Title: Keita Yoshihara: Innovator in Bonding Technologies
Introduction
Keita Yoshihara is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of bonding technologies, holding a total of 2 patents. His innovative approaches have paved the way for advancements in the bonding of various materials.
Latest Patents
Yoshihara's latest patents include a method and apparatus for bonding workpieces together. This invention addresses the challenges of aligning and bonding two workpieces, which can be composed of resin or glass substrates. The method ensures that issues such as alignment shifts and breakage are minimized while maintaining uniform bonding. The process involves placing a first workpiece on an inverting stage and a second workpiece on a work stage, followed by the application of UV light. The inverting stage is then rotated, allowing the workpieces to overlap and be pressurized for pre-bonding. Afterward, the pre-bonded workpieces are heated to a predetermined temperature to complete the bonding process.
Another significant patent is a light processing apparatus that irradiates ultraviolet light onto a workpiece with a specific pattern formation. This apparatus includes a light-emitting unit with an ultraviolet irradiance lamp and a light transmitting window. The design ensures that one side of the light transmitting window and the pattern formation portion are not parallel, enhancing the effectiveness of the light processing.
