your fastenings secure. Its advanced design and practical functionality make it a game-changer in the world of hardware solutions.
Double-concave Cylinder Lens
Cylindrical lenses have at least one surface that is formed like a portion of a cylinder.Cylindrical lenses are used to correct astigmatism in the eye and in rangefinders, to produce astigmatism,stretching a point of light into a line.They are available in either plano-concave or plano-convex configurations. Plano-Concave Cylindrical lenses have a negative focal length and are used for image reduction or to spread light. Plano-Convex Cylindrical lenses have a positive focal length, which makes them ideal for collecting and focusing light for many imaging applications.
Some styles of cylindrical lenses have antireflective coatings to increase the transmission of light through the lens. Fused silica cylinder lenses are ideal for demanding laser machining and medical applications.
