Sifangda: Announcement on obtaining a patent certificate

**Abstract** Stock Code: 300179 Securities Abbreviation: Sifangda Announcement No.: 2013-032 Henan Sifangda Superhard Materials Co., Ltd. announces the receipt of a utility model patent certificate from the State Intellectual Property Office. The company and its Board of Directors confirm that all information provided in this announcement is accurate, complete, and free from any false statements, misleading information, or material omissions. The patent, titled "Polycrystalline Diamond Composite Pick," is registered under Patent No. ZL201220735269.0, and the patentee is Henan Sifangda Superhard Materials Co., Ltd. This utility model was authorized and announced on June 12, 2013. The innovation involves a unique method for fixing the tooth head and tooth tip of the polycrystalline diamond composite pick. Instead of traditional methods, the design uses a protrusion and matching groove to secure the components before welding. This approach significantly increases the contact area between the tooth head and tip, enhancing the welding strength and reducing the risk of the tip breaking off during drilling operations. As a result, the service life of the pick is extended, contributing to improved performance and efficiency in hard rock excavation. The acquisition of this patent is an important milestone for the company. While it may not have a direct impact on current production and operations, it plays a crucial role in protecting the company’s intellectual property, fostering continuous innovation, and strengthening its competitive edge in the market. This announcement is made in accordance with applicable regulations and aims to provide transparency to shareholders and stakeholders regarding the company's ongoing technological advancements. **Board of Directors** Henan Sifangda Superhard Materials Co., Ltd.

Optical Glass Flat Mirror

Optical Flats mirrors are ideal for a variety of applications including interferometry, imaging systems, laser applications, optical path folding, and autocollimation. These mirrors are available in a variety of coating and substrate options, along with surface flatness options of λ/10 and λ/20.  Fused Silica, is optically clear and features excellent resistance to abrasion and high durability, making it the best choice for applications in harsh environments.

The mirrors are available in circular, square, and rectangular dimensions. Rectangular first surface mirrors are ideal for applications requiring the mirror to be mounted at 45° in order to produce a 90° bend in the light path.

Protected metallic coatings provide a moderate level of reflection over a very broad spectral range and are widely used as mirrors. These coatings are protected by a thin layer of dielectric material in order to make them durable. Enhanced metallic coatings provide greater reflection across the operating band width. These coatings are enhanced by adding a multilayer dielectric stack. Metal coatings will modify the state of polarization of an incident beam of light and are therefore inappropriate for most polarization sensitive applications.
