Title: Masaki Fujii: Innovator in Injection Molding and Toner Recovery Technologies
Introduction
Masaki Fujii is a prominent inventor based in Hachioji, Japan. He has made significant contributions to the fields of injection molding and toner recovery technologies. With a total of 2 patents to his name, Fujii continues to push the boundaries of innovation in his industry.
Latest Patents
Fujii's latest patents include an advanced injection molding method. This method involves injecting resin into a mold cavity while maintaining a specific pressure ratio. The process ensures that the cavity surface pressure is not less than 0.65 times the cylinder pressure of the injection molding device. Additionally, a first pressure keeping process is conducted to maintain constant cylinder pressure after the filling step. The cylinder pressure is then increased to ensure that the cavity surface pressure is at least 0.95 times greater than the pressure at the time of filling. A second pressure keeping process is implemented to maintain this increased pressure until the cavity surface temperature drops below the glass transition temperature of the resin.
Another notable patent is the toner recovery device. This invention provides a mechanism for removing toner from the surface of a photoreceptor using a cleaning device. The collected toner is then stored in a container. The image forming apparatus features a stationary member with a toner inlet and an opposite end. The toner recovery apparatus includes a driving device that moves the container back and forth along the stationary member. Bumper means are fixed to the stationary member to collide with the container, applying negative acceleration to halt its movement.
