Latest Patents

Among his latest patents is the "Rotatable head type electrophotographic apparatus." This invention features a rotatable head supported on a movable table, equipped with a corona charging electrode and a light source. The design allows for the formation of an electrostatic latent image in photosensitive material as the head rotates and moves above it. The latent image is developed immediately by processing liquid flowing in the development processing unit.

Another notable patent is the "Process for thermal development and transfer." This process involves a photosensitive material containing a hydrophilic pigment that is exposed to light to create a pigment pattern. The material is then brought into contact with an image-receiving material, and both are heated to facilitate the transfer of pigment. A pigment diffusion assistant is used to enhance the transfer process.
